Retrofitting under floor hearing.

Dr House · 18 Jun 2022 at 20:25

Just moved into a new place. I want to put down now floors but I’m considering fitting under floor hearing to the ground floor.

I have a screeded floor. So my plan was to mill into the floor and drop the pipes in. House was built in 2007.

Why milling? | Floor iQ

The easiest way to install floor heating in an existing screed, concrete or tiled floor is by milling slots. This avoids unnecessary floor structures or having

It’s not that expensive. Around 4.5k for the ground floor (100m2).

So good or bad idea ?

What insulation is under the floor?

I’d say yes.

It’s best to get any significant work like this and roof/wall/floor insulation done at the beginning rather than after you’ve spent a lot of time & money redecorating.

Adding as much insulation and wet UFH as possible will put you in a good place to switch to a heat pump, once the boiler looks to be on its way out.

Think it’s a great idea, everyone i know who has UFH loves it.

No cold spots, efficient. Works great with HP. No horrible rads on the walls either.

This sounds great, but without insulation underneath surely this won't be efficient?

Sounds like something that's easier to do now, rather than later. As long as it's not too loud.

The milling of the ground is a great idea and does away with the need to alter doors, skirting etc, plus the height change isn't as dramatic.

Look carefully in to what floor covering you want as a high tog carpet will stifle the heat from the UFH. I'd love it with engineered wooden floors but since we have dogs the sound of their claws tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tap tapping all day would drive me radio rental.

If you've not got a well insulated slab I wouldn't bother. I'd presume the rest is well insulated since 2007 build but you'd need to know someone more au fait with building regs at the time.

Have you decided what sort of speakers you are going to fit in the floor :rolleyes:

This. Otherwise you are going to be heating planet earth.

Dr House · 20 Jun 2022 at 22:55

This is the problem. I don’t know yet.

DXP55 · 21 Jun 2022 at 10:56

why is everyone talking about his heating - it's his hearing the Doc is on about

It's in the title and first line of the post.

Lol. Sorry for the typos.

My 2 pence, if you can afford it do it. The sub floor in your place should be insulated and the benefits from UFH are many. I fitted it in my last reno will do again in the future. It does take a little fine tuning with the heating controller to get it right mind. Just remember, its not instant heat like from a rad there's a lag getting the heat into the slab, but once there its easy to keep and maintain so the most efficient way to run it is to never let it go cold (obs in the winter, not the summer). As others have said, if you plan on thick carpet, maybe think again, I had oak boards throughout, worked a charm and feels lovely under foot.
