How Smart Thermostats Save Money
A traditional thermostat holds a constant temperature — heating your home the same amount whether you are at work or sleeping. A smart thermostat learns your schedule and automatically:
- Reduces heat when you leave for work
- Warms up the house before you return
- Sets back temperature while you sleep
- Detects when you leave unexpectedly (geofencing)
- Responds to real-time weather data
The result is 10–25% reduction in heating and cooling energy compared to a manually operated conventional thermostat.
Annual Savings Estimate
| Heating Spend | Smart Thermostat Savings (15%) | Cooling Savings (10%) |
|---|---|---|
| $1,000/year heat, $200/year cooling | $150 + $20 = $170/year | — |
| $1,500/year heat, $300/year cooling | $225 + $30 = $255/year | — |
| $2,000/year heat, $500/year cooling | $300 + $50 = $350/year | — |
Savings depend heavily on your current thermostat habits. If you already manually adjust your thermostat frequently, the incremental gain is lower than for households that set-and-forget.

Installation
Most smart thermostats install in 20–30 minutes for someone comfortable with basic wiring. Key steps:
- Turn off power to the furnace at the breaker
- Remove old thermostat and photograph the existing wiring
- Check compatibility (most smart thermostats require a “C wire” for constant power — many older homes don’t have one)
- If no C wire: Ecobee includes a Power Extender Kit (PEK); Nest installs a “G wire” alternative or uses an add-a-wire adapter
- Connect wires per the app’s step-by-step guide (both Ecobee and Nest have excellent visual guides)
- Mount the new thermostat and restore power
- Complete app setup
When to hire an electrician: If your home has electric baseboard heaters, hire an electrician for the first installation — line voltage (240V) work is not DIY for most homeowners.
Smart Thermostat + Utility Demand Response Programs
Several Canadian utilities offer “demand response” programs where they briefly cycle back your thermostat during peak grid demand (usually summer afternoons). In exchange, you receive bill credits:
| Program | Province | Benefit |
|---|---|---|
| Hydro-Québec Hilo | QC | $100–$200/year in credits |
| BC Hydro Demand Response | BC | Bill credits |
| OEB-regulated demand programs | ON | Varies by utility |
These programs are voluntary and adjustments are minor (1–2°C for 30–60 minutes). You can opt out of any event.
