Common Problems with Navien Tankless Water Heaters
If your Navien tankless water heater is malfunctioning, it may show
error codes, temperature fluctuations, or water flow issues. Here are some of the most common problems we repair:
1. No Hot Water or Inconsistent Temperature
- The system may have a clogged heat exchanger, air in the gas line, or a failing ignition system.
- A dirty water filter or low gas pressure can also prevent proper heating.
2. Navien Tankless Water Heater Error Codes
- Error Code E001 – Overheating issue due to clogged heat exchanger or faulty thermistor.
- Error Code E003 – Ignition failure, often caused by gas supply problems or a dirty burner.
- Error Code E004 – Air pressure abnormality, linked to a blocked venting system or fan motor failure.
- Error Code E012 – Flame loss due to unstable gas pressure or a dirty flame rod.
- Error Code E016 – Heat exchanger overheating, often from mineral buildup or poor water circulation.
- Error Code E110/E111 – Exhaust gas recirculation issue, possibly from a venting system blockage.
3. Low Water Pressure or Flow Rate Issues
- A clogged inlet water filter or mineral buildup in the heat exchanger can reduce water pressure.
- Insufficient gas supply may prevent the unit from delivering hot water at full capacity.
4. Water Leaks from the Unit
- Leaks may result from a faulty pressure relief valve, damaged heat exchanger, or loose fittings.
- Corrosion or sediment buildup inside the unit can lead to water leaks and efficiency loss.
5. Strange Noises (Banging or Whistling Sounds)
- Mineral deposits in the heat exchanger can cause boiling sounds.
- A blocked gas line or faulty burner may lead to unusual noises during operation.

Expert insights: Navien tankless water heaters in Metro Vancouver
Selecting and servicing tankless water heaters in Metro Vancouver involves several local factors — climate, available rebates, code requirements — covered below. Navien is Korean (KD Navien, 1978), best known for its NPE-A2 tankless water heater and NCB-H combi boiler. The brand's strengths are best-in-class combi turn-down ratio, internal recirculation pump option, generous DHW output, strong warranty.
Vancouver's moderately hard tap water (around 60-100 ppm hardness in most of Metro Vancouver) affects tankless water heaters, combi boilers, and hot-water tanks — annual descaling is essential. CANRO has worked with Navien systems across Metro Vancouver since 1999, from older retrofits in White Rock and Kitsilano to new builds in Seafair and Newton. Navien is generally a strong fit for high-demand households (multiple bathrooms, family of 4+), townhouses without space for a tank, and combi conversions.
Technical considerations for tankless water heaters in Metro Vancouver
Sizing. Tankless sizing focuses on peak GPM (gallons per minute) at design temperature rise. Vancouver's 7-9°C incoming water needs about 32°C rise for typical use — most family installs need a 199,000 BTU unit.
Lifespan. Annual descaling is essential in Vancouver's moderately hard water — without it, scale build-up on the heat exchanger cuts capacity by 30% and shortens lifespan to under 10 years.
Warning signs. Tankless issues include flow-rate drops (scale), ignition lockouts (gas pressure or flame-rod fouling), condensate-trap clogs, and recirculation pump faults on units with built-in pumps.
Common Navien tankless water heater issues CANRO diagnoses
Over 25+ years of Navien service calls across Metro Vancouver, the recurring issues we see are: scale build-up in hard-water areas (annual descale required), flame-rod fouling, condensate-trap obstructions.
Parts availability. Navien parts are widely distributed across Metro Vancouver and ship next-day for most repairs.
What CANRO checks during a tankless water heater service
- Full descale of heat exchanger
- Flame-rod inspection and clean
- Combustion analysis
- Flow-sensor test
- Condensate trap clean
- Air-intake screen clean
- Gas pressure verification (inlet + manifold)
- Internal filter clean
- Error log download and review
- Recirculation pump check if installed

Navien Tankless water heater FAQs
Can a tankless run two showers at once in a Vancouver (Navien) winter?
Yes, with proper sizing. A 199,000 BTU condensing tankless will run two showers (at typical 1.8 gpm each) simultaneously through a Vancouver winter. For larger demand (3+ showers + dishwasher), consider linked tankless units or a combi boiler with built-in DHW recirculation.
What's recirculation, and do I need it?
Recirculation pumps return cooled hot water from the far fixture back to the tankless, eliminating the cold-water wait. Many modern tankless units (Navien NPE-A, Noritz EZ) have built-in recirculation. Worth the upgrade for homes where the kitchen or master bath is far from the mechanical room.
How long does a tankless water heater last?
A condensing tankless gas water heater installed by a qualified contractor in Metro Vancouver lasts 18-22 years with annual descaling. Without annual descaling, lifespan drops to 10-12 years.
How much hot water can a tankless deliver?
A 199,000 BTU tankless in Metro Vancouver delivers about 5-7 gallons per minute at a 32°C temperature rise (Vancouver incoming water is ~7-9°C). That handles two simultaneous showers comfortably, or a shower plus a dishwasher.
How often does a tankless need descaling?
Annually in Metro Vancouver's moderately hard water. Without descaling, scale build-up on the heat exchanger cuts capacity by 30% within 3-4 years and shortens lifespan to under 10 years. CANRO descales tankless units as part of every annual service.
Does tankless save money vs a hot-water tank?
Tankless gas water heaters cut operating cost 25-40% vs a tank because they eliminate standby heat loss. Upfront cost is higher ($3,500-$6,000 installed vs $1,800-$3,200 for a tank), but most homes recover the difference in 6-9 years on gas savings.
