Noritz EZ Pro vs 9.8 GPM Specs
Flow capacity
The Noritz EZ Series Pro delivers 11.1 GPM at 199,900 BTU. This higher output supports multiple simultaneous showers in larger homes. The other unit lists 9.8 GPM in its title but shows 7.5 GPM in its attributes. Even at its peak, it provides less volume than the EZ Pro. You get more hot water simultaneously with the EZ Series Pro. This matters if you have several bathrooms or high-demand appliances running at once. The EZ model handles larger household needs better due to its superior flow rate.
Power requirements
The Noritz EZ Series Pro requires 120 V power to operate its controls and ignition system. The other unit does not list a specific voltage in the provided data. Most tankless heaters need electricity, but the exact requirement varies by model. You must ensure your home has the correct outlet for the EZ Series Pro. Without this voltage, the unit will not function. The lack of voltage data for the other model makes a direct comparison difficult here. You should verify the electrical specs for the NR98SVNG before installation.
Physical footprint
Size matters for installation space. The Noritz EZ Series Pro measures 11.8 x 18.1 x 26.1 inches and weighs 77.2 pounds. The other unit is smaller, measuring 13.8 x 10.6 x 23.6 inches and weighing only 54 pounds. The NR98SVNG takes up less wall space and is lighter to handle. This makes it easier to fit in tight utility closets or small mechanical rooms. If you have limited space, the smaller unit is the practical choice. The EZ Pro is bulkier and heavier.
Heat exchanger build
The other unit features a heat exchanger made from commercial-grade copper. It uses piping that is 25% thicker than standard models. This suggests greater durability and resistance to corrosion over time. The Noritz EZ Series Pro data does not specify the material or thickness of its heat exchanger. Thicker copper piping can often handle higher temperatures and pressures. This is a known strength of the NR98SVNG. You get a potentially longer-lasting core component with the other model, assuming the EZ Pro uses standard materials.
Included accessories
The other unit comes with a remote thermostat and a 6-foot power cord. This allows you to control the water temperature from a distance. It also simplifies electrical connection. The Noritz EZ Series Pro data does not mention any included accessories. You may need to purchase a remote control separately if you want that feature. The included cord for the other unit adds convenience. You get more out-of-the-box functionality with the NR98SVNG. This can save you time and extra purchases during setup.
Modular capability
The other unit can be linked with a second unit using the QC-2 Quick Connect Cord. This allows you to increase total flow capacity by doubling the system. The Noritz EZ Series Pro data does not mention this linking capability. If you need even more hot water later, you can expand the other system easily. The EZ Pro stands alone without this specific expansion option listed. You gain flexibility for future upgrades with the NR98SVNG. This is useful for growing households.
Which Noritz Tankless Heater Fits You
Large home needing high flow
You need the Noritz EZ Series Pro for its 11.1 GPM flow rate. This unit delivers 199,900 BTU to support multiple simultaneous showers. Its 120-volt operation and compact 11.8 by 18.1 by 26.1-inch footprint make it suitable for indoor or outdoor installation. Choose this model if your household requires maximum hot water capacity.
Budget conscious small household
Select the Noritz NR98SVNG if you prefer a lighter, smaller unit. It weighs only 54 pounds and measures 10.6 by 23.6 by 13.8 inches. The commercial-grade copper heat exchanger features 25% thicker piping for durability. It includes a remote thermostat and a 6-foot power cord, offering flexibility for your installation needs.
User wanting remote control
The Noritz NR98SVNG comes with a remote thermostat and a 6-foot power cord included in the box. This feature allows you to adjust settings from a distance without accessing the unit directly. The other model does not list this accessory. If you value convenient temperature adjustment, this included hardware is a practical advantage.
