Good Morning,
With the recent heatwave we are experiencing, i've come to realise that the radiators on my 1st floor (seperate zone), are warm/hot even when the heating side of the system is set to off via programmer.
I think i've pinned it down to the rads are getting warm when the HWT is demanding and getting heat.
The setup is:
Boiler - Intergas HRE24
three zones off it - 1: HWT
2: Upstairs rads
3: ground floor UFH manifold.
I've made sure both zones 2 and 3 are not open (zone valves not energized) while the hot water is on, but still getting warm on the rads.
My thinking is that the pump in the boiler is pushing the water through fast enough/with enough force to push the mechanical ball on valves 2 and 3. the manifold being closed is then not allowing any water to flow in the underfloor so its all being diverted to upstairs heaters.
Anyway to test this without getting someone out?
