Onoff

Look again. 135deg included angle not 90. (I've got 90's)

Next size jubilee clips down - get from the local motor factors. Smear of silicon grease (not Vaseline...)

How about you change yours to Teutonic and people would get us mixed up?

Welcome. Mind if I nick "Tectonic" as my new username?

I wish you'd have been on here a while back! Might have given me the impetus to get my 3x12 panels installed & going before they got broken!

You could use say parrafin wax as the pcm but surround it with a water "jacket". Bit like this fast breeder reactor Parrafin wax goes in the "rods". Thinking this arrangment would maybe prevent localised overheating of the pcm...

Aren't external "yard" furnaces popular in the States? Can't see the issue of a well insulated, bfo buried tank of oil/wax and well insulated pipes into the house like on an ASHP.

And lower heat losses with a lower "conventional" water volume I presume?

Could you then... Use the PV to pre heat a conventional store then use that store to feed a water heated Sunamp?

@Nickfromwales, me again! Did you have some cunning ruse for trimming this corner without "sharp" edges. Getting close to it happening! Was it on these lines? Cheers.

A bit like when I had a MAJOR contractor subbing for EDF come and replace an incoming head and they left without fitting seals (and there was provision for two)!

In my defence I have been under a lot of stress during that time...

Off into uncharted, make it up as I go along territory with this bath end panel! Decided now to have just one bfo removable panel at the end which I'll pre tile before screwing on with some neat, diamond drilled screw holes that'll be siliconed over. Or something like that...still evolving. Pita that I've run out of 12mm marine ply aside from two bits when I was going to clad each half of the bath end. Biscuit jointed them together with Gorilla glue:

Chuck a few Toffee Crisps & pizzas in & who'd argue?

Some things...

Window wall inc reveal and one pocket done, awaiting grout. WC wall and 2 pockets done and awaiting grout. Tempted to grout these bits but I like to finish one thing before I start something else...

Buy a soil pipe wall bracket and clamp it on. Use that as a guide for your handsaw. Or keep an offcut of pipe with a split and use that to draw around or as a guide for your multi tool. Like I did on this pipe to cover the water meter: Or use a mitre block (& Bacho saw):

I've always thought organic compounds are a possibility like palm oil, cocoa butter or high sugar "jam". Think how hot a McDonald's Apple pie stays! Place outside rather than inside the house!

@jack...haven't you got a recovery thingy on your shower?

Your wish etc:

£24 worth of "let's try this stuff out": Seemingly the Aquaseal primer is a "styrene acrylic based polymer". Had to travel to get this stuff in the picture whilst waiting for CT1 to tell me a local stockist. Turns out the BM in the next village carries it! This stuff is apparently based on "ordinary" CT1 which is a hybrid polymer product so I'm hopeful it'll all be compatible. EDIT: Nards! It's only £9.99 at the BM near me.

Dunno, thinking about Felicity Kendall now...

Yep. The Sunamps impart their heat to the water more efficiently too I believe. It's a space thing also. The Sunamps are a fair bit smaller than a "water tank" type heat store. That being said I've often wondered as in my case (space rich, cash light ), whether I could just have a MASSIVE heat store and just treat the heat loss as space heating?

I wouldn't mind a "floating box" but that looks like it's sat on "goal posts". The ideal would have been to have supported the box using hidden steels perpendicular to and instead of those goalposts. The stairs position might have compromised that idea. Failing that suspending the box from a hidden, up and over frame would have worked.

I think my bathroom is coming in around the £18.50m/2...
