Description Rugged and Durable: It is made of polished and sanded 304 stainless steel, so it is water-resistant and has a long service life, ideal for chlorinated or saltwater pools and spas. Pipeline Heat Dissipation: It can speed up the heat exchange rate and ensure the maximum rate of heat exchange. Protective Housing: A high-quality 304 stainless steel shield can protect the heating element from direct contact with people or animals, to protect your use of safety. Reverse Outlet & Inlet: The inlet and outlet are reversed, both on opposite sides, which can optimize water flow dynamics and improve heat transfer efficiency. Application It is suitable for swimming pools, spas, hot tub tray heating, outdoor wood stoves, circulating heat, forced air heating, snow melting, solar hot water, and more. It can be used with any type of pool water, whether treated or salt water.

Exceeding the recommended chloride concentration or direct use of the chlorinator may result in stainless steel pitting. Titanium pool heat exchangers are recommended for use in environments with high chloride concentrations. 4.Please note that the heat exchanger should always be installed in reverse flow and should be installed downstream of the filter and pump equipment. It must be an auxiliary equipment for boiler water and take usual precautions to prevent air lock. 5.People must not be in the water while the heat exchanger is working. 6.Please do not put 2 heat exchangers into a swimming pool at the same time. 7.The product requires a heating circuit to work properly and a thermostat circuit to ensure a continuous thermostatic effect.
