One of great things about having Building Energy design our domestic
solar hot water, besides their professionalism and dependability, was
the extra effort they took to train a plumbing company in our area to
install the system. It not only saved money but has far reaching
benefits in the community. Everyone should get solar. It pays for
itself and it’s good for the planet.” Rebecca Purdum and Tom Moran
