Brief Introduction on Solar Wand

The Solar Wand allows standard hot water tanks to be adapted quickly and easily for solar heating. The Solar Wand is a double walled heat exchanger that fits into any full size, 40 gallon and up, domestic hot water tank. It screws into the outlet port of a standard hot water tank. It provides a new hot water outlet and new solar collector fluid input and output connections. The Solar Wand has about two square feet of heat transfer surface inside the tank. The solar collector fluid, usually a mixture of propylene glycol and water, is isolated from the hot water by two copper walls and the space in between is vented outside of the tank. SRCC OG-300 Certification still pending.

The Solar Wand allows the solar system installer to use the existing hot water tank and a single pump to circulate fluid from the solar collector to the Solar Wand. Hot water tanks with built in heat exchangers are not usually available at water heater retail outlets.

When a new tank is needed, the Solar Wand can easily be transferred from the old tank to the new tank during installation. Homeowners can install the Solar Wand and solar collectors themselves however, professional installers are recommended to save time and effort.
