The Noritz EZ111DV enters 2026 as a significantly updated contender in the premium tankless market. The new EZ Series Pro combines a 199,900 BTU condensing burner with up to 11.1 GPM of hot-water capacity and a 0.98 UEF rating, putting it directly into the same performance class as the latest Rinnai SENSEI RX series. Noritz also gives the EZ111DV a remarkably long 25-year heat exchanger warranty, along with five years of parts coverage and one year of labor coverage. The 2026 refresh adds a built-in operation panel, EZ Start Plus Bluetooth connectivity, top-mounted water connections, and included natural-gas-to-propane conversion capability. These details are particularly useful when replacing a conventional tank or upgrading an existing tankless installation. Its main disadvantages are the heavier chassis and somewhat more specialized distribution network compared with Rinnai or Rheem. For homeowners who want flagship-level output and efficiency while placing significant value on long-term heat exchanger coverage, the EZ111DV is an exceptionally compelling choice.
