FAQs
Is underfloor heating expensive to run?
Water systems are efficient and cheap to run, especially with a heat pump. Electric systems cost more to run so suit smaller areas like bathrooms.
Can underfloor heating be retrofitted?
Yes, though it raises floor height. It is easiest during a renovation or new build.
What floors work with underfloor heating?
Tile and stone are ideal. Engineered wood, laminate and some vinyls work too, but check they are rated for underfloor heating.
