the Gas boiler light flares up when the CH is switched on (as it should) but doesn't when the hot water tap is turned on. its a ravenheat Combi boiler.
we've had nothing added or changed to the system. the pressure did go below 1 but i turned it back up again.
pls help
p.s. i know very little about boilers.
