Under floor heating
Modern underfloor heating systems use either electrical resistance elements (“electric systems”) or fluid flowing in pipes (“hydronic systems”) to heat the floor. Either type can be installed as the primary, heating system or as localized floor heating for thermal comfort. Electrical resistance can only be used for heating; when space cooling is also required, hydronic systems must be used
With a water-based underfloor heating system, a series of pipes connected to your boiler circulate warm water throughout the floor to heat the space. Alternatively, you can connect the water underfloor pipes to a solar water heating system. (Thermal Store)
Because the heat emitted from an underfloor system is more evenly distributed than a single radiator, the system can use water at a lower temperature. So it’s a more efficient way of heating your home.
