SunGrabber Hot Water Heater System Options

Anti-Scald Valve	Additional Solar Collectors	Dual Storage Tank
Adds additional protection against accidental scalding hot water getting to your faucets. Adjustable maximum hot water between 120°F and 145°F.	Additional solar collectors are available to increase the heating capacity of your system. The drainback tank is capable of accommodating 72 sq ft of collector surface area. If additional collectors are added to the system and the total solar collector surface area exceeds 72 sq ft, an additional drainback tank must also be added.	A second tank can be added to electric hot water systems for additional solar water storage. A separate solar storage tank is required for gas hot water heaters. An additional tank is particularly useful for large households or where large draws of water are taken every day.
