    I know this is an old topic but i'm guessing that unless the windows are fitted flush with the outer frame (or overhung) then water ingress protection of the outer window reveal is needed, hence the DPC in @oranjeboom 's original drawing. This maybe more of an issue with a timber clad option due the reduced depth compared with brick or stone. What did you go with @jack?

    @PeterW Great drawing. WHat's the tank adjacent to the UFH manifold. At first I though it was a buffer for UFH and maybe a take of for rads but it has a coil and the UFH is a direct feed to the UFH?

    Any particular spec for the Rockwool? I've got 304mm posi joist so that woullkd be a lot of Rockwool, and it may be beneficial to get some heat transfer to the 1st floor?

    @jack great reply thanks.

    Ca I ask does anyone have detailing of drainage for a parapet roof. It was mentioned above that a drainage 'gutter' be formed in the insulationto fal to the outlet position? Is this necessary. Would not a depression at the outlet be sufficient? My architechts drawings show neither. I am going with posi-joist, firings, 18mm OSB, VCL, 220mm insulation (120mm on green roof), mechanical fixings, EDPM. Firestone mention topping the insulation with 12.7mm ISOGARD HD which is fibreglass covered PIR - is this necessary, why not 11mm OSB?

    Thanks @Nickfromwales I'll ask them. I'm struggling a bit to physically incorporate separate zone valves for new and old rads due to existing pipe runs Do you think they are necessary? Would rad TMV's be ok instead? If you have time a schematic would help me confirm what I need. Thanks.

    @Nickfromwales, just thinking about ordering (cylinders2go?). Presume that the buffer doesn't need a separate expansion tank or prv as it uses the one on the system boiler? Still wondering if a TS would be a simpler and cheaper install?

    Thanks @Nickfromwales, invaluable advice as always. @CC45 thanks for the post, yes it was join the dots but point taken. @Nickfromwalesany view on boiler make, leaning to what I know so Grant, and if you have better schematic then I'd welcome it.
  9. Silage
    High praise indeed @Nickfromwales. now would you use the same tappings for rads and ufh as below or seperate? What other components are missing?
  10. Silage
    @Nickfromwales, like this?
  11. Silage
    As I'm now moving the boiler outdoor then was looking at an outdoor version of what I have, Grant 15/26 Vortex Pro outdoor system boiler unless you recommend otherwise. Those were heat figures,, actually I got more like 2.9kw (primarily due to the glass link with the old house so could be a bit more) + 12kw and I guess add 3kw for DHW? Controls wise, room stat per zone and one for ufh I guess or would you go whole hog with Evohome and rad valuable etc, probably ££££!

    @Nickfromwales thanks. I've only got PowerPoint so difficult to sketch in it. Yes I see what you're seeing but I think it's just my drawing. The return from the buffer should go to the other side of the boiler pump as should the return from the uvc. A sketch would be great if you have time, advice on controls even better. The existing is drafty in comparison, will work on it in the future but esimated that it takes 12kw vs 2.5 kw for the new!
  13. Silage
    @Nickfromwales is my schematic anything close?
  14. Silage
    @Nickfromwales, are you saying that the rads would be better off the bufffer then? Is that why you suggetsed 120L? Otherwise Tevor suggested a 90L for just UFH (70 m2). Trevor also pointed me to merchants such as Cylinders by Choice rather than direct sales. @PeterW does you buffer supply just UFH?
  15. Silage
    @Nickfromwales, rads direct off system boiler? Would you put the UFH manifold at the buffer tank, the circuit is 5m away.
  16. Silage
    Yes, that's their schematic. So 120l buffer, 250l uvc (maybe 300l as 2 soon to be teenage girls in house?) and rads driven of the boiler direct? Does anyone have a schematic of that with controls? New outdoor boiler probable need to look at make and size (happy with my Grant vortex pro but indoor).
  17. Silage
    Thanks @Nickfromwales and @PeterW. I had thought so but Greensquare view is it's just extra cost. Would the rads be direct feed from the system (oil) boiler then. So the UVC is just for DHW? For 4/5 people , 1 bath , 3 showers say 250l? The ufh is 71m2 so buffer size x? Existing rads x 9 and new ( in MBC build 1st floor) x 2 or 3), estimate about 13kw heating load in all mostly in the old house.

    @Nickfromwales
  19. Silage
    @Nickfromwales Telford seem a good bet for supplying my UVC. As per other post on UFH with rads but I will now site the tank in the cellar and have an external boiler (fluing from the cellar is a pig and looks expensive). So presume new system boiler and UVC or TS. Can't invest in solar now, or air-source hp as no funds left. See system below I got quoted from Greensquare. Should I not have a buffer if going uvc?
  20. Silage
    Looking at repositioning the boiler outdoors. Any advice on good makes. Current indoor is a Grant Vortex Pro - not cheap though. No solar planned now as run out of funds so just UFH and rads plus DHW.
  21. Silage
    Yes both and good point @Nickfromwales. A builder told me they had to be run in an insulated tray hence the question.
  22. Silage
    Very helpful as ever @JSHarris, and yes I do need some T&E to the island of course so i'll do the same, thanks. Is there any need to run Pex water pipes in a tray or can it be clipped to the mesh like the conduit, not sure if @Nickfromwales has come across this?
  23. Silage
    Just planning out service runs for DHW/CW to the kitchen island. What is required to run under or through an MBC slab that has mesh/ufh? I also need to to get the UFC into the plant room that is outside iof the the foundation footprint.
  24. Silage
    That's great news @divorcingjack, very pleased for you. it's stressful this lark and i'm 8 weeks off build! Not sure who you used, MBC? C35 concrete?
  25. Silage
    @Calvinmiddle we are at the stage of choosing cladding profile. Can you post more of your (board on board?) design or PM me? We have considered rain screen and half lap. We are thinking that we want to create depth/tone or at least breakup the possibility of a monolithic look as it silvers as we have quite a lot of cladding (in particular on the north wall with few windows), we will have vertical and horizontal to break up but even so. Thanks.
