A combined heat, cooling and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.

A flue baffle for a water heater comprises a plurality of holes along a length of the baffle and a plurality of bent blades along the length of the baffle, where each hole of the plurality of holes is adjacent to a bent blade of the plurality of bent blades. The holes are configured to permit flue gas to pass through the holes. The bent blades can have an alternating pattern where a first bent blade extends from one side of the baffle and the next bent blade extends from an opposite side of the baffle. A press tool for forming the baffle comprises a piercing tool for forming the plurality of holes and a lance and fold die for forming the bent blades.

An assembly for a water heater having a burner includes a tube extending longitudinally along a centerline from a first end adjacent the burner to a second end. The first end includes a flared portion extending away from the centerline. A partition is provided downstream of the burner and includes an opening having a curved flange defining an opening for receiving the flared portion of the tube.

The present disclosure discloses a water heater, and a scale detection system and method. The scale detection system comprises: a first temperature detector configured to acquire a first temperature of a heat exchange zone of a water heating device; a second temperature detector configured to acquire a second temperature indicating a water temperature in the water heating device; and a controller in communication with the first temperature detector and the second temperature detector, and configured to acquire a temperature difference between the first temperature and the second temperature based on the first temperature acquired by the first temperature detector and the second temperature acquired by the second temperature detector, and determine that a scale generation amount in the water heating device reaches a preset threshold when at least one of the following judgment conditions is met: the first temperature is not less than a preset temperature threshold; and the temperature difference is not less than a preset temperature difference threshold. The present disclosure can ensure that a user can be reliably and timely reminded to clean the scale under different working conditions.

A gas fueled water heater appliance may include a tank for storage of water, a chamber wall, a gas burner, a gas conduit, a support post, and a guide bracket. The chamber wall may define a combustion chamber and a conduit hole. The gas burner may be positioned adjacent to the tank and within the combustion chamber. The gas conduit may extend from the gas burner and through the conduit hole. The support post may be fixed to the gas burner within the combustion chamber. The guide bracket may be mounted within the combustion chamber and define a mounting point. The guide bracket may be in selective engagement with the support post at the mounting point. The guide bracket may include a pair of lateral arms extending outward from the mounting point toward the chamber wall to guide the support post to the mounting point.

A heat exchanger having a circulation guide, the heat exchanger comprising: a heat exchanger body; an inlet port, which is connected to a bottom end of the heat exchanger body; a discharge port which is connected to a top end of the heat exchanger body; a top body tube installed at a top end of an inside of the heat exchanger body; a bottom end plate installed at a bottom end of the inside of the heat exchanger body; and combustion pipes, which each have a top end connected to pass through a floor surface of the top body tube.

A water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively ran only the pilot for at least pan of a heating cycle to increase the recharge lime of the rechargeable power storage device while still healing the water in the water heater.

A draft inducer blower assembly for use with a water heater has a housing, a motor, and a fan. The housing has an exhaust volute surrounding the fan and a base adapted to be mounted atop a water heater. The base has an inlet port adapted to receive exhaust gas from the water heater. The fan is connected to the motor for rotation about a rotation axis. The exhaust volute and the base are non-adjustably fixed relative to each other. The exhaust volute has a cut-off at a cut-off angle relative to the rotation axis. The exhaust volute has an exhaust outlet passageway that extends to an exhaust port. The exhaust port is lower than the top of the exhaust volute.

A system and a method is described for remotely controlling gas consumption by a power vented gas-fired water heater to reduce consumption of gas by a consumer connected to a gas distribution bank network of a gas provider during overload periods where gas demand is at a peak. The system comprises a consumer controller in communication with the gas provider whereby the controller can operate a modulating gas control valve either directly or through the control of the fan speed of a power vented blower to reduce the supply of gas to the burner of the gas-fired water heater when asked by the provider to do so. Temperature sensors are associated with the water holding tank of the gas-fired water heater to feed water temperature signals to a computer of the controller whereby to enable the controller to execute informed corrective action for the reduction in gas consumption by regulating the gas control valve to reduce the supply of gas to the burner of the water heater.
