Product Overview

  • Most versatile tankless water heater with the most vent options
  • Eco-friendly, Ultra Low Nox burner
  • Highest-grade dual stainless steel heat exchanger for longer life
Engineered expressly for the North American residential market, the EZ Series of high-efficiency, condensing tankless water heaters from Noritz America are designed to cut installation time and cost when replacing larger, storage tank-type units. The ENERGY STAR-rated EZ98-DV and EZ111-DV (Energy Factor: 0.97) join the previously released EZTR40 to provide professional installers and their homeowner-customers with a wider range of tankless options, covering the majority of residential, tank-replacement opportunities. The Noritz EZ Series heaters are the best solution for an easy tankless installation.
  • Both new EZ models have their hot- and cold- water connections located on top of the unit not the bottom, like most tank less heaters, this positioning allows the flexible water lines used by the previous tank heater to be quickly and easily reconnected to the new unit
  • Optimizes the perfect air/fuel ratio based on demand for better efficiency with less moving parts
  • Inside each EZ model are 2-stainless steel heat exchangers that have a greater resistance to corrosion and scale buildup than other materials, thereby boosting system life
  • Noritz connect app is compatible with both of the new units, allowing for wireless remote control of -heater functions, as well as diagnostic and maintenance reminders
  • Endless hot water
  • Energy savings
  • Space savings
  • High efficiency
  • Durable

Can this be installed in the attic? I have a tank water heater in the attic that i need to replace.
Asked by: HarryV
It heats water. If you put cold water in, you get hot water out. It doesn't care where in the house you put it as long as it has water, gas/electricity, and proper venting.

Can the exhaust be vented through the roof and the intake be vented through the side wall?

Can the exhaust be vented through the roof and the intake be vented through the side wall?
Asked by: stephen
Yes, just be sure your DIP switch settings are correct. Don't have manual handy but you'll set DIP switch for same as interior air setting in manual. Basically it tells the heater air is coming from different air pressure locations. If this is attic installation you can bring intake out of attic and not go through side wall with this same DIP setting
