DIY greenhouse heating: the best projects (video)

How to heat a greenhouse in early spring?

When considering options for heating a greenhouse in winter, one must remember the following important points:

The temperature inside the greenhouse should never exceed 40 ° C. Excessive heat can simply dry out the plants.
To heat each cubic meter of indoor space, the selected heating device must produce 100 W of heat.
Soil heating is ideal for heating. If heat exchangers are used, then they must be located at the lowest possible height.

The easiest and most natural way is with the sun. To use the energy of the heavenly body to the maximum, the greenhouse should be placed in the place on the site where the most sunlight falls - this way the plants will receive the maximum amount of heat and light.

Experienced gardeners have found that it is best to heat a greenhouse in the form of an arch or hemisphere in the sun.

For solar heating to work effectively, the greenhouse roof must be completely transparent. Then the sun's rays will be able to freely pass inside and heat the plants and soil, which will give off heat, thereby heating the air in the greenhouse.

The undoubted advantages of the solar heating method are efficiency and environmental friendliness, but a significant disadvantage is the fact that this option is not suitable for the northern regions.

It is not necessary to use any kind of heating to grow seedlings and early summer produce. To do this, it is enough to make greenhouse beds on overheated manure. It is necessary to remove the fertile soil layer, instead of the beds, trenches will turn out. It is advisable to make boards for future warm beds from boards or other materials at hand.

When it's still cold outside, you can stretch the film onto the greenhouse with a second layer. An air lock will form between the main layer and the additional layer, which will also retain heat. The greenhouse should be positioned so that it stays in the sun for as long as possible. The sun's rays will penetrate the foil or cellular polycarbonate and heat the surface of the ground in the greenhouse.

But there are downsides. If you do not have your own manure, then you have to buy it, and this is now a rather expensive pleasure. In addition, it must be stored in the fall. And do the ridges every spring anew. This is a very time consuming process. DIY heated greenhouses are not easy to do. And in winter there will be little such "heating".

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.

For this, it is good to apply all knowledge in a complex. Well-chosen location for building a greenhouse, no shade, all day under the sun. The greenhouse should be located so that the wind does not blow out the heat. Nice, warm foundation. The greenhouse cover is better made of cellular polycarbonate. There should be no gaps in the structure: in winter, in frost, any draft is destructive.

You can use warm tall beds with manure, which will also accumulate heat. You can grow seedlings on shelves. It is good to combine heating of the greenhouse: increase the temperature of the air and soil. By the way, waterproof mats can be used for the effect of underfloor heating. It is convenient to use them in greenhouses with shelving, placing heating mats under them. The heat always rises up from the bottom, heating the trays with plants and the air.

Heating methods

Naturally, the heating of the greenhouse in winter can come from various sources, which allows you to choose the most inexpensive and efficient option for a particular area.

Heating can be provided in two ways:

With electric heaters.
By burning fuel.

The variety of electrical appliances that can be used to heat a winter greenhouse is quite extensive.

It can be:

Ordinary air heaters.
Underfloor heating systems for the home.
Or infrared heaters.

So:

Although such devices have a common source of energy, they operate with different efficiency and power consumption.
With electric heating, automatic thermostats can be installed to maintain constant parameters for optimal plant growth.
Also, heating the greenhouse in winter can be done by burning fuel.
Conventional wood-burning stoves can be used, as well as more technical long-term boilers or gas burners.

It all depends on the available fuel sources, for which the heating system in the greenhouse is adjusted.

Electrical appliances with heating elements

It should be noted that the installation of winter greenhouses with air heaters is the most ineffective way of heating.

This is due to the fact that the heater heats only the air, and the earth, in which the plant roots are located, remains cold:

This effect occurs because warm air always accumulates under the ceiling and does not come into contact with the soil in which vegetables and herbs are planted.
As a result, the main part of the plant is in relative warmth, but good development has not been observed.
In addition, the heater consumes too much energy with low efficiency, which often makes the cultivation insufficiently profitable.
If there is no alternative, you can install heaters under the racks with seedlings, then during their operation the roots will also warm up.

