Fundamental to the system is the Aquafloor PE-MDXC underfloor heating pipe which is a multi-layer pipe with integral oxygen barrier layer. This unique pipe is extremely flexible and yet can withstand the rigour of construction environment. The Aquafloor pipe has excellent thermal transfer characteristics providing a superior floor heating solution. Renewable energy such as heat pump and solar sources integrate very effectively with the Aquafloor low floor temperature underfloor heating system, providing optimum energy efficiency.
