Benefits of technology

The present invention is about a water heater appliance that includes a sealed system and an electric heating element for heating water within a tank. The electric heating element is positioned below a temperature sensor mounted to the tank, which helps to improve the heating efficiency. The appliance also includes a dip tube that extends into the tank to measure the temperature. In addition, the invention includes a heat pump water heater appliance that includes a tank with a sealed system and an electric heating element positioned inside the tank, as well as a temperature sensor mounted on the tank. These features make the water heater appliance more efficient, cost-effective, and user-friendly.

Problems solved by technology

However, accurately determining the volume of water added to the tank with the single temperature in such a configuration can be difficult.

Abstract

A water heater appliance includes a sealed system and an electric heating element. The sealed system and electric heating element are configured for heating water within an interior volume of a tank. A temperature sensor is mounted to the tank. The electric heating element is positioned below the temperature sensor within the interior volume of the tank.

Description

FIELD OF THE INVENTION[0001]The present subject matter relates generally to water heater appliances, such as heat pump water heater appliances.BACKGROUND OF THE INVENTION[0002]Certain water heater appliances include a tank therein. Heating elements, such as sealed systems, gas burners, electric resistance elements, or induction elements, heat water within the tank during operation of such water heater appliances. In particular, the heating elements generally heat water within the tank to a predetermined temperature. The predetermined temperature is generally selected such that heated water within the tank is suitable for showering, washing hands, etc.[0003]During operation, relatively cool water flows into the tank, and the heating elements operate to heat such water to the predetermined temperature. Temperature sensors are typically included in water heater appliances to, among other things, determine the temperature of the water in the tank. Many water heater appliances utilize mu...
