@joe90If you can get one with a suitable diameter sensor, a capilliary stat is likely to have tighter control I'd think. or there's this: https://www.advancedwater.co.uk/prod-217-255-1621.html

Just remember that every isolator and connection is a prospective fault where high current consumers are concerned. I'd prefer to be able to see an isolator rather than waiting for the smoke coming out of the cupboard...

which leaves a big air pocket above the side tapping. They're normally fitted the other way up round these parts...

how will you bleed the air out of the Willis?

but regardless of differental across each loop surely you're still at the whim of the TMV to set the flow supply temp. I've specced two manifolds for ours- one for towel rails and rads with a Reliance mixer like @ProDave has, bit the UFH looms utilise one with a capillary sensed blender (and bypass circuit) like @JSHarris shows. It's got a low temp head on too, many capillary heads don't go down low enough for UFH purposes.

I think ours are 10kg/m2?

^ mine's the green version of that'un.

got a cracking daylight green chinesium rotary. came with receiver, target etc. Very bright, very handy.

...which is why UPVC profiles have gutters and drains.

Looks very similar to Lidl's offering, in which case it's a better, beefier pump that the clarke/sealey/SIPs at twice the price. IMHO. That pump will however be running flat out to keep up with a grit gun...

thought about it, had enough land for it, but having seen how much solid rock we have within a couple of foot of the ground, I'm glad I discounted it...

One of the green ones arrived with me last week. At 311 euros inc vat I can justify the punt...

looks like there's no flashing and the staining is from behind. I wouldn't be happy with that but I'll the more experienced hands offer something more constructive...

Lab glasswashers come with flat trays that you then add accessory baskets to. Anyone with a Miele could certainly look at G or PG range accessories if you wanted a plain tray instead of a plate rack...

Good to know. we're using some!

So I've a couple of places where soil and rainwater pipes have to cross each other. Invert depth at the treatment plant means that the soil pipes are basically on the surface at the current working level, and will have just on 300mm cover to FGL. The rainwater pipes can be pretty much any depth below this, we've almost a meter down to our open and piped ground drains. Before I go to the BCO and groundworks guy with a cunning plan for this, any easy answers or gotchas? I'm guessing that setting the pipes on pea gravel (or whatever single-size is offered) , wrapping in polythene and then haunching with dry kerb-mix ought to be the way? Or is it concrete slab time? But what about crossings? I can't see anything in the Approved Doc about them... Is the upper pipe negated when planning for the lower one? so 100mm of gravel between them? or does there need to be a barrier of some sorts? ta.

Our TF people looked after all the structural drawings and forwarded it directly to the BCO. This, as there's no ownership of the kit whilst it's still at the design stage.

Why Dundonald? The factory was/is in Dunmurry... Now used by Montupet, producing automotive castings

are the flow and return from the boiler reversed maybe?

arcing is more of an issue with DC though, isn't it?

that's an odditiy, no? Wired connection from doorbell to monitor kinda negates the value surely.

We went for Keylite's solar offering and they drop into place, you attach a couple of connectors under the top hood, and... done! One slim remote does up to 16 windows and blinds too.

I've a foot square panel that does about 10W, but have a 6v wallwart in parallel to ensure it starts in low-ish light. All through the solartwin differental controller

are those tiles all in neat unbonded rows?
