    摘要: A water heating system includes a burner and a gas valve fluidly connected to the burner to deliver a flow of combustible gas thereto. The gas valve has an adjustable throttle for the flow of combustible gas, along with a motor to adjust a position of the throttle. A controller is configured to determine a throttle position corresponding to a target air-fuel ratio of the burner during a calibration sequence, and to control the motor in order to operate the burner at that target air-fuel ratio throttle position during a start sequence. The controller is configured to monitor a characteristic of the burner during the start sequence, and to initiate the calibration sequence if the monitored characteristic exceeds an error threshold.

    摘要: A hot water pressure washer for delivering a high pressure stream of heated water. The hot water pressure washer includes an engine, a source of gas, a water heater, and a high pressure water pump. In one embodiment, the gas is one of liquefied natural gas, liquefied petroleum gas, gasoline, or propane. The water heater includes a gas input adapted to be coupled to an outlet of the source of gas and a water input adapted to be coupled to a source of water. The water heater includes a water heater inlet, adapted to receive gas from the source of gas, and a water heater outlet, adapted to provide a heated water to a spray wand. A high pressure water pump receives water from the water heater outlet and the water pump outlet provides the pressurized heated water to a spray wand.
