  1. Good to know. we're using some!
  2. 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.
  3. 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.
  4. Why Dundonald? The factory was/is in Dunmurry... Now used by Montupet, producing automotive castings
  5. are the flow and return from the boiler reversed maybe?
  6. arcing is more of an issue with DC though, isn't it?
  7. that's an odditiy, no? Wired connection from doorbell to monitor kinda negates the value surely.
  8. 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.
  9. 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
  10. https://www.ebay.co.uk/itm/DC-12V-3M-Solar-Water-Pump-Circulation-Pump-Brushless-Motor-Hot-Cooling-New/263758894915?hash=item3d69415743:g:PqsAAOSwjodaJLB2 I'm using one of these on my solartwin stylee system. can vouch for their capabilities.
  11. are those tiles all in neat unbonded rows?
  12. Insulation is good. I like insulation. It even seems to be working... Overnight temperatures are dropping radically but the small amount of heat that the diverter is putting in during the day seems to be hanging around nicely. Drops consistently from 16 and a bit to 15 and a bit overnight. And while we're airtight there's not yet any insulation in the attic and the GF is a bare uninsulated subfloor so I think we're doing OK. Was given the loan of a plasterboard lifter so that'll make things slightly less difficult in the near future. Oh and got some company for the digger, a dog-rough but useable Thwaites 4000 dumper. Putt Puttt Putt.
  13. Our guy was great. In UK parlance only an AT, but fully trained in NZ where they focus a lot more on the buildability and structural side of things apparently. Absolutely no pushing of his ideas onto us and a easy exchange of requirements and facts.
  14. me too. there's around the same gap between the back of our (black) tiles as the under-felt ventilation gap. Dunno.
  15. think it's much cooler under a panel outside?
