Good Afternoon. If you are looking for a reliable manufacturer of pool heating equipment, I recommend you to pay attention to Raypak. They specialize in producing quality and efficient heating systems that will ensure a comfortable pool water temperature. I used their pool heater myself last year and the results were impressive - the water warmed up quickly and we were able to enjoy swimming even on chilly evenings. Here's their contact number if you have any questions:
