    Mmh, I'm inclinded to agree with @Dave Jones - I am unsure what Global vs UK really has to do with it - UK grant scheme is evidently an implementation piece for a wider global market, underpinned by carbon tagrets, incentives and fines. We need something done about carbon, no question there, so it is not all bad - but there are racketeer companies making hay while the sun shines (quite literally ). Maybe slightly tangential, but there is precious little vocal advocation for the consume-less solution, just consume-better which looks like consume-more-better.

    I've read about half of John cantor - linked above. It's a solid, informative explination of HP, but I still don't feel ept. Mind you, he says at the start that it comes together near the end. Even if it does not fully come into focus, it's a great basis to start to understand what you are buying. If it does come together for me, I might design my own system - after all, there are a lot of trade off decisions between investment and cop that only I can judge. Highly recommended read (with the tv off and kids away)

    Is this the wrong link, or am I missing the joke?

    Yes, I really hope to not be the only one in the house who can "turn on" the heat! I know, maybe "turning it on" is old hat, but you know what I mean The discussion, even if not conclusive, is always reassuring. Oops!

    On grants, being the cynical sort, I'm assuming that nobody (other than the homeowner) really gives a monkeys whether the technology actually works, reduce costs or reduces footprints. I expect the main concern is that when 2030 comes, we can multiply the number of installs by some other number to declare some big victory and reduce any fines due for breaching our carbon-reduction commitments. Maybe I sound too cynical, but in my last home (in R of Ireland) I had to fight tooth n nail not to lose my grant because I refused to let the retrofit cwi bead installer drill a drafty 4 inch ventillation hole in all rooms. Referring back to my op, and the discussion above, I'll hold tight again and won't buy blind. Thanks all for help.

    Ah, that is smoke and mirrors, and somewhat high handed. As always, thanks all for your comments

    Who do you think is behind the withholding, the supplier or installer?

    Exactly,and I'm nervous that if I insist on info, they'll walk away. Is one approach better than the other? I think @SteamyTea prefers the buffer approach. As I have a main contractor and a job, I'm aiming to be informed of the detail, and influence it if I have concerns, rather than DIY. As a sanity check - this is reasonable and sensible, right?

    A pointer, please. I'm building new and I have opted for ASHP (I've seen nothing especially wonderful about ASHP, but it seems to deliver at a comparible cost to oil, and easier to get BC/SAP on board, but this is not the point). I'm in N Ireland and have 3 prices from installers that use their suppliers design service (Grant, Warmflow and another). None of the 3 can provide any detailed information on what their proposed system is, basically " in case the design is copied". I want to know a lot before i decide, from pipe size to zones, to controls and equipment, coz i get one shot at this, its expensive, and must work without me having to get a degree in Turning-On-The-Heat!!. Until this moment, I assumed the supplier was the cautious one, but as I write I realise that does not stack up because having designs with their equipment out there is good. Anyhow, has anyone else had this issue? Do I just hold a tight reign, or is there a better way to choose?

    @JohnMo NI or England - Yes in NI

    Thanks @SteamyTea This is 2 * masonry leaves, right? I dont suppose you know of a product?
  13. Jimbo37
    Hi Can anyione advise on the need, or not, of a membrane on the outer face of the inner leaf in a bead filled new cavity? Apparently it is to protect the inner leaf from damp, as moisture could track across the bead - new to me TIA, JAmes

    Thank you @nod

    Morning all, a bit of a steer required, please. My house is currently being built by a main contractor. Since we started, I have decided to include MVHR, and sourced it myself. The contractor has asked for 10% cut for himself. (1) is this normal practice, and (2) is 10% a reasonable percentage?
  16. Jimbo37
    Sorry to ask you to spell it out to me @ETC- is the reference 3m in 5.2 that is the relevant clause?
  17. Jimbo37
    @Radian looking at your 590mm idea. If I have 590mm drop to another level of X meters wide, and then another 590mm drop - do you know how wide X needs to be?

    My deck is 4m deep (back wall of house to edge of deck) - does that excuse me from railing?
  19. Jimbo37
    Thank you @jack and @billt I think the era of free sw for SAP does with 2012 version

    @ADLIan Is condensation the concern (presumably between the wool & board above)? @Dave Jones @Mr Punter thanks
  21. Jimbo37
    Hi Can I put mineral wool between solid joists on a flat roof - see red on the graphic. TIA

    Hi all Is Stroma FSAP still available - I cannot find a copy? Can self builders still do their own SAP calculations for BC, domestic one-off property (I think a registered assessor is required at the cert stage)? I'm tagging @jsharris, as I saw his earlier posts on the topic (although Im unsure if he is still here) TIA, James
  23. Jimbo37
    Thanks @ProDave Im unsure Im in a position to comment on the "doh", after that question @markc

    Morning folks - studying my architects drawings, and I came across this - anyone know what the aluminium sheet does (architect is ill presently, so I cannot ask her)? TIA, James
  25. Jimbo37
    Yep, obvious when you have been told - thank you.
