Many owners of suburban areas, for sure, would not have given up the possibility of harvesting all year round. Unfortunately, in most Russian regions the climate is such that this desire is as utopian. However, the arrangement of reliable greenhouses equipped with productive heating system may be the solution to this issue. Recently, the most commonly considered gas heating greenhouses, due to the advent of modern technology on the market - IR radiators and heat convectors guns.
The classic version
The traditional approach to the use of gas in order to ensure optimal microclimate greenhouses intended to create a thermal path whose base - gas boiler. This method is effective and reliable, but for a small private greenhouse fit is not too good, it is imposing financial investments, it is necessary to form complex wiring pipes, install valves for fine-tuning and adjustments functioning. Everything else, such a method involves heating the gas receiving numerous inquiries and permits Equipment belongs to the category of potentially dangerous, and therefore required the approval of the supervisory authorities.
As a result, this scheme is relevant only in the case when it comes to large commercial greenhouse area of several hundred square meters. Then we can talk about the justification of all investments, they quickly compensated. Creating a separate heat path for a small farm structure is appropriate only in the case, if the owners use the gas boiler for heating the main cottage, there is the opportunity to branch to greenhouse.
Traditional mobile equipment
Heating private greenhouse gas is more economical in the event that the home use, portable device.
In today's market presents the following modifications:
- Heater open with burners. The design assumes that the thermostat, the main and auxiliary burner device. The applied and the balloon, and a power source line. flame heats the air that is naturally begins to climb to the roof, then uniformly deposited, increasing the temperature in the surface area, that is exactly where located plants. The main disadvantage of methods is that the combustion process lowers the oxygen content of the air, and this is detrimental to the crop. To compensate for this phenomenon can be equipped with rather simple ventilation system. Surrounding the heater punches a hole in the wall of a diameter at least 5 centimeters. The aperture of the PVC pipe is inserted. For protection against insects and rodents it is recommended to install a metal net with fine mesh.
- Heating with gas convector. Installation of this technique is done on the walls, the design implies a hermetic combustion chamber on the basis of steel or cast iron. Inside the chamber is a main burner and an indoor heat exchange circuit. Operation is controlled by automatics, main balloon or gas enters the main burner, whereby there is an internal heating housing. The heat exchange circuit transfers energy inside the greenhouse. Compared to a conventional open heater, the device independently carries out air inlet and outlet of the combustion products, ie agricultural facilities falls oxygen level, it eliminated the need for additional ventilation arrangement pipes. The device automatically adjusts the temperature according to the set values, safety is guaranteed by a locking mechanism that cuts off fuel supply to the situation with the downs of traction or pressure. Such a heating device is sometimes provided with an additional fan. Modernization improves the efficiency of the air in the greenhouse warms up much faster, but there is dependence on electricity.
modern approach
Infrared heating burners It is considered the most advanced, gentle and cost-effective manner. The operating principle of infrared techniques based on electromagnetic radiation produced by the heating elements is heated in the combustion process.

Devices are divided into two groups:
- "Dark" units are equipped with tubular heating elements, the maximum temperature of which is 600 degrees;
- "Bright" grid device equipped with heating elements or a ceramic plate, whose temperature is able to exceed 600 degrees.
Do not forget read the pictures, For heating greenhouses with their own hands.
The reason for this division into groups is the ability to "light" burners produce light of the visible spectrum, the type of ordinary incandescent lamps. However, 60 percent of the total heat flux falls on the infrared radiation.
If we consider the design features, the "dark" devices based on the elongate member in one direction, due to the tubular shape of the heating element. Additionally mounted pipe for discharging combustion products. "Bright" IR analogs have its own flue, the combustion products are emitted inside the greenhouse, and therefore must be additionally equipped with a duct structure.
The advantage of technology, operating in the infrared spectrum, is that with its help it is easy to organize local heating zone, to prevent the temperature in the areas where the most heat-loving grow culture. Practice shows that the maximum effective device during seed germination, also require an abundance of thermal energy.
Output
Thus, the heating of private greenhouse gas gun - is not the only version of events when using this type of fuel. A sound approach to the development of the scheme, taking into account all possible factors, attention to modern devices - all of which help to establish a system that will not have weaknesses. Given the fact that the gas in Russia is significantly cheaper than electricity or solid fuel, well-equipped scheme will pay for itself in a couple of seasons.
