No hot water in your Metro Vancouver home usually means a pilot light, thermostat, heating element, or sediment problem — but a few checks can tell you whether it is a simple fix or a job for a licensed technician.

Quick answer: If you have no hot water, first check your gas fireplace pilot light and breaker panel (electric water heaters) or verify the gas supply is on. If the tank is leaking, making loud rumbling noises, or you smell gas, shut off the water/gas and call a licensed technician immediately. Most no-hot-water calls trace to a failed thermocouple, pilot light, heating element, or a unit that has simply reached the end of its 10-15 year service life.

A sudden loss of hot water almost always comes down to one of a handful of causes: an extinguished pilot light or failed thermocouple on a gas tank, a tripped breaker or burned-out heating element on an electric tank, a gas supply interruption, a failed control valve, or a unit that has simply reached the end of its service life. In older Metro Vancouver homes and condos, mineral buildup from the region's moderately hard water can also insulate the heating element or clog a tankless unit's heat exchanger, gradually reducing hot water output until it stops altogether. Tankless (on-demand) water heaters have their own failure points, including flow sensor faults, ignition failures, and error codes displayed on the unit itself.
It matters whether the water is completely cold, lukewarm, or hot for a few minutes and then cold. Completely cold water usually points to a power or ignition failure, while hot-then-cold suggests a sizing issue, a failing element, or (on tankless units) a flow or venting problem. Noting which pattern you are seeing helps a technician diagnose the issue faster when they arrive.
Before calling for service, there are a few safe, no-tools checks most homeowners can do themselves. These do not involve opening the gas line, touching wiring, or disassembling any part of the unit.
If the pilot will not stay lit after a couple of attempts, if the breaker trips again immediately after resetting, if you hear rumbling, popping, or cracking from the tank, or if you see any water pooling at the base, stop troubleshooting and call a licensed technician — these are signs of a more serious fault, not something to keep testing.
In British Columbia, gas water heater repairs — including thermocouple, gas valve, or burner assembly replacement — legally require a licensed gas fitter, and electric water heater element or wiring repairs require a licensed electrician. This is a Technical Safety BC requirement, not just good practice, and it protects you from fire, carbon monoxide, and electrical hazards as well as insurance complications if unlicensed work causes damage.
| Symptom | Likely cause | Who should handle it |
|---|---|---|
| No hot water, pilot won't relight | Failed thermocouple or gas valve | Licensed gas fitter |
| No hot water, breaker trips repeatedly | Failed heating element or wiring fault | Licensed electrician |
| Rumbling or popping tank | Sediment buildup on the tank floor | Licensed technician (flush or replace) |
| Water pooling at the base | Tank leak or corrosion | Licensed technician — often replacement |
| Tankless unit showing an error code | Flow sensor, ignition, or venting fault | Licensed gas fitter |
| Lukewarm water only | Undersized unit, crossed valve, or failing element | Licensed technician for diagnosis |

📞 (604) 359-1081 Request a free quoteA CANRO technician arriving for a no-hot-water call will typically test the thermocouple or ignition system, check gas pressure and venting, inspect the heating elements and thermostat on electric units, look for sediment buildup, and check the tank or heat exchanger for leaks or corrosion. On tankless systems, this includes checking the flow sensor, descaling if mineral buildup is suspected, and confirming venting meets Technical Safety BC requirements. You will get an upfront, written explanation of what is wrong before any repair work begins.
Many issues, such as a thermocouple, gas valve, or single heating element, are repairable. If the tank itself has failed structurally, is leaking, or is near the end of its typical 10-15 year lifespan, replacement is usually the more cost-effective option since a repair on an old tank often just delays a bigger failure. A technician can walk you through both options with real numbers rather than guesswork.
Age is the biggest factor. A tank water heater under 6-8 years old with a single failed part is usually worth repairing. A tank over 10-12 years old that fails is often better replaced, since a second failure is likely soon after and older tanks are less efficient to begin with. Frequency of repairs matters too — if you have called for the same unit twice in a year, replacement tends to be the more economical path.
If replacement makes sense, CANRO provides a free written quote before any work begins. Installed pricing in Metro Vancouver for a standard tankless water heater typically falls in the $3,500-$7,500 range, depending on unit sizing, venting requirements, gas line adjustments, and permit costs. Every installation requires a Technical Safety BC permit, which a licensed contractor pulls on your behalf.
If your water heater needs replacing, it is worth asking about current incentive programs before booking the work. The Canada Greener Homes program now operates as an interest-free loan of up to $40,000 for eligible upgrades rather than the grant that closed to new applicants in early 2024, and the Oil to Heat Pump Affordability (OHPA) program may apply if you are switching away from an oil-fired system. CleanBC, BC Hydro, and FortisBC also periodically offer rebates on qualifying high-efficiency equipment. These programs change frequently, so confirm exact eligibility and dollar amounts at the time of your quote rather than relying on older figures you may have seen online.
⚠️ Safety note: If you smell gas anywhere near your water heater, do not attempt any troubleshooting, do not flip switches or light anything — leave the house immediately and call the FortisBC emergency line at 1-800-663-9911 from outside. If you notice soot, a burning smell, or headaches/dizziness near a gas water heater, treat it as a possible carbon monoxide issue: get everyone into fresh air right away. In BC, only a licensed gas fitter may service, repair, or reconnect gas water heater components, and only a licensed electrician may work on electric water heater wiring or elements — this is a legal requirement, not just a recommendation, so do not attempt gas or electrical repairs yourself.
