Greenhouse heating is a very important issue not only for agricultural producers, but also for ordinary summer residents. After all, they grow not only vegetables, the price of which is growing almost every day, but also some ornamental plants, flowers, herbs, which are in demand in the winter.

In spring and summer, due to natural conditions, different crops can be grown in the greenhouse without additional heat. And in autumn and winter, when both the soil and the air are cold, it is very difficult to grow something. That is why heating is needed for greenhouses.

There are many different ways to heat them. One of the most common and cheapest is solar heating of the greenhouse. It does not require the cost of purchasing equipment. All that is needed is just to put the greenhouse in the place where there is the most sunlight, and then cover it with ordinary glass. The disadvantage of such heating is that it cannot be used in the cold season, since at night the temperature of the air and soil drops, which adversely affects the life of greenhouse plants.

The most commonly used electrical equipment for greenhouses. itthe most popular heaters, of which there are a lot of types. Here are some of them:

• Convectors - devices that are equipped with heating coils. The greenhouse heats up almost evenly, but their minus is that the soil does not warm up enough.
• Heaters are heat fans that can be easily carried. Compact and inexpensive. Warm air is distributed evenly. Most heaters have a thermostat with which you can set the desired microclimate. Its disadvantage is that it dries the air.



• Cable heating is an inexpensive and very effective way of warming. Along the perimeter of the beds, a cable and tapes of a certain power are laid in the ground. The main thing before installation is to choose such a temperature mode so that the root system does not overheat.



• Water heating refers to electric, as the water in the system is heated by electrics. This is a universal option that can simultaneously heat both the air and the ground. It also has disadvantages: installation should be done only by qualified specialists, high cost, it is necessary to constantly monitor the operation of the device.

They also use a professional system - air heating of greenhouses. It is installed during the assembly of the structure in the base of the foundation, on the supporting structure, and only specialists should monitor this. Warm air is distributed to the middle and upper part of the greenhouse space so that there are no burns of plants.

There is also gas heating using gas heaters. Their principle of operation is that to heat the greenhouse, carbon dioxide and steam enter the air, which is necessary for plants. But there can also be burning of air, and burning out of oxygen. It is very dangerous for plants. To avoid this, ventilation systems and air supply systems must work.

If the greenhouse is small, then it is not necessary to connect to the general gas pipeline network, you can take a couple of gas cylinders, which will last for a long time.

A good and very economical option is stove heating of greenhouses. Here you can use different energy sources: firewood, coal, gas. The disadvantage of such a system is that the walls of the furnace are very hot. There are safer options, for example, heating greenhouses with buleryan. Such a boiler does not overheat, and its system is reliable and easy to operate.

When installing equipment for greenhouses, it is important to observe safety rules and follow the instructions.
