Noritz NR98SVNG vs NR98-OD NG Comparison
flow rate capability
Both models are rated for 7.5 GPM at the faucet, which handles most household demands. However, the NR98SVNG features a higher peak capacity of up to 9.8 GPM according to its features list. This extra headroom means the SVNG can maintain stronger pressure when multiple showers run simultaneously. The NR98-OD NG sticks to its 7.5 GPM limit. If your home has high simultaneous usage, the SVNG’s higher potential flow rate provides a practical advantage. You get more flexibility with the SVNG, while the NR98-OD offers consistent performance within its lower maximum.
installation location
The NR98-OD NG is designed for outdoor installation only. It requires no venting and is built to withstand weather. In contrast, the NR98SVNG supports both indoor and outdoor use. This dual capability makes the SVNG much more versatile for different home layouts. You can place it in a garage, basement, or utility closet if needed. The NR98-OD lacks this flexibility. If you need to install the unit inside a structure, the SVNG is the only choice. For outdoor-only setups, both work, but the SVNG gives you more options for placement.
build quality
The NR98SVNG uses a heat exchanger made from commercial-grade copper with piping that is 25% thicker than standard models. This construction suggests greater durability and resistance to wear over time. The NR98-OD NG description does not specify its heat exchanger material or pipe thickness. While both use natural gas, the SVNG’s explicit mention of thicker commercial-grade copper gives it an edge in perceived build quality. You get a more robust internal component with the SVNG. The NR98-OD relies on standard specifications without highlighting enhanced materials. For long-term reliability, the SVNG’s thicker piping is a clear benefit.
control features
The NR98SVNG includes a remote thermostat and a 6-foot power cord in the box. This allows you to adjust water temperature from a distance, which is useful for indoor installations. The NR98-OD NG features a self-diagnostic onboard computer system but does not list a remote thermostat. While the diagnostic system helps with troubleshooting, the remote control adds convenience for everyday adjustments. If you value easy temperature tweaking without accessing the unit directly, the SVNG is better. The NR98-OD requires you to interact with the main unit for settings. The included remote gives the SVNG a practical advantage.
venting requirements
The NR98-OD NG requires no venting, which simplifies installation and reduces material costs. This is a key feature for outdoor units. The NR98SVNG supports indoor installation, which typically requires venting for safety. The data does not explicitly state venting requirements for the SVNG in outdoor mode, but indoor use implies it. If you want a zero-venting solution, the NR98-OD is the clear choice. The SVNG may require venting depending on your final location. For simplicity and ease of setup without ductwork, the NR98-OD NG has a distinct advantage. You avoid complex venting systems with the NR98-OD.
system diagnostics
The NR98-OD NG includes a self-diagnostic onboard computer system to help monitor performance and detect issues. The NR98SVNG features do not explicitly mention a self-diagnostic system, though it includes a remote thermostat. While the SVNG offers remote control, the NR98-OD provides built-in diagnostics for maintenance. This feature helps you identify problems without external tools. If you prefer automated error checking, the NR98-OD is superior. The SVNG relies on its remote for adjustments but lacks stated diagnostic features. For easier troubleshooting and system monitoring, the NR98-OD NG offers a helpful technical advantage.
Which Noritz model suits your home
Outdoor installers needing simple setup
The NR98-OD NG is designed for outdoor installation only, so you do not need to plan for venting. It delivers 7.5 GPM of hot water using natural gas. The unit features a self-diagnostic onboard computer system to help you monitor performance. Its 84% thermal efficiency means you get reliable heat output without complex ductwork requirements.
Users wanting higher peak flow rates
The NR98SVNG offers flow rates up to 9.8 GPM, which exceeds the standard 7.5 GPM rating of the other model. This extra capacity helps when multiple showers run at once. It includes a remote thermostat and a 6-foot power cord for easier placement. You can also link two units with the QC-2 Quick Connect Cord for even greater output.
Installers needing indoor or outdoor flexibility
The NR98SVNG supports both indoor and outdoor installation locations. This gives you more options for where to place the unit in your home.
