This ground mounted EV tube system is a Drainback system, whereby the heat transfer fluid drains back into the solar tank after the pump shuts off. This design allows for the use of water as a heat transfer fluid and will always fail safe, that is, It cannot overheat or freeze. Drainback systems are superior in this regard.
