Open Direct SystemDomestic Hot Water ModeWarm water comes out of the tank and into the fixtures. Cold water from the well or from the street must replace the water that was used.

This prevents stagnation of the water within the tubes during the summer and provides some free cooling Animation illustrating the functionality of an open direct system's heating mode.
