The invention discloses a prefabricated thin and light-typed low-temperature hot-water floor
radiation heating system, comprising a filtering device, a water mixing device, a
first class water collecting-distributing device
system, a second class water collecting-distributing device
system, a general water feeding
pipe, a general water returning
pipe, a contact water feeding
pipe, a contact water returning pipe, a heating loop, a heating pipe and a heated board. The first and second class water collecting-distributing device systems are respectively composed of 1 to N first and second class water collecting-distributing devices; each
first class water collecting-distributing device adopts 1 to N second class water collecting-distributing devices, and each second class water collecting-distributing device adopts 1 to N heating loops according to needs; the
first class water collecting-distributing device is connected with the general water feeding pipe and the general water returning pipe; each first class water collecting-distributing device is provided with 1 to N circuit branches which are respectively connected with the 1 to N second class water collecting-distributing devices through the contact water feeding pipe and contact water returning pipe; each circuit
branch of the first class water collecting-distributing device corresponds to one second class water collecting-distributing device which corresponds to one heating unit. The
heating system is comfortable, energy-conserving and environment-friendly and is provided with better heating stability and long service life.
