The early crop is harvested from their greenhouse primarily due to its heating - after all, solar radiation is sufficient for most plants 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 hotbed 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 important to remember that excess 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

Unlike electric heating, classical stove heating not so burdensome financial terms. 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 brought out of the greenhouse on the other side to leave carbon monoxide, and all the heat remained 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. From profile pipe 40x20x1.5 heating is brewed, and the pipes are laid out on the ground at a distance of 1.2 m. It is necessary to lay them 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

Water heating for a greenhouse is one of the most profitable in material terms. And you can make a water electric heater with your own hands.

Method # 1 - a thermos from an old fire extinguisher

So, you will need the body of an old, already unnecessary fire extinguisher, the top of which will be cut off. Work order:

• Step 1. At the bottom of the case, you need to mount a heating element with a power of 1 kW, which can be taken from an electric samovar.
• Step 2. In order to be able to pour water into the electric heater, a removable cover is made on top.
• Step 3. Two water pipes must be attached to the body, which are connected to the radiator. It is necessary to fasten the pipes with rubber sealing gaskets and nuts.

In order for the heater to be automated, it is better to use such a circuit - with an AC relay, such as MKU-48 with a voltage of 220 V. As soon as the temperature sensor works, it will close contacts K1. The heater will begin to heat the water, and it will raise the temperature in the greenhouse. As soon as the water reaches the set level, the temperature sensor will immediately work and the power circuit of relay K1 will break, and the water heater itself will turn off. If the MKU-48 relay cannot be found, you can use the second circuit, where the relay has contacts that do not pass current less than 5A.

Method # 2 - heating element + old pipes

In this case, a small amount of old pipes, heating elements and an electric welding machine will be used. Everything will be made quickly and reliably.

So, in a convenient corner of the greenhouse, you need to install a boiler with a volume of about 50 liters and with an electric heater of 2 kilowatts. When heated, the water will rise into the expansion tank along the riser, and will be supplied to the heating system located around the entire perimeter. The system itself should be with a slight downward slope of the pipes.

Step 1. The boiler will need to be made from a piece of large diameter pipe, to which the bottom with a flange will be welded.

Step 2. The heating elements must be connected with a power cord to the plug and securely insulated.

Step 3. All joints between the flange and the body must be well sealed with a rubber gasket.

Step 4. An expansion tank with a volume of up to 30 liters is made from pipe scraps. Couplings are welded from below and from both ends for connection with the boiler riser and with the system.

Step 5. A lid for topping up water is cut out in the tank itself, because its level will need to be constantly monitored.

Step 6 A pipeline is made from metal pipes, at the ends of which it is necessary to make a thread in advance for a convenient connection.

Step 7. Now the boiler body must be grounded with a flexible three-core copper wire, which is rated for voltage from 500 V and without insulation. Both cores must be attached to the phases of the heating element, and the third core to the boiler body. By the way, for the period of cold weather it will be possible to use special screens made of foil or other heat-reflecting material.

The main thing is that during any installation of the heating system of a greenhouse or hotbed, observe all safety rules and strictly follow the instructions.

Method # 3 - installing a solid fuel boiler

The boiler itself can be located both in the greenhouse room and in a separate room. The advantage of the second option is that you can put firewood or fuel into the boiler without going into the greenhouse, and now it will not take up valuable space, like the fuel itself. And the downside is that the boiler also produces some heat energy, which would not be an extra greenhouse.

You need to put fuel into the heat generator 2 times a day - and that's it. And at the same time, such a boiler is absolutely fireproof, and therefore it can be safely left overnight without any control. In addition, fuel consumption is quite small.

Greenhouses are used to grow and harvest heat-loving crops. all year round. Such structures can be of various sizes: from small country houses to large industrial ones. In each individual case, different equipment for heating greenhouses can be used. So, if for the equipment of industrial facilities are hired special organizations, which are engaged in the delivery and installation of heating systems, then small private greenhouses can be equipped with your own hands. How to do this, we will tell further.

Heating using solar batteries

The easiest and cheapest way to heat a greenhouse is to use solar energy. To use it, you need to install a greenhouse in a place that receives enough sunlight during the day. The material from which the structure is made is also important. For the use of solar heating greenhouses, polycarbonate materials are used. It helps to create an excellent greenhouse effect because it has a cellular structure. Each of its cells stores air, which works on the principle of an insulator.

Another good material, from which it is better to make a greenhouse if you plan to heat it with sunlight - this is glass. 95% of sunlight passes through it. To collect maximum amount heat, build an arched greenhouse. At the same time, it should stand along the east-west line, especially if you plan to install the winter version of the structure.

In addition, a so-called solar battery is installed around it. For this, a trench is dug 40 cm deep and 30 cm wide. After that, a heater (usually expanded polystyrene) creeps to the bottom, it is covered with coarse sand, and covered with plastic wrap and earth on top.

