Heating Greenhouses With Your Own Hands: Detailed Instructions. Do-it-yourself greenhouse heating system: the best ways to warm greenhouses in winter Do-it-yourself heating in a greenhouse scheme

If you plan to use your greenhouses in winter period, consider solving the issue of organizing heating even before the first cold weather approaches. The easiest way to solve the problem is when a heating main is laid under the site. In such a situation, it remains only to choose a place to connect and install suitable batteries in the greenhouse.

In other cases, the problem of heating has to be solved on its own. There is nothing difficult in this. Plenty available various systems, so that you can organize the most efficient heating, best suited to your particular greenhouse, without any problems.

Before proceeding with the arrangement of any kind of heating, the greenhouse must be properly insulated.

First step. Dig a hole about 15 cm deep over the entire area of \u200b\u200bthe greenhouse, or at least in free places.

Second step. Cover the bottom of the pit with thermal insulation material. Usually foam boards are used.

Third step. Cover the insulation with a waterproofing film, polyethylene is usually used.

Fourth step. Fill the resulting "pie" with a small layer of sand, and then the earth dug at the very beginning.

Thanks to such a device, satisfactory conditions will be maintained in the greenhouse even at a temperature outside the window of -5-10 degrees. However, this solution cannot be considered as a full-fledged heating. This is elementary thermal insulation, which must be used in combination with other heating methods.

Small greenhouses can be heated with primitive air units. All necessary elements available at any summer cottage or sold at a hardware store for a penny.

First step. Buy or find an unwanted steel pipe on the farm. A product with a length of about 250 cm and a diameter of about 60 cm is suitable.

Second step. Insert the end of the pipe into the greenhouse room. The other end of the pipe must be brought outside. A fire is made under the "street" end of the pipe.

The outdoor air will be heated by the flame of a fire and get into the greenhouse through a pipe. Heating is really very simple in its organization, but you can’t call it convenient. First, for the system to work, you need to keep the fire burning. Secondly, it will not work to regulate the intensity of heating and the temperature in the greenhouse.

Heating with gas

Gas-based heating has many advantages. On the modern market a wide variety of units and devices are presented, with the help of which it is possible to organize the most efficient heating in accordance with the needs of a particular user. In addition, gas is one of the most cost-effective sources of energy.

If you plan to constantly heat your greenhouses with gas, you will have to buy a boiler and lay the necessary pipes. This will require a relatively large amount of money. Additionally, you will have to spend money on the installation of a high-quality ventilation system.

If there is no need for a full-fledged gas heating device, buy several cylinders of fuel and equip the heating system based on them.

Traditional stove heating is characterized by high efficiency and relatively simple arrangement. For example, you can without special financial investments build oven with a horizontal chimney.

First step. Lay out the firebox of the stove in the vestibule of your greenhouse. Performed traditional brickwork.

Second step. Lay a chimney under the beds or along the length of the greenhouse. It can also be laid under the racks.

Third step. Lead the chimney through the greenhouse wall. Consider the placement of the pipe so that it can effectively remove the products of combustion of the fuel, while passing over areas that need heating.

Place the stove in such a way that its firebox is at a distance of at least 25-30 cm from the end wall of the greenhouse.

You can also make a furnace from a metal barrel.

First step. Prepare a metal barrel with a volume of about 250 liters. Cover the inner walls of the container with two layers of paint so that the material does not rust.

Second step. Mark and cut holes for the stove, chimney, drain cock (installed at the bottom) and expansion tank (placed at the top).

Third step. Weld the stove (usually they make a rectangular structure of sheet steel in accordance with the dimensions of the barrel) and install it in a container.

Fourth step. Remove the chimney from the barrel. The length of the "street" part of the pipe must be at least 500 cm.

Fifth step. Attach the expansion tank to the top of the barrel. You can buy a ready-made container or weld it yourself from sheet metal. A tank of 20-25 liters will suffice.

Sixth step. Weld heating units of suitable length from profile pipes with dimensions of 400x200x15 (focus on the dimensions of the greenhouse). The pipes themselves must be laid on the ground with a step of about 120-150 cm.

Seventh step. Buy and install a hydraulic pump. The system will be heated using water, so it will not be possible to do without a pump.

Any firewood is suitable for the firebox of such a stove. For maximum efficiency install an electronic temperature sensor in the greenhouse, and for greater convenience, place it in a house or other suitable place digital control panel.

A simple and fairly effective greenhouse heating can be built on the basis of an empty fire extinguisher with a cut off top.

First step. Fix on the bottom of the case a heating element (heating element) with a power of about 1 kW. Usually, heating elements of electric samovars and other similar devices have the same power, so there will be no problems finding the necessary part.

Second step. Attach the cut off top of the fire extinguisher to its body with the help of loops.

Third step. Connect two water pipes to the fire extinguisher body. The second ends of these pipes will be connected to the heating battery. Use nuts and rubber seals to fasten pipes.

