Heated greenhouses with their own hands. How to heat a greenhouse without gas and electricity in the winter?

Almost every country house and vegetable garden of the private sector has a greenhouse. They are used mainly in the spring-summer period for growing seedlings and summer thermophilic vegetables. And sooner or later each owner of the greenhouse starts to think about its profitability. Increase its efficiency can only be when you use it all year round, or when growing very early products, when the market and the store is very expensive. Now it has become fashionable to create winter gardens and grow greens, radishes, cucumbers for the New Year and flowers on the 8th of March in the cold season. Of course, it's great to have fresh food from your greenhouse in the winter, but for this you need to make it heated, because the winters are long and harsh.

To heat a greenhouse means to increase its efficiency

But for early or all-the-year-round use of the greenhouse you need heating, because there are severe frosts in the winter, and in the early spring minus air temperatures are not uncommon. And then the question arises as to which heating to choose, which is acceptable personally for your household farm, because any of them requires a financial investment. Here you need to estimate what you have enough money for and what heating will be less expensive to maintain. In addition, we must take into account the longevity and efficiency of the selected type of heating.

Heating greenhouses - the most important part of the microclimate in the life of plants, like watering. Think about how it will be, preferably before the start of construction. It is better to do immediately, as it should, then not to remodel. Consider different methods of heating, pluses and minuses of the selected options and choose what is most convenient and least expensive.

How to heat a greenhouse in the early spring?

In order to grow seedlings and early summer products, it is not necessary to use any heating. To do this, it is enough to make the beds of the greenhouse on the overriding manure. It is necessary to remove the fertile soil layer, instead of beds, trenches will be obtained. It is desirable to make boards for future warm beds from boards or other improvised materials. At the bottom lay a thick layer of overmatch manure, mixed with straw or peat. Top the fertile soil layer. Denying the dung below will give off heat and moisture. Plants planted on high warm ridges will feel comfortable.

When the street is still cold, then on the greenhouse you can pull the second layer of film. Between the main layer and the additional one, an air cork is formed, which will also store heat. The greenhouse should be placed so that it was in the sun for as long as possible. The sun's rays will penetrate through the film or honeycomb polycarbonate and heat the surface of the earth in the greenhouse. Thus, natural heat will condense in it. This is how you can "naturally" heat a greenhouse, just do not make the roof too high, then it will warm up more. Experience has shown that the highest efficiency in terms of heat conservation in greenhouses with arched construction.

But there are minuses. If you do not have your manure, then it will have to be bought, and this is now quite expensive. In addition, it must be stored from autumn. And the ridge to do every spring anew. This is a very time consuming process. Heated hothouses can not be done with their own hands. And in the winter of such "heating" will be small.

Stove heating

How to heat a greenhouse without gas and electricity? One such method is furnace heating. They make an ordinary oven, from it horizontally they start a chimney along the walls of the greenhouse. It should gradually rise upward and finally be led outward. Thus, the greenhouse will be heated. The firebox should be made so that it opens outside the greenhouse, because it is impossible to penetrate the soot and smoke into it. Then the quality of vegetables will suffer.

You can install a stove with a boiler in which water will be heated, and then it will circulate through pipes that will be laid on the ground along the length of the greenhouse. Hot water will heat the air.

If the efficiency of such systems can satisfy the user, then the laboriousness of the process is very tiring. The fact is that one must constantly monitor the temperature, often pour solid fuel. Not everyone can quit his job and be a stoker in his own greenhouse all winter. And is it worth it?

When constructing heated greenhouses with your own hands, it should be borne in mind that the film and glass do not hold heat well, and therefore they should be better heated. Cellular polycarbonate, because of its design, keeps the heat well, and therefore the cost of heating will be less.

Heating with heat-generating boilers is also a good form. Unlike simple stoves, the heat generator must be recharged with solid fuel no more than twice a day. There are systems on diesel fuel. The efficiency of such heating is not the highest.

Heating with gas

Gardeners are interested in how to make a heated greenhouse on gas. If it is small, then balloon gas can be used. If the greenhouse has an industrial scale, then it is necessary to take a permit and use the natural one. For heating the gas using conventional burners and with infrared. Also, a conventional water heating system based on AGW is used. Gas, of course, is beneficial, because it is cheaper than electricity.

