Underfloor Heating - embedding UFH in existing concrete or low profile alternatives

[Roger440]

Id suggest it will be fine. 

 

Yes, i didnt want the shallow step. On the face of it, its not much, but you do notice it in use. Bizarre really, your wouldnt think that would happen.

In that it won't be efficient enough or will just not work? The company we're using are obviously fairly sure it will,  have proven track record and excellent reviews - how will it not work?

 

It will work, it won't be efficient. If you're paying good money most companies will do whatever you want. Fit a heat pump in a totally unsuitable building, no problem etc. 99% of folk would feel warm underfoot and give the company rave reviews based on the feel good factor. Noting the extra expense will come later. Do all you can to mitigate heat losses elsewhere. 

 

On here @oranjeboom excavated his whole ground floor in his existing house then built back up with insulation and a new slab with UFH in.

A typical thread on the subject, the "a lot of companies" comment echos what I said. If you want comfort and can afford it long term then UFH with limited insulation may be for you. If saving energy/the planet then maybe not. 

 

 

There's some pics on the forum somewhere of @oranjeboom when his whole house floor got dug out. Not so much in his blog here:

 

 

I've only dug down and built back up one room. Some pics of the digging and starting to build back up here:
