12mm underfloor heating pipe is used in combination with low profile overlay panels to offer an easy solution for existing homes considering wet underfloor heating. With an overlay system, almost anyone can have underfloor heating!
An overlay system (also called an overfloor system) involves laying pre-grooved panels onto the existing floor then laying the 12mm pipe into the preset grooves. The low profile system is a quick and easy solution and requires no excavation of the floor, with the main requirement being to have at least 16mm of floor depth available, plus height for the flooring.
Due to the nature of the thickness of the pipe, 12mm pipe cannot generate as much heat as standard 16mm underfloor heating pipe will but this heat loss is compensated by using closer pipe centres. Instead of your installation using the recommended 200mm centres, 150mm centres will generate ample heat for a very comfortable and efficient heating system.
