   Even though the HTF contains glycol to prevent freezing, it circulates hot water from the storage tank into the collectors at low temperatures (e.g. below 40 °F (4 °C)), causing substantial heat loss. A drainback system is an active indirect system where the HTF (usually pure water) circulates through the collector, driven by a pump. The ...
