Hot2o System Options

Anti-Scald Valve

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

Additional solar collectors are available as add-on kits from FAFCO. The drainback tank is capable of accommodating 72 sqft of collector surface area. If your total solar collector surface area exceeds 72 sqft, you must add an additional drainback tank as shown.

Dual Storage Tank Option

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.
