Solar Water Heaters
Solar storage tanks often work in tandem with your circulator pump (in active systems) and temperature controller. Once the tank is fully charged, the temperature controller sends a signal to your pump to shut off. SolarTown offers storage tanks for active and passive as well as direct and indirect solar thermal water systems. Our tanks come in ...
