AI Technical Summary
Technical Problem
Conventional water heaters often require significant electrical upgrades and have limitations in operating during power outages or with limited grid power, especially when instantaneous hot water demand exceeds the capacity of heat pumps.
Method used
A battery-integrated water heater system that includes a heat pump and resistive elements, powered by an integrated battery, allowing operation on a smaller branch circuit and providing backup power during outages.
Benefits of technology
Enables continuous hot water supply even during power outages, reduces the need for electrical upgrades, and optimizes energy usage by leveraging battery storage and heat pump efficiency.

Abstract
A method of determining an operating configuration of a water heater that includes: a power cord connected to a receptacle; a housing; a battery disposed within the housing, and a water tank configured to hold a volume of water and having one or more heating elements. The method includes obtaining power availability data; and determining an operating configuration including one of: a full power configuration where the water tank operates at a maximum power greater than 120V input voltage based on power from both the receptacle and the battery or power solely from the battery, and a reduced power configuration where the water tank operates at a reduced power less than the maximum power, based on power solely from the receptacle or power solely from the battery.
