How to make heating a greenhouse with your own hands: a comparison of different methods of heating. Greenhouse heating: options and features Heating systems for home greenhouses

The greenhouse allows you to get a crop when other gardeners are still watering or planting their plants. The greenhouse allows you to grow early products thanks to the heating of the greenhouse with your own hands, since the heat of the sun allows the crop to grow only in the summer. Thanks to this design, fresh products can be grown even in winter. The minimum allowable temperature in the greenhouse should be +18 degrees. However, in order to obtain such conditions, impenetrable walls alone will not be sufficient.

The most economical will be the installation of a greenhouse in the place where the thermal route passes. In such a situation, it is only necessary to find the most good place and you can start building a greenhouse. In other situations, the construction of a greenhouse will be a more complicated process, but it can also be done by hand - just like heating a greenhouse with your own hands.

Heating with solar panels

It is possible to heat a greenhouse structure and make home-made heating in a greenhouse using sunlight. The first stage in the construction of the greenhouse will be a hole in the hole about 15 cm deep. Next, the ground must be covered with a layer of polystyrene or other heat insulator. From above, this is all covered with a layer of polyethylene film to provide waterproofing. Wet sand is placed on the film and covered with earth. This type of device, although quite simple, can nevertheless maintain the optimum temperature in the greenhouse.

You can do in the greenhouse and simple air heating of greenhouses with your own hands. The simplest method for heating a greenhouse is air heating - good decision the question of how to make heating in a greenhouse, which is described below:

1. You need to take a piece of steel pipe with a length of 2 to 2.5 m and a diameter of 50 to 60 cm.
2. Under one end of the pipe, you need to kindle a fire, and insert the other end into a greenhouse covered with a film.
3. The fire must be maintained at all times. The air in the tube will heat up fairly quickly, and the plants will get the warmth they need.

This method of heating, at the same time, is one of the easiest, but also the most inconvenient, since the fire must be maintained all the time.

Heating the greenhouse with gas

The main advantage of gas is that, in terms of supply, it is much more stable and accessible than a campfire. In order to winter period to heat the greenhouse, you do not need to conduct gas from the house to the greenhouse, as this is not entirely advisable. Also, such a scheme for heating a greenhouse will require some costs. It is best to purchase several cylinders of gas, which should be enough. However, it is worth paying attention to the fact that too many carbon dioxide may result in plants not growing properly.

Also, poor ventilation of the greenhouse can also affect the negative growth of plants. It will also be necessary to install a means for extracting combustion waste into the greenhouse.

The heaters that will be used for your greenhouse must be equipped with special sensors.

They are necessary so that in the event of a cessation of combustion and the release of gas into the air, such devices immediately work and shut off the gas supply to the burner.

Heating a greenhouse with a solid fuel boiler

Such projects of greenhouses with heating can be located both in the greenhouse itself and outside it in any other room. The second option has some advantages, since in order to add fuel or wood to the fire, it will not be necessary to go to the greenhouse. The disadvantage of this option is that if the boiler were located directly in the greenhouse, it would also emit some heat.

In the heat generator, you need to add fuel only twice a day. Moreover, from the point of view fire safety, such a do-it-yourself winter greenhouse does not pose a threat. Thanks to this parameter, it can be safely left unattended all night. Another advantage of the boiler is that it requires a minimum consumption of fuel material.

Furnace heating of the greenhouse

Stove heating do-it-yourself greenhouses, compared to electric ones, do not burden financial costs so much. A simple stove for a greenhouse can be easily built with your own hands, while actually not spending any money.

The principle of the furnace for the greenhouse:

1. In the greenhouse vestibule, a furnace firebox made of bricks is laid out.
2. A chimney is laid out along the entire length of the greenhouse.
3. The chimney is removed from the greenhouse on the other side in order to carbon monoxide weathered, but the heat remained inside. The distance between the firebox of the greenhouse and its end side should be at least 25 cm. The distance from the bed with plants to the top of the hog should be at least 15 cm.

Before you build a greenhouse with heating with your own hands, you can explore another way:

1. We find a large barrel, with a volume of at least 3 cubes. Inside the barrel we paint in 2 layers to prevent the rust process.
2. Holes are made in the inside of the barrel, one of which is for the chimney, and the others for the expansion tank and for the tap.
3. We cook the stove and insert it into the barrel.
4. The chimney is removed from the barrel, and a pipe about 5 meters long is installed from the outside.
5. An expansion tank with a volume of 20 liters is mounted on the barrel, which must first be welded from ordinary sheet iron.
6. From a profile pipe, which has dimensions of 40x20x1.5 cm, the heating itself is brewed. The pipes must be laid out on the ground so that they are located at a distance of 1.2 meters. Such an arrangement of pipes will allow the soil to warm up in those places where the roots of the plants are located.
7. In order to ensure the circulation of water, for such home-made systems, it is necessary to purchase a special pump.

Hot water heating of the greenhouse

If we take the calculation of the heating of the greenhouse, then in comparison with other types, the arrangement of water heating of the greenhouse will be the most beneficial. Water heating do-it-yourself greenhouses - an electric water heater can be done simply:

1. It is necessary to take the body of the old fire extinguisher, and cut off the top of it.
2. A heating element with a working power of 1 kW is installed at the bottom of the fire extinguisher. Such a heating element can also be taken from an old samovar.
3. On top of the device, we make a removable type cover so that water can be poured into the heater.
4. We attach two tubes connected to the radiator to the body of the device. We fix the tubes with nuts and gaskets. In order for such a heater to work in automatic mode, you can use a circuit with an alternating current and voltage relay of 220V.

