Two different ways to heat a home

A boiler and a heat pump both keep your home warm, but they go about it in fundamentally different ways, and that difference drives everything else. A gas boiler burns natural gas to heat water, then circulates that water through radiators, baseboards, or in-floor tubing. It is a hydronic system, and the warmth it delivers is the steady, quiet, draft-free comfort many homeowners prize.

A heat pump does not burn fuel at all. It uses electricity to move heat from one place to another, pulling warmth out of the outdoor air and delivering it indoors. Most heat pumps in Metro Vancouver are air-source units that heat and cool the air, delivering it through ducts or ductless indoor heads. There is also the air-to-water heat pump, which delivers its heat to water and can feed a hydronic system much like a boiler does, but with electricity instead of gas.

So the honest framing is not simply boiler versus heat pump, but hydronic gas heat versus electric heat that can also cool, with an air-to-water option bridging the two. Understanding that shapes a better decision than a straight head-to-head.

The biggest single difference: cooling

If there is one fact that decides many Metro Vancouver homeowners, it is this: a heat pump also cools your home in summer, and a boiler does not. A boiler only heats. A heat pump runs in reverse in warm weather, moving heat out of the house to provide air conditioning.

This matters more here than it used to. Our summers have grown warmer, and many homes that were built to shrug off heat now get uncomfortable. A boiler-heated home needs a separate cooling solution if the owner wants relief in summer, whereas a single heat pump handles both seasons. For a household that wants heating and cooling from one system, that is a strong point in the heat pump's favour, and it is worth weighing honestly against the comfort character of hydronic heat.

Comfort and heating style

Comfort is where a boiler still has genuine appeal. Hydronic heat from a boiler is even, quiet, and free of blowing air, and radiant floors add warm surfaces underfoot that forced air simply cannot replicate. For homeowners who dislike drafts or find forced air drying and uneven, a boiler-fed hydronic system is often the more comfortable heat.

A conventional air-source heat pump delivers forced air, so it has the responsiveness and the ability to filter and cool that come with moving air, but also the draft and noise character of any forced-air system. An air-to-water heat pump is the interesting middle path: it delivers the same hydronic comfort as a boiler through your existing radiators or floors, while using electricity and, in many configurations, providing cooling through a separate means. Which comfort profile you prefer is a personal call, and it is a legitimate part of the decision alongside cost and cooling.

Fuel and operating cost, framed honestly

Operating cost comes down to the price of the fuel and how efficiently each system turns it into heat, and both vary, so we will describe the shape of it rather than invent numbers.

A gas boiler runs on natural gas and, in a modern condensing unit, can be quite efficient at turning that gas into heat. Its operating cost tracks the price of gas. A heat pump runs on electricity, and its defining trait is that it moves several units of heat for each unit of electricity it consumes, which is why it can be efficient to operate even though electricity is priced differently from gas.

Which is cheaper to run in your home depends on local gas and electricity rates, your home's efficiency, and how the system is sized and used. It genuinely varies, and anyone who quotes you a firm savings figure without studying your home is guessing. The reasonable approach is to compare based on your actual house and current rates.

Up-front cost is a separate question again, and it too varies widely by system type and by what a retrofit involves.

Retrofit realities for a hydronic home

If your home already has a boiler and hydronic heating, the retrofit path shapes the decision heavily, and there are a few honest realities to know.

• Replacing a boiler with a boiler is usually the most straightforward path, since it reuses your existing loops, radiators, and floors. It keeps hydronic comfort but keeps you on gas and adds no cooling.
• Converting to an air-to-water heat pump keeps your hydronic emitters while moving to electricity. It works best with lower-temperature emitters like radiant floors; homes with small high-temperature radiators may need added emitter area or a hybrid setup, and cost varies with that complexity.
• Adding a conventional air-source or ductless heat pump for heating and cooling, alongside or instead of the boiler, is another route. Some homes keep the boiler for hydronic warmth and add a ductless system purely for cooling and shoulder-season efficiency.
• Hybrid arrangements, where a heat pump does most of the heating and a gas boiler assists in cold snaps, can be a sensible transition that captures most of the benefit while keeping backup on the coldest days.

There is no single correct retrofit; the best one depends on your emitters, your electrical service, your comfort priorities, and your budget. This is exactly the kind of question a licensed technician should assess for your specific home.

How cold-climate heat pumps perform on the coast

A fair comparison has to address the old worry that heat pumps cannot cope with winter. In Metro Vancouver's mild, wet coastal climate, that concern is largely outdated. Modern cold-climate heat pumps are designed to keep producing useful heat well below freezing, and our winters are mild rather than extreme, so a properly sized heat pump can carry the great majority of the heating season here.

Output does fall as it gets colder, and genuine cold snaps do occur, which is why good designs include backup heat or, in a hybrid arrangement, an assisting boiler for the coldest stretches. The damp coastal air also means outdoor units run normal defrost cycles. None of this undermines the heat pump; it just means the system has to be sized and configured for our actual conditions. Compared with the colder parts of Canada, the coast is a relatively easy environment for a heat pump to do well.

Electrification and rebates

Part of the boiler-versus-heat-pump decision is where you want your home to sit on fuel. A heat pump reduces or eliminates on-site gas use, which appeals to homeowners focused on electrification, while a gas boiler keeps you on natural gas. That choice can carry incentive implications, because current programs tend to encourage the electric path.

Programs that may apply to an eligible heat pump upgrade include CleanBC and Better Homes BC, FortisBC, BC Hydro, the interest-free Greener Homes Loan, and the Oil to Heat Pump Affordability program for homes moving off heating oil. Two caveats matter. First, the Canada Greener Homes Grant closed to new applicants in early 2024, so do not count on that grant. Second, eligibility rules and dollar amounts change and depend on your situation, so confirm current details directly with each program before assuming any rebate rather than relying on a figure you saw elsewhere.

So how should you choose?

There is no universal right answer, and any honest contractor will tell you the same. The decision turns on a handful of questions about your specific home:

• Do you want cooling as well as heating? If yes, a heat pump does both from one system, while a boiler heats only.
• Do you value hydronic comfort and warm floors? A boiler, or an air-to-water heat pump, preserves that; conventional forced-air heat pumps do not.
• Do you want to reduce on-site gas use and pursue electrification and rebates? That points toward a heat pump.
• What does your existing system and home allow? Your emitters, electrical service, and layout shape which retrofit is practical and affordable.
• What matters most on budget: lower up-front cost, lower operating cost, or long-term flexibility? These can pull in different directions.

For many Metro Vancouver homes the sensible outcome is not purely one or the other but a thoughtful combination, such as keeping hydronic heat and adding cooling, or moving to an air-to-water heat pump with sensible backup.
