Retrofitting Underfloor heating

AAZ

We are in the process of getting new tiles for ground floor and want to install underfloor heating. The boiler is 11 year old so may be in some time we may get heat pump as well. What are the best company to go for UFH. Any advice much appreciated

Something like LoPro from Nuheat would be something I would be looking at.   We have UFH but it was put in when we converted the barn so I have no experience of retro fit.

These guys are very clever.  They retrofit it
into existing screed. Only takes a day or so.

thats clever, but only going to work for a few houses that already have a properly insulated floor.

That is indeed clever, I do not want to raise the floor level. `I will give them a call and see

What does properly insulated floor means, how can we check that ?

When was your house built? In properties before about 1990 they didn't bother putting any insulation under the screed.

If you try and install underfloor heating in the screed without any insulation below, then you'll lose a lot of heat into the ground below.

Depending on the age of your house, and general insulation and air tightness properties, you may not get enough heat out of an underfloor heating system. Best to use a company who can undertake proper heat loss calcs.

I used the prowarm loflow boards. Raised the floor level by almost 20mm, but got me underfloor heating, and avoids radiators on the walls. 

The kit cost about £950 but it was a bit of a faff to lay the boards, put the pipe round and tile over. Worth it in the end.

Well then it is not insulated, house was built in 1970, do you have a recommendation for a company who can do heat loss calculation ?

20 mm is not bad, how is the heating, did you go for tiles or laminate ?
