Underfloor heating such as the excellent Devimat system gently warms the tiles from below and contributes to the overall central heating of the home. The system is available in 14 different size options ranging from 1.0m² to 12.0m². We also offer the Devireg 550 themostatic control system which offers the user ultimate flexibilty. Note: We only recommend the 100 watt variant of Devimat for use with Tilesafe .  We have carried out thorough testing in conjuction with the Tilesafe membrane and Devimat is perfectly safe to be installed right up to the drain in the showering area. What's more, running costs are generally lower than you might expect!