Register of pipes, where there is water and electric heater inside

When arranging a heating system for a greenhouse or greenhouse, the most important thing is to comply with all necessary instructions as well as safety regulations. A video on how to equip a greenhouse with your own hands can be viewed below.

Heated greenhouse allows you to have fresh greens all year round. In addition, it is possible to grow not only vegetables and flowers traditional for their latitude, but also heat-loving exotic plants up to pineapples and melons in Siberia or the Urals. Mounting the heating of the greenhouse with your own hands is quite realistic. There are several ways to efficiently heat a greenhouse. In this article, we will focus on each of them so that you can choose the best option for yourself.

How does the material affect heat loss

The choice of a heating system should first of all be based on the area of ​​\u200b\u200bthe greenhouse and the material from which it is built. Each type has its own heat loss coefficient. Most often for the construction of greenhouses use:

• glass - the heat loss coefficient is 5.5 W/kV.m;
• polyethylene film - K=12 W/kV.m;
• polycarbonate - 2.8 W/sq.m.

As you can see, cellular polycarbonate, due to its cellular structure, has the lowest heat loss rates, and polyethylene film, on the contrary, the highest. It is very important that the heating does not dry out the air in the greenhouse, and that the heat is distributed evenly over the entire area.

Best Options

Among the huge variety of options for heating greenhouses at home, we will consider only those that can be built independently without the help of professionals. So, the most common ways of home-made heating of greenhouses:

Electrical heating systems

Mostly practiced are ultraviolet lamps, which allow you to heat the soil and, accordingly, plants. The air is not heated. It receives heat from the ground and therefore does not dry out. In such a climate, plants feel very comfortable.

The number of ultraviolet lamps for rooms is calculated according to a simplified scheme: for every 10 sq.m, 1 kW of heater power is required.

Since the use of electricity for heating is the most expensive way to heat up, this option cannot be classified as economical. But if you plan to grow berries or flowers year-round in home greenhouses, then this option should be considered as optimal.

To optimize costs, it is necessary to install temperature controllers and sensors and thereby automate heating. You may also need additional lighting and automated system glaze.

Gas heating of greenhouses

In terms of arrangement, this is the most expensive project, but in terms of operation it is the cheapest. Can be used as boilers running on gas, so gas cylinders. For use gas equipment a special permit is required, and for its installation, the involvement of specialists.

In order to build a gas heating greenhouse with your own hands, it is attached to the house and communications are pulled from there. In general, the process is not complicated, since you only need to build up pipes and loop them in conjunction with the house. Separately, it is advisable to build a gas system for the greenhouse premises only if its premises exceed 100 sq.m and it is used for commercial purposes.

Solid fuel or mining stoves

Anyone can make stove heating in a greenhouse with their own hands. In fact, this is the most common stove - a stationary stone or mobile metal stove, through which the entire room is heated.

A wide variety of detailed drawings are available. step by step description how to build a do-it-yourself greenhouse with heating or how to equip an oven for heating a ready-made greenhouse. You can independently lay out the stove inside or in a separate vestibule, or purchase a wood-burning stove.

In addition, the market has a huge selection of modern solid fuel boilers for long burning. They remove the biggest inconvenience of using the stove - the frequent laying of firewood, coal, etc. Thus, everyone can make heating in the greenhouse on their own. Price solid fuel much cheaper than electricity.

Steam heating

Do-it-yourself steam heating of a greenhouse can be done in two ways: connect it to the heating of the house or make an independent system. This method can be considered an improved version of furnace heating. He has more high level efficiency and safety, but at the same time, higher maintenance costs.

The most effective ways of heating home greenhouses were listed above. Everyone chooses the most suitable option for him. We suggest opting for the latter method, which also has a lot of variations.

Steam heating

If you do not know how to make heating in a greenhouse with steam, then you need to heed the advice of specialists. They advise connecting the greenhouse to the heating system of the house only when it is located at a maximum distance of 10 meters from the house. Otherwise, such a connection is not economically viable and it is better to dwell on the option of installing a boiler or stove. By the way, the most ordinary potbelly stove will cope with the task of heating by 100%. It is easy to maintain, easy to clean and refill.

Steam heating schemes:

If a plot near the house was chosen as a greenhouse for connection to a common heating system, then two requirements must be met:

• the power of the boiler should be enough to heat both the house and the greenhouse;
• the pipeline running along the street should be reliably insulated.

Regardless of where the boiler will be installed, as well as what type it will be, home-made heating in the greenhouse is built according to the same scheme. In addition to the boiler, you will need to purchase the following equipment:

• radiators;
• pipes;
• circulation pump;
• security group;
• expansion tank;
• balancing valve;
• coarse filter.

To ensure heat, it is very important to correctly determine the number of radiators. If the height of the greenhouse does not exceed 3 m, then you can use a simplified calculation algorithm: multiply the area of ​​\u200b\u200bthe greenhouse by 120, and then divide by the heat output of one section of the radiator according to the data sheet.