Note. Since the heater is small, the rack will not be heated entirely, but only in the immediate vicinity of the heating source.

The electric underfloor heating system is more preferable for greenhouse conditions, as it helps to warm the soil and plant roots. As a result, the air in the greenhouse is already heated from the ground. Such a system contributes to obtaining a high yield and at the same time significantly lower energy consumption.

Infrared heating

It is the most effective and economical means of electric heating of greenhouses, since it is not the air that heats up, but the soil and plants directly.

This is due to the principle of operation of infrared devices, in which infrared rays are converted into thermal energy only when in contact with solid objects such as soil and plant stems.

Since the transfer of infrared heat over a distance is practically lossless, heaters of this type are installed on the ceiling.

Note. There is also a special IR film developed exclusively for arranging greenhouses, which is buried in the soil to a depth of 30-50 cm, thereby heating the ground more efficiently and at the same time, without interfering with the roots of proper development.

Arrangement of a year-round greenhouse

For a long time there have been ready-made greenhouse structures on sale with the provided high-quality heating. It is necessary in harsh climatic conditions for both farmers and private traders. If you wish, you can prepare a regular greenhouse for use in the winter.

Heating in a greenhouse will help grow crops in winter
It is advisable to insulate the base so that hypothermia of the soil does not lead to a decrease in yield:

The foundation can be a wooden platform. It is treated with an antiseptic and covered with a waterproofing material.
The second option is pouring with concrete with further foam insulation.

Glass perfectly transmits light, but its weight and inability to bend complicates installation, and its high thermal conductivity does not allow maintaining a stable temperature throughout the day. Polycarbonate greenhouses are the highest quality designs for year-round use. Having made heating in a polycarbonate greenhouse with your own hands, you can be sure of good early harvests.

Polycarbonate panels are one of the best materials for creating greenhouses, including year-round ones. This material is strong enough and is not subject to the destructive influence of the external environment (for example, temperature drops, high humidity).

At the same time, it is very convenient to work with such material - it is mounted on the frame of the greenhouse with the help of self-tapping screws, it bends well.

The most important advantage of such greenhouses is the ability to use it all year round, grow plants all the time and get fruit. It can be both a variety of greens and other vegetables.

Having installed all the necessary systems, you can create any necessary temperature conditions inside. In addition, the greenhouse does not need to be cleaned after every season.

It is a building that can be used for many years with proper maintenance.

Stove heating

How to heat a greenhouse without gas and electricity? Stove heating is one such method. They make an ordinary stove, from it horizontally they let a chimney along the walls of the greenhouse. It should gradually rise up and finally be brought out. This will heat the greenhouse. The firebox must be made so that it opens outside the greenhouse, because it is impossible for soot and smoke to penetrate into it. Then the quality of the 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 you need to constantly monitor the temperature, often throw up solid fuel. Not everyone can quit their job and be a stoker in their 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 keep heat well, and therefore they need to be better heated. Cellular polycarbonate, due to its design, keeps heat well, and therefore the cost of heating will be less.

Heating with heat generating boilers is also a good sight. Unlike simple stoves, the heat generator with solid fuel needs to be charged no more than 2 times a day. There are diesel fuel systems. The efficiency of such heating is not the highest.

Greenhouse air heating

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

First step. Buy or find an unnecessary steel pipe on the farm. A piece 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. The other end of the pipe must be brought out into the street. A fire is made under the "street" end of the pipe.

Greenhouse air heating

The outdoor air will be heated by a fire flame and into the greenhouse through a pipe. Heating is really very simple in its organization, but you cannot 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.

What should be the greenhouse?

All greenhouses work in a similar way.Winter greenhouses have some features that must be observed during construction.

A winter polycarbonate greenhouse is a stationary building and requires the creation of a high-quality foundation and a solid frame.

A prerequisite for creating a year-round greenhouse is a capital foundation. A wooden foundation will not work, because it needs to be changed periodically.