Fourth step. Install the necessary automation tools. The optimal scheme is using a relay. For example, the MKU-48 model is suitable.

When the temperature in the greenhouse drops below the allowable value, the temperature sensor will close contacts K1 and water heating will begin. The liquid will give the generated heat to the greenhouse. When the water reaches the required temperature, the relay will be powered off and the heater will turn itself off.

You can try to make heating from a heating element and a number of pipes. Even used pipes will do. Recommended pipe sizes are given in the previous section.

The arrangement of such heating will require you to have skills in working with a welding machine.

For heating, a 50 l boiler with a 2 kW heater is suitable. When heated, the liquid will rise into the expansion tank installed above, and from there it will be fed into the laid pipes. Pipes should be laid with a slight downward slope.

First step. Prepare the base for the boiler. The functions of the base can be performed by a piece of pipe of a rather large diameter. A bottom with a flange must be welded to one side of such a pipe.

Second step. Connect the heating elements with an electric wire to the working plug. The wires must be insulated.

Third step. Install a sealing gasket at the joints of the boiler body with the flange.

Fourth step. Make an expansion tank out of metal sheets. A capacity of 25-30 liters will suffice. From both end sides and from the bottom of the tank, weld couplings through which the tank will be connected to the heating system and the riser of your homemade boiler.

Fifth step. Cut out a lid for adding water to the expansion tank.

Sixth step. Prepare the threads at the ends of the heating pipes and connect the pipes into a single system.

Seventh step. Ground the boiler. Grounding is carried out using a copper cable with 3 cores. Two of its cores are connected to the phases of the heating element. The remaining core is launched onto the body of the heating unit.

This heater, as already noted, can be placed in a convenient corner of the greenhouse. You can also allocate a place for the boiler in another room.

Heating with underfloor heating

If there are sufficient Money you can organize the heating of the greenhouse with the help of "warm floor". Modern designs of heated floors are presented in several variations. Choose a suitable system, taking into account the area of the greenhouse and the main conditions for the further operation of heating. The most commonly used systems are made in the format of a waterproof heating mat.

First step. Remove about 40 cm of soil.

Second step. Fill the bottom of the resulting recess with a layer of sifted sand. A 5-10 cm layer of backfill will suffice.

Third step. Place insulation in the hole. It is best to use moisture-resistant materials such as polystyrene foam, polyethylene foam, etc.

Fourth step. Lay waterproofing material on the insulation. Usually polyethylene film is used.

Fifth step. Spread about 5 cm of sand over the waterproofing. Moisten the filling with water. Wet sand must be compacted with high quality.

Sixth step. Lay the "warm floor" wire on top of the compacted sand backfill. Usually the heating element is laid in a "snake". Lay the cable in increments of about 15 cm.

Seventh step. Fill the installed heating system with a 5-10 cm layer of sand.

Eighth step. Lay a chain-link mesh on the backfill.

Ninth step. Fill the resulting "pie" with previously dug soil.

To ensure better and safer operation of the heating, it is recommended to connect a thermostat and a temperature control sensor to the warm floor.

Thus, there is nothing complicated in self-arrangement of heating a greenhouse. You just need to choose the appropriate option and do everything in accordance with the instructions.

Heating the greenhouse is the key to a rich harvest

Video - Do-it-yourself heating of a greenhouse in winter

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 an early harvest, when it is still not warm enough outside 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

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

For fire safety purposes, 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.

To implement 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.

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

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 of the cost of fuel

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 heating intensity 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 thermal return.

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 prices

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 a sheet metal stove 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.

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 as an additional source of 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.

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. On the www portal posted a large number of a variety of 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 operation. Greenhouse heating is one of the major tasks, which directly affects the profitability and efficiency of growing greenhouse vegetables. To solve this problem, you can seek help from specialists, but it will be much more economical for 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 costs (low cost of the 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, do not forget about the performance of 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.

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 is if a heating main passes under the summer cottage. 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 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 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 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 unequivocal, 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

Take a piece of steel tube with a diameter of 500-600 millimeters and a length of about 2-2.5 meters.
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.
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:

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

Solar batteries

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

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

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

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 in the required quantities to ensure a full-fledged 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 is interrupted.

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:

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.
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:

A barrel with a capacity of about 3 cubic meters is taken. To prevent it from rusting, we paint it inside in two layers.
Then holes are made inside it for the chimney and stove.
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.
Now the chimney is removed from the tank. From the outside of the greenhouse, a pipe 6 meters high is placed on it.
Then, an expansion tank welded from a sheet of iron with a capacity of 20 liters is installed on top of the barrel.
After that, a profile pipe 40x20x1.5 is taken, 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.
The water in the system must circulate. To do this, you need to purchase a pump. Any wood can be used as fuel.
The drain cock at the bottom of the tank can be used both for drip irrigation and for draining water. Climatic conditions and the temperature in this case is 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.