Steam heating connection algorithm

Consider step by step algorithm equipment mounting:

1. We install the boiler on a previously prepared concrete foundation. If you opted for a solid fuel boiler, then it is better to build a special vestibule for it - so you will not open the greenhouse with each load of fuel.

1. We connect the boiler to the chimney. A more preferred option is a vertical stainless steel sandwich chimney that leads outside through a roof or wall. First, it is very easy to install. Secondly, it has a reliable design.
2. Pipes connect radiators. Optimum pipe diameter: 20-25 mm. Radiators must be selected as low as possible. If after replacing the heating system in an apartment or house you still have old radiators and pipes, then use them. So, you will significantly reduce the cost of arranging a greenhouse. An air valve should be installed on each radiator - a Mayevsky tap, as well as a valve that allows you to shut off the flow of water.
3. We connect the safety group immediately after leaving the boiler (the place of maximum temperature and pressure). It is a steel manifold, on which a pressure gauge, an air vent and a safety valve are placed. The collector is equipped with a coupling with which it is attached to the pipe.
4. We mount the expansion tank from below through the valve. It is installed in the area from the outlet of the boiler to the circulation pump.
5. We install a circulation pump to maintain a stable pressure in the system. It is mounted on the return pipe before entering the boiler. Before it, be sure to install a coarse filter.

So, the system is assembled, you need to press it with air to identify possible installation defects. To do this, connect a special compressor. First, with a sponge, soap all the joints. Then close the valves and taps. The compressor supplies the pressure specified in the technical passport of the boiler and radiators. Carefully inspect the joints - they should not have soap bubbles. If all is well, then you can fill the system with water to test the boiler.

Heating alternative

Not everyone uses greenhouses for year-round cultivation of greens, vegetables and fruits. For personal needs, planting starts mainly in mid-February and ends in October. In this case, it is irrational to install a separate heating system, as well as to use powerful electrical systems. As an alternative, warm beds or infrared floor heating can be offered.

Warm beds

It is a combination of certain materials that release heat when interacting. To create warm beds, they dig a ditch 70-80 cm deep, where the following components are laid:

• large branches for aeration;
• straw, hay, dry grass

It is better not to use cut tops from the beds, as it may contain pathogenic flora - insect larvae, viruses, etc.

• manure;
• peat;
• sod land.

All this is laid in layers and after 2 weeks you can start planting. Manure and straw begin to rot, while releasing a fairly large amount of heat. This is enough to warm the root system, thereby creating comfortable conditions for the plant.

infrared floors

This is a kind of electric heating system, but compared to UV lamps, it is not as wasteful. Due to the large heat-releasing surface, heating occurs faster. Structurally, this is a thin film that is rolled out on the surface, fixed and launched. You can use infrared floors directly for heating beds, as well as place them on walls or between rows.

VIDEO: How to make greenhouse heating with your own hands

If you decide to build a stationary greenhouse for year-round growing vegetables, then in any case, you need to solve the issue of heating it in winter and during the transition period. There are many different ways to organize greenhouse heating, and most of them can be done by hand. In the article we will consider these methods, as well as give recommendations on calculating the power of the heating system and choosing a source of thermal energy.

Types of greenhouse heating

There are really a lot of options for heating such structures, no less than for private houses. This is easy to verify if you study the projects for heating farm greenhouses of various sizes, posted on various Internet resources.

According to the method of transferring heat into the building, the heating system is of the following types:

• air;
• water;
• combined with direct heating of the soil.

For reference. In large farm greenhouses, infrared heating is often used with gas or electric heaters.

In the first case, one or more heat sources directly heat the air in the building, which is easier and cheaper to implement. It is more difficult to make water heating in a greenhouse with your own hands, but the effect will be greater, since it makes it possible to heat the growth zones of vegetables, and not the entire volume of the building. The optimal solution is a combined one, when the planting soil and the air in the greenhouse building are heated separately.

When choosing a heating method, the question inevitably arises, what is the best way to heat a building, what energy carrier should be used for this purpose? There are several options here:

• natural or liquefied gas;
• electricity;
• various types of solid fuel (wood, coal).

The choice of energy carrier depends on the individual conditions in each case, so you will have to make it yourself. We will consider how it is possible to heat a winter greenhouse with one or another fuel and what system schemes are used for this. True, there are alternative sources of heat, such as solar collectors or geothermal systems. But the former are ineffective in winter, and the latter are incredibly expensive, so it makes no sense to take them into account.

Natural gas heating

This energy carrier is very convenient to use, although it will not work to conduct and connect it with your own hands, this should be done by a specialized company. If this point is not taken into account, and even the cost of gas for the population different countries CIS, then this is one of the best options for greenhouses. Using gas heating, you can organize air, water and infrared heating methods winter greenhouse.

A common practice is to install infrared gas heaters on the roof of the room. If the structure has a small width, then the units will be placed along the axis of the building in one row. It is important that all the beds fall within the coverage area of ​​the device in width (it is indicated in the operating instructions). When this cannot be achieved, gas appliances are placed in 2 or 3 rows.

The advantage of gas infrared heating in winter is the direct heating of the soil, and only then - the air in the greenhouse. The disadvantage is the need for a ventilation device to remove combustion products.

