I notice that you say this system has no pumps or bubblers, so how is overheating handled? Also, what about freezing?

Thanks for the questions. The tank has a temperature and pressure valve that releases hot water to protect it from overheating. If the system is over-sized for the consumption, or in an area with especially good solar resources, we have various active and passive overheating recommendations on our website. As for freezing, the only part of the system that is susceptible is the plumbing between the tank and the conditioned space. We have passive (freeze protection valve) and active (re-circulation pump) methods to handle that, as well. Any more questions just let us know.

Would this system work for an outdoor shower? What are the dimensions?

Absolutely works for an outdoor shower. If you want to use it just for the shower then you could plumb the cold water from a hose bib and have the hot go straight to the shower. Footprint is 4' x 7'. Email or check our website for diagrams thesunbank dot com.

I realize that south facing is usually best. but would flush mount on an east facing pitched roof in arizona still provide decent performance?

An east facing roof in Arizona will perform better than a south facing roof in most of the country because of how much sun you have there. You'll get better morning production than you would with a south facing system and not quite as much production in the afternoon. Many of our customers have systems installed on east and west facing roofs.

battery powered with no need of batteries? how does it work?

Because it is solar, Amazon's back end assumes it must be solar electric - they don't let us edit the "battery powered." There are no batteries, the water is heated by the sun. https://thesunbank.com/how-it-works/

Free hot water. Nothing like it.

I just finished a Do It Yourself Sunbank install. I did two 40 gallon units hooked in series. A very doable project. These panels and system DO work. I had 175 Degree hot water that is too hot. I have since installed a 15 Watt solar panel and 15 Watt solar pump and that works flawlessly. That flows the solar heated water through the two 40 gallon Sunbank tanks and the 20 gallon tank that the solar panels feed. (See photos) So far it seems like a pretty good system.NOW, THREE YEARS LATER: System is still FLAWLESS. Same little pump and solar panel. No leaks. Lots of hot water. Most every day the same little fist sized pump pushes the 100 gallons of solar heated water through the system. LOVE IT!
