Quality Pool Manufacturing has been in business since 1982. Based out of Clio, Michigan, the company manufactures and distributes pool and spa heating systems. Quality Pool Manufacturing produces an ingenious machine called the Heat Swapper. The unit takes heat generated by an existing water heater or boiler and transfers it to another liquid commonly used by a non-salt chlorine generator system in a pool or spa. As the spa or pool water passes over the coil, the heat is transferred, but does not mix. You will be amazed at just how much hotter your pool or spa water will get when installing a heating systems from Quality Pool Manufacturing.