Another option is a gas boiler plus a greenhouse water heating system. It must be understood that in greenhouse facilities the main task is to provide plants with heat, and not to warm people. To do this, wiring is carried out from smooth pipes with a diameter of not more than 40 mm over the entire area. Moreover, their laying is carried out along each bed at a height of 20-30 cm from ground level. It is allowed to use the following types of wiring:

• the supply line is along one wall, the return line is near the other. They are interconnected by transverse pipes running between the beds;
• supply and return are laid along one wall. Each heating pipe runs along one bed, and returns past another;
• the pipe is laid with a snake over the entire area of ​​the greenhouse, forming a single heating circuit.

Advice. Shut-off valves must be installed on each branch so that the circuit can be turned off when the plants are already harvested.

Additionally, in order to warm the air inside the building, it is recommended to place several heaters near the walls. Usually these are do-it-yourself registers made of smooth pipes. As you already understood, it will take a lot of work to install such a system, but you will only spend money on a gas boiler and its connection. You can go the other way: arrange air heating of the greenhouse by installing several gas convectors.

Electric heating

If we talk about the device of water electric heating, then it is carried out in the same way as gas. Only the source of heat we now have is different - a heating element, electrode or induction boiler. No permits are required for its installation, and therefore the work can be done independently.

It is even easier to make infrared heating with hanging appliances, they do not require ventilation for their operation. They are placed in the same way as gas ones, by fixing to the roofing part.

There is a variant of combined heating of a winter greenhouse, when an electric heating cable or a heating film is laid in the ground. At the same time, the space inside the building is heated by air heaters (fan heaters) or self-made oil radiators. Here the choice is entirely yours, as long as there is enough electrical power supplied.

It is noteworthy that the electric heating of a winter greenhouse can be economical, despite the high tariffs. After all, the coldest time is the night, when the cost of electricity is minimal, you just need to use a multi-tariff meter. In addition, such systems are easily regulated and automated.

Use of solid fuel

Heating greenhouses with wood is the most common and cheapest way, although troublesome. Most often, it is implemented using home-made stoves - brick or metal, for example, such as Buleryan.

One or more stoves are installed in the center of the structure, and its chimney is first laid horizontally and only then turns and goes outside. The goal is to extract as much heat from the flue gases as possible, so that the horizontal section can reach a length of 10 m.

Advice. A horizontal pipe should be laid with a slope towards the furnace in order to facilitate the passage of combustion products and improve natural draft.

When it is planned to install a water heating system, a solid fuel boiler is installed in the greenhouse or outside it. The first option is more preferable, since all the heat will remain inside the building, while the second one is used for the heat supply of several greenhouse structures from one solid fuel boiler. It is important to take into account 2 points: to insulate the highways passing along the street, and not to install shutoff valves on pipe sections outside the greenhouse.

How to choose a boiler for a greenhouse

Regardless of whether you decide to heat the building with wood or electricity, you must first find out the amount of heat needed for it. Here you can not do without calculation, and in order to complete it, you need to know the exact area of ​​\u200b\u200bthe floor and the translucent part of the greenhouse. In addition, you need to find data on the lowest daily temperature for your area, as well as the average wind speed during that day. This information is specified in the standard called "Construction climatology and geophysics".

On the nomogram shown above, we find the graph corresponding to the lowest temperature. Then, from the abscissa axis (wind speed), we draw a line until we meet this graph and determine the specific heat loss in relation to the fencing coefficient along the ordinate axis. It is easier to show the calculation using an example for a greenhouse with a floor area of ​​700 m2, glazing - 980 m2. Then, with a wind of 4.7 m/s and a temperature of -30 °C, according to the graph, the value of Q/k is 388 W/m2.

Now we need to find the fencing coefficient k, it is equal to the ratio of the area of ​​translucent structures to the area of ​​the floor. In our example, k = 980/700 = 1.4, then Q = 388k = 388 x 1.4 = 543 W/m2. It remains only to find out the total heat loss by multiplying the specific (543 W / m2) by the area of ​​the polycarbonate greenhouse (700 m2): 700 x 543 \u003d 380,000 W or 380 kW.

To select a boiler for a greenhouse, you need to multiply the heat loss value by the safety factor. Whatever heat source you take - solid fuel or gas, it cannot work at maximum all the time. For those greenhouses that are built of polycarbonate or using glass, the safety factor will be 1.3, and those covered with ordinary film - at least 1.5.

Advice. It is always better to choose a solid fuel boiler for long burning with a one and a half power reserve and large firebox sizes. This will save you from frequent loadings of firewood or coal in the middle of the night.

Conclusion

The organization of heating a winter greenhouse is a simpler event than a heating device for a residential building. Here, almost all the work can be done independently, if you have the appropriate skills. The main thing is to choose a suitable heat source and energy carrier. Finally - the traditional advice on energy saving: in greenhouses it is very important to insulate the floors under the beds, which will provide significant savings. For this purpose, foam plastic with a thickness of at least 100 mm is well suited.

In absolutely every part of our country, it is necessary to heat the house in cold weather. Every sane resident wants to figure out how to improve the heating complex of the dacha. Everyone knows that fuel for heating is constantly becoming more expensive. It is difficult to imagine the existence of a person living in Russian Federation without the heating complex of the cottage. The www portal contains a large number of various home heating complexes that use completely different principles for obtaining heating. Any heating system can be installed independently or hybridly.

