need a bit more info on the type,make,model of boiler.

f its the condensing variety,i have had it before where there is a small leak on the condensate trap and the way it works is to short to earth and this will lock out the boiler. to prove if this is the fault you could remove the lead from the trap (NO VOLTAGE) tape it up making sure it doesn't...

your probably right actually olski. what was i thinking!

mmm! don't forget to turn it right off tough. you may get a nasty shock if it gets cold over night!!!

DEFFINATLEY DO NOT GET ANOTHER ARISTON. they should stick to making fridges.not boilers. I repair boilers day in day out and i don't go to many worcester greenstars or vaillant ecomx's. and the reason why your installer won't want to install one of theses is 'cause they are twice as much. please...

sounds like system gassing due to its obvious age. if lock/shield valve open already (other side to TRV) then you could have a blockage in system, this would explain the air. could also be ingressing air back down open vent if cold feed blocked. Is the CH water Black? if so this could also point...

sometimes only two are used. just like a switch. It probably will be the pump overun stat. it will be stuck and permanantly in the closed position. You will need a heating engineer to change it for you. The way to prove this is to check the resistance across the two terminals. if the resistance...

usual suspect for fuse blowing are pumps,fans,or sometimes different stats on boilers. depending which one it is

prof,plumb is absolutely correct. although it is not something we should be telling non-corgi registered people. I just usually say 'yes' you do have to be corgi registered. saves all the hassel Besides regs regarding where to and not to run gas pipe are not known by your ordinary DIY enthusiast...

Hi. If you let the central heating go cold. I mean realy cold. Turn on the tap without central heating on. feel the CH flow pipe on the boiler. if this gets hot then the diverter valve will want swopping as the hot water will be passing down the heating circuit. This will be why the burner...

The pipe to the expansion vessell WILL be blocked..always is. but the will not cure the rising temp problem. If the pressure needle judders this means the temp. is too high. Things to cause this are pump problems or system blockage. The fact is that its a celtic. In the top 3 worst boilers of...

Hi to be honest you should'nt have even got a ferroli. But seen as though you have it. It probably is the board,but i personally would'nt go throwing good money after bad on the piece of pooh. get something good like a worcester bosch or vailant. By the way i am talking with a great deal of...

any local merchant should be able to provide you with a tool to switch off the supply. Failing that, unfortunatly you will have to phone the water board and if there anything like yorkshire water then don't expect them anytime soon

Hi. I am a BG engineer and have just looked on my lap top and what he has told about a NEW fan been available is correct. And about the micro bore been aparling prof.plumb got it just about right,but to save you re-piping the system you could look at converting the system in to a sealed system...

When you say you have a mega flow system that runs your hot water is it directly heated by imersions or do you have a motorise valve which opens and closes depepnding on the demand from the clock and cylinder stat. Also it is very possible that the fan in the baxi solo blew the fuse in the...
