Hi All,
Need a bit of advice, I have a underfloor heating system going in, the set up is: heat is coming from a thermal store cylinder (open vented/ no pressure), UFH side is pressurized (due to high top floor). It needs a pump on the primary side (un pressured) to supply a ‘heat exchanger in the middle, which supplies the UFH side (pressurized).
Now, when I wire up the zone pump (of which there are 4) to come on when heat is called for, how do I wire up the primary pump to come on the feed the heat exchanger?
If there was only one pump either side it would be no probs, however with 4 manifolds each with a pump this is proving difficult. I need to start the primary pump independently form any of the 4 zone areas, otherwise all 4 zone pumps would run.
Anyone got a solution, apart from run away.
Regards