Undoubtedly, it is very pleasant to see fresh greens and vegetables grown by oneself in one's own greenhouse on one's table at any time of the year. It is thanks to the home greenhouse that we can constantly receive the vitamins so necessary for our body. Properly designed and equipped systems and communications will be able to provide an optimal microclimate in the greenhouse all year round and its uninterrupted functioning. Heating a greenhouse is one of the most important tasks, which directly affects the profitability and efficiency of growing greenhouse vegetables. To solve this problem, you can turn to specialists for help, but it will be much more economical for the family budget if you decide to do the heating of the greenhouse with your own hands.

Varieties of heating systems

To begin, let's take a look at existing types heating systems:

• oven (outdated, so we will not consider further);
• gas;
• water;
• electrical;
• infrared or air.

Gas

This heating system is based on the use of gas burners, to which pipelines with natural gas are supplied. Air heating occurs as a result of gas combustion and spreads throughout the greenhouse (through the laid duct system). Gas heating has serious disadvantages:

• significant costs for the installation of gas supply lines;
• additional costs for the installation of forced ventilation;
• high fire hazard;
• significant dry air.

Water

Water heating is the most common heating method. To create this system, you will need: a boiler (boiler), a water main and heating appliances. Creating a water heating system is not so simple. You will need:

• calculate in detail the required boiler power;
• choose an energy carrier that should be suitable for operational characteristics;
• think about how to organize the thermal insulation of the greenhouse.

With such a heating system, water (coolant) will be heated in the boiler to the desired temperature and then circulate through the laid pipeline, while giving off its heat to the air of the greenhouse. The cooled water must be fed back to the boiler using a pump. The circulation of water will be repeated several times until the air in the greenhouse reaches the desired temperature. As a rule, such heating systems have three heating circuits (to ensure efficient heating of the greenhouse). One of them is laid on the ground, the second - in the middle of the walls, the third is placed under the ceiling.

Note! The main disadvantage of water heating is low efficiency (due to the high energy consumption for heating water). But there is also a more economical way of water heating - this is a connection to a centralized heating system.

Electrical

This method of heating involves heating greenhouses with standard heating devices. It is very expensive and dangerous! Your costs will be high, and the result will be minimal. In addition, as with gas heating, electric requires ventilation to distribute heat throughout the greenhouse.

infrared

This heating system is the most progressive, fundamentally new way of heating greenhouses.

Note! An important advantage of infrared heating is that it is analogous to the sun: the required temperature inside the greenhouse is maintained using infrared heaters, the peculiarity of which is that they heat plants remotely, while the air does not heat up and does not dry out.

• minimal cost ( low cost device and self-installation in just a few minutes);
• complete safety for the greenhouse, plants, human health;
• increasing the germination of seedlings and increasing the yield of the greenhouse.

We examined the most common methods of heating greenhouses. Whichever one you choose, don't forget to performance characteristics your greenhouse. It must be constructed from a strong, rot- and corrosion-resistant frame and a transparent coating that can optimally retain heat. When purchasing a finished greenhouse or materials for it self-manufacturing, always be guided by the criteria of quality, reliability, strength and durability.

early harvest is collected from its greenhouse primarily due to its heating - after all, solar radiation for most plants is sufficient only in the summer months. But keeping a winter garden or growing fresh vegetables and exotic fruits in severe frosts is impossible without specially equipped heating in a greenhouse, because the lowest temperature that can only be in a greenhouse is + 18 ° C. And only warm impenetrable walls are indispensable here. The most budgetary option for heating a greenhouse - if under summer cottage heating line passes. Then it remains to find the right place, and the problem of how to make heating in the greenhouse is solved. In all other cases, heating greenhouses will be more difficult, but it is quite possible to do it yourself - the diagrams and tips in this article will be extremely useful for this.

Option #1 - solar panels

It is possible to heat the greenhouse with the help of solar heat accumulators. First, they dig a 15 cm hole in the greenhouse and cover the ground with a layer of heat insulator, possibly polystyrene. A layer of polyethylene film is placed on top for waterproofing.

Then coarse-grained wet sand is placed on top and all this is covered with dug earth. This simple device makes it possible to maintain a satisfactory temperature in the greenhouse due to the accumulated energy of the sun, even at a temperature of - 10 ° C.

Option #2 - air heating

The easiest way to heat a greenhouse or greenhouse is to equip primitive air heating:

• Step 1. A piece of steel pipe is taken with a diameter of 50-60 cm and a length of about 2-2.5 m.
• Step 2. One end of such a pipe must be inserted into a film greenhouse or a greenhouse, under the other, a fire should be made.
• Step 3. The fire now needs to be constantly maintained. The air will quickly heat up in the pipe, pass into the greenhouse and give off heat to the grown plants.

This method of building heating is really easy, but somewhat inconvenient due to the fact that the fire must be constantly maintained.

Option # 3 - heating with gas

The main advantage of gas is that it is more stable in terms of supply, but the final cost of products from the greenhouse can surprise. Therefore, if heating a greenhouse in winter with gas lasts only a few weeks, then it is not necessary to pull it from a residential building and purchase expensive pipes for this. It will be enough to take a couple of cylinders for this purpose - they will last for a long time.

