[0002] Water-heated underfloor heating is a type of floor heating system that uses water circulation to heat the floor. Underfloor heating system is a shorthand for floor radiant heating system. It is called an underfloor heating system because underfloor heating itself is not a single product. Underfloor heating generally appears in the form of a system, which includes a heat source, pipes and corresponding auxiliary materials. It is one of the most comfortable and healthy independent home heating methods. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of water-heated underfloor heating.
