US 2026/0202096 A1 · Metering Valve System for a Water Heater

Abstract

A metering valve for a water heater system is provided. The metering valve is configured to selectively control the amount of water flowing into the water tank and/or cold-water bypass shunt through rotation of a rotor. The rotor is attached to the motor such that when the motor is driven, the rotor is rotated in either the clockwise or counterclockwise direction. The rotor is shaped such that, depending on the degree of rotation of the rotor, the size of the openings at the cold water inlet and the cold water bypass shunt (as well as the water inlet into the metering valve) are adjusted. That is, the ratio of water entering the tank and/or passing to the cold bypass shunt may be adjusted based on the degree of rotation of the rotor, which in turn controls the temperature of the water exiting the metering valve system at the outlet of the water tank

Dependent claims

A water heater comprising:

a water tank;
a metering valve comprising:
a rotor;
a motor connected to the rotor and configured to cause a rotation of the rotor;
a water inlet in fluid communication with a water source;
a first outlet in fluid communication with the water tank;
and
a second outlet in fluid communication with a bypass shunt;
and
a mixing tee in fluid communication with an outlet of the water tank and the bypass shunt, wherein at least one of the water inlet, the first outlet, or the second outlet is partially or fully obstructed by the rotor based on an angle of the rotor.
