Multi Room Overlay Kit – High Output

Choose one of our professional overlay kits to heat one multiple rooms. These kits are designed to be installed over an existing floor and can be laid onto any solid level surface including tiles, concrete or wood and do not require additional insulation installed beneath. The high density of the boards allows for all types of flooring to be used including tiles.

These are rapid response heating kits capable of heating all rooms including conservatories, assuming heat loss calculations have been carried out to ensure adequate performance.

The overlay boards MUST be bonded to the floor using the inclusive floor adhesive and cannot be installed dry as a floating floor. Failure to follow correct installation guidelines can result in very costly mistakes. Please ensure you have read our installation guide before installing this system.
