What is the difference between heating with gas and a heat pump?
With gas heat, gas is burned and generates heat to heat your pool. With a heat pump, heat is transferred from the surrounding air to the pool water by drawing the humidity and converting it to heat. Gas heaters can operate in almost any climate, and at almost any time of the year. Heat pumps must have heat available in the air before they can heat the pool, so they typically work in temperatures in 55 degrees and up.