Did you know? As a heat-insulating material, it is best to use extruded polystyrene foam. It is not afraid of moisture, does not deform, has a high level of strength and perfectly retains heat.

This design, at night, allows you to save the heat that has accumulated in the greenhouse during the day. The disadvantage of this method is that it can only be used during periods of high solar activity, and in winter it will not give the desired effect.

Another long-standing method of heating a greenhouse is the use of biological materials. The principle of heating is simple: during decomposition, biological materials release a large amount of energy, which is used for heating. Most often, horse manure is used for this purpose, which can warm up to a temperature of 70 ° C within a week and keep it for at least four months. To lower the temperature readings, it is enough to add a little straw to the manure, but if cow or pig manure is used, then no straw is added to it. By the way, the straw itself can also be used as a material for bioheating.

What else can be used to heat the greenhouse with this method of heating? Sawdust, bark and even household waste. It is clear that they will give much less heat than manure. Although, if you use household waste, which is 40% paper and rags, then it may well reach the performance of "horse" fuel. True, it will take a long time to wait.

Did you know? Experienced gardeners use the so-called artificial manure. They lay in layers straw, cut to about 5 cm (10 kg), lime-ammonium nitrate (2 kg), superphosphate (0.3 kg). The layer of compost earth, at the same time, should be up to 20 cm, biofuel - up to 25 cm.

Also, you can take care of vegetable humus in advance, which is also perfect for the role of biological fuel. To do this, freshly cut grass is folded into a box or barrel and filled with nitrogen fertilizer, for example, a 5% urea solution. The mixture must be closed with a lid, pressed with a load, and after two weeks the biofuel is ready for use.

Important! Biological heating has a positive effect on the microclimate of the greenhouse. It saturates the air with microelements, carbon dioxide, while maintaining the necessary humidity, which cannot be said about technical methods of heating.

Biofuels are used in the following way. The entire mass is laid to a depth of approximately 20 cm, while the total laying thickness should be approximately 25 cm. Further, nature itself conducts everything necessary processes. You only need to occasionally water the soil so that the decomposition processes take place actively. One such bookmark is enough for at least 10 days, maximum - for four months. It all depends on the type of biological materials used.

Installing a stove in a greenhouse

A good answer to the question "How to heat a greenhouse with high quality?" - installation of a metal or brick stove and a chimney pipe system around the entire perimeter of the greenhouse with access to the outside. Heat comes from both the stove itself and from the smoke that exits through the chimney. Any fuel material can be used. The main thing is that it burns well.

gas heating

Another popular way to heat greenhouses is to use heat from burning gas. True, heating a greenhouse with gas is considered a rather energy-intensive way. Its essence lies in the fact that infrared sensors are installed along the perimeter of the greenhouse. gas-burners or heaters. Gas is supplied to them through flexible hoses, which during combustion gives off a huge amount of heat. The advantage of this method is that the heat is evenly distributed throughout the room.

True, in this case, you need to take care of a good ventilation system. During combustion, a huge amount of oxygen is used, and if it is not enough, the gas will not burn, but accumulate in the greenhouse. To avoid this, gas heating greenhouses are equipped with an automatic protective device that regulates all ongoing processes.

Heating with electrical appliances

Due to the availability of electricity, this method has become one of the most popular among gardeners and farmers. Especially those who are engaged in greenhouses and in winter. Its main advantage is its availability all year round and the ability to easily adjust the temperature regime. Among the shortcomings, the high cost of installation and the purchase of the equipment itself are distinguished. To use the electric heating of the greenhouse, it is necessary to install a special heater. What it will be depends on the heating system that you prefer. Consider the most popular of them.

Convectors and infrared heaters

One of the safest and effective methods electric heating type. The essence of this method copies the method of solar heating of the greenhouse. Ceiling-mounted polycarbonate greenhouse infrared heaters heat plants and soil. The latter accumulates heat and returns it to the greenhouse. The advantage of this method is that such heaters are easy to install, reinstall for different needs, and also consume relatively little electricity. At the same time, they do not occupy the working area, since they are mounted on the ceiling.

Among other advantages, the absence of air movement is noted, since some plants are very sensitive to this. If you install heaters in a checkerboard pattern, you can warm up the greenhouse evenly. It is very easy to regulate the temperature.

Cable heating

Another heating method that does not take up any working space is cable heating. A heating cable, installed on the principle of underfloor heating in houses, heats the soil, which releases heat into the air. The main advantage of this method of heating is maintaining the desired soil temperature at different vegetative stages of plants, which positively affects the yield. The system is easy to install, the temperature regime is also easily regulated, and very little electricity is required.

Most often, such a heating system is used in the construction of industrial greenhouses. It is calculated during the design of the structure and is laid during its construction.

