It activates the pump as needed to support hot water demand, and shuts the pump down only after evacuating the boiler's residual heat to the heating system or hot water storage tank. The Economaster II saves money in several ways. Electrical costs are reduced, since the pump is not running constantly. In addition, gas costs are cut, because residual heat that would otherwise escape through the flue is captured, and water is not subject to cooling during unnecessary circulation through the system. Finally, without constant water circulation, wear and tear on the boiler waterways is also reduced, prolonging the life of the boiler. And the Economaster II delivers these savings regardless of variable load conditions experienced by the boiler!
