The Raypak Economaster II is a solid-state time-
delay relay which regulates pump operation to
optimize system  efficiency and reduce operating
costs. 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 es-
cape through the flue is captured, and water is not
subject to cooling during unnecessary circulation
through the system. Finally, without constant wa-
ter circulation, wear and tear on the boiler water-
ways 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!
