Patent number: 11988466Abstract: 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.Type: GrantFiled: May 12, 2021Date of Patent: May 21, 2024Assignee: Rheem Manufacturing CompanyInventors: Amin Monfared, Juan Garcia, Juan Carlos Montanez, Satya Kiran Gullapalli, Alexander Chow
