Our take on the Noritz EZ111 Residential 199.900 BTU Natural Gas Tankless Water Heater

The Noritz EZ111 is a residential natural gas tankless water heater rated at 199,900 BTU, the top of Noritz's EZ line. It heats water on demand instead of storing it in a tank, so it frees up floor space and never runs out of hot water. The EZ series is built for straightforward replacement of an existing tank, with common venting and gas connections that simplify installation. It suits households with high simultaneous hot-water demand, such as two bathrooms plus a kitchen, and competes with high-capacity tankless units from Rinnai and Navien on output and flow.

Questions and answers

Is the Noritz EZ111 big enough for a whole house?
At 199,900 BTU it handles a large home with multiple bathrooms, but simultaneous showers plus laundry can stretch its flow. Size it against your peak fixture demand.
Does it work with a standard tank water heater replacement?
The EZ line is designed to simplify replacing an existing tank, but it still needs a suitable gas supply, venting and condensate handling. A licensed installer should confirm your setup.
What maintenance does it need?
Plan on annual descaling, especially with hard water, plus a check of the venting and inlet filter. Skipping it can shorten the unit's life and affect the warranty.
How does it compare with Rinnai and Navien tankless models?
It matches them on high-BTU output and on-demand heating. Noritz's EZ line leans toward easier replacement installs, while rivals offer comparable flow and their own venting options.
Can it run on propane?
This model is configured for natural gas. A propane version would need a conversion kit or a different model, so confirm before buying.
What is in the box?
The unit itself, mounting hardware and installation documentation. Venting, gas connectors and valves are usually bought separately for the install.
Where is the Noritz EZ111 Residential 199.900 BTU Natural Gas Tankless Water Heater cheapest?
