Often a flat solar collector is used for heating.
For its construction you will need:
- metal frame;
- solid bottom;
- thermal insulation layer;
- black solar radiation absorber layer (adsorber);
- transparent cover - plastic, glass;
- tubes for liquid (copper, aluminum).
The design must be equipped with inlet and outlet pipes and a pump for efficient fluid circulation.
You can install a flat collector at any angle, a prerequisite is to clean it from snow and dust. It is especially good for warm climates.
In the cold season, low efficiency and high heat losses are observed. Which casts doubt on the use of this solar system alone for full-fledged heating. It would be optimal to use a flat solar installation together with gas, electric or solid fuel type of heating.