The best option is a concrete, brick or block foundation. The strip foundation is created along the perimeter of the structure, it is quite simple to install and at the same time relatively inexpensive.

The second important point is the greenhouse frame. Winter use assumes periodic snowfalls. The accumulation of snow on the roof leads to very heavy loads on the frame, which can lead to the destruction of the entire structure. The frame can be made of wood or metal.

Both materials are susceptible to destruction and will require preliminary preparation, and in the future - prophylaxis and periodic replacement of unusable elements.

Preparation for construction

On the network you can find a lot of ready-made solutions for the construction of greenhouses and adapt them to your needs. You can also create your own drawing based on your needs and wishes.

There are special programs for creating drawings. They allow you to see the finished model of the future building.

In any case, when creating a greenhouse with your own hands, you need to pay attention to several factors.

First of all, you need to choose a place for further construction. You need to choose based on three main factors:

Illumination. The greenhouse should receive the maximum possible amount of solar energy.

To maximize the amount of sunlight, the greenhouse can be positioned along its length from west to east.

Wind conditions. Strong and gusty winds are not only the risk of collapse of the structure, but also large heat losses. Therefore, wind protection is necessary. For example, you can place a greenhouse next to the wall of the house or plant low perennial plants at a distance of 5-10 meters.
Convenience. Access to the heifer should be wide enough and convenient, which will greatly facilitate the maintenance of the building.

Then you need to choose the shape of the roof of the future structure. Most often it is a gable or arched roof.

The shape of the roof should resist the accumulation of snow during the cold season. The gable roof is the easiest to install.

The material of the frame is also important. The strongest and most durable material is metal.

But it is important to remember that the creation of a metal frame will require welding to erect the structure. On the other hand, the tree does not require special tools or skills, it is quite affordable.

And if you additionally open it with several layers of paintwork, then it can serve for many years. By slightly strengthening the structure, you can achieve high strength and stability.

It is also worth mentioning the choice of polycarbonate. What is the required thickness of polycarbonate for a winter greenhouse? If a fairly thin sheet (6-8 mm) is suitable for an ordinary greenhouse, then panels with a thickness of at least 8-10 mm are needed for winter greenhouses. Otherwise, there is a risk that the panels will not withstand the load, and heat will be poorly retained inside the building.

One of the key features of a winter greenhouse is a heating system. What kind of polycarbonate greenhouse heating to choose in winter? How to make heating in a polycarbonate greenhouse in winter with your own hands? How to heat and insulate a polycarbonate greenhouse for the winter with your own hands using stove heating?

Heating with electrical appliances such as infrared heaters is becoming more and more popular.How to arrange heating of a polycarbonate greenhouse with infrared heaters?

Installing such a system is very simple - you just need to connect the electrical network to the greenhouse and connect the electrical appliance. You will need to spend money on the heater itself and electricity.

Infrared polycarbonate greenhouse heaters are installed on the ceiling and are capable of providing an air temperature inside up to 21 degrees Celsius, and a ground temperature up to 28 degrees.

The alternative is the old and traditional stove heating method.

It is much cheaper and easier to install. However, its disadvantage is the strong heating of the walls; it will not be possible to grow plants near it.

Finally, the foundation of the entire building must be made capital and stable, because the strength of the entire structure depends on it. Its creation does not require any complicated steps and can be done by anyone.

Construction work must be carried out in dry weather with a positive temperature.

Heating with a "warm floor"

Warm floor in a greenhouse

If you have sufficient funds, you can arrange heating of the greenhouse using a "warm floor". Modern floor heating designs are presented in several variations. Select a suitable system taking into account the area of the greenhouse and the basic conditions for the further operation of the 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. Cover the bottom of the recess with a layer of sifted sand. A 5-10 cm layer of backfill will suffice.

Step three. Place insulation in the pit. It is best to use moisture resistant materials such as expanded polystyrene, polyethylene foam, etc.

Fourth step. Lay waterproofing material on the insulation. Plastic wrap is usually used.