It is only important to remember that an excess of carbon dioxide can adversely affect the condition of plants, and therefore such a greenhouse must be well ventilated. And to remove combustion waste, it is necessary to use an exhaust device so that a constant supply of oxygen to the greenhouse is ensured. And so that the lack of oxygen does not lead to the cessation of the combustion process and the release of gas into the air, it is advisable to use heating devices with an automatic protective device - the sensors will immediately work as soon as the gas supply to the burner stops.

Option # 4 - stove heating

To begin with, we want to present you a video from a real homemade, who very simply and effectively solved the problem of heating his greenhouse:

Unlike electric heating, classic stove heating is not so burdensome in terms of financial plan. So, you can build a simple greenhouse stove with a hog or a horizontal chimney with your own hands and at no special cost. Its device principle is quite simple:

• Step 1. A brick firebox is laid out in the vestibule of the greenhouse.
• Step 2. A chimney is laid out along the entire length of the greenhouse, either under the beds or under the racks.
• Step 3. This chimney is removed from the greenhouse on the other side so that carbon monoxide leaves, and all the heat remains inside the building. As a result, the distance between the end wall of the greenhouse and the firebox itself should be at least 25 cm, but from the garden bed or rack with plants to the top of the hog - from 15 cm.

Or in this way:

• Step 1. You need to take a large barrel, with a capacity of about 3 cubes, and paint it from the inside in 2 layers so that it does not rust.
• Step 2. Holes are made inside the barrel for a chimney, a stove, an expansion barrel on top and a drain valve on the bottom.
• Step 3. The stove is boiled and inserted into the barrel.
• Step 4. A chimney is removed from the barrel, and a pipe 5 meters high is placed on the street.
• Step 5. A home-made expansion tank of 20 liters is installed on top of the barrel, which is pre-cooked from simple sheet iron.
• Step 6. Heating is cooked from a profile pipe 40x20x1.5, and the pipes are laid out on the ground at a distance of 1.2 m. So they must be laid out so that the soil near the roots of the plants warms up well.
• Step 7. To circulate water in such a home-made heating system, a special, but inexpensive pump is purchased.

You can heat such a stove with any wood, and the drain valve at the bottom of the barrel can be used not only to drain water, but also for drip irrigation when the water itself has cooled. To control the temperature in such a greenhouse, you can install an electronic temperature sensor inside it, and the digital display itself can be installed right in the house.

Option #5 - water heating

At the entrance to the radiators, it is advisable to equip the pipes with ball valves or thermal valves in order to regulate the temperature in different parts of your huge greenhouse for specific plants.

Boiler and chimney

A do-it-yourself greenhouse with heating is not only hanging radiators and piping, but also installing a boiler with a chimney.

The heating boiler can be placed both inside the greenhouse itself and placed in the heated room itself, which will further increase the efficiency of the entire system. Heat transfer from the boiler to the surrounding space will be unambiguous, so the air temperature in the greenhouse will increase.

But in the first option, you can not go inside the greenhouse at all while loading the boiler with fuel. The second option not only increases productivity and efficiency, but also saves a lot of space.

Convenient boiler - convenient operation

The water heated in the boiler is supplied by a pump to the pipes laid along the walls of the greenhouse. They are made from a variety of materials, but the most commonly used are copper, plastic and steel. For greenhouses, the second option is more suitable, because plastic pipes are cheap, light and not prone to rust. This is especially true for soil heating.

Water heating installation

1. Take a piece of steel tube with a diameter of 500-600 millimeters and a length of about 2-2.5 meters.
2. Then one end of it should be introduced into a film greenhouse or greenhouse, and a fire should be built under the other edge. Its combustion should be constantly maintained. This is why this method of heating is inconvenient.
3. Due to the fire, the air in the pipe quickly heats up and passes into the greenhouse. Heat will be given to the plants that grow in it. This is very easy way heating.

Heating a greenhouse with wood

This is one of the budget options. For this purpose, stoves such as the Bullerjan are suitable, which eliminate the need to lay firewood at night. Of the advantages of such heating, the following should be noted:

1. The room heats up quickly.
2. The temperature is maintained at the desired level for a long time.
3. Fuel economy.

Solar batteries

Solar panels can be used to heat the greenhouse. The device process is as follows:

1. First, a hole is dug in the greenhouse with a depth of 130-140 millimeters.
2. It is covered on top with a layer of heat insulator (for example, polystyrene).
3. Then you need to lay out coarse-grained wet sand on top.
4. After that, all this is covered with dug earth.

Thanks to this method of heating, solar energy is accumulated and maintains a normal temperature in the greenhouse for a long time.

Heating a greenhouse with gas

Gas heating has one significant advantage - it is more stable in terms of supply. The arrangement of this type of heating should be approached depending on current needs. So, if in winter the greenhouse needs to be heated for only a few weeks, then cylinders can be used, rather than expensive pipelines. Only then the room should be well ventilated. After all, plants do not tolerate excess hydrocarbons in the air.

In order to eliminate combustion waste, you can put a special exhaust device. As a result, oxygen will be supplied to required quantities to ensure a complete combustion process. In addition, due to the presence of a hood, the gas will not be released into the air. For safety reasons, it is recommended to use heaters equipped with automatic protection, which will immediately work when the gas supply to the burner stops.

