Smart Thermostats: Are They Worth It (and Which Ones)?

Residential · Commercial · Industrial — Montréal, Laval & North Shore

A smart thermostat can cut your heating bill without you even thinking about it. But in Quebec, there’s a compatibility trap almost nobody knows about. Here’s everything you need to know.

Why it’s worth it

Heating is where it all happens

Heating makes up more than 50 % of the bill in Quebec. A smart thermostat automatically lowers the temperature at night and when you’re away, manages dynamic-pricing peaks, and lets you control everything from your phone. The result: real savings, effortlessly.

What it brings

The real benefits

📉 Automatic setback

Lowers at night and when you leave, warms up before you return. That’s where the savings come from.

📱 Remote control

Adjust each room from your phone, wherever you are. No more cottage heated for nothing.

⚡ Peak management

Pairs perfectly with the Flex D rate: it reduces on its own during peaks.

The Quebec trap

Beware of compatibility

Here’s what sellers forget to mention: most popular smart thermostats (Nest, Ecobee) are designed for low-voltage 24 V systems — perfect for a furnace or central heat pump, but incompatible with Quebec’s electric heating (baseboards and convectors), which runs on 120/240 V line voltage.

For electric baseboards, you need smart thermostats built for 240 V (Quebec brands like Sinopé, Stelpro, Convectair, Ouellet). Choosing the wrong type means a device that won’t work — or worse, a dangerous connection.
Which one to pick

The right model for your heating

  • Baseboards / convectors (240 V): high-voltage smart thermostats (Sinopé, Stelpro, Convectair, Ouellet…).
  • Heat pump / furnace (24 V): Ecobee, Nest and the like.
  • The neutral: some models require a neutral wire in the box — not always present in older installations. We check first.
In practice

Installation, room by room

On electric heating, we generally replace one thermostat per heating zone. Each thermostat handles a maximum power (often up to about 4,000 W depending on the model): a large room with several baseboards may need a thermostat able to drive them, or a suitable setup. Another key detail: some Wi-Fi models require a neutral wire in the box — not always present in older installations. We check all this before choosing the right device.

The features that matter

What makes the difference

Scheduling & geofencing

Automatic setback at night and when away, warming up when you return (detected by your phone).

Peak management

With programs like Hilo from Hydro-Québec, the thermostat reduces on its own during winter peaks — and can earn rewards.

Tracking & alerts

Consumption per room, a freeze alert if heating fails, full remote control.

Good to know

Often eligible for rebates

Smart thermostats are among the efficiency measures encouraged (notably through Hydro-Québec programs). It’s a small investment that pays off quickly — especially combined with a heat pump.

Frequently asked questions

Your questions about smart thermostats

Does a smart thermostat really save money?+

Yes. By automatically lowering heating at night and when away, it cuts the biggest item on your bill, effortlessly.

Do Nest or Ecobee work with electric baseboards?+

No. These models are made for 24 V (furnace, heat pump). For 240 V baseboards or convectors, you need high-voltage thermostats (Sinopé, Stelpro, Convectair, Ouellet…).

Can I install it myself?+

A baseboard thermostat connects to 240 V: an electrician is safer, especially if the model needs a neutral wire absent from older installations.

Are they compatible with the Flex D rate?+

Yes, several manage winter peaks automatically — ideal for saving with dynamic pricing.

Are there rebates?+

Smart thermostats are often among the efficiency measures encouraged by Hydro-Québec, especially in a broader heating project. Check the current program.

How many baseboards can one thermostat control?+

It depends on power: each thermostat has a limit (often up to about 4,000 W). A large room with several baseboards may need a more powerful model or a suitable setup.

Does a smart thermostat need Wi-Fi?+

For remote features and automation, yes. Some also work locally. Note: many Wi-Fi models need a neutral wire, not always present in older boxes.

What is Hydro-Québec’s Hilo program?+

A smart-home service from Hydro-Québec that automatically manages your heating during winter peaks, with rewards for participating.
