As said ... it all depends on the heat loss of your building / room. A passive house (with near-zero heat loss / with actual gain) can be "heated by a candle", and it's actually a problem in such places getting the heat from, say, cooking "out" of it (don't get an Aga if you have a passive house !). On the other end, a drafty 1890's victorian terrace with an EPC E will leak heat so badly - floors, walls, roofs, windows - that no efficient heating system replacement will get it warm. That the old cable-based electric underfloor heating "cooks" your feet is true (my parents "upgraded" their 1980's electric UfH to radiators around 20 years ago ... because of that as well as the running cost). That carbon-film-based electric underfloor heating with its nice and even heat distribution is a much more comfortable "feeling" is also correct. But if your heat loss notably exceeds the ability of of your heating system to introduce heat ... it won't get warm. "Wattage" ... is just a measure of heat loss / gain, Energy-per-time. If you loose heat at a rate of 1kW then you need to introduce heat at that rate to keep the room temperature the same. My advice is: Get a heat loss calculation done first, before you embark on installation of underfloor heating. The manufacturers are usually rather willing to help with that, to make sure what gets installed is suitable for purpose.

If you scroll through this link you will see my photos. I ordered this for my kitchen. My completely inexperienced contractor installed the floors over existing 50 year old asbestos vinyl. We used the Atrafloor cold weld. The seam is almost invisible and the product is water tight. Your installers are using old technology and old methods. It is very usable for a home installation. Mine have been down about 3 months old and look great. My installer also made a small measuring mistake and I ended up with a 2nd seam, but it is not noticeable at all. You cannot use the type of adhesive sold in USA it is old fashioned and old technology. Mine was not stiff at all, but I did keep it inside the house to acclimatize before installation. It is soft a pliable. Atrafloor answered all my emails.

They’re not misleading building estimates but an estimate is just that … an estimate not a firm quotation. Being in the construction industry myself we too have problems getting customers to realise just how fast materials and prices are increasing. We now only offer a 14 day validity so we can TRY and purchase at the same cost that we have allowed for in our customer’s quote. We have even been quoted a price in the morning and then when we have gone to buy the items in the afternoon they've gone up again. Perhaps you can get the shell done and then do the finishing touches when funds have been replenished. These are very difficult times for customers and traders.

Hello! I am installing a new kitchen and I have 2 completely different Sapienstone Platinum White samples! I like the one without the veining and I don’t like the other one at all. I don’t know whether to go for it or not. Does anyone have it in their kitchen?
