Common Tankless Water Heater Issues in Tsawwassen
Tankless water heaters are designed for durability and efficiency, but like any complex system, they can develop problems over time. Here are some of the most common issues that homeowners in Tsawwassen may face, and how CANRO Heating and Cooling can help with
tankless water heater repair in Tsawwassen.
No Hot Water
One of the most common issues with tankless water heaters is a lack of hot water. This problem could stem from various causes, including a malfunctioning heating element, gas supply issues, or a problem with the electronic components. Our technicians are skilled at diagnosing and fixing these issues promptly, restoring hot water to your home.
Fluctuating Water Temperature
Inconsistent water temperature can be frustrating, especially if the water runs hot one moment and cold the next. This issue often arises from problems with the flow sensor, thermostat, or heating element. Our technicians have the expertise to quickly identify the root cause and repair the issue, ensuring consistent hot water.
Ignition Failures
Gas-powered tankless water heaters rely on an ignition system to start heating the water. If the ignition fails, the unit will not heat the water, leaving you without hot water. CANRO Heating and Cooling’s technicians are experienced in troubleshooting ignition systems, gas lines, and burners, resolving the problem to get your system back to working order.
Mineral Buildup
Tankless water heaters are particularly susceptible to mineral buildup, especially in areas with hard water. Over time, mineral deposits can accumulate on the heat exchanger, reducing the efficiency of your unit and causing issues such as low water pressure or inconsistent heating. Our repair services include descaling and flushing your system to remove these deposits and restore optimal performance.
Error Codes
Modern tankless water heaters are equipped with digital displays that show
error codes when something goes wrong. These codes can indicate a range of issues, from venting problems to electrical faults. Our technicians are familiar with the error codes for top brands like Navien, Rinnai, and Bosch and can quickly diagnose and fix the underlying issue.
Gas Leaks
Gas leaks are a serious safety concern and require immediate attention. If you smell gas near your tankless water heater or suspect a gas leak, turn off the gas supply and contact CANRO Heating and Cooling immediately. Our technicians are trained to detect and repair gas leaks, ensuring the safety of your home and family.

Expert insights: tankless water heaters in Metro Vancouver
Below is a CANRO technician's perspective on tankless water heaters as they apply in Metro Vancouver: what to look for, what to avoid, and what to expect. A condensing tankless gas water heater in Metro Vancouver delivers endless hot water at 90%+ efficiency, fits on a wall (reclaiming 25 sq ft of floor space vs a tank), and lasts 18-22 years.
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 tankless water heater systems across Metro Vancouver since 1999, including installations and service calls in Lonsdale, Maillardville, Maillardville and Hamilton.
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.
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

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