Phoenix Solar Water Heater

The Phoenix Solar is a highly efficient and extremely versatile water heater that combines an internal solar heat exchanger with gas fired back up. When connected to solar collectors, the Phoenix Solar Water Heater harnesses the power of the sun to provide ample domestic hot water while reducing energy costs and pollution. When the sun’s energy is not hot enough the gas back-up modulates and fires just enough to replace the solar energy shortage, or fires accordingly to carry the standard building load in cloudy weather. It is manufactured with super durable stainless steel materials to last longer and provide optimum heat transfer. It is up to 96% efficient with a five to one turndown ratio and suitable for both residential and commercial applications.
