Purist Energy was a small business that operated for about 5 years in the renewable energy space and the development of quality solar hot water heating systems. We designed several packaged solar hot water appliances for residential and commercial applications.
Our flagship product, the SPS-2-AC is a closed loop solar pumping station that includes all of the major components for operating a solar hot water heating system.
Dual pumps, a highly efficient heat exchanger, a PC enabled differential temperature controller and required safety components are ingeniously packaged in a compact and attractive aluminum enclosure.
After sale of about 500 units, we determined that the business model would not support a sufficient margin to be viable. It was a great product and we hope and expect that those units are still collecting free energy from the sun!
