Taco Flo-Checks are used in a forced hot water heating system to prevent gravity circulation during periods when the boiler is hot but the space heating zone is not wanted. This makes it possible for the use of the heating boiler to maintain domestic hot water year round. In systems with multiple circulator zones, Flo-Checks allow heat to flow only into the zones that are calling for heat.