Installation of heat guns

One of the most simple ways heat the greenhouse without installing complex structures - put a heat gun inside. It can be used immediately after purchase by hanging it from the ceiling of the greenhouse. So hot air will not harm the plants. Another advantage is the presence of a fan. During operation of the unit, it distributes warm air throughout the greenhouse and does not allow it to accumulate under the ceiling.

There are many varieties of such guns: electric, diesel, gas. Which one to choose depends on the specifics of the greenhouse and the plants grown. For example, there are guns that can work in conditions of high humidity, with a lot of dust in the air and other difficult conditions.

Using an electric heater or hot water boiler

You can also heat greenhouses with the help of boilers that run on electricity or solar, wind energy. They have high efficiency - up to 98%. Do water heating greenhouses made of polycarbonate can also be installed from a stove by installing a water-heating boiler on the stove. A system of pipes should depart from it to the water intake tank-thermos. From it to the greenhouse, hot water will flow through the pipes. At the end of the system, the pipes fork, descending down the walls and returning to the boiler.

Thus, a constant circulation of hot water is maintained, which through the pipes gives off heat to the air. Depending on how the entire system will be laid and where the boiler will be installed, it is possible to warm up the air more or capture the soil of the greenhouse as well.

Did you know? For such heating, a central heating system can be used. It is used if the greenhouse itself is located no further than 10 m from your house. Otherwise, this method will be inefficient due to large heat losses during the transportation of water from the central system to the greenhouse. Remember that you must have the appropriate permission for such a solution.

This principle is based on the use of any heating boilers described above, to which a heat pump is connected. For example, when used together with a water boiler, the water in the pipes around the perimeter of the greenhouse can be heated up to 40°C. You can also connect it to other heating devices. As a rule, it turns on and off automatically, and therefore saves energy.

In addition, such a unit eliminates harmful emissions into the atmosphere, because the pump does not use open gas mixtures and other sources of fire. The unit itself takes up little space and looks neat. Another advantage of the pump is that it can be used not only for heating in winter, but also for cooling in summer.

The principle of operation of the device is quite simple. The unit is connected to the track or collector, where the heat will pass. A manifold is a long pipe through which liquid flows smoothly. Usually it is ethylene glycol, which absorbs and gives off heat well. The heat pump drives it along the perimeter of the pipes in the greenhouse, heating it up to 40 ° C, provided that the water boiler is running. If air is used as a heat source, it can be heated up to 55°C.

The most primitive, and therefore inefficient way of heating a greenhouse is air. It involves the installation of a pipe, one end of which goes into the greenhouse, and under the other, outside, a fire is made. The diameter of the pipe should be approximately 30 cm, and the length should be at least 3 m. Often the pipe is made longer, perforated and carried deep into the room in order to distribute heat more efficiently. The air that rises from the fire enters the greenhouse through a pipe, heating it.

Important! The fire in this case must be maintained constantly. Therefore, this method is used mainly as an emergency, in case of a breakdown of the main one.

The system is not very popular because it does not allow the soil to warm up well. Typically, pipes are installed under the ceiling so that the heat does not burn the leaves of plants. At the same time, it is necessary to constantly monitor the level of humidity, since with such heating it drops sharply and has a bad effect on plants.

Another way to heat the greenhouse with air is to install a fan that drives warm air. In this case, there is no need to install an extensive pipe system. The air heats up quickly, and the mobility of the fan and its lightness allow it to be used at various points in the greenhouse. In addition, the fan can be used not only for heating, but also for normal ventilation of the room, which is also necessary for the normal growth of plants.

A greenhouse is a great option for growing a variety of vegetables, as it creates unique climatic conditions that promote growth. In addition, the greenhouse allows you to get early harvest when the street is still not warm enough for the full-fledged cultivation of vegetables. However, in order to create optimal conditions in the spring, the greenhouse needs heating, which will ensure the temperature is not lower than 18 degrees Celsius.

insulated greenhouse

• Solar heating and batteries;
• Air heating;
• Heating with gas;
• Heating with a solid fuel boiler;
• Stove heating;
• Water heating;

So, now a little more about the organization of each type of heating.

solar heating

solar heating

Main components:

• Photoelectric generator;
• Control block;
• Conversion block;
• Accumulator battery;
• The heat-releasing element is the consumer.

The principle of operation is as follows.Solar radiation affects the photovoltaic generator, which, when exposed to sunlight, begins to emit electricity, coming through the control unit to the battery, where it is accumulated and transmitted through the conversion unit to the heating element in the greenhouse.

The best option for the design of a greenhouse for organizing this type of heating is an arched transparent.

It is important to ensure the tightness of the greenhouse structure in order to eliminate drafts.

