Heating system with heat transmission fluid distributed in finished floor boards

Abstract

A floor heating system comprising: at least one modular floor heating element, including a top surface and an opposing bottom surface linked by a series of longitudinal ducts, the longitudinal ducts enabling connection with three-point connections and/or two-point connections for coupling each of the ducts to a delivery duct and to a backflow duct, respectively, for collecting and feeding back a heat transmission fluid; a delivery duct for feeding the transmission fluid; a backflow duct for collecting and feeding back the transmission fluid; two-point connections for connecting adjacent ducts; three-point connections for connecting ducts to the delivery duct or the backflow duct; an alternated application of three-point connections with at least one two-point connection which allows the reversal of the direction of the heat transmission fluid.
