Noritz has been building tankless water heaters for decades, and you'll find plenty of them in Damascus homes. When one throws an error or loses heat, the fix is usually straightforward — if you have someone who knows the unit.
Noritz symptoms we fix
- Error codes (ignition failure, flame loss, or combustion/vent related)
- Water gets hot, then cold, then hot again
- Fan runs but no ignition
- Low flow at the tap
- Unit beeps or displays a maintenance warning
- Visible scale or white residue at the inlet filter
Common Noritz fixes
Cleaning or replacing the flame rod, clearing vent blockages, fixing low gas pressure, cleaning the inlet water filter, and descaling the heat exchanger. On older non-condensing models, we also check the stainless vent for corrosion.
Damascus homes: what we see
We see a lot of first-generation Noritz units in Damascus homes from tank-to-tankless swaps 12–18 years ago. Many are due for either a thorough service or replacement.
Damascus has a mix of public water and private wells on larger lots. Well water is often harder and can carry sediment, so tank heaters benefit from yearly flushing and tankless units may need descaling more than once a year.
Repair vs. replace
A Noritz that's 15+ years old with a failing heat exchanger is usually a replacement candidate. Anything else — sensors, igniters, fans, circuit boards — is typically worth repairing. We'll lay out both options with prices.
New Noritz installs
Current condensing Noritz models (such as the EZ series, designed as a tank replacement) can often use your existing water and gas connections with minimal changes. We still verify gas line size and vent length before recommending one.

Frequently asked questions
What does Noritz error code 11 mean?
It generally indicates an ignition failure — often gas supply, a dirty flame rod, or venting. We diagnose the root cause instead of just resetting it.
How often should I service my Noritz in Damascus?
Annually, including descaling and a filter cleaning.
Is Noritz or Navien better?
Both are solid. The right choice depends on your gas line, venting options, and hot water demand. We install and service both.
Can a Noritz replace my tank heater?
Yes. Some Noritz models are specifically designed for tank-replacement installs.
