The bath bag uses 304 stainless steel corrugated pipe with high thermal conductivity as the heat transfer medium. On the basis of strengthening the heat exchange efficiency, it is reasonably and evenly distributed inside the product, while the external one is made of PPR engineering plastic material with excellent corrosion resistance, wear resistance and compression resistance and excellent thermal insulation, which greatly improves the product performance and service life. As for the bathroom floor, tap water enters into the inner cavity of the heat exchanger, and people stand on it. The waste water after shower flows through the surface of the heat exchanger evenly through the holes on the panel. The heat energy contained in the waste water is transmitted to the cold water in the inner cavity through the tube wall of the heat exchanger, which greatly increases the temperature of the cold water. Then, the heat transfer process is continuously circulated through the water heater or water mixing valve through the outlet of the heat exchanger, so as to reduce the heating power of the water heater or the hot water consumption in the water mixing valve, thus achieving the purpose of energy saving.
