thanks I would like to get a battery one ideally, will search for honeywell one's!!

yep, all seems ok now! although I have been using the pump when h/w was on. Funny it seized/stiffened all of a sudden

the boiler stat does adjust the temeprature but the oheat still trips!! the pump seems very stiff, I freed it with a screwdriver, and tested the resistance of the windings which were 167 ohms. he system is full of water and I checked for a blocked cold feed and all ok. I'll see how this goes...

Whilst I think of this! Can anyone recommend a good quality reliable CO detector, a battery one? I have an old spot card one but I'd like a good quality reliable one to fit near my boiler. Thanks for any help

I've tried the boiler stat on all different temperature settings but the temeprature must get so hot due to a circulation problem that it still trips the overheat

when you say turning the heat down, do you mean on the new condensing typer boilers? When my one gets hot it just turns off and not down

Thanks for your reply I know it will bet hotter due to circvulation problems and hence the flow increasing in temperature. The reason I ask is I have an old boiler, Glowworm Fuelsaver, and the pilot goes out after a while when the boiler is on, the interrupter kicks in (overheat...

Hello, a quick query I'd like to ask for help with if I may, please don't laugh as it is probably simple but I just cannot work it out :oops: = If a boiler's heat exchanger (normal boiler not combi) is blocked with sludge etc why would the flow get really hot and the return stay cool? I know...
