Abstract
A water heater including a tank configured to hold a fluid, a burner configured to manipulate a temperature of the fluid within the tank, one or more sensors configured to sense one or more characteristics of the burner, a fuel injector position upstream of the burner, and a controller. The controller includes an electronic processor and a memory. The controller is configured to receive one or more signal from the one or more sensors corresponding to the one or more characteristics, and control the fuel injector based on the one or more signals.
Claims20
A water heater comprising:
- a tank configured to hold a fluid;
- a burner configured to manipulate a temperature of the fluid within the tank;
- one or more sensors configured to sense one or more characteristics of the burner;
- a fuel injector positioned upstream of the burner;
- and
- a controller having an electronic processor and a memory, the controller configured to
- receive one or more signals from the one or more sensors corresponding to the one or more characteristics, and
- control the fuel injector based on the one or more signals.
A method of operating a water heater, the method comprising:
- manipulating, via a burner, a temperature of a fluid;
- sensing, via a sensor, a characteristics of the burner;
- injecting, via a fuel injector, a fuel upstream the burner;
- supplying, via a blower, an air/fuel mixture to the burner;
- and
- controlling, via a controller, the fuel injector based on the characteristic.
A gas-fired appliance comprising:
- a burner configured to manipulate a temperature of the fluid within the tank;
- a fuel injector configured to inject fuel upstream of the combustion chamber;
- a blower configured to provide an air/fuel mixture to the burner;
- a sensor configured to sense a characteristic of the burner;
- and
- a controller having an electronic processor and a memory, the controller configured to receive a signal from the sensor corresponding to characteristic of the burner, and control the fuel injector and the blower based on the signal.
