Thermogroup | Thermonet Underfloor Heating Kit 800W 8 x 0.5m | 5220A Ice White Thermostat
The Thermogroup 112008T is a Thermonet underfloor heating kit covering 4 square metres, supplied with a 5220A programmable thermostat in Ice White. The 112008T mat measures 8 by 0.5 metres and draws 800W at 3.33A on 240V. It is rated IP68 and installs under tile or in screed up to 50mm thick.
Floor heating is buried work: once the tiles are down, a damaged element means lifting the floor. The 112008T is a single ended mat with a 5m cold tail, so one cable returns to the thermostat. The element is TwistedTwin cable on self-adhesive mesh, and the mesh is cut to turn the mat, never the cable.
Three resistance tests are specified: before laying, after sticking down, and after the floor finish. Each result goes on the customer handover form, which the homeowner needs to register the lifetime warranty. The kit includes a 6025 mat alarm that sounds if the element is damaged during screeding or tiling.
Features
- Covers 4 square metres — the 112008T mat runs 8 metres long by 0.5 metres wide.
- 200W per square metre — the higher output density suits rooms that lose heat quickly.
- 3.33A current draw — the 112008T pulls 800W on a 240V supply, setting the circuit and RCD requirement.
- IP68 rated — sealed to IP68, which covers continuous immersion in the floor build-up.
- TwistedTwin cable — stress free cable construction with zero electromagnetic field.
- Single ended mat — a 5m cold tail returns to the thermostat, with no second cable run back.
- 3.5mm mat thickness — the mat adds 3.5mm to the floor build-up, and the cold tail is 4mm.
- 28 degree ceiling — maximum floor temperature is 28 degrees Celsius, regulated by the floor sensing thermostat.
- 5220A programmable thermostat — the 112008T ships with the Thermotouch 7.6iG in Ice White.
- Mat alarm included — the 6025 alarm monitors the element for damage while the floor finish goes down.
- Cable cannot be cut — the yellow heating cable must never be cut or shortened, only the blue mesh.
- Lifetime mat warranty — lifetime on the heating mat and three years on the thermostat.
Where to use
- Bathroom floors — the 112008T is safe under a tiled shower, helping dry the floor and reduce mould and grout discolouring.
- Screeded floors — suits sand and cement screeds from 20mm to 50mm thick, fixed over insulation board.
- Direct under tile — tiled over using a full bed of flexible tile adhesive rather than dot and dab.
- High heat loss rooms — the 200W per square metre output suits rooms prone to losing heat.
- Compact wet areas — the 112008T covers 4 square metres, sized for an ensuite or small bathroom floor.
The yellow heating cable must never be cut or shortened, as this alters the resistance and will burn out the element. Do not lay the 112008T under floor mounted fixtures or solid based furniture, and leave it unpowered for two weeks while the adhesive or screed cures. Nothing with a tog rating above 2.5 should sit on the finished floor.
