Boiler vs. Furnace: Which Is Right for Older West Vancouver Homes?
Radiators or forced air? Older West Vancouver homes run on both, and replacing one with the other is a big, expensive decision. Here's how boilers and furnaces actually compare — comfort, cost, lifespan, and what your home's existing setup should tell you.

Usually: replace like with like.
In most older West Vancouver homes, the cheapest, least disruptive upgrade is to replace your existing system with a modern version of the same thing — a new boiler where a boiler sat, a new furnace where a furnace sat. Ripping out radiators to add ductwork (or vice versa) adds serious renovation cost. That said, there's a third option many homeowners here are choosing: a cold-climate heat pump, which can deliver the biggest operating savings of all. Below, the honest comparison.
Boiler vs. furnace: the fundamentals.
A furnace heats air and pushes it through ducts to every room. A boiler heats water and circulates it through radiators, baseboards, or in-floor piping. Same job — warmth — completely different feel. Here's how they stack up for an older home on the North Shore.
1. Comfort feel
Boilers win on comfort. Radiant heat warms objects and surfaces, not just air, so rooms hold an even temperature with fewer drafts and cold corners — a real difference in older Ambleside and Dundarave homes with tall ceilings and big windows. Furnaces heat up faster, but the air they push can feel dry, and temperature swings between blower cycles are more noticeable.
2. Noise
Boilers are nearly silent — just a burner hum and water circulating. Furnaces have blowers, and in older homes the ductwork itself can pop, rattle, or whistle. If a bedroom sits above or beside the mechanical room, boiler households sleep better.
3. Air quality and allergies
A furnace moves air, which means it moves dust, pet dander, and pollen along with it — though a good filtration setup on the furnace side can help with this. Boilers don't circulate air at all, so they don't spread airborne allergens. For allergy-sensitive households, hydronic heat is the gentler option.
4. Lifespan and maintenance
Boilers have fewer moving parts, so they tend to outlast furnaces — a well-maintained boiler can run 20 years or more, while furnaces typically last 15 to 20. Furnaces need more hands-on care: filter changes every few months, blower and burner checks. Boilers need an annual service, and the system itself is largely set-and-forget.
5. Upfront cost and disruption
This is where your home's existing infrastructure decides. Swapping an old boiler for a new condensing boiler is a straightforward job — the pipes, radiators, and gas line are already there. Swapping an old furnace is likewise simple where ducts exist. But converting between the two means installing ductwork or piping through a finished older home, which adds major cost and disruption. Pricing depends on the equipment, the fuel, and your home's layout — that's why every quote we give starts with a free in-home assessment, not a guess.
6. Summer cooling
Furnaces have one built-in advantage: the same ductwork can carry an air conditioner. Boiler homes have no ducts, so adding cooling later means ductless mini-splits. If air conditioning matters to you — and North Shore summers keep getting hotter — factor that into the decision.
Combi boilers changed the math.
If your older home runs on a boiler and you're replacing it, ask about a combi (combination) boiler. It heats your home and produces on-demand hot water from one compact, wall-hung unit — no separate hot water tank taking up floor space in the mechanical room. For smaller West Vancouver homes and townhomes, that reclaimed space alone can be worth it.
We install and service combi boilers and tankless water heaters, so if your hot water setup is aging alongside the boiler, both can be sorted in one visit.
What about a heat pump instead?
More West Vancouver homeowners are skipping the boiler-or-furnace question entirely. A cold-climate heat pump installation from $13,000 replaces the furnace outright, handles heating and cooling in one system, and switching from fossil-fuel heat can currently unlock up to $21,500 in combined BC rebates — money you won't see when replacing gas-for-gas.
Homes with radiators keep them as backup or remove them during the swap; every home gets a proper heat-load calculation so the system is sized right. If you're already paying for a heating replacement, pricing a heat pump alongside the boiler/furnace quote costs you nothing — and the answer might surprise you. Rebate programs change, so we'll confirm your eligibility during the free assessment.
Watch for these in older homes.
British Properties estates often have hydronic systems feeding in-floor zones — keep them; the infrastructure is too good to abandon. Waterfront homes should have boilers or furnaces sited with salt air in mind for longevity. And hillside lots in the British Properties and Upper Lands often make outdoor unit placement tricky, so equipment siting is part of every quote we do. Whatever you choose, a proper installation by our own crew is finished in a single day in most cases, quoted at one fixed upfront price.
A simple decision rule.
Happy with radiators and no ducts? Replace the boiler with a modern condensing or combi boiler. Have ductwork and want air conditioning down the line? A new furnace is the practical choice. Either way, get a heat pump quoted next to it before you commit — it's the comparison that can cut your heating bill and your rebates stack highest against. Not sure how much life your current furnace has left? That's a good place to start, and our fall maintenance checklist will help you keep whatever you have running until you decide.
Common questions
Is a boiler or furnace better for an older home in West Vancouver?
It usually comes down to what your home already has. Older homes with radiators or in-floor heating are best served by a modern condensing or combi boiler — keeping the existing piping avoids a costly conversion. Homes with ductwork are better suited to a new furnace, which can also pair with air conditioning. A cold-climate heat pump is worth pricing alongside either option for the operating savings and BC rebates.
Can you replace a boiler with a furnace in an older home?
Yes, but it's a much bigger job than a like-for-like replacement. Converting from hydronic to forced air means installing ductwork through a finished home, which adds significant cost and disruption. Most homeowners find a modern boiler replacement — or a heat pump — delivers better value than a full conversion.
Do boilers last longer than furnaces?
Generally, yes. Boilers have fewer moving parts and no blower or air filter to wear out, so a well-maintained boiler can run 20 years or more, compared to 15 to 20 years for a typical furnace. Both need annual service to reach the top of that range.
Are combi boilers a good fit for West Vancouver homes?
Combi boilers are an excellent fit for smaller homes and townhomes because they heat the home and produce on-demand hot water from one wall-hung unit, eliminating the hot water tank. They work with existing radiator or in-floor piping, making them a natural upgrade for older boiler homes.
Can I get rebates for replacing my boiler or furnace?
The largest BC rebate streams reward switching from fossil-fuel heating to an electric heat pump — currently up to $21,500 in combined rebates for qualifying households. Replacing gas-for-gas generally qualifies for far less. Programs and eligibility change, so we confirm exactly what you qualify for during your free in-home assessment.
How much does boiler or furnace replacement cost in West Vancouver?
Pricing depends on the equipment, your fuel type, and your home's layout — like-for-like boiler or furnace swaps are far less expensive than conversions that add ductwork or piping. Every quote we provide is one fixed upfront price after a free in-home assessment, and heat pump installations start from $13,000 installed.
