Hi,
I would appreciate some advice. We have a Biasi Inovia 35C combi boiler which powers our central heating and hot water (there is no cylinder).
Woke up this morning to find that all the radiators are cold. Hot water is fine. Tried various things (top up the water to increase the pressure to 2.8 PSI, fiddle with thermostat, press all the buttons) nothing worked.
On the LCD, the central heating water temperature is showing to be 75 degrees (that's what it's set at) and the flame comes on intermittently. But the radiators are cold. It shows a flashing radiator to signify demand for heating. It appears to be firing up fine and heating the water, but then cutting out when the required temperature is reached.
I eventually turned the whole thing off from the main switch, waited a few minutes, then turned it on again and it came back to life - radiators hot. But it lasted only for about half an hour and then slowly all the radiators went cold again. Same thing repeated during the day - works for a while then needs to be switched off for a few moments from the main switch.
Surprisingly the only radiator that consistently stays hot is the bathroom radiator.
The boiler seems to be working but my feeling is that the pump can't pump the hot water around the system. I don't know if this is a common / recognised problem? I would have thought that if a pump fails it just dies rather than getting weak.
Does that make sense / what do you think might be wrong?
Thanks in advance!
