No need for 2 inlets and 2 outlets of the tank and all these valves ... because for optimum operation of your boiler while heating AND recharging your 1000L tank you need: an inlet to the tank with a JUNCTION towards the circulator / 3 ways, and likewise an exit of the balloon towards the heat ...

indeed nothing is pilot. For the 3-way valve, 5 seems a good value to us. We are not used to being hot in the house so we are very well. On the other hand, if a room thermostat controls circulator N ° 2 and that 1 is stopped, will the water circulate all the same? In addition ...

I had made a quote boiler plate: 25000 € before tax credit installation included.

so long live the wood log boiler

yes I see the system that looks quite good indeed. This circulator is the one that will be connected to your boiler. Since you will have a balloon, think of taking another circulator which will work permanently on the main circuit. For all the piping my brother used iron tubes of ...

My brother had been coming to work on Fridays since July and there all the details were settled. Well done and happy that it is also running! It will be joules that the oil tankers will not have ...