Stove heating

Furnace heating does not require as much expenses as electric heating. A simple greenhouse stove can be completely built independently. Moreover, it does not require large financial investments. Consider the principle of the device of one of the options for the furnace:

1. The vestibule of the greenhouse is lined with bricks. In this case, the chimney is laid along the entire length of the room (including under the beds and racks). It heats the greenhouse, and carbon monoxide comes out from the outside on the other side.
2. The stove should not stand close to the end of the greenhouse. It is recommended that the distance between them be at least 250-270 millimeters. From the bed to the top of the hog should be at least 150 millimeters.

There are other options for installing stove heating in a greenhouse. Let's talk about one of them:

1. A barrel with a capacity of about 3 cubic meters is taken. To prevent it from rusting, we paint it inside in two layers.
2. Then holes are made inside it for the chimney and stove.
3. After that, the stove is welded and inserted into the prepared barrel. Holes are cut at the top for the expansion barrel and at the bottom for the drain cock.
4. Now the chimney is removed from the tank. From the outside of the greenhouse, a pipe 6 meters high is placed on it.
5. Then, an expansion tank welded from a sheet of iron with a capacity of 20 liters is installed on top of the barrel.
6. After is taken profile pipe 40x20x1.5, heating is welded from it. In order for the soil near the roots to warm up well enough, the pipes are laid out on the ground with a distance between them of about 1-1.3 meters.
7. The water in the system must circulate. To do this, you need to purchase a pump. Any wood can be used as fuel.
8. The drain cock at the bottom of the tank can be used both for drip irrigation and for draining water. Climatic conditions and temperature in this case are controlled remotely using electronic sensors installed in the greenhouse. The very same temperature value is visible on the digital display, which is convenient to install at home.

Combined heating

This method has become quite widespread. It allows you to respond very quickly to changes in operating conditions. So, for example, when the electricity is turned off, the heating method changes to another.

The heating of the greenhouse allows it to be used for growing various crops throughout the year. This makes it possible to get up to three harvests per year and grow a variety of heat-loving exotic plants, creating optimal conditions for their development.

Greenhouses can be heated in different ways. Each option has a number of important features and benefits. Read information about the most popular heating methods, learn tips for choosing the best option and get to work.

Comparative characteristics fuel cost

What to consider when choosing a heating system?

When choosing a heating system, it is necessary to pay attention to the overall dimensions of the room and its type, because. For different materials the required intensity of heating will also vary. For example, polyethylene is characterized by high heat loss, so this material will require more intensive heating compared to a polycarbonate greenhouse.

When arranging the heating of a greenhouse, consider the size of the total cost of installing the system and its maintenance. Some heating options require serious financial investments, and their use in small greenhouses will be impractical. Others are simple and inexpensive to set up, but consume a lot of fuel in the process.

Otherwise, the owner must decide for himself how beneficial it will be to use one or another heating option specifically for his situation. The main thing is that the system provides, does not dry out the air and creates optimal conditions for the development of cultivated crops.

Greenhouse heating options

Familiarize yourself with the main features of the systems most commonly used to heat greenhouses.

This option should be considered if it is possible to connect the heating of the greenhouse to the heating system of the house.

Laid from the house to the greenhouse, they need high-quality insulation. The power reserve of the boiler must be sufficient to provide the required level of heating for both the house itself and the greenhouse.

If the length of the pipeline between the house and the greenhouse exceeds 10 m, it is better to refuse to use such a system.

There is also a way to organize autonomous steam heating. In this case, the boiler is installed in the greenhouse. Pipes and batteries are connected to the heating unit, the coolant is supplied. Water is traditionally used as a heat carrier.

To ensure forced circulation of water, the system, as a rule, is equipped with appropriate pumping equipment.

For organization, air heated in the furnace of a special boiler is used. Such heating is characterized by minimal cash costs for fuel and high rates of heat output.

In about half an hour after starting the equipment, the air temperature in the greenhouse can rise by 20 degrees. An additional advantage of the system is the absence of the need to use any intermediate heat carriers.

Air heating is best suited for regions with a mild climate. In more severe conditions, it is recommended to use a complex of air and steam heating.

In such a system, heat is generated by the combustion of gas. It is possible to equip the system both by connecting to a stationary gas supply, and by using fuel in cylinders.

During the operation of the system, there is an intensive intake of air from the heated room, accompanied by the release of water, carbon dioxide and other wastes that are dangerous for humans and, of course, plants. In view of this, the arrangement will entail additional costs for the organization of the ventilation system.

Such heating is well suited for small greenhouses. However, when used over large areas, the cost and complexity of maintenance can be prohibitive.

Modern electric heating units allow you to equip the efficient heating of the greenhouse without much effort.

Among the main advantages of such devices, it should be noted that in the process of their work only heating of plants and soil occurs. The air does not warm up. It gradually receives heat from the heated earth. This allows you to equip the most efficient and economical heating system.

Modern systems equipped with sensors and temperature controllers, which gives ample opportunities for dividing the greenhouse into different thermal zones and providing the most comfortable conditions for each group of plants.

Prices for popular models of infrared heaters

The main unit in such a heating system is a solid fuel boiler, which, as a rule, works on wood or coal.

