Explanations

It is a fitting 3 energies: solar, wood and electric supplement.

The solar-timber solution, in our opinion, the best compromise éconologiquement speaking: near fuel (wood), long life (maintenance inexpensive) and low power consumption.

These criteria are the weak points of geothermal energy and other air-to-water or air-to-air heat pumps which are very "fashionable", commercially speaking ...

    • There 2 solar circuits completely independent of each other: one for hot water and for heating.

 

    • 8 the solar panels are distributed this way: 2 6 for ECS and for heating.

 

    • The ECS circuit has an electric supplement in case of lack of sun, it consists of 2 balls in series as shown in this picture:

    • The food is heated floors in bi-energy: solar and / or wood.

 

    • Wood circuit is connected in parallel solar circuit: we can therefore use either one or the other, or simultaneously 2, since each circuit has its own pump.

 

    • The buffering of the solar energy or the calories of the wood is done in a buffer tank of 1000L studied "homemade". It is an isolated "cubi" in which I put a homemade copper heat exchanger 22mm copper tube of which here is a picture:

      This is a photograph of the plant in the state, soon I'll optimize it a little while to make it more presentable. Here is what it was like the tank solar.

 

    • The finish temperature of the floor heating is controlled by a single thermostatic valve (set to 24 ° C)

 

    • The circulator floor heating is controlled by a room thermostat present in the living room.

 

    • 2 the check valves allow not to heat the solar collectors with the wood stove and vice versa.

 

    • We have one electrical addition: an electric towel in the bathroom.
