Thermogroup | Thermoscreed Loose Wire Screed Heating Kit 116m 2100W | 240V IP67
The Thermogroup 3061TD is a loose wire in-screed underfloor heating kit rated 2100 W at 240 V. It supplies 116 metres of heating cable at 18 W per linear metre. The 3061TD covers 9.6 to 11.7 square metres of floor at the 200 W per square metre design density. The cable is 5.5 mm thick, carries an IP67 rating, and ends in a 3 metre cold tail.
On a new build the floor heating has to hit the output the room was designed for, and screed depth varies from job to job. The 3061TD is a loose wire cable, so the installer sets spacing on site to match that figure. Spacing runs from 5 cm to 11 cm, and 9 cm gives 200 W per square metre. The cable goes into 20 mm to 50 mm screeds and fixes down to the substrate before the pour.
Rough-in follows a set sequence: mains power lands at the thermostat position, then two 20 mm conduits run down to the floor. One conduit takes the cold tail, the other takes the floor sensor. The kit carries the dual thermostat, floor sensor, sensor conduit, cable monitor and a 25 m roll of fixing tape. Insulation is the only item not supplied in the kit.
Features
- 2100 W heating output — the 3061TD delivers 2100 W into the screed once the thermostat calls for heat.
- 116 metres of cable — the kit supplies a single 116 metre run of Thermoscreed loose wire heating cable.
- 9.6 to 11.7 square metres — the 3061TD is sized to heat a floor area of 9.6 to 11.7 square metres.
- 18 W per linear metre — the cable puts out 18 watts for every metre of its length.
- Adjustable cable spacing — spacing runs from 5 cm to 11 cm, so output per square metre is set on site rather than fixed at the factory.
- IP67 protection rating — the heating cable carries an IP67 ingress protection rating.
- 28 degree floor limit — the floor sensing thermostat regulates floor temperature to a maximum of 28 degrees Celsius.
- 3 metre cold tail — each cable carries a 3 metre cold tail for the run back to the thermostat position.
- Single ended conductor — the heating cable uses a single ended conductor type.
- PVC protective coating — a PVC coating over the heating element protects it during installation.
- Lifetime cable warranty — Thermoscreed heating cable carries a lifetime warranty, backed by manufacture in the United Kingdom.
- Screed depth limit — the 3061TD suits screeds from 20 mm to 50 mm thick and is not made for thicker pours.
Where to use
- New build screed floors — the 3061TD goes into the screed layer on new slabs, where floor height build-up is being set from scratch.
- Sand, cement and flow screeds — the cable suits sand and cement, anhydrite and flow screed mixes.
- Rooms in constant use — in-screed heating warms and cools slowly, which suits living areas and open-plan spaces running most of the day.
- Primary or supplementary heat — the 3061TD carries a room's main heating or tops up an existing system where the building is adequately insulated.
- Timber, carpet and vinyl — the finished screed takes almost any floor covering over it, including wood, carpet and vinyl.
- Insulated substrates — fixing the cable onto insulation board is the recommended build-up beneath the screed.
- Renovation screed pours — the cable also suits renovation work where a fresh screed layer goes down over an existing substrate.
The 3061TD is not for screeds over 50 mm thick, or for screed depths under 20 mm. The cable must finish fully covered by a cement-based product, and it cannot operate in a void. Thermoscreed suits primary and supplementary heating only where the property is adequately insulated.
