For those who want an energy efficient heating system without needing to dig up the floor, the Warmup DWS400 Loose Wire Underfloor Heating Kit is an ideal choice. The 400W kit provides enough wires and heating elements to cover a room between 2.5 and 3.4 square metres, and has a single connection lead for a simpler installation. An ultra thin, dual-core heating element provides heat without raising the floor level, and double insulated, 2mm wires carry the energy around the room. A programmable thermostat controls the heating, providing Active Energy Management along with graphs of current usage and suggestions on how to heat the room more efficiently, saving you up to 10 per cent on energy bills. A lifetime warranty and installation guarantee offer complete piece of mind, too.