Using such heating with burners, it is necessary to do ventilation, and this already lowers the heating efficiency. If you make water heating based on heating the water with water, the system can be fully automated. Without the constant control of a person, the microclimate in the greenhouse will be maintained. The main thing is that it is profitable from a financial point of view, and the costs could soon pay off.

Heating by air heating

How to heat a glasshouse made of polycarbonate by heating air? This heating can work on liquid fuel and on electricity. It is often used in large greenhouses. The unit heats the air, which is directly blown in the center of the greenhouse and circulates along polyethylene perforated sleeves, spread out along the length of the building. Thus, the air inside is heated.

Convectors also fit

You can heat the greenhouse with electric convectors. They are installed on the walls of the structure and on the floor. Convectors warm the air well, they have timers that can be set to a certain temperature, and they will turn on and off. Some drawbacks - they are quite energy-intensive, and electricity is now expensive.

Hot air heating

A lot still can be used to heat a greenhouse in winter. Some are heated with portable heat guns (fans), heaters. These devices actively blow out hot air, rapidly heating the room. The main thing is to arrange them so that they do not dry and do not burn the plants. Well, if they are equipped with thermostats. Then you do not need to follow them constantly, just set the desired temperature, which they will support.

Warm floors in the greenhouse

The heated greenhouse made of polycarbonate can be made with complex heating. After all, it is necessary to heat not only the air, but also the soil in which the plants grow. For this, some use the construction of "warm floors". Lay a sand cushion, on it - a protective mesh, then a heating element or cable, then again a protective mesh and a sand cushion on top. Then pour the soil layer up to 20 cm. It is necessary to install the thermostat so that the soil does not warm up more than 45 degrees, otherwise the roots of the plants may suffer. This method of electric heating is very economical, with high efficiency. On top of the greenhouse the sun warms up, cellular polycarbonate keeps the heat. From below the soil is also heated, and the heat from it rises.

The most effective method of heating

There is another way how to heat a polycarbonate greenhouse in winter. These are infrared lamps and heaters. These devices are good because they do not dry the air and act like solar energy. The sun's rays, as is known, reach the surface of the Earth, they heat objects and are reflected by heat. Also, there are lamps and heaters with infrared radiation. If they are placed along the entire length of the greenhouse, under the ceiling, they will heat the soil, plants, walls, and, reflecting, heat will accumulate in the room. They are absolutely harmless, with very high efficiency. Because the heat is much, and the energy costs are small at the same time. Such heating can be easily adjusted to create the necessary microclimate in the greenhouse.

Perhaps, for today it is the safest and most profitable method to heat a greenhouse in the winter.

It is important not only to heat the greenhouse, but also to save heat

In order for the greenhouse business to be profitable, it is necessary not only to heat the greenhouse well, but also to use all possible means to preserve this heat as best as possible.

To do this, it is good to apply all the knowledge in a complex. Successfully chosen place to build a greenhouse, no shade, all day under sunlight. The greenhouse should be located so that the wind does not blow out heat. Good, warm foundation. The greenhouse is better than honeycomb polycarbonate. In the design there should be no cracks: in winter in the frost any draft is ruinous.

It is possible to apply warm high beds with manure, which will also accumulate heat. You can grow seedlings on racks. It is good to combine the heating of the greenhouse: to raise the temperature of air and soil. By the way, for the effect of warm floors you can use waterproof mats. They are convenient to use in greenhouses with shelves, placing heat mats under them. Heat always rises from below, heating pallets with plants and air.

Make heating yourself or order it ready?

You can not even invent a bicycle, and ordering a greenhouse, immediately buy a heating system and complete maintenance of the microclimate. Experts will deliver the design and install in the shortest time. They equip it with all the necessary options, which is called "turnkey", and they will also give a guarantee.

Everything, of course, depends on your financial capabilities and desire. Every year, new products appear on the market that will help make the greenhouse payback year-round. What kind of heating you want to do depends, of course, on how you want to use it: year-round to grow something or in the early spring and summer.
