Additional feature is equipped with a solar heat exchanger connected to the storage vessel and a corrugated stainless steel coil within the tank, the Strato-Therm+ maximizes heat transfer in a solar thermal system and increases collector performance. A back-up hydronic heat source, such as a Knight boiler, ensures that the storage vessel is at a sufficient temperature to simultaneously generate domestic hot water and meet hydronic heating demands. As demand for space heating is initialized, the Strato-Therm+ acts as a hydraulic separator, decoupling the system demand from the boiler output. The cooler water in the bottom of the tank allows for greater collector efficiency and greater opportunity for solar thermal heat generation.
