Well there’s no going back now. I used gap filling cement anywhere I mixed brands otherwise I just used normal cement. Now I just need to put some foam around where I cut the insulation. Tape the joints. Cover it in dpm. Then mesh , them I get to play with some UFH pipes ?

TO find a custom maker, try EBay. You will need to do a bit of due-dil but there are good companies on there. However, personally I would hinge the door off the wall as suggested. I would also make it at most 1.842m high to avoid having to flap around with chopped off corners .. I think 6 ft high is plenty ... works fine in my alcove shower with a gap across the top. Personally though I would leave the 2nd panel off altogether and have a single fixed panel (800mm wide maybe) and an overhead brace, walking in around the side, or a single door and a gap. But I hate moving parts in shower enclosures as they get horribly skanky and sometimes wear out or break. Ferdinand

Thanks Nick, very helpful. Yes, It's an open, vented system. Mains pressure isn't exactly explosive here but higher than my hot water pressure. I'll have a word with my plumbing supplier when I buy the tap.

Interesting

No doubt teaching you to suck eggs but when you foam UNDER the long run pipes they can lift and bend in the middle shifting the traps etc. Worth weighting down in position with a couple of bricks/blocks.

I can advise that taking the water metering head off is not advisable! Getting the gears all back in place after they've all come off their spindles as you lift the cover is very far from easy.............. The perils of being intrinsically curious by nature; I just had to take the thing apart to see how it worked.

I got it first read though, but Morgan don't make lorries, just wooden cars

@Construction Channel Ed, totally agree with losing the rodding point as that shower trap is what I referred to as 'open', so iechyd da! What I would do though is swap it to the other run so you can rod as far as the bath tee. I think you suggested that above ? Access from the basin end really isn't necessary imo, but please do use 40mm pipe from the 50mm bath tee all the way to the bend that faces the basin trap. Into that bend you fit a 40x30mm internal reducer and then the only 32mm waste pipe is that short horizontal bit to the trap. Fit and forget. The fitting on the shower traps are always a pita. It offsets down so you don't have the knuckle of the fitting touching the underside of the floor covering which levels with the flange. You need a 40x50mm compression reducer to go on that trap and do away with the bit you show. That should work just fine, or you may need to use 1x 40mm 45 and then an M&F ( street ) 45 to get the offset back. Rodding through two 45's is no problem at all. This straight off the trap, and then this to correct back to straight and turn the lot to give whatever offset you need. Or if you want to get to solvent quicker before you bump up to 50mm, put the male side of this into the compression 45 and then a piece of 40mm waste, then a 40x50 offset reducer into a 50mm coupler and away to the stack. Hard to say from the pics if you'll need the offset or not tbh.

Can we stick to the facts only please

I still think, even with an acceptable degradation ( whether it be purely by cycle, or both cycle and life combined ), the degradation / lifecycle is still very economical vs the available alternatives. No multiple components failure like you suffer with gas boilers, or maintenance, other than a failure of the immersion to deal with so 'cheap motoring' AFAIC. Add to that no flue / ducting to outside etc etc, plus with the 3rd gen theres no integral pumps / additional wet plate heat exchangers / flow switches / TMV's / control wiring etc etc there's very little to go wrong. These are very impressive bits of kit

Just guessing here, but generally when you heat cycle any compound there will be some change, perhaps not an intrinsic property of the compound, but maybe a very small reaction that happens between the compound and the materials it is in contact with, for every heating/cooling cycle.

I have a single sample point for sodium acetate in a hand warming pack. I came across this during our pre-move major clearout around Christmas time. I can pretty much pinpoint when it was last used, which was November 2004. I had charged it after use and put it in a drawer, where it sat at room temperature, in it's liquid phase, for over 12 years. When I initiated the phase change it worked normally, turning into a solid and releasing the same amount of heat as it always used to, as far as I can tell. The interesting thing for me was that it had stayed in it's higher energy state for that period of time. Looking at the basic chemistry, but not knowing the exact composition that Sunamp use, I would doubt if there are any purely age related degradation effects, as long as the seals are good on the heat battery containers. Be interesting to find out more, but I'm leaning towards the view that the thing will outlive me.

I would pull the door back to the wall and hinge from there, and then have a single panel to the right. 8mm tempered glass should be £450-500 at most

When I was digging around for data shortly after the fire, I found many, many examples where materials, including those used on Grenfell, had been approved with no testing at all, just a desktop study. The problem with the latter is that some of the extrapolated data is so far removed from an initial test result on a different material as to be useless, yet this doesn't seem to be picked up by people like BBA at all. As long as they get a fee and are given a compliance pack that looks OK on the outside, they issue a certificate, it seems.

New article in The Times today says that investigators have not been able to find any record of independent tests on the combination used on Grenfell tower, either in the UK or abroad. This combo was used on 299 similar high- rise buildings. "Somehow or other, those materials have got onto 300 buildings without any tests being done or test results being produced." Related...
