ABSTRACT:
A dual-rate fuel flow control system for the gaseous or liquid fuel supplied to the burner of a space heater, comprising a valve controllable to supply full fuel flow to the burner at the start of a heating cycle to deliver full heat to the heat exchanger chamber in which circulates the heat transfer fluid, and controllable to supply reduced fuel flow to the burner simultaneously with starting the circulating of the heat transfer fluid from the heat exchanger to the space to be heated.
