any help would be appreciated?
i have a Ravenheat 100ET combi boiler - brand new & fitted 4 months ago by a CORGI guy - central heating works fine and DHW is great whilst CH is being called for. The problem is that we get NO DHW when CH is NOT being called for or also when boiler is switched to Summer setting. Ravenheat wont talk to me as I'm not the CORGI installer who fitted it!!!
anyone got any ideas at all?
