Specs: Westinghouse vs GE Heaters
Use and capacity
The Westinghouse unit is a whole-house tankless heater, providing continuous hot water for multiple fixtures like showers and sinks simultaneously. It has no storage tank. The GE model is a 6-gallon mini tank designed for under-sink use. It serves single points of use, such as a kitchen or bathroom sink. The Westinghouse supports whole-house needs, while the GE is a point-of-use booster or standalone unit for limited spaces. This difference defines their primary application in your home.
Flow rate
The Westinghouse heater delivers up to 5.55 GPM of hot water with a starting flow rate of 0.79 GPM. This high flow supports simultaneous use. The GE unit is a small tank with no published GPM flow rate in the data. Tankless units generally provide endless hot water, while small tanks rely on stored volume. The Westinghouse offers significantly higher capacity for active water usage, making it suitable for higher demand scenarios compared to the GE's limited storage.
Voltage and power
The Westinghouse heater requires 240V power and 24 kW of wattage, needing a 100A breaker setup. The GE unit operates on 120V power, which is standard for many household outlets. The GE is easier to install electrically if you have standard 120V circuits available. The Westinghouse demands a dedicated high-amperage electrical setup. The GE wins on electrical accessibility for standard homes without major upgrades.
Dimensions and weight
The Westinghouse heater measures 17.1 inches high, 13 inches wide, and 4.3 inches deep, weighing 17 pounds. It mounts flush against a wall. The GE unit is a cube shape, measuring 17.8 inches high, 17.3 inches wide, and 17.3 inches deep, also weighing 17 pounds. The Westinghouse is much thinner, saving space in narrow installations. The GE is bulkier but fits under sinks. The Westinghouse has a slimmer profile.
Smart features
The Westinghouse heater includes smart Wi-Fi connectivity, allowing remote temperature adjustment and usage monitoring via an app or voice commands with Alexa and Google Home. The GE unit features an intuitive mechanical thermostat with a turn-of-knob control. It lacks smart connectivity. The Westinghouse offers modern remote management capabilities. The GE relies on manual adjustment. The Westinghouse is better for smart home integration.
