NC250 Commercial Tankless Water Heater

Noritz developed their commercial tankless hot water heaters with industry in mind. Maximizing output while maintaining high efficiency, these tankless water heaters save companies money and energy in a compact, efficient package. And since they link in series up to 24 units, your hot water supply can easily expand as your business does. For these and many other great products, contact the professionals at Bill Metzger Plumbing.
These tankless water heaters feature:

  • Designed to provide enough hot water to meet the demands of hotels, resorts, or housing complexes, these ASME certified units can link together to provide for your hot water needs
  • Adding a quick-connect cable allows the installer to quickly and easily connect 2 identical units to supply more hot water
  • Designed to work with a multi-unit system controller to connect up to 24 units to meet even greater hot water demands
  • Direct vent (DV) models draw air from the outdoors so they do not use any air from the indoor installation location, making them ideal for tight spaces or where indoor air is unsuitable for combustion
  • Direct ignition means no standby pilot light to waste energy
  • Commercial grade heat exchanger and fully modulated burner work together to provide increased efficiency, to stabilize temperature fluctuations, and boost performance of the flow rate for long life under heavy use
  • Corrosion-free stainless steel casing protects the unit and allows for more efficient cleaning which reduces labor and maintenance costs
  • Self-diagnostic onboard computer system, combined with the included digital remote, provides ease of maintenance and temperature adjustment.
