Underfloor heating is often thought of as a luxurious addition to a home, and in many cases it can be a low carbon heating measure. If it’s a “dry” system using electrical wires, you’ll have to use electricity for it to work, while a “wet” system raises the temperature of water flowing through pipes under the floor to heat it. However, it all depends on the source of the energy used to heat the wires and the water - especially with a water-based system - and you’ll need to take into account the increased time it takes to heat a room using underfloor heating rather than radiators, too.
