underfloor heating in 1811 house?!?

[caz26]

Dear All,

Thinking ideally we'd like to install underfloor heating to our freezing house. Having a wall removed downstairs (with permission) to make a larger kitchen so thinking underfloor heating through this and the hallway.

Our house has combed cellars under the entire floorspace and our original floors were flags; although many unfortunately broken-and screed laid over by previous owners-now carpeted. Wondering if underfloor is possible in this situation? What sort of total depth would I need to see if this is even a possibility. Assuming I can remove old floor down to top of cellar can I lay insulation on this and go from here?

Also, is underfloor a decent option in an old sanstone draughty number that was designed to breath!

Any help/suggestions welcome,

Thanks in advance,
Stephen

You need a good structural engineer or architect with experience of your construction to advise whats likely to be possible.

Most UFH systems need 50 mm of insulation and about 40-50 mm of screed with the pipes embedded.

I would doubt you will get enough heat output for your house from UFH so make sure thats fully checked before you start.
