Solar Domestic Hot Water is a great technology that everyone with sun should take advantage of. Solar Hot Water Heating gets a bit more complicated in New England because you need a large collector to compensate for only 4 hours of sun per day in the winter. That is, when we get sun at all. So you build this big collector to cover 40 or 50% of your heat load in the winter, but in the summer you now have a tremendous amount of hot water that you need to dump somehow.
Imagine how cool it would be if you could capture all that summertime heat and store it for winter. Well this is now a very real option. The TSS storage tank pictured above is a custom built 3200 gallon, 13” thick foam tank designed specifically for storing hot water for extended periods of time. Not only do you go into the heating season with a full “woodshed” worth of heat but the evacuated tube collectors continue to add more heat on every sunny day throughout the heating season. 
The solar collector portion of the system is much smaller then the traditional approach and the entire system is managed with a sophisticated web based control tool developed specifically for this tank system.
This particular tank has been placed in  a custom built spot in the foundation of a new house under construction.

Seacoast Energy Alternatives became a TSS dealer more than a year ago, in anticipation of the release of this product. We expect it to revolutionize the solar heating industry.
