The pump system is equipped with an adjustable timer plus an aquastat that controls pumping cycles and water temperature respectively. Therefore, you will be saving a lot of money since the amount of energy needed to maintain a hot water supply is significantly reduced. That’s what makes these models one of the most energy-efficient pumps.
