Thanks for your response. This sounds promising but a few follow ups if you don’t mind. 1) With only a 20mm build-up, what floor covering did they have? They can’t have had much room for any insulation, if any at all?! 2) My heat calculation was done by a website. I put in floor construction...

Thanks Notch, very helpful. The £7.5k quote I had was for digging floor out, type 1, sand, DPM, 100mm celotex, concrete and screed with UFH included. Doing the dig myself saves me about £5k - builder and plumber will do the making good for £2.5k - that sounds okay to me. I have zero building...

She pushed through the knocking down of the walls / putting in the steels. I’m reserving time to make sure it’s heated properly and finished to a high standard. She’s more interested in granite v. Silstone worktops...

My wife.

Hah. I have time on my side - limited only by how long I can put up with 44square meters of my house being unheated. Not long is the answer in this weather...

I’m in Bristol if you’re that easily persuaded!

I’ve got a few mates who’ll work for a few beers in the evening, so that’s good. I just need to be prepared to barrow 6 tons of concrete from their houses if the need were to ever arise...

This is also true. Think I may rent a breaker for a week for £50, order a skip and get on with it.

Out of interest - how long to break it up and remove the floor? That’s where the majority of the cost is, so was thinking I could do it myself.

Far from pristine! Just had the wall separating the kitchen and dining room; bit of a building site. After taking up current flooring, the original concrete slab is covered in asbestos tiles. Concrete is in good nick and dry. Have no reason to dig it up other than for UFH. If this UFH exercise...

how come it’s not a good candidate for payback calculations? Radiators likely to cost a lot too - and channelling for pipework etc. will be messy and annoying!

I’ll let you know when I get one back! I appreciate that there is an optimum way of doing this, but I’m also interested is the payback. If I’m losing 10% through the floor on a £800 per year gas bill, then tearing up the concrete and relaying with celotex at a cost of £7k is going to take 100...

Any thoughts on the Kingspan Optim-R solution? Looks high performing but no idea if it can be used.

I’ve had a quote for doing precisely this, including the UFH system at £7.5k. My concern here is that it doesn’t react that quickly, but is the most effective way of doing it. The sandwiched system does respond quicker but for that you lose heat through the floor.

That’s my fear. Nothing else will do it?
