Back again One more visit, still no pilot light staying on. Engineer checked out system and could not identify any root cause, so cleaned boiler and of course no difference. Left hand side of the boiler much hotter than right (as you look at it mounted on wall) Have not got temp...

Tony You mention Until the temperature differentials have been measured What exactly do you mean by this, inward and outward temp of flow into the boiler? How should this be measured. Sorry for so many basic questions but I you can guess I ain't an engineer. Your right so far I've...

I do understand the problem, but there is often more than one way to solve the problem. There are many trees on my property and suspect drain is surrounded by many many roots some of which have found a way through a join and have blocked the drain. I don't want to cut down all the trees which...

If sludge is a problem and slow flow would I not expect to see radiators not heating up very well? They do get very hot and distribution is OK (all radiators are heating) would this not suggest pump and flow is OK. Pump has been replaced (although last engineer did comment it seemed quiet, but...

Anyone know where you can but a foaming root killer to top roots growing in drains. Just spent the weekend clearing roots out and don't want them to come back. Seems you can but Root Killer in the USA but nothing in UK? If no to foaming root killer any other way to kill em...

Well hi and low thermostats now replaced and no better ! Pilot light goes out once boiler gets too hot. I can get hot water because water gets hot enough before boiler overheats. But with the central heating it takes longer to get house upto temperature (21C) and boiler gets too hot knocking...

Thanks for the info, will have these changed. Soon will have whole new system ! With regard to sludge etc blocking up the heat exchangers how can I check this is not a problem and how do you prevent it becoming a problem? Perhaps a basic question but I am learning fast and thanks for the...

Once again thanks for the reply Apparently there are 4 thermostats! What do I need to do to check for sludge etc and how do I clean? Don't know the history of the boiler as just moved in to this house. For sure pilot light going out everytime now once either hot water or central heating on...

Pump is on max speed, turned it down and no difference pilot light still goes out but this time radiators did not get so hot

Thanks for the reply What's the boiler? Model and output please? Myson Apollo, output don't know, currently at work will advise when get home Could be blocked pilot, faulty boiler/overheat stat, gas rate, connections .... Do you have TRV's on all your rads? No Do all the rads get to the...

I have a Myson boiler on which the pilot light goes out once central heating has been running for 1 hour +. So far I have had new pump fitted, new 3 way valve fitted, new thermocouple fitted, new over run controller fitted and new room thermostat fitted. However pilot light continues to go out...
