How quickly will my tiled floor warm up with underfloor heating ?
A This depends entirely on what material your sub-floor is made up of; a concrete base will be extremely slow to warm-up without any insulation barrier between the underfloor heating system and the concrete. We recommend the use of Marmox tile backer boards as the insulation barrier. If the sub-floor is floorboards these need to be covered by ply screwed fixed at 300mm centres.
