if a combi doesnt fullfilla 35 oc temp rise what wold be the cause? poor gas pressure and poor inlet mains water pressure? any others?

hi. just wondering when fault finding on a boiler ( in general)where ch or hw is on off on off and not requiring reset then overheating or flame detection issues not the problem as the boiler would go require resetting if any of these two occurred so would be looking at other issues causing on...

hello. could anyone explain the advantages and disadvantages of zero govenors? any safety issues which have arisen from these . also how do you test their safety. i run the boiler to max then plug out the fan. thats what valliant chap said anyhow!! thaNKS

hi. great tips on previous posts. i seem to coming across alot of regular biolers on y and s plans which take an lifetime for the boiler to fire up. i noticed this with profiles. some take 4 mins before the fan kicks in.what would cause this delay. motorized valve moving very slow to make...

thanks .come to think of it there was major water mains works outside the house for weeks!!!

gas rate , flow rate fine. u misunderstand. the boiler works perfectly fine when dhw is run but when the cold tap is run at the same time as dhw the boiler stops.!!!! how can running a cold tap stop the boiler in dhw mode. ??this is weird !!!!!!!!. i can only think that once the cold mains is...

attended to a worcester 24 rsf combi today. hot water runs fine but when any cold tap is run in the house the boiler stops!!!!! im totally baffled by this? has anyone had any experience of this. weird!!!!

ta. is it common for water pressure gauges not to respond to refill. i guess on the greenstar 25cdi theres no low water pressure switch like the puma but rather the heat exchanger is protected via high limit stat.

no leaks. prv fine. only a 3 rad flat

hi. atttend to a worcester greendstar 25 cdi . e9 code flashed up.system pressure gauge read zero. refilled via charging link and could hear water flowing but no movement in gauge. anyway ordered a new pressure gauge. apart from faulty pressure gauge not responding to refill or blocked feed...

what a great site. just completed my acs and landed a job servicing. just want to be sure on carbon monoxides causes on boilers--blocked flue, restricted ventialation, over/under gasssed applainces caused by wrong pipework, incorrect gas meter regulator, incorrect burner pressure setting on...
