Rite Boilers can provide automatic stack dampers for all our atmospheric fired boilers. In addition to keeping the heat inside the boiler as the burner cycles on and off during normal operation, they'll also stop winter air from coming down the stack and freezing the water in the boiler tubes (potentially bursting them) whenever the boiler is not in operation.
