Solar Expansion Tanks

A solid, reliable solar expansion tank is a critical component of any pressurized solar hot water or solar heating system. The solar expansion tank provides a safety buffer as the heat transfer fluid (typically a combination of water and SunMaxx Glycol XT) expands as temperatures within the solar loop of your solar thermal system increase throughout the day.

If you have any questions in choosing the right size solar expansion tank for your new solar hot water system, or to replace an aging expansion tank in your existing system, please contact one of our solar professionals today.
