Abstract: An additive heat transfer unit (AHTU) can be part of or added to an air source heat pump HVAC system. The heat pump system can include a compressor, an expansion valve, first and second air source heat exchangers, and a reversing valve. The system can have a cooling mode and a heating mode, such that in the cooling mode the first air source heat exchanger functions as an evaporator and the second air source heat exchanger functions as a condenser, this being reversed in the heating mode. The AHTU can include a liquid source heat exchanger that can be used to increase the efficiency of the system.

Abstract: A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, a second fuel hook-up for connecting the second fuel type to the heater assembly, and an internal valve. The actuation member can control the position of the internal valve based on whether the first or the second fuel hook-up is used.

Abstract: A heating assembly can include a gas hook-up and a pressure switch. The pressure switch can be in fluid communication with the gas hook-up and be movable at a predetermined threshold pressure from a first position to a second position. The pressure switch can be further configured such that if a fuel is connected to the gas hook-up that has a delivery pressure either above the predetermined threshold pressure in one situation or below the predetermined threshold pressure in another, the fuel will act on the pressure switch to move it from the first position to the second position.

Abstract: A heating apparatus can have a sealed combustion chamber, a burner, and various air channels to direct air into the sealed combustion chamber and to provide heated air to the desired area or environment such as an interior room. A channel can direct a flow of air along a face of the sealed combustion chamber to cool the face. The channel can be within or outside of the sealed combustion chamber. Alternatively, or in addition, the heating apparatus can be capable of operating as a direct vent device or as a vent free device.

Abstract: A dual fuel heating source can have a fuel selector valve for selecting between a first fuel and a second fuel different from the first. The dual fuel heating source may selectively have a regulator unit, and an outlet valve. The regulator unit can be configured to regulate the pressure of two different fuels. The outlet valve can be connected to the fuel selector valve such that selecting a fuel can determine the path fuel will flow through the outlet valve and also out of the heating source.

Abstract: A dual fuel heater can couple with one of two fuel sources operating at different pressures. The dual fuel heater can have a first fuel line, a second fuel line, a fluid flow controller, and a combustion chamber. The fluid flow controller can selectively permit flow of a first fuel to either the first fuel line or flow of a second fuel to the second fuel line. The first fuel line can be in communication with a first oxygen depletion sensor orifice and the second fuel line can be in communication with a second oxygen depletion sensor orifice.