Fifth step. Spread about a 5 cm layer of sand over the waterproofing. Moisten backfill with water. Wet sand must be tamped properly.

Sixth step. Lay the underfloor heating wire on top of the compacted sand backfill. Typically, the heating element is laid in a "snake". Lay the cable in approximately 15 cm increments.

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

Eighth step. Lay the netting on the backfill.

Ninth step. Fill the resulting "cake" with the 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.

How to make warm beds

Thus, there is nothing difficult in the independent arrangement of heating a greenhouse. You just need to choose the appropriate option and follow the instructions.

Instructions

How to build a polycarbonate winter greenhouse with your own hands?

Creation of the foundation.

For a stationary greenhouse, a strip foundation will be optimal. To install it, you need to dig a trench about 30-40 cm deep around the perimeter of the future building. A small layer of gravel and small stone (5-10 cm thick) is poured onto the bottom. Then the entire trench is poured with a layer of concrete.

When creating a mortar, a mixture of one part of cement and three parts of sand will provide the best quality.

After the solution has frozen, you can proceed to the installation of the next layer. A layer of waterproofing is laid on the foundation layer (roofing material is suitable). Then the greenhouse base is formed. A wall of small height is laid out of bricks. A wall thickness of one brick is enough. For construction, not only new, but also previously used bricks are suitable.

After creating the base and complete solidification of the solution, you can proceed to the installation of the frame.

Installation of the frame.

The simplest and most affordable option for creating a frame is a wooden frame. Its installation does not require special knowledge or skills, as well as welding. It is important to pre-prepare the wooden elements before installation.

First you need to clean the elements from dirt and adhering soil with a brush, then sand with fine sandpaper. Then rinse with running water and allow to dry completely.

After that, you can proceed to applying paint and varnish coatings. Paint for outdoor use, resistant to high humidity and different temperature conditions, is best suited. After the paint has dried, you can apply a couple of coats of varnish on top.

A good way to protect the wood is to impregnate it with epoxy prior to painting.

Now a beam with a section of 100x100 mm is installed along the perimeter of the foundation. To create a roof, you can use a beam with a section of 50x50 mm. When building a roof, it is necessary not to allow areas without support for more than 1 meter. Also, several supports should be placed along the ridge to further strengthen the structure.

For maximum strength, you can also create a plank strapping.

The elements are fastened with self-tapping screws and metal tape.

You can add a small vestibule at the entrance to the greenhouse. This will reduce heat loss when entering and exiting the greenhouse.

Installation of communications.

The next stage is associated with the installation of a heating system, lighting and other necessary communications.

Lamps are installed along the ridge of the roof, sufficient to illuminate the entire room. For convenience, all switches are best placed near the entrance.

When installing a stove heating, a chimney is installed. It is important to remember that when the oven is operating, the chimney pipes get very hot and can melt the polycarbonate panels.

Installation of polycarbonate panels.

The final stage of creating a winter greenhouse is the installation of polycarbonate sheets. The sheets are fastened together using an H-shaped profile. From the ends, a U-shaped profile is mounted on the panel. The sheets themselves are installed vertically, then moisture flows better through them.

Do not fasten the sheets too rigidly. Polycarbonate expands when heated, and too rigid an installation can lead to cracks.

Polycarbonate is fastened with self-tapping screws with a seal. The seal prevents moisture from entering through the holes. Before installation, holes are made on the sheets with a diameter slightly larger than the self-tapping screw. A special sealing tape is laid between the frame and the panels.

The greenhouse is then ready for use.

It is somewhat more difficult to create a winter greenhouse than an ordinary one, but everyone can do it and does not require special skills.

In addition, the creation of such a greenhouse does not require serious financial investments. And the result in the form of fresh food throughout the year is worth the effort.

Underfloor heating in a greenhouse

A heated polycarbonate greenhouse with your own hands can be made with integrated heating. After all, it is necessary to heat not only the air, but also the soil in which the plants grow. For this, some people use the "warm floors" construction. A sand pillow is laid, on it is a protective mesh, then a heating element or cable, then again a protective mesh and a sand pillow on top.

