Heated swimming pool, also called indoor heated swimming pool; That is, the water temperature of the swimming pool is kept at 26-28 degrees, which is suitable for the human body. At the time of design, the water in indoor swimming pools is generally heated in various ways to maintain a constant temperature.

Indoor swimming pools usually have various heating methods when they are designed. Swimming pool constant temperature heat pump converts low-grade heat energy in the air into high-grade heat energy through the principle of inverse Carnot cycle, and heats swimming pool water at constant temperature.
