Underfloor Heating Mat Systems

Underfloor heating system which includes heating mat, thermostat, sensors and thermal insulation board plus accessories.

System includes:

  • Underfloor heating mat.
  • Thermostats: A range of thermostats are available including touchscreen, wireless and simple digital controllers.
  • Thermal insulation board (600 x 1200 mm): Consists of a rigid foam core (high density extruded polystyrene) and a cementitious hard coat.

Underfloor heating mats – 110W/160W/200W/240W:

A high-quality fast-to-fit system designed to provide energy efficient floor warming in all rooms, and a full heating system in well insulated areas. This heating mat range can be used beneath virtually any type of floor covering if covered with a levelling compound, ensuring luxurious warm floors whatever the floor finish. Heat Mat underfloor heating systems offer a versatile and fast reacting solution for a variety of buildings including new developments and period renovations.

- Features:

  • Meets the requirements of the Building Regulations (E&W) Approved Document L.
  • Will provide floor warming in all rooms, or sole source heating in well-insulated areas.
  • Integrated earth shield (unlike carbon films), allowing safe installation in wet areas.
  • When used with an intelligent thermostat, Heat Mat systems react faster, are more energy efficient and cost less to run than lower powered alternatives.
  • Design delivers minimal build height combined with a robust high-powered heating cable.
  • Particularly suitable for large areas, where loose heating cables will take longer fit.
  • When installed at 200 W/m² or 240 W/m² this system is suitable for providing a full room heating system, even in high heat loss areas such as conservatories.
  • Perfect for floor warming or room heating in standard rooms when installed at 160 W/m².
  • Alter the heat output for individual requirements – outputs from 80–230 W/m² are possible.

Underlaminate heating mat – 150 W:

An earth shielded system designed to be used beneath quality floating laminate and engineered board floors without the requirement for covering with levelling compounds. Combymats can provide sole source heating or floor warming.

  • Combine with overlay boards for carpet, vinyl, linoleum and bonded board floors.
  • No wet trade required for any type of installation.
  • Supplied with 6 mm insulation.
  • Pre-spaced heating cable for speedy installation and uniform heat output.
  • Aluminium heat dissipation layer ensures an even heat spread with no cold spots.
  • Supplied with a lifetime warranty.
