150W Combymat System

150W heating mats for laminate, engineered wood floors or other coverings if combined with Overlay Boards.

150W Combymat Heating Mats

A versatile underfloor heating mat designed to be used beneath quality floating laminate and engineered board floors. There is no requirement to cover the mats with an additional levelling compound or moisture barrier, saving on build height and costs. 

If Overlay Boards are installed above the Combymat system carpet, vinyl, linoleum and bonded board floors can be laid directly on top, as long as the combined Tog rating is no more than 1.8 Tog.

The Combymat features an aluminium heat dissipation layer, which creates an even heat spread across the whole floor with no cold spots. 

When used with a Heat Mat thermostat they provide a fast reacting and economic to use heating system.

Combymat System Features

  • Designed to provide floor warming in all rooms, and sole source heating in well-insulated areas
  • Ideal for use beneath floating laminate and engineered floor boards of up to 18mm thickness, using the traditional tongue and groove/click system as the joining mechanism
  • Integrated earth shield within the cable (unlike carbon films)
  • Dual conductor system, only one power lead per mat
  • Easy and fast to install 
  • Simple cut and turn design offers many advantages over panel systems and speeds up installation
  • Must be installed with 6mm foam insulation boards
  • Use aluminium tape to cover any loose cables and secure the mats
  • A large range of standard sizes which can be mixed and matched to ensure a perfect fit
  • Supplied with a Lifetime Warranty
  • 17th Edition compliant without any additional earthing required

Selecting the correct sized heating mats

To start with you will need to calculate the free floor area (FFA). To calculate the FFA you should measure the room to find out the total floor area. You should then subtract from this any areas where kitchen or floor-fixed furniture will be placed, or where furniture without an air gap beneath it will be positioned. Once you have taken off these areas you have your FFA. For rooms of up to 8m2, we recommend choosing a combination of heating mats which cover roughly 90% of your FFA, and for rooms larger than 8m2 we recommend covering up to 93% of the FFA.

Combining multiple units

Combymats are designed to be laid together with other Combymats to ensure the perfect fit every time. The mats are wired into the thermostat or junction box in parallel.

Simple and speedy installation

Heat Mat Combymats are incredibly simple to install and in large areas can take half as long to fit as a carbon or ribbon panel system. The mats can be cut and turned to ensure they fit the room perfectly, and for particularly complicated areas the cable can be stripped from the mat and laid as a loose cable. Aluminium tape must be used to cover any loose cables and also to secure the mats.

Sub-floor surfaces and insulation board

Heat Mat's 6mm Combymat insulation which must be installed beneath the system offers a good trade off between build height, cost and insulation value. For particularly badly insulated areas we recommend laying Heat Mat structural thermal insulation boards beneath the 6mm insulation layer. If there is a risk of moisture rising from the floor below you must install a damp proof membrane beneath the insulation.

Laminate and engineered board

This system is designed for use beneath quality floating laminate and engineered board floors between 10 and 18mm thick. You should always check with the supplier of your flooring that it is suitable for use with electric underfloor heating laid directly beneath it. Boards with a plastic insert between the end joints can experience more movement than standard flooring. If this is a concern Heat Mat Overlay Boards should be used.

Other floor coverings

If Overlay Boards are installed above the Combymat system carpet, vinyl, linoleum and bonded board floors can be laid directly on top, as long as the combined Tog rating is no more than 1.8 Tog.

Energy efficient solution

Combymats are almost 100% efficient at converting electricity into heat and they can easily be powered by locally generated electricity from either photovoltaic or wind power sources. When used with Heat Mat’s intelligent thermostats they form an energy-efficient system, and they are also suitable for integration into a home/building automation system.

Wiring

Heating mats must always be controlled by a suitable electric underfloor heating thermostat, with floor temperature limitation. Heat Mat thermostats are rated to 16 Amps, and if a system exceeds this loading a suitably rated contactor should be used. The circuit must be protected by a 30mA RCD and suitably rated fuse or circuit breaker. The effectiveness of the earth screen must always be checked before installing the final floor covering or overlay boards.
