i have never heard of a gas regulation that states the distance from a window,are you comparing this to boiler flue regulations?

toneyt

what boiler is it?

diverter valve/microswitches most commonly,possibly the domestic heat exchanger could alos be blocked allowing water round the rads ,but more than likely the microswitch/diverter valve

sounds strange,a bronze pump is yellow/gold in colour and delivers instan t water in houses with long water runs ,so idont think its that but from what you describe it sounds like someone has wired a switch onto a normal circulating pump,not heard of this before you sure that it boosts you h/water f...

are you referring to a bronze circulating pump?

i wouldnt bother descaling get a new one and fit a scale reducer to help slow the problem down for the future

you should be able to isolate the hot water as it enters the combi,then open your hot taps to confirm isolation

Sorry to say you should get a corgi out for this as you want the supply removed from sight and i would not reccommend diy for this as the capping off needs to be tested to confirm the supply /cap is sound.

this sounds like the water microswitch is sticking and/or the new diaphragm which we are assuming was fitted is worn /sticking too,if the tap goes off the water pressure should come off the diaphragm and break the microswitch and turn off the boiler,is there a demand light on the boiler? when the ta...

commonly the domestic heat exchanger will scale up/block does the boiler fire up then off ,cycling on and off as this can indicate the boiler reaches temp internally then cuts as it senses too much heat,but the water temperature is moderate, secondly check too see if the central heating pipes heat u...

if it were that easy i would not have to retake my corgi certification every 5 years! you need to make sure that the chimney is suitable for the fire, that you have the correct volume in the builders opening(doesnt mean his builders bum!) does your new fire require ventilation as many new DFE fires ...

if you go for push fit buy yourself the correct cutter this will cut the pipe clean,square and with no internal burr, i have just been converted to plastic and in some instances its quiker and easier for a diy'er however you must not connect up to the boiler in plastic allow at least a metre of copp...

some of the gas valves for netaheats are obsolete the case seals are dwindling in numbers and the rope seal inside the combustion chamber is asbestos so be wary about these. great boiler in its day and still going strong i would personally check with the manufacturer about parts as they are only obl...

tricky,i would think that if you had the service kit fitted this would be for no hot water and he would have replaced the diaphragm,so smart money would be the diverter valve letting by which means a new valve about 100 quid for the valve alone,or i have come across the domestic heat exchanger block...
