To enjoy garden vegetables and fruits all year round, you need to take care of winter heating for the greenhouse. Previously, this approach was popular among farmers, but now ordinary gardeners are also interested in it.
In this article we will talk about how to build a winter greenhouse with heating with your own hands, which are heating systems greenhouses and how to make heating in a greenhouse with your own hands.
Heating the greenhouse: ways
How to heat a greenhouse in winter? Now there are many ways to make in a greenhouse heating do it yourself. Each of them has its own advantages and disadvantages, therefore, in order to choose the ideal option for heating the greenhouse do it yourself, you need to pay attention to the following selection criteria:
- greenhouse size;
- financial opportunities;
- climatic features of the region;
- the need of different greenhouse plants for heating.

This is the most natural way of heating... In order for the sun to heat the greenhouse better, you need to place it in the sunniest place and choose a suitable covering material. The ideal coverage is considered glass.
The sun's rays pass through the coating, heat the earth and the air. Heat is returned much weaker due to the density of the structure and the covering material. A greenhouse in a mold heats best hemispheres or arches.
- environmental friendliness.
- in winter, this method can only be used in the southern regions;
- temperatures can drop dramatically at night, killing plants.
How to heat a greenhouse in winter? The next way to heat a greenhouse in winter is electric... For a small and sealed facility, this would be ideal.
There are different ways electric heating greenhouses in winter:
- convection systems;
- water heating;
- infrared heating;
- cable heating;
- Heat pump.
Greenhouse heaters have different mechanism of action.
The common advantage of such structures is that they react to temperature changes and automatically create ideal microclimate... With the correct placement of electric heaters, the greenhouse will heat up evenly, which will significantly improve plant growth.
- mobility (most of these devices can be adjusted to the parameters of any greenhouse);
- with a shortage of heaters, the air will warm up unevenly;
- the possibilities of heating the soil are very limited.
System air heating installed during the construction of the greenhouse. Its installation is very difficult, so a specialist must deal with this matter.
How to make greenhouse heating? Special heating and ventilation devices are installed in the base of the foundation and in the frame of the building, which distribute warm air at the top of the greenhouse. Thanks to this, hot air does not get on the plants themselves and does not burn the delicate leaves of the seedlings.
To heat the soil, you can install around the perimeter of the greenhouse perforated heating sleeve.

Underfloor heating system
With the help of "warm floor" you can heat the soil. Such a system can be made for heating the greenhouse in winter with your own hands. Installation of the structure is simple: you need to remove part of the soil, fill the trenches with sand, put a layer of heat-insulating material, lay the cable with a snake and again fill it with sand and soil.
This system allows save on installation and operation. In addition, its advantage is the ability to automatically regulate the heating and distribute heat evenly throughout the greenhouse.
Villagers still use the easiest way to heat greenhouses - biological... In this case, heat is released due to the decomposition of organic substances by microorganisms. Horse manure is usually used as a heating substance, since it is able to reach temperatures in 60–70 ° C for a week and keep it up to 120 days.
- the air of the greenhouse is saturated with carbon dioxide, useful for plants;
- manure also serves as fertilizer;
- due to vapors, the air and soil are constantly humidified.
- in the southern parts Of Russia this method is suitable for winter, but for Ural it is advisable to use it only in the spring;
- horse manure is difficult to find, and other organic substances (compost, garbage) take longer to heat up and lose heat earlier.
Making a bed of manure is easy: you need to remove all the earth from it, fill it with horse manure on 1/3, and then lay out the soil again.
How to heat a greenhouse in winter? Stove heating has long been used by garden owners.
In winter, an ordinary stove stove can maintain the optimum air temperature in the greenhouse for a long time - about 18 ° C.
However, this method is only suitable for southern regions of Russia: such a stove cannot cope with Siberian frosts.
Dignity stove heating is economical: materials for a stove-stove are relatively inexpensive and installation is easy to carry out with your own hands.
Heat can be obtained using any solid fuel - firewood, coal, sawdust, rags, packaging materials. The resulting waste, ash and ash, can be used to fertilize the beds.
Disadvantages of stove heating:
- the air does not always warm up evenly: a high temperature zone forms next to the stove, in which plants can die;
- stove-stove - a fire hazardous structure, therefore, you need to be especially careful about thermal insulation;
- laborious heating process: the structure will function properly only if fuel is regularly tossed into the stove.

