The greenhouse without heating gives the chance to receive harvest only during the short warm period of year. In heated it is possible to gain several times bigger access of products. For successful cultivation of plants certain temperature condition is necessary. Minimum temperature for development of vegetables - 18 °C. It can be reached, having arranged heating services in the greenhouse. The most widespread is water. How it is correct to make the greenhouse with such type of heating?
It is required to you
- Material for construction of the greenhouse. Material for heating services: pipes with sections of batteries for water, hot-water boiler, expansion tank.
Instruction
1. Choose the necessary material for the greenhouse device, proceeding from its area and your opportunities. The greatest ability to keep heat have double-glazed greenhouses or made of polycarbonate.
2. Choose boiler model depending on type of fuel available to you (firewood, coal, peat, gas). Install in the platform of the greenhouse or in the certain room the boiler nearby.
3. Mount pipe system. From the heat carrier the main pipe will pass under roof ridge with small bias by the end of the greenhouse. There this pipe will be separated into 4 pieces with a diameter of 50 mm. These pipes will pass under each side rack. Along walls of the greenhouse arrange sections of the batteries which are powered from the main pipe under the fad.
4. Bring out of the main pipe chippers - 2 or 3 pipes on each party of roof of the greenhouse. They will heat glass and not to allow snow to accumulate on roof. On each section of the battery and on separate pipes establish valves for temperature control.
5. Connect all pipes returning to boiler to one comb. They one pipe with a diameter of 75 mm will enter heating system.
6. Over boiler it is necessary to mount expansion tank. It has to be connected to the highest part of feed pipe under the greenhouse fad. Fill system with water or special nonfreezing liquid.
