Electric floor heating cables

Warmup’s range of heating cables include systems both for new construction and renovation, from direct heating to systems that generate a higher thermal inertia.

Electric underfloor heating cables

Heating cables can be installed directly onto or into the subfloor, without the need for a mat backing. They offer great flexibility for layout design as they can be fitted around fixed objects and architectural features, making them the perfect floor heating solution for bathrooms and irregularly shaped rooms.

The spacing of the cables can be altered depending on the required heat output (W/m²). Warmup’s range of heating cables include the WIS and DWS heating cable systems and the the DCM-PRO system, which features a heating cable with an accompanying anti-fracture membrane.

Warmup heating cables range

The heating cables offer an energy-efficient floor heating solution for new-build and renovation projects. The inscreed heating cable is recommended for new-build projects as the cable is installed directly into a concrete screed, the depth of which can be taken into account during the specification stages of the project.

The DWS heating cable is perfect for installing in bathroom renovations as the ultra-thin 1,8 mm heating cable can sit within the layer of levelling compound or tile adhesive, thereby having almost no noticeable effect on floor build-up heights.

The DCM-PRO system is ideal for both new-build and retrofitting applications and has been specifically designed for use with tiled floor finishes.

The inscreed heating cable is designed for installation in a concrete screed layer, and is suitable for almost any floor finish.

Which heating cable is best?

No matter the floor finish, subfloor type or size of project, there is an electric floor heating cable suitable for any requirements.

Floor finish and subfloor type

The DWS heating cable (loose wire system) is ideal for use with stone and ceramic tile flooring and can be installed onto insulation boards over concrete subfloors.

If using a concrete floor screed as part of a construction project, the inscreed heating cable has been specifically designed to be installed within this subfloor type and can be used with a wide range of floor finishes.

The DCM-PRO system is the perfect heater to use with tiled floor finishes. It is a heated decoupling system that uses an anti-fracture membrane in which to fit the heating cable.

Floor build-up

Heating Cables offer a low-profile floor heating solution that won’t substantially raise floor levels.

The Loose Wire system is the thinnest heating cable on the market, at just 1.8mm, making it an ‘invisible’ heating system that can be installed within a layer of levelling compound or tile adhesive. The Inscreed Cable has a slightly thicker width of 6mm but is installed directly into a concrete subfloor so has no impact on floor build-up while the DCM-PRO features a system depth of 5.5mm. All heating cables should be installed alongside suitable insulation materials such as our Insulation Boards, which enhance the energy-efficiency of the system.


Room type

Heating cables are recommended for irregularly shaped rooms and rooms with multiple fixtures such as bathrooms. The cables can be laid down onto the subfloor in whatever layout is most suitable for the area, winding them around corners and fixed objects like baths and shower trays with ease.

Due to its thermal inertia, the WIS heating cable is ideal in new construction. However, If installing floor heating in regular-shaped rooms with open floor spaces, our electric floor heating mats may offer an easier solution.


Heating Cables facilitate quick installation times and can be installed with no need for specialist tools.

The inscreed heating cable must be laid within a 50 mm deep screed floor construction. The cable must be secured to the subfloor using the accompanying metal fixing strips which hold the cable in place before a cementitious screed is poured over.

heating cable installation

To install the DWS heating cable simply prime the subfloor and mark out the cable layout before placing the cable where needed, taping down into position. Always make sure to keep a minimum distance of 50 mm between the cable runs. The cable can be covered with a thin layer of levelling compound or tile adhesive before covering with the chosen floor finish.

Due to its self-adhesive backing, the DCM-PRO’s decoupling membrane can be attached to the subfloor rapidly and easily. The membrane’s castellations act as a pathway for the DCM-PRO Heating Cable, simply push the cable into position with the hands, keeping a minimum distance of 60 mm between cable runs. Once done, simply cover with self-levelling compound or tile adhesive.
