Common Problems with Rinnai Tankless Water Heaters
Rinnai tankless water heaters are designed for durability, but occasional problems can arise due to
mineral buildup, gas flow issues, or electronic malfunctions. Here are the most frequent issues we repair:
1. No Hot Water or Inconsistent Temperature
- A clogged heat exchanger, gas valve issue, or air in the gas line can cause heating failure.
- Low water pressure or incorrect thermostat settings can also lead to temperature fluctuations.
2. Rinnai Tankless Water Heater Error Codes
- Error Code 10 – Venting issue due to blockages in the exhaust system.
- Error Code 11 – Ignition failure caused by low gas supply, faulty igniter, or clogged burner.
- Error Code 12 – Flame failure, often due to dirty flame rods or gas pressure issues.
- Error Code 16 – Overheating from mineral buildup or a malfunctioning heat exchanger.
- Error Code 19 – Electrical grounding issue, requiring wiring inspection and repair.
- Error Code 29 – Condensate drain blockage, often due to clogged pipes or improper installation.
- Error Code 33 – Faulty heat exchanger thermistor, leading to temperature fluctuations.
- Error Code 51 – Gas leak detected, requiring immediate shutdown and professional repair.
If your Rinnai unit displays any of these
error codes, contact CANRO Heating & Cooling for immediate assistance.
3. Low Water Pressure or Flow Issues
- Clogged inlet water filters and sediment buildup in pipes can restrict water flow.
- Faulty water flow sensors or low supply pressure can cause fluctuating temperatures.
4. Water Leaks from the Unit
- Leaks can result from loose fittings, a damaged heat exchanger, or a corroded valve.
- High-pressure buildup inside the system can also lead to leaks.
5. Strange Noises (Banging or Clicking Sounds)
- A clogged burner or trapped air in the gas line can create unusual noises.
- Mineral deposits inside the heat exchanger can lead to whistling or popping sounds.
If you are experiencing any of these problems, call

Expert insights: Rinnai tankless water heaters in Metro Vancouver
Here is how tankless water heaters work in the context of Metro Vancouver's climate, codes and homes. Rinnai is Japanese (Nagoya, 1920), best known for its RUR Sensei super-high-efficiency tankless and RX residential boilers. The brand's strengths are industry-pioneering tankless engineering, exceptional DHW reliability, durable heat exchangers.
BC's building code, TSBC gas-fitting rules, and FortisBC's natural-gas service standards together govern every HVAC installation in Metro Vancouver — CANRO works under permit and inspection on every gas-appliance install. CANRO has worked with Rinnai systems across Metro Vancouver since 1999, from older retrofits in White Rock and Westwood Plateau to new builds in Seafair and Cloverdale. Rinnai is generally a strong fit for tankless purists, customers who want 20+ year DHW lifespan, and gas-only installs.
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 Rinnai tankless water heater issues CANRO diagnoses
Over 25+ years of Rinnai service calls across Metro Vancouver, the recurring issues we see are: recirculation timer programming issues, flow-sensor scaling, condensate-line freezing in unheated spaces.
Parts availability. Rinnai parts are stocked locally and most repairs are completed same- or next-day.
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

Rinnai Tankless water heater FAQs
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.
Can a tankless run two showers at once in a Vancouver (Rinnai) 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.
