Electric Underfloor Heating Mats

The heated floor mats are ideal for all areas of the home including living rooms, kitchens and dining rooms. The electric heating mat comes in 3 different power outputs; 100w, 150w and 200w.

Our sticky mats offer a reliable, efficient and effective solution that can work with tiles, vinyl and many other floor coverings. Our heated floor mats are ideal for use in areas such as bathrooms, kitchens and conservatories in both new build and renovation situations.

Our range of high quality premium electric heating mats will ensure that your heating system is both efficient and effective. Easy and quick to install, totally safe and easily controllable with a choice of manual thermostats, programmable thermostats, touchscreen thermostats or Wi-Fi thermostats to choose from.

There are three power outputs to choose from, each one should be used for a different type of installation:

  • 100W mats - These should be used with floors that have a timber base. They can be used with tiled floors or vinyl floor coverings.
  • 150W mats - These should be used with floors that have a concrete base. They can be used with tiles or vinyl floor coverings.
  • 200W mats - These should be used in areas that require a high heat output such as a conservatory or rooms that have poor insulation. Again, these can be used with tiles or vinyl floor covering.

If your project is for laminate or wooden floors, you should use electric underfloor foil mats as they need to be used in conjunction with insulation boards.
