//Quick answer
- Tankless specialist with a long track record in the category.
- $4,000 to $6,000 installed; permit usually required.
- Non-condensing and condensing options change the venting requirements.
- Dealer or certified-installer status: not confirmed, not claimed.
01Definition
What is Noritz known for?
Noritz is a Japanese manufacturer that has built tankless water heaters for decades and sells both condensing and non-condensing residential units in the United States. The breadth of the line matters on a retrofit: a non-condensing unit can sometimes reuse a simpler venting path, while a condensing unit needs its own venting and a condensate drain.
What does a Noritz install involve?
Gas supply sized for the burner, venting matched to the unit type, water connections with isolation valves, power for the controls, and a condensate drain on condensing models. Done-Rite handles the gas, venting and condensate work as part of the install, and pulls the permit when one is required.
02When it applies
When does Noritz fit?
Retrofits where the venting path favors one unit type over another, and households that want a straightforward tankless without a recirculation system. It is also a common choice when replacing an existing Noritz.
When would the crew suggest a different brand?
When the house wants built-in recirculation, or when the venting and fit favor another unit. All three brands are installed and serviced by the crew; the pick is about the installation, not the badge.
03What goes wrong
What goes wrong?
Scale from hard water without periodic descaling, and undersizing for simultaneous demand. A water test and a proper sizing conversation prevent both.

Common questions
$4,000 to $6,000 installed.
Both are units Done-Rite installs and services. The right one depends on the installation: venting path, gas supply and whether recirculation is wanted. The three-way comparison lays it out.
