A year-round greenhouse with efficient heating - what does it look like?

If you need a year-round greenhouse with heating for your own needs, it makes sense to build it yourself. The best option for home use is a greenhouse with a size of 4 * 8 meters and a height of 2.5 meters. 16mm polycarbonate is best suited for a winter greenhouse as a heat-resistant coating. In this case, for heating such a greenhouse in a year-round mode, a boiler room of 10 kW is required. The calculations are made taking into account that the required room temperature should be 15 degrees Celsius in winter, with a minimum temperature of -25 C.

If you want to limit yourself to the spring-autumn growing season, you will need a boiler room with a capacity of 4.6 kW (minimum temperature -5 C). This is not at all burdensome for the average Ukrainian family. What should be foreseen when building a greenhouse?

Ground battery device

The general principles for the construction of a year-round greenhouse space are in many ways similar to the deployment of heating in residential premises. It is important to provide not only insulation of walls and roofs, but also of the soil. Winter greenhouses it is customary to do on a pre-insulated base. You can make an underfloor heating with thermal insulation, but our recommendation is to use an insulating backfill under the ground.

Depending on the goals, for these purposes, the following may be suitable:

• crushed stone;
• broken brick;
• expanded clay.

The most important remains rock and ceramics, which accumulate heat. Vermiculite and perlite can be used as warm mineral filling. The general principle is that in order to create a heat-accumulating cushion, a layer of material with the appropriate qualities is filled in. Pipes with a high-temperature coolant can pass through it. In this case, heating costs are reduced.

heating equipment

When selecting heating equipment for a year-round greenhouse with heating, pellet boilers are almost always chosen. Or a conventional solid fuel boiler with a pellet burner. Heating in this case costs about UAH 0.464. (2020), which is two times cheaper than using gas.

A ground accumulator with a high-temperature circuit is an analogue of underfloor heating with a heat retention function. This significantly saves fuel consumption and further reduces heating costs.

The air in greenhouses is heated with the function of supporting air recirculation, that is, using a fan heater operating on the water circuit.

Additionally you will need:

• solid fuel boiler;
• pellet burner;
• fuel hopper.

What is the advantage of FOCUS pellet heating equipment:

• the presence of microprogram control, with which you can implement the "smart" greenhouse function;
• complete supply of everything you need;
• relatively low prices.
