Description

technical field

The invention relates to a floor heating system, in particular to an intelligent thin self-limiting temperature electric floor heating system. The electric floor heating system is suitable for newly built and renovated residential buildings, tall public buildings, swimming pools (pavilions), outdoor snow melting, heat preservation sheds, etc., especially for fine decoration and existing building renovation projects.

Background technique

In the prior art, the floor heating system mainly adopts low-temperature hot water floor radiation heating. Low-temperature hot water floor radiant heating technology (referred to as "floor heating" or "floor heating") is a new type of heating technology developed in China in the past ten years.
