(It had to happen when it's cold outside....)
So I've had an UFH heating for 7 years, all been fine. But last night, I noticed that the rooms were chilly and no heat coming through the floor. The thermostats were on, the signals (from all 4 zones) were being sent to the wiring centre ok. I had hot water coming through the taps.
Checked the boiler, and the pressure was very low, so I re-pressurised. Pressure is still fine this morning.
I checked the UFH wiring centre, and the lights are on, but noticed that one light does NOT come on - the one for Hot Water (HW in the photo below).
1) Could it be an electrical/wiring issue with the wiring centre?
2) Could it be a pump issue?
3) With the boiler having lost pressure, I don't know whether that would cause a lack of water/pressure in the UFH system, and so I would need to refill it?
Any help or suggestions would be much appreciated! I tried calling the Heatmiser helpline, but after 10 minutes on hold i was still #14 in the queue.....
