Discuss New member, can someone help check quality of this boiler install? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Didn't mean to do that was trying to quote. Still getting used to this new forum haha
you got harvest all excited
Slightly off topic but is an 18kw enough for 12 rads and hot water? Smaller ones in bedroom, 3 of them tower rails.
I would say your close too close needs working out
Heat loss each room and add 3-5kw for a copper cylinder or 15-20kw for an unvented one
Just added up all the current rads in the house using a KW calculator, came out as just over 10kw currently. Upstairs have older 600 x 400 single panels that seem to put out about 0.35 kw each. Should have a bit of headroom with 18KW.I would say your close too close needs working out

If in time the coil was to pinhole in the cylinder the primary water would contaminate the secondary water.
Cistern must be fully supported on close boarding. Which the F & E seems to be. Looks like chipboard or OSB where I would prefer to see 18mm hardwood ply, but perhaps it's a matter of preference. The boarding is on three supports, so it won't be going anywhere, after all.Also it wouldn't meet the regs regarding support of the cisterns from memory.
Moving everything back down to the airing cupboard below, repiping etc. 2 guys.You will find that most engineers will treat it as a complete new install. Even though the boiler is already there. Seems a little high but depends on what you are getting for that?
Yes looks like he’s fit a 22mm feed to the boiler from the 15mm in airing cupboard.View attachment 31958
Looking at the pipework layout an then the photo of your airing cupboard I do think that’s the gas pipe
I’ve asked him whom installed. I’ve got a feeling he is not Gas safe. He’s already confirmed that he removed cover from broken boiler to me via text so potentially broken law already.I would get gas safe out asap least if he is not registered there will be a report
Have you asked him for his gas safe reg ?
The board needs to be a minimum of 150mm larger than the footprint of the cistern, supporting timbers 350mm centres, inlet one end of tank feed the other, no insulation underneath CWSC.....some of the things I recall.Exactly what would happen with a sealed system. I agree that it is better to have the cold water storage cistern at a higher pressure (height) than the F & E, but I asked this question on this forum and consensus was that there is no regulation on this (and, in this case, it would not really be practical to raise the existing cold water storage cistern to a higher level just in case, one day, the coil fails). I would have done the same as the installer has done.

I am, though, suspicious that the combined cold feed and vent pipe coming out of it may not slope down away from the cistern as it should do. I would also expect the cistern to be lidded and well lagged when the work is completed.
I really don't think the installer installed the cold water storage cistern (the large one) - just the F & E - else I'd be moaning about lots of things. But this is good information for the OP as it shows best practice for the new Combined Cylinder Feed and Cold Water Storage Cistern that will be needed.The board needs to be a minimum of 150mm larger than the footprint of the cistern, supporting timbers 350mm centres, inlet one end of tank feed the other, no insulation underneath CWSC...some of the things I recall.

As far as the F & E is concerned:
150mm figure not in Water Regulations and I've only seen it in the Maskrey plumbing textbook so it may only be advisory. I don't know that it isn't in BS EN 806, but EN 806 is for water for human consumption - clearly the water in an F and E is not for consumption. Quite honestly, I'm not entirely certain what the point of this 150mm is, except that it does give a useful space on which to fix pipe runs.
350mm centres for supports is for steel cisterns which can be placed on supporting timbers without close boarding. I can't see the measurements, but looks like the F & E is supported by three bits of timber, so probably okay. Common sense dictates that the platform for a cistern should be adequately supported, and a 50 gallon cistern obviously needs more support than a 4 gallon F & E.
Inlet one end, outlet the other is to promote flow through the cistern to avoid stagnation of potable water - the water in an F & E does not flow through in normal use, and is not used for drinking. In any case, looks like the float valve (ballcock) on the F & E is yet to be fitted.
The bigger footprint is apparently when a thermostat failed(pre having the reset) and was forcing boiling water out of the vent pipe, the CWSC was not fully supported and distorted and the scalding water came through the ceiling and a baby was in a cot directly below and tragically died of injuries sustained. It looks like the feed in CWSC is the same side as the draw off(stagnation)View attachment 31958
