Thanks for the quick replies .. If it is ignition and therefore gas related ...then I would certainly get a heating engineer to look at it .. Its odd that the ignition works ...the boiler starts fully .. hot water is circulating around the rads for a good few minutes ....before it...

Hi friends .. I hope someone can help and advise me ... This boiler was fitted by me ...then checked and commisioned correctly by a proffesional over perhaps 10 years ago ... It has run absolutely trouble free for all those years ...but I suspect the recent cold spell had it working overtime...

Thanks a lot for the help .. ..as usual ..very speedy and most useful info.. Fault traced to faulty switch on the motorised HW valve ... It physically moves (motor ok) but the microswitch was permanently open circuit ...hence no power to start the boiler in HW mode.. cheers :wink: Keith

Thanks for the speedy reply Kev ..and pointing me to the correct plan.. rgds Keith

Hi friends .. Im currently spending the weekend with my brother who's recent house purchase also included what appears to be a gravity fed single loop boiler system ..and being unfamilliar with this setup ..I figured you guys might be able to point me in the right direction.. It appears the...

Many thanks for the explanation croydoncorgi ... That makes sense ...though I have no way to check the precharge pressure on the air side of the diaphragm within the vessel .. The vessel has never been tampered with ...so unless faulty in some way .. I guess it is still set as it was at...

Thanks for that Kev ... I can only assume then that the CH system ...pipes rads etc ...are absorbing the pressure without untilising the expansion vessel to any great degree .. Pipework is mostly 22mm with short 15mm spurs to rads ... Rads total 7 in all .. thanks for letting me bend your...

Thanks for the reply Chris .. Sorry to appear thick but don't understand the term precharge ...can you perhaps explain in laymans terms .. very much appreciated rgds Keith

Thanks for the reply Kev My system is pressurised at 1 bar when cold and rises to approx 1.5 when the ch is in use .. is this within acceptable limits ? rgds Keith

Hi friends .. Still playing nice with my overactive Ariston c0mbi ...and still trying to determine the nature of my fault if it actually exists.. During my investigations I found that even after several hours of use the expansion vessel and the pipe connecting it to the boiler remain stone...

Fair enough Chris ...I guess thats one for the experts then ... Pity ...I was hoping I could have saved a few bob :roll: Thanks for the reply m8. rgds Keith

Hi Bahco ... I should have clarifed my origional statemet re - the rads The bathroom rad/towelrail has no trv fitted and is permanently open so acts as a permanent return .. I'm assuming that would be adequate ? rgds Keith

Many thanks for taking the time to reply Chris .. I'll dig out the manual and check out your suggestions re anticycling. btw .. Not related to my immediate problem but figured it can't hurt to ask .. How does DIY stand regarding cleaning out the the boiler with a hoover and brush .. Is it a...

Hi again ... I hope no one minds me persuing this problem ...but in light of the snow and the general drop in temperature ...my Ariston has been flogging itself to death over the weekend.. Im still convinced I have a problem in the making ... and over the last couple of days I have heard a...

Thanks for replying Chris... I suspect I should be ok regarding the mounting of the boiler ..as I did have some help with the actual drilling and hanging of the boiler from a m8 who at the time was a regd plumber.. Sadly he isn't around to ask about my current problem as he's moved on to...
