Buffer ball mixing valve

Hello
Ah you have a pellet boiler ... a heat pump is practically useless ... Do you have a buffer tank?
A+

in my case if, it can be useful, in mid season a cap would be useful because I have to turn on my boiler just for 1 hour, so a small cap would be the solution finally I think

another question the check valve you put it or exactly?

[ulyssesourd]

in a place where the direction of water circulation must not be reversed by the thrust of a circulator ... For example a connection by a tee: we put the valves at the places where the water is pushed by circulators, comes from 2 different places to go to a specific place, but we do not put a non-return valve if the water is "sucked" from 2 different places. It is logic that must be studied ...

and for recycling water return from wood boiler what do you put?
