Electric water heater having dry fire protection capability

A water heater has a tank defining an interior volume, a heating element disposed within the interior volume, and a temperature sensor disposed with respect to the heating element so that the temperature sensor detects temperature of an area ambient to the heating element in the interior volume. The heating element is actuated at a predetermined actuation rate and for a cumulative actuation period so that the predetermined actuation rate maintains the heating element below a predetermined maximum temperature in air and so that the actuation period contributes a predetermined amount of energy to the ambient area when the heating element is immersed in water.. ...

Fuel-fired appliance with thermoelectric-powered secondary electric heating

A fuel-fired appliance with thermoelectric-powered secondary electric heating has a burner providing hot combustion gasses into a first housing. A second housing containing a fluid receives heat from the combustion gasses in the first housing. ... Rheem Manufacturing Company

Apparatus and methods for controlling an electronic expansion valve in a refrigerant circuit

A specially designed electronic expansion valve control system is provided for use with a refrigerant-based air conditioning circuit having a compressor, a condenser coil, an electronic expansion valve and an evaporator coil fluid coupled in series. The control system includes a unit control and an expansion valve control. ... Rheem Manufacturing Company

Apparatus and methods for heating water with refrigerant and phase change material

The metal tank portion of an electric water heater is protected against corrosion utilizing a corrosion protection system that detects a voltage potential between the sheath portion of a tank water-immersed electric heating element and the tank. In one embodiment of the corrosion protection system the sensed sheath/tank potential is utilized to enable a user of the water heater to accurately gauge the necessity of replacing a sacrificial anode extending into the tank. An apparatus for heating water has a tank for storing water and an air conditioning system that defines a refrigerant flow path through which refrigerant flows. The refrigerant flow path passes through a heat exchanger so that refrigerant heat is contributed to the tank. ... Rheem Manufacturing Company

Fuel/air mixture and combustion apparatus and associated methods for use in a fuel-fired heating apparatus

A fuel-fired furnace incorporates specially designed fuel/air mixing and combustion structures. The fuel/air mixing structure is of a mixing sound-attenuating design and comprises a venturi having a perforated sidewall portion and being surrounded by a noise-damping housing chamber communicating with the interior of the venturi via its sidewall perforations. ... Rheem Manufacturing Company

Gas fired modular blower control and associated methodology

An air heating and cooling system includes (1) a heat pump, illustratively devoid of auxiliary electric resistance type air heating structure, operative to provide refrigerant-based heating or cooling of air being delivered to a conditioned space, (2) a fuel-fired modular blower selectively operable to generate combustion heat, and (3) a control system associated with the heat pump and the modular blower. The control system has a heat pump thermostat electrically connected to a modular blower control and operative to transmit to the modular blower a first signal indicative of heating operation of the heat pump, and a second signal indicative of a need for alternative heat during a heating demand cycle. ... Rheem Manufacturing Company

Motor/damper assembly for fuel-fired water heater

A motor/damper assembly installable on the top end of a fuel-fired water heater includes a support plate structure upon which a flue collar with a pivotally supported flue damper, a drive motor, and a drive shaft interconnecting the motor damper are mounted. The assembly is installed by placing the collar over the upper end of the water heater flue, securing the support plate structure to the top end of the water heater, and positioning a top cover housing on the support plate structure. ... Rheem Manufacturing Company

Electric water heater having dry fire protection capability

A water heater has a tank with at least one heating element. A non-invasive liquid level sensor is disposed in communication with a water containing volume encompassing the tank volume. ... Rheem Manufacturing Company
