Onoff

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...

Now be honest, it was the shape that attracted you?

I rate these too. I've a red pair as well from Screweys that I think are a "make" , no real difference.

People might be a bit reticent about telling you what they have and where they are on an open forum!

I had a chat with Kevin from CT1. He covers the Midlands but is happy to talk / help on any CT1 related question. Some interesting comments: "Clear" products like CT1 are generally considered "weaker" than their coloured siblings. They don't add pigments. Apparently you can tell the difference if you pick up a coloured and clear tube of CT1. Early 2019 they are reintroducing their WT1 tanking membrane. Before it had to be trowelled on but they have revamped it to go on with a roller. They do a new Anthracite CT1. If you order a pallet or more (2500 tubes?) they'll do it in a RAL colour of your choice As to my enquiry ref using CT1 Power Grab n Bond to put tiles onto marine ply: If I was going straight onto the ply he said he'd have no issue. The fact I'm tanking he's worried about a reaction between the Aquaseal membrane and Power Grab n Bond. Anyone know what Aquaseal is, polymer, latex etc? He's suggested I stick a tile sample to a piece of tanked ply that has been then primed with tiling primer then another tanked but no primer.
