A heat pump uses nature’s ‘free heat’ from the air to heat your pool water. It applies the same principle used in refrigerators and air conditioners with technology adapted to pools and spas. A heat pump can even pull residual heat from cool air. Electricity is only needed to transfer the heat, not to create it! It is significantly less expensive than gas or electric heating. This makes a heat pump the most economical, safe and trouble-free way to heat your pool.