Diy potbelly stove
Such heating for greenhouse you can do it yourself. To do this, you will need the following materials and tools:
- heat-resistant metal sheets;
- pipes of the same diameter made of cast iron, steel or ceramics;
- metal rods and corners;
- tape measure and plumb line;
- grinder or scissors for metal;
- welding machine;
- bolts and couplings;
- burnt brick;
- clay and lime mortars.
Construction, its location and foundation
One potbelly stove can heat the space in 15 m2... There must be at least 30 cm between the heating elements of the structure and the walls of the greenhouse.
If the greenhouse is made of a material that melts easily (polycarbonate, polyethylene), then this distance should be doubled.
The heating structure consists of:
Fuel burning in the firebox emits warm smoke... With the help of a chimney, it spreads throughout the greenhouse, heating the air, and then exits through the chimney.
Do-it-yourself heating of the greenhouse with a potbelly stove:
To make such heating of the greenhouse in winter with your own hands, you first need to do foundation... Thanks to him, the stove will not warp, its legs will not fall into the ground, and the risk of fire will be minimized.
- For the foundation you need to prepare pit depth of 0.5 m. Its area depends on the size of the stove. If it is supposed to cover the finished stove with brickwork, this must be taken into account when digging a pit.
- A mixture of sand, fine gravel and brick fragments must be poured into the finished pit. A layer of 15–20 cm will be sufficient.
- Now you can install wooden formwork: the boards must be placed along the perimeter of the pit, and the gaps between them and the walls of the pit must be covered with sand.
- In the hole bounded by the boards, you need to pour cementand then bed roofing material... This will provide additional waterproofing and the foundation will last longer.
- The final touch is laying bricks... They are placed on roofing material in two layers, secured with a clay-sand mortar.
Advice! To make the design even, after each step you need to check with the plumb line.
There are different designs stoves, but the simplest is the usual rectangular oven... It is better to install it in such a way that the combustion hole goes out. This will facilitate the heating process, and the possibility of smoke generation in the greenhouse will decrease.
- The size of the stove will depend on the size of the greenhouse. Average parameters: width - 30 cm, length - 40 cm, height - 45-50 cm. Such a stove can heat 10-15 m2 space. Given these features, you need to draw a diagram of the future design.
- The firebox is made from any heat-resistant metal... The sheets need to be marked and cut out structural elements (bottom, walls and roof) with a grinder or metal scissors.
- Now you should weld the bottom and three walls. Inside, to the height ¼ from the bottom, you need to weld metal corners. A lattice is laid on them.
- The grate can be bought at the store or made yourself from metal rods. The rods are welded together in such a way that a grid with holes is obtained 1-4 cm2... The size of the holes will depend on the future fuel. The grate will hold the fuel, and the combustion products - soot and ash - will pass down into the ash box.
- In the future roof of the stove, you need to cut a hole for a chimney with a diameter 13-15 cm... The roof can then be welded to the structure.
Important! If the chimney is to be placed underground, then the hole can be made not in the roof, but at the bottom or in one of the walls.
- On the front wall of the oven, you need to make two holes: through one, the fuel will be put in, and the second will be used as a blower. Through it it will be possible to clean the ash from the stove. Hole doors must be cut out of sheet metal and attached to the wall using hinges. The handles should be attached to the doors.
- Now you can weld the front part to the stove. If it is planned to place the combustion hole outside, it must be covered heat insulating material... Otherwise, the heated metal in contact with the parts of the greenhouse will melt them.
- A short section of pipe must be welded to the hole in the roof, to which it will subsequently join chimney.
- Metal legs must be welded to the bottom or ends of the stove and fastened with a jumper. This will add constructs sustainability.
- To reduce the risk of fire and increase the heat dissipation time, you can overlay the stove brickwork... This material retains heat longer: thanks to it, the stove will have to be heated less often.
Chimney can be made either from a solid pipe, or from pipe sections of equal diameter. If the greenhouse is small and air heating is sufficient, chimney can be laid above the ground. If soil heating is required, an underground structure will do.
- Pipe sections for chimney need to be fastened together. To do this, you can use a welding machine or special couplings (clamps). In the latter case, the joints between the pipes under the couplings are coated with clay.
- Chimney must be connected to the furnace with the same couplings or welding.
- If you intend to place chimney underground, you need to dig shallow trenches (25–40 cm) and lay parallel pipes in them. The distance between the pipes should be from 60 to 100 cm. The pipes are covered with expanded clay or fine gravel, and their ends are taken out of the greenhouse. This design will be an ideal replacement "Warm floor".
- If a chimney it is overhead, it needs to be installed on props. It is best to place it at a slight angle so that the end adjacent to the chimney rises slightly. This will increase your cravings.
- Overground chimney need to be covered with lime or chalk. Any deformation or rust marks will be visible on the white surface. This will help you easily monitor the state of the structure.
This part of the design will allow smoke out outside the greenhouse.
- You need a pipe weld to the chimney and cover with heat-insulating material so that it does not melt when it comes into contact with the greenhouse roof.
- On top of the pipe you need to put on spark arrester... You can buy it in the store or make it yourself.
This will require a piece of flexible metal wire rack or a regular tin can.
You need to make many small holes in the jar, and simply twist the grate into a cylinder.
- To prevent debris and precipitation from getting into the pipe, it must be covered metal cone.
It can be made from a piece of tin or bought from a store. This structure can be fixed to the pipe with thick wire.
- To regulate traction, a metal shutter... It is welded to a piece of thick wire. The ends of the wire are led out from both sides of the pipe. By turning the ends of the wire, you can change the position of the shutter and adjust the draft.
Advice! The damper can be closed only after the fuel has completely burned out. Otherwise carbon monoxide can go to the greenhouse.
It can be installed next to or on top of the oven water tank... It will allow you to water the plants with warm water all year round. In addition, the water next to the stove will maintain an optimal level of humidity in the room, which will have a beneficial effect on the condition of green residents.
Now you know how to do heated greenhouse do it yourself. With a warm greenhouse, you can get an excellent harvest even in winter. You just need to choose the right one heating method... For the southern regions, any method is suitable, but residents of the north should give preference to electric heaters.
DIY greenhouse with heating will delight you year-round tasty and healthy harvest!
