Replacing Electric Baseboard Heaters with a Heat Pump: A Brackendale Family's Plan for a Warmer Winter

Last October, a young family moved into a mid-nineties home in Brackendale with two small kids, one very large and very friendly dog, and a set of electric baseboard heaters that came with the place. Their first Squamish winter taught them exactly what those baseboards cost to run, one hydro bill at a time. In their own words, the baseboards were "not great" and "very expensive." By early summer, the running joke in the house was that if nothing changed before the cold came back, the backup plan was "warm curtains."

It is early August in the Squamish valley, and we realize winter heating is a strange thing to bring up while the trailhead parking lots are overflowing and half the valley is lined up for ice cream. Think of the neighbour who stacks firewood through a heat wave: it looks a little odd in the moment and completely brilliant in January. Heating decisions work the same way: if you want the new system running before the first cold snap, the planning has to happen while it is still warm.

Their situation is one of the most common in the Sea-to-Sky corridor: a solid older home, electric baseboard heat, a 100-amp panel, and a family wondering whether replacing electric baseboard heaters with a heat pump is actually doable. It is, in most cases. Even the electrical panel question, the one that stops many people before they start, usually has a workable answer.

Why baseboard heat costs so much in a Squamish winter

Electric baseboards are the space heaters of the heating world: simple, dependable, and expensive to feed. Every unit of warmth they make is a unit of electricity on your bill, one for one, all winter long. There is no efficiency lever to pull, which is why a cold snap shows up on your hydro bill with such enthusiasm.

A heat pump plays a different game entirely. Rather than making heat from scratch, it moves heat, pulling warmth out of the outdoor air (cold air still holds plenty) and delivering it inside, and moving heat takes far less electricity than manufacturing it. The Brackendale family put the outcome better than we could: the same warm house, "at a fraction of the cost of these baseboards."

The 100-amp panel question, answered first

We hear it all the time that an older home with a 100-amp panel simply cannot take a heat pump. Sometimes a homeowner has even had an electrician confirm the panel is close to capacity, which feels like the end of the conversation. That is rarely the end of it, because there are two ways to measure how full a panel is, and they give very different answers.

The traditional method comes from the electrical code. It works from a list of everything connected to the panel and assumes a day when nearly all of it could be running at once, which is a deliberately cautious way to count. Almost no household actually runs that way, so this calculation often says a panel is full when, in daily life, it is not.

The newer method uses twelve months of your home's actual BC Hydro usage instead. In our experience, the real number often comes back at fifty to sixty percent of what the old math suggested, which can free up roughly 40 percent more room on the panel than anyone thought was there.

The one catch is the calendar: you need a full year of usage history in the home before that data exists. For the Brackendale family, who moved in last October, the year arrives this fall, right on time to be ready for winter. If you have been in your home longer than a year already, the data is waiting for you now.

What replacing electric baseboards actually looks like

For most baseboard homes around Squamish, the answer is a small number of wall-mounted indoor units in the rooms where you actually live, connected to one outdoor unit by slim refrigerant lines. There is no ductwork to invent and no major renovation hiding inside the project. Lines can run through a closet or two, or along the outside of the house in low-profile covers, and the whole design gets worked out at the in-home consult before anyone drills anything.

Sizing is where a good design earns its keep. At the Brackendale consult we scanned the whole home and had a room-by-room heat loss number within minutes, and the family asked a question we hear at almost every consult: "What does the load exactly mean?" It means how much heat the house needs on the coldest design day, minus fifteen for our part of the valley, and it is the number every equipment decision hangs on.

Their main living space measures about eleven hundred square feet. The whole home needed less than two tons of heating capacity, so the sensible recommendation was a right-sized standard unit rather than an oversized flagship, which is a smaller bill on purpose.

Two more things surprised them, both pleasantly. First, not every room needs its own unit: their small bathroom already had a plug-in heater doing the job fine, and adding a unit there would have raised the cost of the whole system for no real gain, so we suggested keeping what works. Second, the old baseboards do not have to go anywhere: they get switched off at the panel and stay in the wall as a built-in backup, reconnectable in an afternoon if you ever want them.

The part your August self will appreciate: it cools too

Every heat pump we install heats and cools with the same equipment, which matters in a valley where summers have started arriving with opinions. During this summer's hot stretch, the family's shaded, north-facing downstairs held a civilized 22 degrees while the upstairs bedrooms cooked. Next summer, the same units that erase the baseboard bills will be keeping those bedrooms sleepable. One machine covers both seasons, and nobody has to think about warm curtains or box fans again.

Why late summer is the right time to plan

Nothing about winter improves by being ignored until it shows up. Planning a baseboard conversion in August or September means the design, the electrical details, and the installation can all land before the first real cold, and it means you are deciding calmly instead of shopping during a cold snap. If your panel needs the twelve-month usage data, the in-home consult can happen now so the design is ready the moment your year of history arrives. That is exactly how the Brackendale family set it up: consult done in the sunshine, installation aimed at fall, winter told to do its worst.

Thinking about your own baseboards?

Questions we hear about replacing baseboard heaters

Can a 100 amp panel handle a heat pump?

Often, yes. The code-based calculation is deliberately conservative, and the newer BC Hydro method based on twelve months of real usage frequently shows meaningfully more available capacity. An in-home consult looks at your panel both ways before anyone talks about an upgrade.

Do I have to remove my electric baseboards when the heat pump goes in?

No. They get disconnected at the panel and stay in place as a backup that can be reconnected quickly if you ever want it.

Does every room need its own indoor unit?

No, and small rooms usually should not have one, because each indoor unit pushes up the size and cost of the outdoor unit. Small spaces are often better served by what is already working there.

Will a heat pump keep my house warm at minus 15?

A properly sized system is designed around exactly that number, your home's measured heat loss on the coldest design day. Meeting that number is what the equipment gets chosen to do, so a cold snap is the condition the system was built for.

Is a heat pump cheaper to run than electric baseboard heaters?

Yes, meaningfully, because it moves heat instead of making it. Baseboards convert electricity to warmth one for one, while a heat pump delivers more warmth per unit of electricity, which is why baseboard homes see some of the clearest savings of any conversion.
