Highlights

Noritz NR50 overview

This small Noritz tankless water heater is recommended for the apartments, condominiums, cottages, townhouses and where the inner space size is an issue. Since the Noritz NR50-OD is installed outside, no venting is required, and thanks to its quality materials it is protected and safe in different weather conditions.

Features

Water flow

Noritz NR50 water heater, with the maximum water flow of 5.0 gallons per minute provides sufficient hot water for one to two showers or applications, based on the temperature of the water supply. It will provide more hot water in southern parts of US than in colder, northern states.

Modulation for comfort

Due to its small size, Noritz water heater NR50 is equipped with the high performing single-flame burner, which is using direct ignition for lighting the gas. Full modulation gives its users much more comfort, as the water heater adjusts its power based on the water flow. It can work from its minimum 19,000 Btu/hr to its maximum of 120,000 Btu/hr, and with the 12 temperature settings, it can heat water from 100 F to 160 F maximum.

Remote control

Model NR50 does not include a remote control, but it is optional. The remote is recommended as it allows you to set the temperature of the outgoing hot water, use the flow meter alarm and if something goes wrong with the heater diagnose the problem by using the error codes.

Without the remote you won't have an access to the error codes for easier troubleshooting, but the lamps located on the front of the unit, will flash if the problem occurs.

Safety

Noritz gas water heaters are pretty safe. They are equipped with several safety devices, which will turn the unit OFF if something goes wrong.

  • Safety lock-out
  • Flame sensor
  • Resin coated PC board
  • Automatic overheat protection
  • Optional freeze protection
  • Lighting protection system
  • Fan rotation detector

Warranty

As other Noritz hot water heaters, NR50 comes with the 12 year limited warranty on the heat exchanger, 5 years on other components and 1 year on labor.

Summary

Noritz NR50 is recommended for those users, who are singles or have a small family, don't have much space for heater mounting and who prefer keeping the gas device outside the living space. Noritz water heater NR50 is a small but powerful heating device, which is designed to provide high thermal efficiency (83%) and since it is Energy Star approved it is qualified for government grants and other applicable utility rebates.
