Plan to do a main bathroom refurb soon myself, and was wondering what sort of cost is involved in UFH, so I will be watching thread with interest?

Roughly same size in sq metres, just more square shaped (I'm sure won't affect price).

These "mats" come in rolls of plastic and and the element for heating them is like a waveform from top too bottom too top again. You cut the plastic too suit each bathroom leaving the element all connected. Only draw back is when the element burns out ( they all do) only way too fix the heating is rip the flooring up! I'm not aware of any good stable brand as all the ones I've wired up in the past have burned out in a matter of years

If there is a rad (I'm presuming boiler / water) then why not just use a water based system?

Lift floorboards and install a few qualplex loops fed from a stat valve.

Woukdnt it take hours for qualpex too transfer heat through floorboards-chipboard- adisive - tile.?

I don't think qual is built too lose heat but actually keep it in.

True, copper would be better at losing heat but more difficult to install as a DIY job.

I have a towel rail in the ensuite fed under floorboards / 6mm ply and tiles with QP and it warms the floor, wasn't meant to and is not looped but works and is a bonus!
If I'd known I would have put in a few circles around the room.

I agree it would be slower to heat but it would beat ripping up the floor every few years to replace the electric one.

How do you mean not looped?

Steve

I mean it was just fed straight under the floor to the towel rail, not sent in a loop around the room.

It will lose heat quick enough. Put your hand on qualpex that has 80 degree water in it, and you will feel the 80 degree temperature quick enough, so it does give out heat from its water.

It needs insulation around it if there is anything that will quickly conduct heat away from it, or on a long run.

Yea I can notice that in my own house where the pex is running to rads.

Thanks for all replies.

Floor is concrete - ground floor - so will talk to plumber if plex is an option.

In terms of Mats - assuming they all burn out. Is there any brand that is generally more reliable than another that someone could recommend.
Likely will not go down this route now but good to know in event Plex is not an option.

If the concrete surface is the finished level apart from tiles etc, then the mat will probably be the option used.
