Re: Solar thermal heating

It's called a 3 or 4-way valve and actually allows less hot water from the return to be mixed with the water coming directly from the hot source; a simple graduated lever allows you to adjust the desired temperature by varying the respective flows... Sorry, I read but didn't understand...

Re: Solar thermal heating

All this seems very complicated and expensive to me... Why not the heat pump, especially with underfloor heating. At the top of France with radiators, heated surface: 150 m², I manage to consume less than 1500 kWh in 2022. The same in 2021. In addition, only 2 - 3 hours in the evening, I burn one to 2 logs...
