Some larger boilers have a 2, or 3-stage burner, but this is usually controlled by pressure from a Vaporstat. On a call for heat, the burner is on full fire, and when the pressure rises to maybe 4 ounces, the Vaporstat will either make or break a circuit, causing the burner to go to low fire to maintain that pressure, and not exceed it.

Below a firing rate of 50%, these so called "step-modulation" burners actually operate in an on/off mode. Their inability to operate efficiently at the minimum or mid-fire input rate decreases the boiler's operating efficiency. Steam loads rarely operate at the "on/off" or "low/high/low" firing rates of the modular units, so
