I've a Greenstar CDi boiler, about 18 months old.
The last few mornings I've woken to a cold house - the wireless thermostat is displaying a flame, so it is calling for heat but the heating is not coming on.
Hot water is working absolutely fine and gas supply is turned on.
The first morning I turned the thermostat off and then on, this seemed to kick start things and the heating was working when I got back from work.
This morning however, I turned the thermostat off and on, heating kicked in for 5 minutes then went off. Subsequent resets didn't get it working again either.
I've checked the pressure gauge on the boiler and this seems fine - 1.5 bar, the gas supply is definitely on, and there is no battery warning light on the thermostat.......
My boiler is in my garage, thermostat in the hall.
Any help / advice gratefully received!!
