We recently finished this two panel steamback Stiebel Eltron solar hot water system in Easthampton, Massachusetts for Todd and Cheri. Steamback refers to the method by which the solar hot water system is protected from summer time overheating. This method requires no electricity or moving parts to function making it very robust (as opposed to the "old days" where some people had to cover panels during the summer). The system will provide an estimated 80% of their hot water needs saving them hundreds of dollars per year.
