Today it has become very common to renovate your kitchen, bathroom, laundry room, or hall. Tiled floors are popular and most people then opt to install underfloor heating in order to avoid a cold floor. It is not difficult, and is largely about finding an underfloor heating system that is suitable for your floor construction and a mixing unit (referred to as a shunt group below) to connect it to the existing system. Many people believe you can only use electric underfloor heating in small spaces. This is of course not the case, and people frequently prefer water-based underfloor heating in order to utilise the existing water system and save energy.
