The pipework has been installed in the underfloor plates that were installed. It seems strange to think that this is going to heat the upstairs of the house. It hardly seems enough, but when you think about it, these plates are really just a massive radiator – albeit installed under the carpet.
The first floor bedrooms will have carpet and it is possible to install “low tog” underlay and carpet that will help transmit the heat through the floor. Often underfloor heating is associated with solid floors, however, I am assured that it works well with both timber and carpet. We will just have to see how it works.