The photovoltaic generator is placed in a place that is lit from early morning, it immediately starts working to heat the greenhouse. The heating element is placed under a layer of soil. The battery is designed to store energy in order to heat the greenhouse at night. This heating option will allow you to maintain the required temperature in the greenhouse, even if it drops to 5 degrees outside at night..

The main disadvantage of such a system is the high cost of components.

Air heating of greenhouses

To implement it, you need an ordinary steel pipe with an internal diameter of about 60 millimeters and 3 meters long. One of the ends of the pipe through a hole in the wall is placed in the space of the greenhouse, and the other end is brought out into the street. Under it, a small fire is bred, the warm air from which heats the pipe and the air in it.

This method is simple, but completely inconvenient for implementation, since it is not possible to constantly maintain a fire.

Gas heating

Gas heating of the greenhouse

This method of heating consists in the installation of a gas-fired heating device. It is also necessary to purchase 2 gas cylinders. When the gas is burned, the air in the greenhouse will heat up and provide optimal conditions for the growth of vegetables.

The main problem of this method of heating is the accumulation of excess carbon dioxide in the greenhouse, which negatively affects the growth of vegetables.. Therefore, when implementing this heating system ventilation is required, providing additional air flow to maintain combustion.

Installation of a solid fuel heating boiler

Alternatively, you can install a solid fuel boiler in the greenhouse or next to it.

solid fuel boiler for greenhouse

In this case, the following components will be needed to install the heating system:

• Boiler;
• Pipe system;
• Several radiators.

The advantage of this option is that it does not require a constant load of firewood. Modern solid fuel boilers allow you to maintain combustion from just 2 fuel loads per day. The disadvantage is the need for additional installation of pipelines and heating radiators.

Furnace heating of the greenhouse

Stove heating is implemented if the greenhouse area is more than 15 square meters.

There are two layout options.

Option 1

This is a simple option, you will need:

• An ordinary small heating stove of the "potbelly stove" type;
• Chimney pipe;
• Chimney;
• Chalk or lime.

The stove is installed on one side of the greenhouse, and the chimney passes through the greenhouse and ends with a chimney that leads the combustion products outside the greenhouse. As a result, the chimney pipe heats up and gives off heat to the air in the greenhouse.

In this case, it is important to monitor the tightness of the chimney pipe, since the ingress of smoke into the greenhouse room is unacceptable. To detect a smoke leak as soon as possible, it is necessary to paint the pipe with chalk or lime - on a white surface, places that let smoke through will be clearly visible.

To ensure good draft, it is necessary to install a chimney pipe with an overestimation to the chimney- about 1.5-2 centimeters per linear meter of pipe.

In order to fire safety it is necessary to ensure the distance from the chimney to the racks with vegetables at least 15 cm distance. It is also necessary to place the stove, chimney and chimney at a distance of at least 25-30 centimeters from the walls of the greenhouse.

Option 2

The second option for stove heating is to lay a piping system.

For its installation you will need:

• Large barrel;
• Stove;
• Expansion tank;
• Drain valve;
• Pipes of rectangular (40x20 mm) or round section (up to 30 mm);
• Chimney pipe;
• Circulation pump.

A large barrel plays the role of a housing for the heating system. It fits the stove, expansion tank. The chimney from the stove goes outside the greenhouse in the form of a vertical 5 meter pipe.

ventilation installation required

The expansion tank is welded to the walls of a large barrel-case above the stove, so that the heat from burning firewood goes to heat the water. Pipes are welded to the expansion tank, which are laid along the perimeter of the greenhouse at a distance of 1-1.5 meters. Since the arrangement of the pipes is horizontal, it is not possible to realize the natural circulation of the coolant, therefore a small circulation pump is connected to the pipeline system.

With water heating, an almost constant air temperature in the greenhouse is obtained.

For implementation this method you will need the following components:

• Old big fire extinguisher;
• Heating element;
• Temperature sensor;
• Pipe system.

3 holes are cut out in the fire extinguisher body: for a hot pipe, for a return pipe and for installing a heating element. A pipe is drawn from the upper hole, which is laid in the upper part of the greenhouse, and a pipe runs from the lower hole along the bottom of the greenhouse. It is important to weld the heater and pipes tightly to eliminate water leaks.

The heating element is connected to the mains, the water is heated, and its natural circulation through the pipes is ensured. An important element of the heating system is a temperature sensor, which is installed in the greenhouse and measures the air temperature. When a certain value is reached, it turns off the heating element. When the temperature drops, the heating element starts working again. The result is an almost constant air temperature in the greenhouse.

Outcome

As you can see, there are a lot of options for heating a greenhouse. However, you should not get lost in this variety - you need to determine the optimal and most profitable for yourself, and then proceed with the installation work.

Video on how to make energy-saving greenhouse heating with your own hands

In this video you will learn how to make greenhouse heating in winter by installing infrared panels

The heated greenhouse allows you to have fresh herbs 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 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.
