Hi a couple of months back, I installed UFH in my conservatory, I fitted the manifold and pressurised it, and then screeded, I have now come to properly connect it up to my main radiator feeds, and realised I may have a problem...
I have a room thermostat in the hall, which wirelessly connects to my combi (Worcester Bosch 35CDii), I now also have a room thermostat in the conservatory, which opens the UFH circuits, and kicks the pump in for that.
It's occured to me, that there could be a situation, where the thermostat is requesting heat, and switching on the pump, but the boiler is not on, because the hall thermost says the house temp is fine.
Hope I am making sense here...
Now I am wondering, does combis generally have flow sense, like on the taps, when water flows, it kicks the boiler into heating? As that may fix my problem, so the UFH pump will start circulating, and kick the boiler into life...
I suppose my other option, is to get another wireless transmitter and pair that up with the boiler, and fire that when the UFH thermost box lights up.
Can someone enlighten me? Thanks.
