The disclosed technology can include a bypass valve assembly having a partition that can fluidly separate an inlet and an outlet of a fluid heating system. A first bypass valve and a second bypass valve can be mounted to the partition and configured to permit a fluid to flow between the inlet and the outlet. The first bypass valve and the second bypass valve can be configured to transition between a closed state and an open state. The first bypass valve and the second bypass valves can each have a spring configured to transition the respective first and second bypass valve from the closed state in response to experiencing a pressure that is greater than or equal to a respective first or second predetermined pressure. The second predetermined pressure can be greater than the first predetermined pressure.

Water heater bypass valves and devices thereto

Vent for water heating device

The disclosed technology includes a gas delivery system for controlling a target gas input rate of a fluid heating device. The system can include a sensor configured to measure a temperature of a gas flowing in a gas flow path, a modulating orifice in fluid communication with the gas flow path, and a motor in mechanical communication with the modulating orifice. The system can further include a controller configured to receive temperature data indicative of the temperature of the gas. The controller can determine a target cross-sectional area of the modulating orifice based at least in part on the target gas input rate and the temperature of the gas and, in response, output a signal to the motor to transition the modulating orifice from a first position to a second position having the target cross-sectional area.

Modulating gas orifice

Disclosed herein are fluid chemistry systems comprising fluid chemistry manifolds. The fluid chemistry manifolds can comprise an inlet, two flow paths in fluid communication with the inlet, one or more probe apertures, and an outlet in fluid communication with the two flow paths. The one or more probe apertures can be configured to receive at least a portion of a corresponding fluid chemistry probe. The probe can be configured to detachably attach to the one or more probe apertures and fluidly communicate with the flow path. The probe can include one or more of a pH sensor, an oxidation reduction potential (ORP) sensor, and a total dissolved solids (TDS) sensor. The systems can also comprise an adjustable valve configured to selectively permit a predetermined amount of fluid flow through the at least one of the two flow paths.

Fluid chemistry manifolds and systems

System and methods for controlling operating state of a heat transfer system are disclosed herein. The heat transfer system can include temperature sensor positioned at the fluid inlet line and the fluid outlet line and a heat exchanger between the fluid inlet line and the fluid outlet line. The heat transfer system can include a processor communicatively coupled to the first temperature sensor and the second temperature sensor. The processor can determine an inlet temperature of water flowing in the fluid inlet line and outlet temperature of water flowing in the fluid outlet line and can determine a delta temperature based on difference between the inlet temperature and the outlet temperature. Based on the inlet temperature and the delta temperature, the processor can determine an operating state of the heat transfer system.

System and method of controlling a heat transfer system

The disclosed technology includes a water heater system having a blower, an igniter, a burner, a heat exchanger, and a refractory configured to attach to the burner and the heat exchanger. The refractory can include a unitary ceramic housing having a top and a plurality of sidewalls and be configured to retain heat from combustion gases. The top can have a burner aperture configured to receive at least a portion of the burner and the plurality of sidewalls can form a cavity configured to receive at least a portion of the heat exchanger. One or more of the sidewalls can additionally have a protrusion extending laterally along an inside surface of the sidewall that is configured to contact the heat exchanger to form a seal between the heat exchanger and the refractory. A sealing material can substantially create a seal between the refractory and the heat exchanger.

Single-piece refractory for a water heating assembly

A water heater can include a baffle and a slab heat exchanger with at least two rows of heat exchanger tubes, each row comprising a plurality of heat exchanger tubes. At least one of the heat exchanger tubes comprises a tube and a plurality of fins on the exterior of the tube circumscribing the tube, wherein the outer edge of each fin of the plurality of fins is bent at least at the same three areas of each fin such that the bends form at least three flat or concave areas running along the length of the heat exchanger tube.

Heat exchanger tubes and tube assembly configurations

Systems and methods for monitoring anodic protection are disclosed. The system can include a sacrificial anode having an anode body, at least one cavity within the anode body, a conductor disposed within the at least one cavity, and electronic circuitry in communication with the conductor. The sacrificial anode can be electrically connected to a component or structure that is subject to galvanic corrosion. The cavity can be positioned such that as the anode degrades to a certain point, the conductor will contact water. In response, an alert can be provided to inform a user that the sacrificial anode needs replacement. The alert can be provided by activating a light, siren, or other device. The alert can also be sent to a mobile device or website.
