Provided is an RPM control method for an inducer for a gas furnace that induces a flow of combustion gas produced in a burner from a heat exchanger to an exhaust pipe. The RPM control method for an inducer for a gas furnace includes: (a) initiating a heating operation for the gas furnace; (b) determining whether the operation time during which the heating operation is performed is equal to or longer than a first time period; (c) if it is determined that the operation time is equal to or longer than the first time period, detecting whether a pressure switch is turned OFF; and (d) if the pressure switch is detected as turned OFF, increasing the RPM of the inducer by a first value.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A fluid discharge event detection apparatus measures a change in capacitance to detect the presence of a fluid in a sensing conduit where the presence of fluid indicates a discharge event. The apparatus includes a first conduit, the sensing conduit and a control valve, coupled between the first conduit and the sensing conduit. The control valve is configured to activate and fluidly couple the first conduit and the sensing conduit to one another when the control valve detects at least one predetermined condition of a fluid within the first conduit. A sensor, configured to measure a capacitance value, is disposed about the sensing conduit. A controller, coupled to the sensor, is configured to detect a change in the sensing conduit capacitance value and assert an alarm condition upon detection of the change in the sensing conduit capacitance value.

A burner appliance is disclosed. The burner appliance includes a byproduct sensor in an exhaust flue and/or a barometric pressure sensor to detect an environmental pressure at the burner appliance. By calculating concentrations of combustion byproducts in the exhaust with the byproduct sensor, a controller can adjust blower speed and/or fuel rate to modify combustion efficiency. By calculating the environmental pressure at the burner with the barometric pressure sensor, the controller can adjust blower speed and/or fuel rate to modify combustion efficiency. The barometric-pressure data can also be used to adjust blower speed control bands, thereby calibrating the control bands based on environmental pressure. The environmental pressure can be indicative of altitude and/or weather conditions. Methods of operating said burner appliance are also disclosed.

The flameless heater system includes an energy source comprising a diesel engine configured to create volumes of air, a hydraulic system to control engine loading for heat generation and for air moving, and a control system, operatively coupled with the energy source and the hydraulic system to control at least one of a speed of the diesel engine, a loading of the diesel engine, or a fan speed.

A water heater can include a heat source and a heat exchanger that transfers heat to the water. A header attached to the heat exchanger provides an inlet and an outlet for water to flow into and out of the heat exchanger. The header can also include an anode assembly that releasably attaches to the header. The anode assembly can be located at a bottom of the header so that an anode in the anode assembly remains in contact with the water when water is flowing through the heat exchanger.

A heat pump assembly (100) arranged to be connected to a thermal energy circuit (300) comprising a hot conduit (302) configured to allow thermal fluid of a first temperature to flow therethrough, and a cold conduit (304) configured to allow thermal fluid of a second temperature to flow therethrough, the second temperature is lower than the first temperature, and a cooling machine assembly (200) arranged to be connected to a thermal energy circuit (300) comprising a hot conduit (302) configured to allow thermal fluid of a first temperature to flow therethrough, and a cold conduit (304) configured to allow thermal fluid of a second temperature to flow therethrough.

A flame sensor for a furnace of a heating, ventilation, and air conditioning (HVAC) system includes a sensor body and an electrically conductive member of the sensor body. The electrically conductive member is configured to be disposed within a flame region of a burner of the furnace and configured to receive electrical current from a controller of the furnace. The flame sensor also includes an anti-oxidation coating disposed on an outer surface of the electrically conductive member and configured to transmit the electrical current from the electrically conductive member. The anti-oxidation coating is configured to contact a flame produced by the burner and expose the electrical current to the flame.
