With a heat exchanger, you can make the most of the hot water from your home’s heating system to heat your pool water. Pool water is easily heated by your home heating system (heat pump, geothermal, gas or oil heater, etc.) Therefore, energy consumption and heating performance are totally dependent on the type heating system you are using. It is easy to install and offers an excellent solution that is able to harness the power of your heating system. However, only choose this solution if your heating is economical. Also, you should know that this system only works in pools that are close to your home.
