I've got a Halstead Quattro boiler.
When switched on I can hear the boiler go on standby.
The problem I have is that the it will only heat up, if i physically tap the bottom of the boiler. I lightly hit the bottom of the console where the dials/lights/nobs are hear a couple of clicks...
hey,
I've moved into a house recently and been having problems with the boiler (Halstead Quattro).
The heating has been set on the timer and usually works fine.
Occasionally the central heating stops (cold) or comes on but at a low temperature. When this happens there is no sound...
