Description

technical field [0001] The invention discloses a photovoltaic energy storage type electric heating floor heating system, which belongs to the technical field of heating devices. Background technique [0002] Floor heating is the abbreviation of floor radiant heating. It is a heating system that lays the heat medium under the ground and uses the ground as a radiator. With the development of technology and the improvement of people's heating quality, the current floor heating gradually adopts the common laying of the ground and the ceiling. . [0003] From the heat medium, it can be divided into water floor heating and electric floor heating. From the pavement structure, it can be divided into wet floor heating and dry floor heating. The dry floor heating does not need to be backfilled with peas. In summary, electric heating has the advantages of low failure rate, maintenance-free, quick and economical installation, and can replace traditional heating methods with high energy...
