Westinghouse vs NOVIEEX Spec Comparison
Fuel type
The Westinghouse unit is an electric model that requires a 240V power supply. It uses a 24kW heating element to generate hot water without any combustion process. In contrast, the NOVIEEX model burns natural gas. It relies on a gas inlet and a burner system to heat water. This fundamental difference determines your installation options. You need an electrical panel upgrade for the Westinghouse. You need a gas line and proper venting for the NOVIEEX. Your existing home infrastructure will likely dictate which fuel source is feasible for your project.
Flow rate
Water flow capacity is critical for simultaneous use. The Westinghouse electric heater delivers up to 5.55 gallons per minute (GPM). This higher flow rate allows you to run a shower and a sink at the same time with minimal pressure drop. The NOVIEEX gas model provides up to 4.3 GPM. While sufficient for many households, it is lower than the Westinghouse output. If you have multiple bathrooms or high-demand fixtures, the Westinghouse offers more volume. The NOVIEEX is still capable of handling a shower and kitchen faucet together.
Temperature control
Precision matters for comfort. The NOVIEEX unit features a digital thermostat with a wide adjustable range from 95°F to 149°F. It offers ±1°F temperature control, ensuring consistent water heat for every use. The Westinghouse specifications do not list a specific temperature range or digital control precision in the provided data. It focuses on voltage and amperage requirements instead. For buyers who want exact temperature settings and precise digital feedback, the NOVIEEX provides clearer control parameters. The Westinghouse relies on smart app integration for monitoring rather than detailed thermal specs.
Dimensions
Space is often limited in utility rooms or closets. The Westinghouse unit is compact, measuring 17.1 inches in height, 13 inches in width, and 4.3 inches in depth. It weighs 17 pounds and mounts flush against the wall. The NOVIEEX model is larger, with dimensions of 28.5 inches in height, 17.3 inches in width, and 10.8 inches in depth. It weighs 19.8 pounds. The Westinghouse takes up significantly less vertical and horizontal space. If you have a tight installation spot, the Westinghouse design is more space-efficient.
Smart features
Modern homes often benefit from connected devices. The Westinghouse model includes built-in Wi-Fi connectivity. You can adjust the temperature and monitor usage via a mobile app or voice commands through Alexa and Google Home. The NOVIEEX specifications do not mention Wi-Fi or smart app integration. It features an LED touchscreen interface for local operation. If remote control and voice assistant compatibility are priorities for you, the Westinghouse offers superior smart home integration. The NOVIEEX requires manual adjustment at the unit.
Installation requirements
Professional installation is required for both units. The Westinghouse needs a 100A electrical system with three 40-amp double-pole breakers and 8 AWG wire. It uses 3/4-inch NPT water connections. The NOVIEEX requires a natural gas line with 1/2-inch NPT fittings and a 110V-120V AC power supply for its electronics. It also needs an exhaust pipe for venting. The electrical demands of the Westinghouse are substantial. The gas requirements of the NOVIEEX involve combustion safety and venting. Your existing utility connections will determine the ease of installation for each brand.
