oil combi DHW problem
May 8th, 2005, 12:12pm  
Hi, I've had an oil-fired combi (worcester heatslave12/14) installed 2 years. Recently when the hot water only setting is selected this also heats up all the rads even though the room thermotat is set to 0. Any ideas ?

check your motorised/diverter valves, sounds like the one "blocking off" the heating rads is stuck open.  Could also be faulty stat keeping it open, amongst other things. Start with the motorised valves...
