Ralph Posted June 19, 2019 Share Posted June 19, 2019 This is the price we got for supply and installation of an ASHP, underfloor on ground floor and radiators on 1st North of £18k seems a bit expensive to me.

Nick1c Posted June 19, 2019 Share Posted June 19, 2019 Others will be better informed but a couple of things occur to me. It sounds like an MCS install to get the RHI, have you worked out how long it will take to get the 'MCS premium' back? You may be better off using a cheaper, non-MCS accredited installer & forgoing the RHI, which is pretty low now anyway IIRC. Why not have UFH upstairs too? No wall space taken up so more flexible. My current quote for UFH, in slab on the gf & tor board on the ff (180m2 total) is circa £4500. Link to comment Share on other sites More sharing options...
A_L Posted June 19, 2019 Share Posted June 19, 2019 12kW seems a lot for a newbuild. What floor area/insulation/air leakage? Nibe is at the expensive end of things so price for heat pump seems O.K. What sort of floor for the UFH and who is laying it? You will be paying for an 'RHI premium'. Most people on here get heat pump etc from ebay etc for a fraction of NIBE prices and forego the small RHI income on a well insulated house. 1 Link to comment Share on other sites More sharing options...
jonM Posted June 19, 2019 Share Posted June 19, 2019 In terms of price, Nibe is the Rolls Royce of heat pumps. I had a quote for supply and installation of a Nibe 4kw heat pump and cylinder of 11K. I am using a Mitsubishi heat pump and cylinder which I paid £3.7K for. Your Stelrad rads are about £300 each online so again a significant markup. We are not bothering with RHI as the house is passivhaus and the cost of the monitoring equipment required would outweigh income. Link to comment Share on other sites More sharing options...

Floor area is 200sqm , don't have the u values quite finalised but the quote was based on using a scotframe kit which was quoting u values of 0.16 for the walls. 11 hours ago, jonM said: In terms of price, Nibe is the Rolls Royce of heat pumps.

I think we went for this particular installer more from the point of view of them having a good reputation rather than RHI although you both make a great point about that. We've heard quite a few horror stories in our area of ASHP being badly specified or fitted that we did not want to take a chance, Re quotes from other suppliers obviously needed .

The feedback we've had on the UFH upstairs has either been that it's not necessary and a few radiators will do (we've been quoted too many radiators) or that there have been issues with things like floor boards and joists creaking and pinging when they warm up cool down.

Floor boards and joists don’t creak and ping - that’s rubbish coming from installers (who don’t like doing it. Glue the deck to the joists and it is going nowhere ..! And the low temperatures needed of the water mean there is little expansion. Link to comment Share on other sites More sharing options...

Assuming buildings regs levels of insulation and reasonable levels of air leakage and no MVHR 8kW should be sufficient. Link to comment Share on other sites More sharing options...

That makes sense, what level are the extra costs for UFH upstairs rather than rads in terms of flooring materials? Do you still need some sort of screed?

Do you still need some sort of screed? You can use a screed but tends to be with concrete upper floors. You can use biscuit mix or other infill but you need to make sure your engineer will have included the weight of the screed in any timber or concrete floor solution.
