JamesP Posted August 2, 2018 Share Posted August 2, 2018 Can anyone recommend a UFH suppliers for new build as some of the quotes for supply and fit are a bit OTT. Screed on ground floor and first floor floating with diffuser plates. Thank you Link to comment Share on other sites More sharing options...
CC45 Posted August 2, 2018 Share Posted August 2, 2018 Hi, Try Wunda. Google search them. They are supply only - you will need a plumber to install them or DIY it. Good luck. 1 Link to comment Share on other sites More sharing options...
PeterW Posted August 2, 2018 Share Posted August 2, 2018 WundaTrade is what a lot of us use. Yes, you can get pipe on eBay for 5-10p/m cheaper but with everything from Wunda it all fits as a kit and it’s pretty good stuff. @Nickfromwales prefers a different pump set but have a look at the design of the blending set and see if it suits your needs. 1 Link to comment Share on other sites More sharing options...

Nickfromwales Posted August 2, 2018 Share Posted August 2, 2018 TBH Wunda are very competitive for a good product delivered. I have asked to speak to their sales manager as to why they stopped selling the capillary pump and blending sets that they used to. The blending sets I use in low energy properties are the Ivar Dualmix. Be careful to choose the wider temp range model, as one has a rather narrow temp selection. @JamesP If you send your plans to Wunda they'll do all the plans and QS list for free Link to comment Share on other sites More sharing options...

Alexphd1 Posted August 13, 2018 Share Posted August 13, 2018 I have never came across 14mm pex as in the nuheat quote. I believe the wunda is mlcp type pipe if it is, it's nice stuff to work with? Link to comment Share on other sites More sharing options...
JamesP Posted August 13, 2018 Author Share Posted August 13, 2018 @Alexphd1 I am surprised NH are using 14mm. Wunda use 16mm MLC Pert/AI/Pert Pipe. Link to comment Share on other sites More sharing options...
PeterW Posted August 13, 2018 Share Posted August 13, 2018 (edited) That NuHeat system won’t work... not the first time I’ve seen them cut cost out with only a single pump too. Ask them for the flow rate per circuit and the total flow rate of the pump .... Edited to add that Wunda have included their self regulating valve heads - they are the dogs, wins my vote any day of the week ..

Nickfromwales Posted August 14, 2018 Share Posted August 14, 2018 You need one manifold and one pump and blending set per floor minimum. Im not so sure you can't do both floors with 2 sets. Why are they mentioning 3 pumps? 3 pumps would mean 3 manifold locations, so are you doing towel rads off a 3rd ? Link to comment Share on other sites More sharing options...
JamesP Posted August 14, 2018 Author Share Posted August 14, 2018 @Nickfromwales We do have 3 levels even though the lower ground is only a metre below the entrance ground floor level. LG is 84 sqm, GF is 114 sqm. FF is 84 sqm. 2 manifolds were going to cover the LG and GF. 1 manifold for FF. What spacing do you recommend for pipes. GF is all in screed with timber floor boards and FF is diffuser with timber floor boards. Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 15, 2018 Share Posted August 15, 2018 If you go for an ASHP, then I'd go for 3 runs of pipe to a void for the areas in spreader plates, that will give you more volume so less temp required to get the equivalent w/m2, and in the screed id go for 150mm centres. You want to get the volume of water & cross-sectional area up, and the flow temp down 3 pipe plate No reason why the LG and GF cant be on the same manifold as that'll be the highest point and will vent itself without issue. Manifolds are available as big as 12 ports so no bother from that PoV but will save you cost / complexity / extra 22mm primary HP pipe runs to the 3rd manifold / no 3rd wiring centre and less physical size / impact for the overall installation. I'd be very surprised if you cant do that off one manifold tbh, ( + the second manifold for FF of course ). Ask the question with your chosen supplier 1 Link to comment Share on other sites More sharing options...

I’m still waiting for delivery a week later. I’ve now cancelled the order and will go elsewhere. Link to comment Share on other sites More sharing options...
AdamSee Posted September 24, 2018 Share Posted September 24, 2018 (edited) I used Omnie to do my renovation job. I used the torfloor system which is just chipboard flooring routed out to accept a 12mm pipe, but they do all the normal screed systems etc. The price seemed reasonable, but hard to compare as everything has to be quoted for and its priced as an lump sum. Was delivered within the week tho which was great....excepts its all be sat in my living room for 4 weeks now.
