This  Solar storage tank is specially designed to be compatible with direct solar heating systems. Rigid, polyurethane foam insulation keeps heat in the tank. The tank meets or exceeds the most demanding energy efficiency standards without an extra insulation blanket.

The electric element assists the system only when the solar energy cannot maintain the desired temperature or during periods of peak demand. Automatic temperature control thermostat keeps stored water at desired temperature. Our 80 gallon unit has two internal heat exchangers for systems that use heat transfer fluids.
