One odd install I saw was an OV oil boiler in an airing cupboard. Custard had decided that the flue which ran up from the boiler past all the shelves of linen through the ceiling was too hot even for their liking. So they got an old sheet and tore it into strips and wrapped it round the...

well if I went to that installation I would also take a photo and then explain why I am not going to work on it, unless they want me to remove it and fit a new boiler. What about side clearances? The PCBs on those go fairly regularly, and to do that you have to get a screwdriver into the right...

So, Potterton now make tumble driers as well as boilers! :lol: I am still trying to work out how many violations there are on that installation. Reminds me of the last time I had a GSR inspector visit on a service I was doing. I did the boiler then went outside to inspect the flue. A...

I was only doing breakdowns on other peoples installs. One I remember going to was on their second lounge ceiling after the last effort at fixing the fault wasn't done properly. I agree, if the pump is wired correctly and works correctly then the boiler gets its power via the pump. This assumes...

Call WarmFront, offer grovelling apologies and when the guy comes back make sure you demand a Baxi off them. They do Baxis as well as Ideals, but only about 1 in 100 are Baxis. I reckon if you insist on a Baxi you would get one. Just make sure the installer knows that water runs downhill - not...

I've heard this theory from scale reducer manufacturers as well. "The electromagnetic field disturbs the calcium molecules so that although the calcium still exists, it does not stick to metal". I have worked in electronics R&D labs for more years than I care to put on my CV, and done a lot of...

Yes I must admit I had wondered about that. The oxide in the condense trap must come from the water content of the gas. You don't get it from stainless steel heat exchangers do you.

I had a long talk with a water softener manufacturer recently. How do they work? The hard water passes through a tank full of resin beads which attract the calcium in the water and it sticks to the beads. Once in a while according to your water hardness the softener back-flushes the resin...
