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 grows almost every day, but also some ornamental plants, flowers, greens, which is 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 ground and the air are cold, it is very difficult to grow something. Therefore, heating is necessary 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, because 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. These are the most popular heaters, of which there are a lot of types. Here is some of them:
- Convectors are devices that are equipped with heating spirals. The greenhouse heats up almost evenly, but their minus is that the soil is not warming up enough.
- Heaters are heat fans that are easy to carry. Compact and inexpensive. Warm air is distributed evenly. Most heaters have a thermostat, with which you can configure the necessary microclimate. Its drawback is that it dries the air.
- Cable heating is an inexpensive and very effective way of insulation. Along the perimeter of the beds, cables and tapes of a certain power are laid in the ground. The main thing before installation is to choose 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 air and soil. It has also 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 in the middle and upper part of the space of the greenhouse so that there are no plant burns.
There is gas heating with gas heaters. Their principle of operation is that for heating the greenhouse carbon dioxide and steam get into the air, which is necessary for plants. But there may be burning of air, and the burning of oxygen. For plants, this is very dangerous. To avoid this, ventilation systems and air supply systems must work.
If the premises of the greenhouse are small, then it is not necessary to connect to the general network of the gas pipeline, you can take a couple of gas cylinders, which will last 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 become very hot. There are safer options, for example, heating greenhouses with buleryanom. Such a boiler does not overheat, and its system is reliable and easy to operate.
When installing equipment for greenhouses, it is important to follow safety rules and follow instructions.
