How Closed-Loop Solar Water
Heating Systems Work

A pump circulates the heated liquid anti-freeze through a copper coil heat exchanger that wraps around an 80-gallon storage tank (which we install to replace your current tank). This process transfers the heat to the potable water in the tank.

During clouds or rain, an electric back-up heating element in the tank automatically kicks in to keep a consistent supply of hot water.

Typically, solar water heating systems provide hot water approximately 80% of the time – meaning your current expenditure on heating water will be reduced by 80%.
