Power Noritz NR98ODLP 9.8 GPM 199,900 BTU Outdoor LP Tankless Water Heater

Replace bulky tanks with continuous hot water outside the home. The Noritz NR98ODLP mounts outdoors—so there’s no venting to run—and delivers up to 9.8 GPM for busy households. A wide firing range (16,000–199,900 BTU/h) modulates to actual demand, helping stabilize temperatures and reduce fuel use. The compact, weather-ready cabinet includes freeze protection and ships with a wall remote for simple setpoint control. It’s a proven, non-condensing workhorse sized right for whole-home LP service.

Save Fuel With Smart Modulation

A wide 16k–199.9k BTU/h firing range (≈12.5:1 turndown) means the NR98ODLP heats only what you use, supporting a UEF around 0.81 for this non-condensing platform. Fewer temperature swings and less short-cycling translate to comfort and potential fuel savings.

Everyday Performance You Can Feel

Flow stays practical across real temperature rises: about 9.8 GPM @ 30 °F, 5.6 GPM @ 60 °F, and 3.4 GPM @ 100 °F (see chart). That supports multiple fixtures in typical homes—showers, laundry, and the dishwasher—without waiting on a tank to recover.

Durable Build, Easier Care

Noritz uses commercial-grade copper with thicker-wall tubing in the heat exchanger for long service life. The included remote lets you set and lock temperatures, and Noritz recommends isolation valves for straightforward annual descaling to keep performance on spec.

Installer-Friendly Outdoor Design

This model is outdoor-only, so there’s no vent system to design—just mount, plumb 3/4″ lines, connect 120 VAC, and gas. Quick-Connect capability allows two units to be linked for added capacity, and front access simplifies service clearances.

Sized Right For Exterior Walls

At 23.6″ × 13.8″ × 9.4″, the slim cabinet tucks onto siding, stucco, or a recess box without dominating the elevation. Built-in freeze protection (outdoor to about −4 °F) supports four-season installs—verify clearances and local code placement.

Controls & High-Altitude Readiness

The wall remote sets 100–140 °F in 5 °F steps, with a default of 120 °F. A high-elevation DIP-switch adjustment (≥2,000 ft) helps maintain combustion at altitude—follow the installation manual for the proper setting in your region.

LP Confidence, Code Compliance

The NR98 series is listed to ANSI Z21.10.3 / CSA 4.3, with UPC/NSF listings and Low-NOx compliance. Outdoor placement eliminates vent penetrations while meeting safety and emissions requirements when installed per code.
