Ge Appliances ge40s10bmm Smart Electric Water Heater 40 Gal

Product Description

The GE Appliances ge40s10bmm is a smart electric water heater rated at 40 gallons unit capacity, designed for residential hot water supply systems. The flexible capacity feature allows effective output to reach 64 gallons at the X-High setting, extending usable hot water beyond the nominal tank size without requiring a larger unit. Licensed plumbers and HVAC technicians typically handle installation, as the unit connects to a standard 240-volt residential circuit and a dedicated cold water supply line. The gray cabinet finish is suited for utility rooms, garages, and mechanical closets.

The ge40s10bmm is intended for residential applications where a standard 40-gallon electric tank water heater is the specified solution. The smart functionality and flexible capacity settings allow the installer or homeowner to adjust output based on household demand, making it well-suited for small to medium households or retrofit situations where the existing footprint is fixed. It is designed as a direct replacement or new installation in homes that have an existing 240-volt electric water heater circuit already in place.

Key Features

• 40-gallon unit capacity with effective output up to 64 gallons at X-High setting
• Flexible Capacity technology adjusts hot water output to match demand without upsizing the tank
• Smart-enabled controls allow remote monitoring and setting adjustments
• Gray exterior finish suits standard utility and mechanical room installations

Compatibility

Designed as an OEM-style residential electric water heater replacement or new installation for homes with an existing 240-volt electric water heater circuit and standard plumbing connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and the manufacturer instructions. Shut off the electrical circuit breaker and the cold water supply valve before beginning any work on the unit. The unit requires a dedicated 240-volt circuit sized to the nameplate amperage — confirm wire gauge and breaker rating before connecting. Pressure-relief valve installation and discharge line routing must comply with the applicable plumbing code for the jurisdiction.
