Replacing concrete floor and installing UFH
Posted 05 November 2009 - 01:27 PM
We are currently purchasing a 1917 detached house. The existing floors are concrete and we want to install a wet system due to the long term costs of dry.
Someone has suggested that 75mm is needed to fit it and the existing floor will probably have to be dug up and replaced, with the new concrete floor incorparting the pipes.
Alternatively, we could put it on the existing floor but will lose 75-100mm of height in the room and the associated problems with existing doors etc that we want to avoid.
The floor space is about 72m2.
Can anyone give an indication of:
Cost of digging up floor (is this something I can realistically do myself with Kango hire?)
Laying of new floor
Installation of wet UFH
Any help or guidance here will be gratefully received!

You would probable loose more than that. Most people recommend at least 100mm of insulation and the minimum for normal screed is 65mm. The thinnest I would recommend is a system using 80mm of insulation between 80mm deep battens with 20mm engineered wood (eg oak) floor on top. That would total 100mm and give you an oak or similar floor finish not carpet. It assumes the house is reasonably well insulated.
If you can't accept thw 100mm loss of headroom or want carpet then either take the floor up or fit rads.

Instead of screed you use aluminium spreader plates
Then as said just finished flooring over that or ply then tiles
No delays or drying time then too
