Noritz EZ vs NRC98 Pro Specs
Fuel type
You need to match the heater to your home’s energy source. The Noritz EZ Series Pro uses natural gas, which is delivered via underground pipelines. This model, the GQ-C3261WX-FF, is designed for that specific fuel line. In contrast, the Noritz NRC98-DV-LP runs on liquid propane. Propane is stored in tanks, making it a common choice for rural areas without gas lines. Using the wrong fuel type will prevent the unit from operating. You must ensure your supply matches the unit’s design before purchasing.
Flow rate
Flow rate determines how many fixtures can run at once. The Noritz EZ Series Pro delivers 11.1 gallons per minute. This higher capacity supports multiple showers and appliances simultaneously. The Noritz NRC98-DV-LP provides 9.8 gallons per minute. While still robust, this lower rate may limit concurrent usage in larger households. If you have a large home with high demand, the EZ Series Pro offers more volume. The difference is over one gallon per minute, which adds up during peak usage times.
BTU output
BTU rating indicates heating power. The EZ Series Pro generates 199,900 BTU. This higher output helps maintain temperature when flow rates are high. The NRC98-DV-LP produces 180,000 BTU. It is slightly less powerful in terms of raw heat generation. Both units use 120-volt power for controls, but the heating element differs. The EZ Series Pro’s higher BTU allows it to handle colder incoming water more effectively. This makes it a stronger choice for areas with very cold groundwater.
Dimensions
Space constraints often dictate which unit fits your installation spot. The EZ Series Pro measures 18.1 inches wide, 26.1 inches high, and 11.8 inches deep. It is a wider, taller unit. The NRC98-DV-LP is much narrower at 8 inches wide, but stands 9 inches high and 24 inches long. The NRC98 is more compact in width, which helps in tight cabinets. However, it is longer. You need to measure your intended location carefully to ensure either unit fits without obstruction.
Installation location
Where you place the heater affects ventilation and accessibility. The EZ Series Pro is rated for both indoor and outdoor use. This flexibility allows you to mount it on an exterior wall or in a garage. The NRC98-DV-LP is listed as a residential unit, but specific indoor/outdoor ratings are not detailed in the provided specs. Generally, propane units require careful ventilation. If you need a unit explicitly rated for outdoor exposure, the EZ Series Pro provides that clear designation in its features.
Weight
Weight matters for mounting and structural support. The EZ Series Pro weighs 77.2 pounds. It is heavier due to its larger internal components and higher capacity. The NRC98-DV-LP weighs 65 pounds. It is lighter, which may simplify installation on standard wall brackets. Both units are solid, but the difference is over 12 pounds. If you are installing on a weak wall, the lighter NRC98 might be easier to support. Always use appropriate anchors for either model.
Which Noritz model fits your needs?
High-demand households needing max flow
You need consistent hot water for multiple simultaneous uses. The Noritz EZ Series Pro delivers 11.1 GPM, which is higher than the competitor. This higher flow rate supports larger homes or busy bathrooms. You also get 199,900 BTU of heating power. This ensures water stays hot even during peak usage times.
Users with existing propane lines
Your home already has a propane tank or supply line. This unit runs on liquid propane, matching your current fuel source. It provides 9.8 GPM and 180,000 BTU. This capacity is sufficient for standard residential needs. You avoid the cost and complexity of installing a new natural gas pipeline.
Those prioritizing compact installation size
You have limited space for the water heater. The NRC98-DV-LP is narrower at 8 inches wide compared to the 18.1-inch EZ Series. It also weighs less at 65 pounds. This lighter, slimmer profile makes it easier to mount in tight closets or small utility areas. You save space without sacrificing core heating performance.
