He was possibly meaning a "Plume diversion Flue" as is fitted to some condensing chb's. Not sure if Vokera do them though. Seen them on Worcesters boiler installs. Unless there are any Vokera eng's on here I would suggest contacting Vokera direct for an answer....................

Small problem has developed on my Vokera 735. Fault on DHW only. After running for 30 seconds it sounds like a train, a repetitive noise. Thinking either non return valve not sitting at plate HX or overheating but it's only 18months old, has a magnaclean fitted and was all flushed out when...

Cheers....thought I would have got a bit more for the Aluminium but it free money so to speak.

Does anyone know what the going rate at the moment for opper/Aluminium?? I have got 100kg of used copper and 10kg of aluminium cans to be exchanged. Cheers

Yeah, I do work for them. They do get a bad reputation from certain people but as a lot of people have said, there are good and bad engineers everywhere. The prices are a lot better, us engineers were complaining about the prices for years, they have now either took notice or their business...

I had thi problem on a job last week. The leak from the o-ring usually gets into the mororised valve. Usually knackers them but on this occasionthe fault was on dhw demand the motor was moving in/out/in/out constantly causing hot/cold water delivery. New motorised valve fitted problem...

RE: the major supplier who is supplying 0% on new boilers Quoted a customer £2020 to replace a response 80 with a greenstar 24, upgrade gas pipe/sort electrics (no earthing,stats wired up incorrectly etc) When you cosider the 0% for 12 months it is a pretty decent price. Local guys were...

What's the chances the strike will be called off???? Happened the last time................

Surely when on CH only, flow to cylnder shut. Circulation around rads crap though.....

No, problem more on CH. Sometimes o/heat pops when heating on only. It is certainly a return issue, when some of the rads are trying to heat the flow is roasting, return freezing.....NO whooshing noise when etc when it does start to heat...

Was changed to a sealed sytem 3years ago so think this is ruled out......

Hooked upto a system the other day and it wouldn't circulate??? Sealed system,Yplan, system chb. GLoworm Ultimate 22mm pipe to pump/valve before it goes undergrground into 15mm. The problem is poor circulation initially. The boiler cycles off before there is any heat to the rads. Heat gets...

No your stuck with the old fire i'm afraid. There may be a couple of options but they will not be of a modern design

injector partially blocked, get thermocouple changed at the same time. \£99 with British gas or a little less with a local. lot of other checks to do as it's a BBF

expansion vessel pipe choked????? depends on boiler type

Wasn't to sure if this chb had one as bad as the vokera o/heats that fail all the time.....but yeah, could be that too/also

Thermocouple is knackered. It would have been ok when lit but twhen it cools, if faulty, it doesn't expand again to keep the pilot lit. RGI needed, £10 part though so not a big cost......

Sometimes achievable, sometimes not. Same old story. New latop/tracker and performance measures is just a way or getting rid of poor performing engineers I think. Quite a few will be under the performance programme or whatever they are calling it once the 3months figures are calculated...

Let me get this right. I have a momentary action button fitted, I need to fit a relay to keep the power latched on when pressed. I need ANOTHER button to turn it off??

Latching relay, that's what the RS tech help were advising but they didn't call me back with an option SO what kind of "LATCHING RELAY" would suit me?? I'm switching 240vac. Thanks very much for all your help. Graham
