Smart Thermostats 
For most Canadian homes: yes, but the payback varies by heating type and how you live.
A smart thermostat pays off fastest in a gas-heated home where the occupants have irregular schedules and currently heat at the same temperature all day. It pays off slowly, or not at all, in a home where the occupants are retired, home most of the time, and already manually adjusting their thermostat.
The Honest Answer
Smart thermostats don’t make your heating system more efficient at producing heat. They save money by running the system less, through smarter scheduling, setbacks when you’re away or asleep, and geofencing that responds to your actual location rather than a fixed schedule.
If you’re already doing all of this by hand, on a strict routine, a smart thermostat adds convenience but little additional savings. If you’re heating an empty house at full temperature because it’s easier than adjusting the dial, that’s where the savings come from.
Savings by Heating System Type
Gas-Forced Air (Furnace)
Best case for smart thermostat savings.
Setback schedules (turning the heat down when you’re away or asleep) reduce a gas bill. Industry estimates cite a 10–15% heating cost reduction for homes that make setbacks a habit. On a $150/month gas bill, that’s $15–22/month saved.
Real-world savings depend on how poorly the home was managed before. The “10–15%” figure comes from studies where thermostats replaced constant-temperature heating or homes run without any schedule at all.
Electric Baseboard Heating
Savings exist but are lower per unit of electricity saved.
Electric baseboard heaters are 100% efficient: every watt drawn becomes heat. There’s no efficiency gain to unlock. Savings come from running the heater less (during work hours, overnight setback, etc.). For homes where occupants are out most of the day, the savings can be significant. For homes where someone is home most of the time, the math is harder to make work.
The bigger win with baseboard smart thermostats is per-room control: you can keep common areas warm while cooling down unused bedrooms. This zone-specific control often yields savings that a single programmable thermostat cannot.
Heat Pumps
More nuanced, and easy to get wrong.
Smart thermostats save money on heat pumps, but the savings come with an important caveat: deep setbacks can be counterproductive for heat pumps.
When a heat pump returns to a much lower temperature after a long setback, it may need to run auxiliary (electric resistance) heat for a fast recovery, which costs far more than running the heat pump itself. The recommended approach for heat pumps is smaller, more frequent setbacks rather than large overnight drops.
ecobee’s eco+ system handles this automatically for heat pump users.
Electric Baseboard in Older Homes
Lower savings potential for always-occupied homes.
If someone is home all day (retirees, remote workers, caregivers), the heating runs most of the time anyway. A smart thermostat can optimize nighttime setback and per-room zoning, but the savings opportunity is smaller than in a home that’s empty 8–10 hours a day.
The Payback Math
| Scenario | Thermostat cost | Rebate | Net cost | Annual savings | Payback |
|---|---|---|---|---|---|
| Gas home, irregular schedule | $229 (ecobee Enhanced) | $75 | $154 | ~$180–$260 | Under 1 year |
| Gas home, consistent schedule | $229 | $75 | $154 | ~$60–$100 | 1.5–2.5 years |
| Baseboard, empty days | $119 (Mysa V2) | $50 | $69 | ~$80–$150 | Under 1 year |
| Baseboard, always home | $119 | $50 | $69 | ~$20–$50 | 1.5–3.5 years |
Estimates only. Savings depend on local energy rates, home size, insulation quality, and behaviour change.
The rebate is the most underappreciated part of this calculation. A $75 rebate on a $229 thermostat changes the payback from “maybe 2 years” to “under 6 months” for a gas home with average habits. See Smart Thermostat Rebates in Canada by Province for what’s available in your province.
Pros
Genuine energy savings for homes with variable occupancy and gas heating. The evidence is solid, though individual results vary.
Remote control: adjusting the temperature from your phone before you arrive home is convenient and saves the energy of heating an empty house.
Room-by-room zoning: ecobee’s SmartSensors and Mysa’s per-thermostat-zone control let you stop heating rooms you’re not using.
Scheduling that sticks: programmable thermostats have been around for decades, but most people never get the programming right. Smart thermostat apps make scheduling easier to set and easier to maintain.
Demand-response enrollment: in provinces and states with utility demand-response programs, a qualifying smart thermostat can earn ongoing credits in addition to saving energy.
Cons and Who Shouldn’t Bother
If you’re home all day at a consistent schedule, the savings opportunity is small. You can achieve similar results by adjusting your thermostat manually before bed.
If your home is tiny or well-insulated, energy costs may be low enough that the percentage savings don’t add up to much in dollars.
If you have electric baseboard heating and you’re home most of the day, the payback period stretches out. It may still be worthwhile for convenience and remote control, but don’t count on major savings.
If you rent and your landlord pays the heating bill, you’re not saving yourself money, and installation may not be allowed or reversible depending on your lease.
Worth-It Verdict by Scenario
| Your situation | Worth it? |
|---|---|
| Gas heat, away 8+ hours most days | Yes, fast payback |
| Gas heat, mixed schedule | Yes, reasonable payback |
| Electric baseboard, empty during work hours | Yes, especially with rebate |
| Heat pump home | Yes, ecobee handles this well |
| Always-home retiree, constant schedule | Maybe, convenience value, slower payback |
| Renter on a fixed lease | Check with landlord; savings go to landlord if they pay heat |
Frequently Asked Questions
How much does a smart thermostat actually save?
Studies and utility data suggest 10–15% savings on heating costs for gas homes with variable occupancy. In dollar terms, that’s $100–$300/year for an average Canadian home, depending on gas rates and usage. Electric baseboard savings are harder to generalize. See How Much Can a Smart Thermostat Save on Heating Bills? for the detailed numbers.
Do smart thermostats pay for themselves?
In most cases, yes: within 1–3 years, for gas-heated homes with irregular occupancy in particular. With a rebate factored in, payback can be under a year.
Are smart thermostats worth it for electric baseboard heating?
Yes, most of all for homes empty during the day. You can set schedules and geofencing to stop heating rooms when they’re unused. For always-occupied homes, the payback is slower but per-room control and convenience still add value.
Do smart thermostats save money if you already have a programmable thermostat?
The savings from upgrading a working programmable thermostat to a smart thermostat are smaller, since you’re already capturing most of the scheduling benefit. The added value comes from geofencing (responding to your actual location), remote adjustments, demand-response enrollment, and better data.
Is it worth paying more for the ecobee Premium vs Enhanced?
The Premium is worth it if you want room sensors and air quality monitoring. For a small home where the thermostat location is representative of the whole space, the Enhanced is sufficient. See ecobee Smart Thermostat Review for the full comparison.
