A failing water heater raises a lot of questions fast. Here's what a Metro Vancouver homeowner should ask before deciding on repair versus replacement, tank versus tankless, and what a proper installation actually involves.
Tell us what you need—we’ll call you back fast.
Quick answer: Before replacing a water heater, ask: what caused it to fail, is it worth repairing instead, what size and type fits your household, gas or electric, tank or tankless, what will installation cost including venting and permits, and is a Technical Safety BC permit required? A licensed CANRO technician can answer all of this during a free written quote.

Most tank-style water heaters in Metro Vancouver last somewhere between 8 and 12 years, with hard water deposits and sediment buildup common in older homes shortening that lifespan further. Tankless units, when properly maintained, can last considerably longer. The most common signs a replacement is coming are rusty or metallic-tasting hot water, a tank that's leaking from the body rather than a fitting, popping or rumbling noises from sediment buildup, inconsistent water temperature, or a unit that's simply reaching the end of its typical service life. Before scheduling anything, it helps to understand what's actually happening so you can ask the right questions when a technician arrives.
The first question worth asking is whether the unit can be reasonably repaired instead of replaced. A leaking valve, a faulty thermostat, or a failed heating element (on electric units) are often repairable. A leak from the tank itself, corrosion, or a unit already near or past its expected lifespan usually points toward replacement, since sinking repair costs into an aging tank rarely pays off.
A homeowner can safely check the age of the unit (usually on a manufacturer's label), look for visible pooling water or rust around the base, note whether the pilot light (on gas units) is burning blue and steady, and check that the temperature setting hasn't drifted. What should not be attempted without a licensed technician: opening or servicing the gas control valve, disconnecting or modifying gas lines or venting, any electrical wiring changes, or draining and flushing a tank you're not familiar with, since these involve gas-fitting and electrical work that BC law requires be performed by licensed trades.

| Type | Typical Installed Cost (before rebates) | Good Fit When |
|---|---|---|
| Conventional gas/electric tank | Varies by size and fuel type — ask for a written quote | Straightforward like-for-like replacement, existing venting/gas line adequate |
| Tankless water heater | $3,500-$7,500 | Space is limited, continuous hot water is wanted, existing gas line can support higher demand |
| Heat pump water heater | Ask for a written quote; explore current rebate programs | Electric homes looking to reduce operating costs, adequate space for the unit |
Questions to ask a technician when comparing options: Does my existing gas line and venting support a tankless unit, or would upgrades be needed? Is there enough space and clearance for the unit I'm considering? How does expected energy use compare between options for my household size? What is the realistic installed cost once venting, gas line work, and permits are factored in, not just the unit price?
A proper in-home visit should include an assessment of your current unit's condition, the existing gas line or electrical circuit capacity, venting configuration, and available space, along with a walkthrough of the type and size options that fit your household. Ask for a written quote that spells out the unit cost, labour, any venting or gas line modifications, permit fees, and removal/disposal of the old unit, so there are no surprises later. It's reasonable to ask whether the quoted price is firm or could change once the installer sees behind the existing unit.
Gas water heater installations and replacements in BC generally require a Technical Safety BC gas permit, and any electrical work involved in an electric or heat pump water heater installation may require an electrical permit. A licensed contractor handles pulling the permit and coordinating any required inspection as part of the job. It's worth asking directly: will you pull the permit for this job, and is inspection included in the quoted price? This protects you if there's ever an insurance question or a future home sale.
Ask what current programs might apply to your replacement. The Canada Greener Homes program now offers an interest-free loan of up to $40,000 for eligible upgrades (the earlier grant program closed to new applicants in early 2024), and the Oil to Heat Pump Affordability program may apply if you're moving away from an oil-fired system. CleanBC, BC Hydro, and FortisBC also run rebate programs that can change over time, so it's worth asking your technician to confirm exactly what you currently qualify for and the current dollar figures at the time of your quote, rather than relying on outdated numbers.
⚠️ Safety note: If you ever smell gas (a sulfur or rotten-egg odor) near a gas water heater, do not flip switches, light anything, or use your phone inside the home — leave immediately, get everyone out, and call the FortisBC gas emergency line at 1-800-663-9911 from a safe location. If you notice soot around the draft hood, a pilot light that burns yellow instead of blue, or you experience headache, dizziness, or nausea near the unit, treat it as a possible carbon monoxide issue: leave the home, get fresh air, and call for help. Any gas line, venting, or electrical work on a water heater in BC must be performed by a licensed contractor — CANRO technicians hold Technical Safety BC gas licence LGA0043870 and are Red Seal certified.
