Standard Water Heaters
Any standard water heater can become a solar storage tank with our solar water heating retrofit package. The image to the left shows standard water heaters retrofitted to become solar water heating systems ready for connection to the solar collector.

Drain-back Tanks
The Solar Water Heating Retrofit can also be installed on a drain-back or glycol system tank. Optimum drain-back tanks have 4 ports with built in solar dip tubes and sensor wire. These tanks are also available with a heat exchanger coil wrapped around the interior wall of the tank. Available in 10 and 20 gallon capacity.

Expansion Tanks
The expansion of heated fluids in a closed system can result in unsafe pressure inside the storage tank. Water heater manufacturers and plumbing codes require the installation of an expansion control device if a backflow preventor, pressure reducing valve or check valve is installed in the domestic supply line. Our expansion tank is NSF 61 approved for that purpose. A polypropylene liner resists corrosion and ensures long life.