Then the soil is poured in a layer of 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. The sun warms up the greenhouse from above, cellular polycarbonate keeps heat. The soil is also warmed up from below, and the heat rises from it.

Gas heating device

Gas heating is distinguished by its advantages - it is silent, lasts for several decades, economical and environmentally friendly (as a result of combustion, mainly safe carbon dioxide is released, which escapes into the atmosphere). The greenhouse heater in the classic version runs on a gas boiler, which is installed in the utility room.

Also, summer residents often use mobile equipment - this is an open-type burner. Conditionally as a gas stove, which can be connected both to the central gas pipeline and to the cylinder (it needs to be changed periodically). This method is very simple, but burning consumes oxygen. Therefore, it is imperative to ensure the flow of fresh air into the greenhouse - especially at night, when the plants do not breathe carbon dioxide, but oxygen. For the ventilation system, next to the fire source, make an opening for an air duct with a diameter of at least 10 cm.

Attention! It is advisable to duplicate one burner with the second one - the one on duty, which operates from a reserve cylinder. This is especially important for winter cultivation of various crops.

A gas burner is the easiest way to heat a greenhouse

A more convenient option for mobile equipment is a catalytic polycarbonate greenhouse heater. They run not only on gas, but also on gasoline and even from the electrical network. They heat the room up to 20 m2 and more (depending on the capacity). Equipped with a fan and wheels, which allows them to move freely to any place.

Catalytic gas heaters, even with a minimum output, serve to heat greenhouses up to 120 m3

The most efficient heating method

This heating option is suitable for small, well-made greenhouses. If the structure occupies a significant area or there are unsealed slots in it through which cold air enters, equipping the greenhouse with electric heating can significantly hit your wallet.

Heat gun

There are pendant and outdoor heat guns. This equipment is based on a high power fan and heating element. When the heat gun is operating, the heated air is blown out under high pressure, contributing to the distant spread of heat in the greenhouse. The disadvantages of this heating method are significant energy consumption and highly heated air at the outlet, which requires careful selection of a place for installing the electrical appliance.

Electric convector

At the heart of this heating unit (like a heat gun) is a thermostat and a heating element. However, the electric convector differs from the latter, first of all, in the principle of operation. Air enters it from below, heats up and exits through the holes provided at the top. Of course, the heat gun will provide faster heating of the air in the greenhouse, but the convector helps to preserve oxygen during heating. Typically, such equipment is installed on the floor or walls, in some cases - on the ceiling. Convectors can be used in tandem with other heating equipment. It should be remembered that electric convectors consume a lot of electricity.

Fan heater

Unlike convectors, which heat the greenhouse evenly, the fan heater directs the hot air flow in one direction. These heating devices are very suitable for heating small greenhouses. They are appreciated for their compact size, ease of installation and good heat dissipation. And for the price they are quite affordable. The fan heater is able to effectively warm up the air in the greenhouse in a short time and provide the plants with a comfortable temperature. Thanks to their compact size, they can be installed anywhere in the greenhouse. It is important that fan heaters during operation not only heat the air, but also provide air exchange inside the greenhouse. One fan heater will be enough to heat the area up to 20 sq.m.

The advantages of the devices listed above are efficiency and mobility. True, there are also enough disadvantages here: with a small number of heaters or their insufficient power, the air will heat up unevenly. And there will be few opportunities for heating the soil when choosing this method of heating.

One of the easiest ways to maintain the desired temperature in a greenhouse is to have a "warm floor", which is used to heat the soil. It is not difficult to arrange such winter heating of a greenhouse with your own hands, even a novice summer resident can cope with this.

