Overlay Underfloor Heating Systems - any good?

[Ferdinand]

Has anyone experience or opinions of the type of Underfloor Heating which are put on top of a suspended wooden floor?

 

eg This one from Polypipe says it sits in a 18mm depth, and a "housepack" for a 50 sqm heated area 5 zone area works out at about £2.5k. Though of course it needs insulation below and a floor base above.

 

Are they:

 

1 - An excellent product.

2 - A good product but with compromises.

3 - The spawn of the devil.

 

This is part of the gas free rental conversation, but I thought a separate thread was merited.

For me, thoug this seems pricey, it may be a good way of getting rid of rads altogether, which can then potentially be connected to a wet ASHP. My need is to do it properly, and then more or less leave it alone for 15 years. Also, ufh does have kudos in the rental arena.

 

Any views - especially @Nickfromwales.

 

Cheers

That’s expensive compared to the same thing from Wunda that includes the EPS panels.

Thanks.

 

Are there any particular issues with the thin layer and spreader plate approach?
