Thermoslab In Slab Heating – Cable Only

Versatile In Slab Heating Cable

Thermoslab is a brilliantly versatile, robust 7mm thick underfloor heating cable designed for use In Slab. Install the cable in the concrete slab of new builds to create an energy efficient thermal mass under your floor. To work out which heating cable is required, multiply the Square Metres of your area by 160 to give the required output (Watts).

Allow 3 cable ties for every 1m of heating cable. Thermotouch manual thermostats are recommended for Thermoslab as this is typically connected to off peak power tariffs so you cannot have a programmable thermostat as it would lose its program during the 'off periods each day

Frequently Asked Questions


Can I use my floor heating on "Off Peak" electricity?

When using in Slab Heating you can take advantage of the Off-Peak electricity tarrif as heating the slab creates a thermal mass beneath your floor that allows for a slow continuous release of heat. Under Tile and In Screed heating systems have a more rapid heat up and cool down time, therefore are not suitable to be used with Off-Peak electricity.

Can I join two or more heating cables or mats to fit a larger area?

No, the heating cables or mat cannot be joined together however two or more elements can be connected in parallel to one Thermostat. When connecting multiple cables or mats you need to ensure that the total load does not exceed the total load of your thermostat.

Can I cut the heating cable if I have excess?

No -never. Cutting the heating cable will alter the resistance and cause the element to overheat. If you cut the cable by accident please call our technical helpline for assistance.

How long does Underfloor Heating take to heat up?

Every situation is different due to the insulation value of your property, type of flooring used and the level of heating used below the insulation. An inslab heating system typically takes around 1-2 days to heat up and the same to cool down as it needs to heat the entire slab profile. Once it does heat up it becomes a very energy efficient way to heat as the slab acts as a heat bank, continuing to heat up through the room.

Is an Electric Underfloor Heating System possible with polished concrete floors?

When considering installing Underfloor Heating with a polished concrete floor, the answer is yes, this is possible! There are two options for how this can be done, using either our In-Slab or In-Screed System. Where a full slab is being poured and the surface polished, an In-Slab System can be used within this slab to heat the whole slab in a thermal mass. Alternatively, where a secondary slab is being poured and polished, then an In-Screed system can be used between the initial pour and the secondary slab, thus providing a more on-demand heating solution for your home. For further information, view our article on Polished Concrete & Underfloor Heating.