The design is pretty simple. The most popular system is a waterproof heating mat. To create a "warm floor" in the greenhouse, up to 40 cm of soil is removed, and pre-sifted sand is poured onto the bottom of the recess with a layer of 5-10 cm. Next, a heater (polystyrene foam, polyethylene foam, etc.) is laid in the recess.

https://www.youtube.com/watch?v=Cc3rFxXcJ2w

The wire of the "warm floor" is laid with a snake over the rammed sand with a pitch of 15 cm. The finished heating system is again covered with a 5-10 cm layer of sand, on which the netting is laid. Next, the "pie" is covered with previously removed soil.

Such a soil heating system in a greenhouse does not require special costs both at the installation stage and during operation. Another plus is the ability to automatically regulate heating and evenly distribute heat throughout the greenhouse.

The most energy efficient way is to heat the greenhouse from below. In this case, warm air does not have to cycle through the entire volume of the greenhouse, as when using other heating devices.

Infrared heating is considered to be one of the relatively inexpensive types of greenhouse heating in winter. Many gardeners have already ditched electric heaters in favor of infrared lamps. These lamps are ideal for heating polycarbonate greenhouses. In addition, they do not shine, but heat the room, and this makes them cheaper in comparison with other devices of this kind.

With the help of infrared lamps, different climatic zones can be organized in one greenhouse. When heated, the soil releases heat into the air. A regulator built into the lamp allows you to create the temperature required for each specific crop. It is important that infrared lamps are easy to install anywhere in the greenhouse.

The indisputable advantage of such equipment is energy savings of up to 60%.

All of these heaters have a different mechanism of action, but in the end they fulfill their main purpose - they create a microclimate necessary for plants in the greenhouse in winter. If placed correctly, electric heaters will help to evenly heat the air and improve plant growth.

Greenhouse heating can be divided into natural and artificial heating methods. Natural, as it is not difficult to guess, consists in creating a greenhouse effect (and, accordingly, heating plants and soil) by solar energy penetrating through the greenhouse cover. This method is great for growing heat-loving crops from around mid-spring.

In addition, it is advisable to choose a place that is reliably protected from drafts that cause cooling of the greenhouse cover.

Natural heating of the greenhouse with the help of sunlight

Of course, this heating method cannot be considered complete when it comes to growing crops year-round. Additional heating is required here, which can create a natural greenhouse effect in the cold season. Among the main methods of heating greenhouses, electric, gas and solid fuel options are most often preferred.

There is another way how to heat a polycarbonate greenhouse in winter. These are infrared electric lamps and heaters. These devices are good because they do not dry the air and act like solar energy.As you know, when reaching the surface of the Earth, the sun's rays heat objects and are reflected by heat. Infrared lamps and heaters also work.

If they are placed along the entire length of the greenhouse, under the ceiling, then they will heat the soil, plants, walls, and, reflecting, the heat will accumulate in the room. They are absolutely harmless, with very high efficiency. Because they give a lot of heat, and the energy consumption is low. Such heating can be very easily adjusted to create the desired microclimate in the greenhouse.

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

Simple and economical natural heating methods are auxiliary. These are energy from the sun's rays and biofuels.

The sun is the most economical form of energy

Solar heating is suitable for regions where the climate is mild and the average winter temperature does not drop below zero. For colder regions, this method is used from March-April. In order for the plants to receive enough light and heat, the greenhouse must be placed in a well-lit area without drafts.

A transparent rounded roof warms up better with the sun's rays. Such an arched shape of greenhouse structures is most resistant to winds and various loads.

The use of biofuels has been proven for centuries. The old folk method is based on the ability of organics to release a large amount of heat during decomposition. Experienced gardeners use this to equip warm beds by mixing pet manure with compost made from rotten straw, bark, grass, leaves, or unusable fruit. Horse manure heats up especially quickly.

Manure will fertilize, and at the same time insulate the soil

Instead of manure, you can use special dry briquettes that do not have a specific smell, but work just as effectively. To start, biofuel is slightly added to the well-loosened soil. When steam begins to flow from the beds a week later, they can be covered with fertile soil and seedlings can be planted. High warm beds are convenient and practical in terms of caring for them.

