Replacing Thermosiphon Solar Water Heaters

Sunbanks have been replacing flat plate thermosiphon type solar water heaters for years now, and we have worked with installers to develop a special package to make these replacements plug and play.

This package included our WiFi enabled Smart Home Controller that data logs and graphs the temperature in your Sunbank and allows you to check the temperature and turn on and off the heating element from anywhere in the world. We’re happy to walk customers through this process and to let you know why the Sunbank, also a passive thermosiphon system, is the right choice for your next solar water heater.

Here are five reasons that you may decide to install a Sunbank:

Your home is already plumbed for a passive solar water heater. For many installations, getting the water pipes from the roof to the conventional water heater or into the home is the biggest challenge. With that done, installing a new solar water heater is much easier.
The Sunbank heats with evacuated solar collectors whereas many other thermosiphon systems use flat plate collectors. We like both technologies, but for different reasons. Flat plates are often less expensive and not as well insulated, so they perform better when it is hot outside but are not as efficient in the winter. All solar water heaters produce plenty of hot water in the summer, so the increased efficiency in the winter is more beneficial. You can find more information about this, including efficiency graphs on this page.
Sunbanks are made from all corrosion resistant stainless steel and aluminum. We know that installing a solar water heater can be expensive, so we want your system to last as long as it can.
The Sunbank heat pipes go into a stainless steel manifold, essentially surrounding them with water to be heated. This is a very efficient way to transfer heat, as there is nowhere for the heat to go but into the water tank.
At Sunbank we pride ourselves and continue to work toward an easier installation. This opens up the market to DIY installers and cuts down on professional installation cost. Evacuated tubes with heat pipes are easy to install.

Easy Replacement, Cost Effective

Sunbank solar water heaters are SRCC certified and eligible for the 30% federal tax credit. This means that you can receive a tax credit on the total cost of the installed system, and can help you start saving even quicker.
