    Thanks for your responses folks, very heartening. I'll stop fretting on this one. As said above my building inspector has requested such a certificate and I have requested of him why it's needed in my case, but no response - hence my query on here.

    As part of completion paperwork Building Standards have requested a heat pump installation certificate for my ASHP. Has anyone in Scotland experience of this or have any idea of the regulation where this is cited? I've installed the heat pump myself and I'm not applying for any incentives. Thanks

    I hope you're pleased with it! Did you use the controller to set the temperature? I remember reading you had problems. I've not tried mine yet.

    I have a Kingspan Aeromax Plus 6kW @Joe90. Looking at this diagram in the blurb it seems the pump should go on the return for the Kingspan, thanks @PeterW

    Thanks @PeterW, you're a ?
  6. JIH
    Thanks @Joe90, I think I shall therefore try and position my pump as close to the ASHP as possible.

    Thanks @PeterW, just a simple connection across as above? Does this need a valve?
  8. JIH
    Thanks @PeterW, I don't have room for a buffer tank in the space unfortunately and have already bought the willis heaters.

    Yes, thanks @joe90 I have a pump attached to the manifold (as shown in the diagram in the box on right), but I thought I would need another pump in addition to the UFH circulating pump.
  10. JIH
    Can anybody help me here? Does this look ok? Correct to have circulating pump on the flow side? Should it be as far from the UFH manifold as possible?

    Jilly - I'm happy that my ASHP will be adequate to heat my house, which has a high level of insulation and air tightness. You may be correct that additional heat could be required in extreme conditions - but this could be achieved with a fan heater and does not need to be part of the system design in my case.

    After much heart ache, time and tears I'm looking for some advice from you guys regarding my heating system, which is completely separate from DHW. I plan to directly heat my slab with ASHP using Willis heaters as back up. Hydraulically does this look ok? Input much appreciated.

    Vacmaster is my recommendation which I got after returning the smaller Titan vacuum which I thought was a load of shite! Much cheaper

    The evidence is clear @Onoff

    Should ready more pipe clips
  16. JIH
    All sorted now @Onoff, thanks to Nick's cunning plan. Thanks again for the offer. J

    Ok, thanks Peter. I'm learning. . . . slowly Is there a reference somewhere that would enable me to work out the offset achieved when using a pair of bends? What I really need is dimensional drawings of these waste fittings I suppose.
  18. JIH
    Oh cunning plan! I like it. I just need to buy pipe clips instead Thanks very much

    Umm I thought what I had was effectively a manifold system with 2 WCs. Below is exert from Marley's design and installation manual where they use 90 degree branches. As long as I have a good angle to give fall into the horizontal pipe do you not think this would be ok? I might have to use a shallow bend vertically on each line just to give the fall.

    No worries. Enjoy

    Nothing happens quick around here! That's a very kind offer, thank you. If you happen to have a couple of straight connectors (366.887.16.1) surplus to requirements I would be most interested
  22. JIH
    @PeterW I'm not sure I understand your concern here. If, as suggested above, I use the 90/90 mm straight connector (366.887.16.1) instead of the supplied 90 degree bend, I would then use a 90/110 mm reducer to get me to 110 mm and connect to the stack. So my thinking was that instead of using the 90/90 mm straight connector + 90/110 mm reducer I would just use the 90/110 mm straight connector (367.887.16.1). Or am I missing something?
  23. JIH
    Thank you so much Peter! Yes that's great! I was struggling for height with your original idea. They're not cheap are they? And I see they also do this straight adaptor from 90mm to 110mm (367.887.16.1) which will save a joint. Appreciate your help.

    Hi Peter Please excuse me for being obtuse - but I'm not following you completely. This is how I had envisaged the connections working, with the bathroom WC joining with a 90 degree branch to the pipe for the en-suite WC, then joining the stack with another 90 degree branch. (Please excuse my crude drawing!) But with the fittings supplied with the Duofix this layout is not achievable. So are you suggesting that I use the supplied 90 degree bend, shorten and add another 90 degree bend and then get to the stack as per the above layout albeit 210 mm lower? Would it be acceptable to introduce more 90 degree bends? I take it you are referring to the expense of Geberit pipe fittings? Do you think that instead I could use this straight out of frame?
  25. JIH
    I had hoped to use Duofix cistern and frame for my wall hung toilets in the upstairs bathroom and en-suite. As you can see from my plans these toilets back onto the coombe/void/storage space, where the stack is. But looking at the Duofix system they appear to be designed only for vertical outlet or sub horizontal, perpendicular outlet. Has anyone experience of this situation? Is there a reasonable get around? Or another system other than Duofix that I could use? I'm reluctant to turn the WCs around by 90 degrees as they would then be at right angles to the ceiling slope. Thanks.