Natural cheap methods are auxiliary, because solar energy is not always enough to heat the greenhouse, and biofuel begins to decompose only at a certain temperature regime.

Heating

Depending on where you live, you can decide if you need additional heating. ... Winter greenhouse heating methods:

Solar energy. Everyone knows that the air in winter has a fairly low temperature. But the sun's rays carry enough heat and energy. Its use is quite effective, low-cost, and most importantly environmentally friendly. The use of polycarbonate helps to diffuse sunlight over the greenhouse space. The sun heats the air to optimal temperatures, and polycarbonate prevents it from escaping. This heating method is effective if you live in an area where the sun in winter is quite frequent, and low temperatures are rare. Is a fairly well-known greenhouse effect. But such heating of greenhouses has a significant drawback - it is impossible to control the sun and the sun's rays. It is also impossible to foresee the level of solar activity. So this method, although effective, is quite unpredictable.

Biological system. This heating method can be called the most ancient, proven, low energy consumption and effective. Everyone is well aware of the fact that biological products generate heat during decay. With their help, you can perfectly heat not only air, but also the top layer of the earth. Biological material can be completely different: horse manure, chicken droppings, tree bark, straw, sawdust and other options. Horse manure is the best option.The fact is that it can warm up to 70 degrees and keep that temperature for about three months. Due to the presence of polycarbonate, such a system very effectively heats the air and the layer of the earth, which is important for the growth of plants and their fruits, for example, cucumbers. In addition, it is possible to create a special material for efficient heating of a greenhouse with your own hands. To do this, it is necessary to lay the following layers: finely chopped straw, lime saltpeter on top. All these layers must be watered with hot water, tamped tightly, and a layer of earth should be poured on top. The result is a biofuel that effectively heats the ground and air in the greenhouse in winter. The main thing - .

Technical heating of greenhouses. ... In such conditions, the previous two methods of heating a polycarbonate greenhouse will not be a good solution. A winter greenhouse, of course, has some capabilities, but when it is severe frost outside, it is quite difficult to maintain high temperatures inside the greenhouse. This is where technical options for heating systems come to the rescue. There is more than one method for technical heating of a winter greenhouse:

Electric option. If we consider the way in which conventional heaters with a built-in fan will be used, then we can immediately discard this idea. This will consume a lot of energy, and the effect will not turn out to be impressive. For the electrical system to be efficient, to warm the air well in winter indoors, it is necessary to use cables and heating elements. They can be laid not along the perimeter of the greenhouse, but in the ground at a depth of about 40 cm. This heating method is very effective, but you must be prepared for the fact that it will cost a lot in winter;
Water heating method. This is the same method used in residential buildings. It is quite effective, popular and actively used for heating a winter greenhouse. ... In addition, the installation of such systems is easily done with your own hands. This will require a boiler and piping systems. Pipes can be laid both along the perimeter of the greenhouse, and directly in the ground, on a specially created drainage substrate. Gas, electricity, coal and firewood can be used as fuel for the boiler to heat the water. The fuel is selected depending on the selected type of boiler. It is important to carry out heating of large polycarbonate greenhouses in this way. The costs will be justified, and the system will warm up both the air and the ground well in winter to the required temperatures;
Greenhouse infrared heating systems. This method is considered the last word in the technological process. To achieve the goal, you can use various types of infrared radiation devices: screens, panels, and lamps. Their advantage lies in the fact that they heat the soil to the required temperatures, and not the air at all. Such methods of heating a polycarbonate greenhouse are energy-efficient. ;
Stove heating. Yes, this option is also possible. This is one of the ancient heating methods used in some villages. This is a laborious process and, in truth, ineffective. Such heating of greenhouses should not be left unattended and constantly put firewood so that the temperature does not drop below the prescribed limit.

The listed methods of a polycarbonate greenhouse heating system can be created with your own efforts and with your own hands. ... Proper heating of the greenhouse is the key to an excellent harvest that will delight your table in the winter. A winter greenhouse is a great opportunity to fulfill your desires and bring the long-awaited spring a little closer.
