1. Stainless Steel Material: The swimming pool heat exchanger is made of high grade anti corrosion stainless steel, anti rust and salt water resistance, . 2. Constant Temperature: It is heated by water, and the cold water is turned into hot water by heat energy, which is heated circularly. It is suitable for the simultaneous use of solar panels (shipped without solar panels). 3. Maximum Heat Exchange: Specially designed built in flow limiter aims to minimize the pressure loss in the heating system and ensure maximum heat exchange. 4. Space Save: Equipped with stainless steel fixed bracket, easy to install and use. Small and compact size, light weight. Minimum installation space is required. 5. Application: The heat recovery pool heater is suitable for swimming pools, spas, hot tubs, solar, hydraulic heating, oil cooling, heat recovery, snow melting, etc.
