My UK Nest is having a problem with the heating not working.
My nest thermostat seems to have stopped firing my boiler for heating in both schedule or manual mode - although the thermostat seems to be working showing the set temperature. The thermostat temperature shows up fine on both phone and yeh app - but yeh boiler does not seem to start .
The hot water is working fine and as per the set nest schedule.
Any suggestions on what the issue is and if I can fix it?
Please help as I have my elderly father with me and we need the heating to start working ASAP.
