Screws into your Standard Hot Water Heater!
The Butler Sun Solutions Solar Heat Exchange Wand (Patent Pending) allows readily available, standard hot water tanks to be adapted quickly and easily for setting up your solar assisted hot water system. The Solar Wand is a double walled heat exchanger that fits into any full size, 40 gallon and up, domestic hot water tank. Its unique design allows it to 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 almost 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 your hot water tank fails after many years of normal use, simply transfer the Solar Wand from your old water heater tank to your new water heater during installation. Not only will the professional installers save time and effort, but the no-hassle design allows even the do-it-your-selfer/homeowners ton install the Solar Wand to save themselves money.
