and check out the suppliers on the "other" side of the Irish Sea too...

regardless of the price of panels I'd suggest a trailer or something is a near-must for a build...

And it keeps on keeping on. Down to my last stack of plasterboard. Been doing some diggering of soil and rubble outside so the topsoil mound is smaller than it was and we've an inkling of the shape of drive and garden. But more interesting stuff. As I'd mentioned elsewhere I'd ordered the thermal store- from the lovely people at World Heat- after it became apparent that Harlequin have moved away from larger and multi-coil variants of the Heatstream. Bit of a b*gger as I'd already pre-plumbed some stuff with it in mind. Hey-ho. 270l active, with expansion space above. Direct tappings from the boiler stove, an HP coil (15mx 35mm corrugated), a 15mx 25mm DHW coil, and two immersions. All in stainless. So tank is in place and sufficient of the plumbing done that I was able to fill it last night; from a stone cold start today it had got to over 51c and tripped out the 'stat (that I'd forgotten to turn up...) off diverted PV, and today wasn't terribly sunny. 7kWh diverted, according to the iBoost. I'm very happy with that.

dunno. No reason why tho...

what's wrong with composite?

I know a lot of folks here recommend Telford but I'll throw a nod in for World Heat- you're not forced to go through a merchant, fully bespoke as necessary and (essential for me) happy to deliver to NI. Their coils seemed a bit bigger to me than some others I was looking at too.

no service void on the inside will be a pain.

on his own or does he bring someone/ use you as labourer?

Better to go 8.5kW and modulate down even on the Gold Coast... The various different calculators all come out between 2.5 and 4.5kW for our place IIRC but I'll be going somewhere between 8 and 10kW to ensure plenty of headroom for DHW.

80mm plus service void? That's LOTS of very long screws...

Nope, just the rough-sawn tanalised stuff from the local yard. While I *did* follow GSE's spec, it worth pointing out that a. the thickness needs to match your tiling battens and b. the wider the plank the easier it is to aim for...

4x1 treated.

why so focussed on warranties?

showers aren't inductive. Bog standard 2hp induction motor may have a peak starting current of anywhere between 25A and 40A so soft-start is pretty relevant. Doesn't change the fact that the unit doesn't modulate tho...

have you tried BPC for a design quote?

I'd caution that soft start is very different to inverter...

Yes, they'll quote by height with whatever base starters or lintels, pots etc. Check the price between Isokern and Swift, too.

Scheidel quote including the rockwool insulation, the actual blocks and pipes, adhesive etc. It's really plugandplay (especially if you're rendering the blocks directly, we built a skin of standard blocks around the system blocks) even if the blocks are *heavy*...

is the upper strip wrapped around the floor cassette as a TonyTray perhaps?

I went with ceramic https://www.schiedel.com/uk/products/ceramic-system-chimneys/swift-air/ which also neatly looks after supply air too. A complete system inc the outer blocks etc was around the money the OP mentioned.

V-tac's "grill fitting" strips are superb if you want something more "linear". Light and plasticy, but great light output, run cool, and cheap! https://v-tac.eu/led-products-results-page/led-fixtures-1/?custom_f_145[0]=3134302d313630206c6d2f57&custom_f_145[1]=3131302d313330206c6d2f57

why not just an ordinary laminate worktop?

perhaps the "little boy" (condescending much?) was uncomfortable with accepting the liability for agreeing to something that isn't in the MIs?

Polarwall will supply XPS...

Since when was a PV diverter £500?
