Richmond households running short on hot water often have a sizing mismatch tied to multi-generational living or a shared secondary suite, not a broken tank.

Quick answer
Running out of hot water in Richmond most often points to a tank that is undersized for current household demand rather than a defect, and it's especially common in multi-generational households or homes with a secondary suite sharing one tank. A technician can calculate actual peak demand and recommend whether a larger tank, a higher recovery rate unit, or a tankless system is the better long-term match.

Richmond has one of the higher rates of multi-generational households in Metro Vancouver, with extended families often sharing a single home across two or three generations. A tank sized decades ago for a smaller household frequently cannot keep pace once grandparents, adult children, and grandchildren are all drawing hot water through the same morning window.
This is one of the most common reasons CANRO gets called out in Richmond specifically for running-out complaints, more so than a mechanical failure of the tank itself.
Because full basements are uncommon in Richmond due to the high water table, water heaters are frequently installed in garages, and garage installations sometimes have gas line sizing set for a smaller unit installed years earlier. If a homeowner wants to upgrade to a higher recovery rate tank, the existing gas line and vent may need to be reassessed to support the larger burner input, which is worth confirming before assuming a straightforward swap will solve the shortage.
This is different from simply buying a bigger tank; recovery rate depends on burner size and gas supply, not gallons alone.
Many Richmond homes include a basement or ground-level secondary suite, and where that suite shares the main house's water heater rather than having its own unit, running out of hot water becomes a near-daily issue rather than an occasional one. Separating the suite onto its own dedicated tank or tankless unit is often the most effective fix, rather than repeatedly upsizing a shared tank.
| Situation | Recommended Approach |
|---|---|
| Suite shares main tank, frequent shortages | Install dedicated unit for the suite |
| Multi-generational household, single tank | Assess for larger tank or tankless system |
| Only occasional shortage during guests | Larger tank may be sufficient without tankless |
| Gradual decline in duration over time | Check for sediment or component wear first |
A household with staggered showers spread across the morning may do fine with a standard tank, while a household where several people shower within the same 30-minute window needs either a much larger reserve or a faster-recovering unit. A technician measuring actual usage patterns, rather than just counting bathrooms, gives a far more accurate sizing recommendation.
If you smell gas (a rotten-egg odour) anywhere near the water heater or tankless unit, do not flip switches or search for the leak yourself. Leave the home immediately and call FortisBC at 1-800-663-9911 from outside. Any work on gas lines, venting, or combustion components must be done by a Technical Safety BC licensed gas fitter.
For homes with sustained, spread-out demand across a large household, a properly sized tankless system can eliminate the running-out problem entirely since it heats on demand rather than relying on a fixed reserve. Expect a ballpark (not a quote) of $3,500–$7,500 for tankless installation, with actual cost depending on gas line upgrades and venting access specific to garage or crawlspace installations common in Richmond.
For a straight tank replacement sized for higher demand, cost is set by venting complexity and access rather than a fixed figure, reflecting how much that varies across Richmond's housing stock, and is confirmed after a short in-home assessment.

Often yes. A tank sized for a smaller household years ago can fall well short once several generations share the same morning routine, and this is one of the most common demand-driven complaints CANRO sees in Richmond.
In most cases, yes, especially if hot water shortages are frequent. Separating the suite onto a dedicated unit resolves the conflict rather than repeatedly upsizing a shared tank.
Possibly. Higher recovery rate tanks need adequate gas supply, and older garage installations may need the line reassessed before upgrading.
It can be, particularly where demand is spread over a longer period rather than several fixtures running at the exact same instant.
If the shortage has been steady since move-in, it's likely sizing. If a previously adequate tank has gradually started running out sooner, suspect sediment buildup or component wear instead.
