I have a Keston 80 boiler that fires CH and HW. Burner fires when either HW and CH are called for, but water does not heat.
CH gets up to temp fine although rads do seem excessively hot, and the burner seems to switch itself off and on again every couple of minutes whether or not the temperature is up to room stat level. Similar switching on and off for HW, though the water doesn't get hot at all!
I hate the bloody Keston but stuck with it for now!
Advice gratefully received! Cheers all.
