Electric heating · dollar scenarios
How much can a smart thermostat really save in Quebec?
Calculate realistic annual savings from heating schedules, compare published benchmarks and separate ordinary thermostat savings from Hilo Flex D peak pricing.
The short answer
There is no universal percentage for Quebec electric baseboards. ENERGY STAR reports about 8% average heating-and-cooling savings for certified thermostat services using U.S. field data, while Hilo reports an estimated average of $150 for participating Flex D customers during winter 2025–2026. Use your own heating cost, occupancy and setback habits; do not apply either figure blindly to the total electricity bill.
A home that is empty for predictable periods or still uses inconsistent manual settings.
A continuously occupied home already following an optimized schedule, or an incompatible heating circuit.
Heating can dominate winter electricity use in Quebec, but savings depend on when temperature can be reduced without comfort, moisture or freeze risk.
Before shopping
Five checks that eliminate the wrong choices
Complete these checks in order. One physical or electrical incompatibility matters more than ten app features.
- 01
Estimate the annual cost attributable to heating, not the total bill.
- 02
Record current setpoints for occupied, sleeping and away periods.
- 03
Confirm each thermostat’s voltage, load and heater compatibility.
- 04
Count all zones and installation costs before calculating payback.
- 05
Compare 12 months of weather-adjusted use after installation.
Useful comparison
Three numbers people confuse
A field-data benchmark, a utility pricing-program result and a personal simulation answer different questions.
| Number | What it means | How to use it |
|---|---|---|
| About 8% | ENERGY STAR average on heating and cooling bills for certified thermostat services | Context only; not a Quebec-baseboard guarantee |
| Up to 20% | Hilo’s published winter-bill headline with Flex D | Requires tariff participation and peak-event management |
| $150 average | Hilo estimate for full-season 2025–2026 participants under stated conditions | Do not present it as validated or universal |
| Your calculator result | Heating cost × modeled reduction | A planning scenario, not a forecast |
Personal calculation
Heating-savings calculator
Model 5%, 8% or your own cautious percentage against the heating portion of the bill.
A mathematical scenario, not a forecast. Weather, occupancy, settings and rates can change the result.
Action plan
Measure savings instead of guessing
Build the baseline
Use Hydro-Québec consumption history and identify comparable cold months before the change.
Change one strategy
Start with schedules in representative zones so hardware, weather and behaviour do not all change at once.
Normalize the result
Compare heating degree conditions, occupancy and tariff events. A warmer winter is not a thermostat saving.
Your situation changes the answer
Three concrete scenarios

FAQ
Common questions before buying
Will a smart thermostat save 20% automatically?
No. Hilo’s “up to 20%” relates to winter billing with Flex D and peak management. It is not a universal hardware saving.
Should I multiply 8% by my whole electricity bill?
No. The ENERGY STAR figure applies to heating and cooling costs in its program context. Estimate the heating portion first and disclose that the benchmark is not specific to Quebec baseboards.
What creates the savings?
Lower setpoints during sleep or absence, fewer forgotten high settings and, for Flex D, reduced peak consumption. Connectivity alone does not reduce heat loss.
How long should I measure?
Use a full heating season when possible and compare weather, occupancy and tariffs. One mild month can be misleading.