The simplest furnace heating system includes a solid fuel boiler and a chimney that goes from the greenhouse to the street. Additionally, you can complete the system with pipes and radiators, which will allow you to organize the most efficient and high-quality heating.

The chimney needs regular cleaning from fuel combustion products.

Both conventional wood-burning stoves and modern ones are available on the market. Such devices do not need frequent filling of fuel and consume it as efficiently as possible.

Installing a solid fuel boiler directly in the greenhouse will cause the air and soil to dry out, as a result of which the plantations grown may simply die. To prevent this from happening, when installing a solid fuel boiler in a greenhouse, it is imperative to equip an air humidification system. Usually it is enough to install a large container of water.

Stove greenhouse heating is the most popular heating option. In addition, there is nothing complicated in arranging such a system - even a novice master will cope with the work. Also, solid fuel heating unconditionally outperforms electric heating in terms of cost. That is why the procedure for organizing heating of a greenhouse will be considered using the example of stove heating.

Arrangement of furnace heating of the greenhouse

First option

First step. In the vestibule of the greenhouse, lay out the brick furnace of the stove on a pre-equipped foundation.

Second phase. Lay out along the entire length of the room.

Third stage. Lead the flue pipe out of the greenhouse from the other side. As a result, the products of combustion will be effectively removed from the room, and the heat will remain inside.

Refractory brick

Second option

1 - heating boiler;
2 - tank-thermos;
3 - circulation pump;
4 - relay-regulator;
5 - registers;
6 - thermocouple

First step. Prepare a large metal barrel. Paint its inner surface in two layers - this will provide protection against corrosion.

Second step. Make several holes in the body. To one of them you will connect the chimney. Others will be used to connect the tap and expansion tank.

Third step. Weld the oven sheet metal and insert it into the prepared barrel.

Fourth step. Weld a piece of pipe to the hole in the barrel to connect the chimney. The total length of the smoke exhaust structure should be at least 4-5 m.

Fifth step. Install the expansion tank on the barrel. A capacity of 20-30 liters will suffice. You can buy a tank or weld it yourself from sheet metal.

Sixth step. Run piping around the greenhouse. Lay the pipes on the ground with a step of 120 cm. This arrangement of the heating elements will contribute to the effective heating of the soil in the places where plant roots are located.

Seventh stage. Install to force water circulation through the system.

Turn on the water supply and make sure all connections are tight. If leaks are found, seal them immediately. Only after that you can start testing the stove and take the heating system into permanent operation.

Successful work!

Boiler for a greenhouse from a gas cylinder

To work, you will need an empty gas cylinder directly, a coil (a U-shaped tube with threads at the ends), a metal grill, a gate valve, hinges and two metal door handles. You should also prepare a chimney pipe, taking into account the length of the greenhouse, a welding machine with electrodes, a drill and a grinder, pipes and a radiator for the heating circuit. For the front wall of the furnace, a small sheet of steel is required.

From these simple devices, a boiler with a water circuit is assembled to heat the country greenhouse.

Step 1

After making sure that the balloon is empty, we saw it with a grinder in two. One of the parts will serve as the body of the furnace, from the second we will make an ash box.

Step 2

We take the grate, make measurements and cut it so that the resulting segment fits inside the cylinder. We grab the grate by welding. Now the stove is divided into a fuel combustion chamber (2/3 of the volume) and an ash pan (1/3 of the volume).

Step 3

We put the cylinder on a sheet of steel, circle it with chalk, cut out the front wall according to the markings. Cut off 1/3 of the circle. From this piece we make the ash pan door by welding the handle and cutting out a semicircular piece for the bottom of the drawer from the second part of the cylinder.

We cut a rectangular hole in a larger piece of the wall. We weld hinges, a handle and a latch (latch) to the cut out rectangle. The door should tightly close the firebox.

Step 4

We introduce a coil (water circuit) inside the furnace. We make markings for the coil, drill two holes in the upper part of the furnace to bring out the ends of the threaded pipe. We weld the coil to the metal plate and the top of the furnace.

Trying on the coil

Step 5

We equip the chimney. We cut a hole for the pipe in the upper back of the furnace. We weld a pipe to connect the chimney. We monitor the quality, otherwise the draft and operation of the boiler will be impaired.

We weld the chimney pipe in such a way that it will pass at an inclination of about 20 degrees through the entire greenhouse. The chimney will exit through the back wall of the greenhouse, rising 1 meter above the roof. Be sure to consider thermal insulation at the point of contact between the greenhouse wall and the chimney, so that a fire does not happen.

We connect the chimney pipe to the furnace pipe using sheet asbestos and a coupling, tightening it with wire.

Step 6

We connect metal pipes for the water circuit to the ends of the coil that are brought out. The piping must contain an expansion tank and a pump that will pump water through the pipes.

Thus, the water heated in the coil will flow into the radiator, and when it cools down, it will again fall into the boiler. The chimney pipe will serve additional source heat. Also, a long chimney will reduce heat loss, increasing the efficiency of the boiler.

Step 7

We install the stove in the greenhouse, having previously built a brick or concrete base and laid out a brick screen on three sides of the firebox. For stability, the furnace can be equipped with legs made of any fittings or long products.

We load fuel into the stove, ignite it, adjust the draft by opening or closing the firebox / ash pan door.
