No hub. No C-wire. Just smarter, simpler warmth.
1. Why Your Baseboard Heater Needs a Smarter Thermostat in 2025
Still adjusting a manual dial on your electric baseboard heater? You're not alone. Millions of homes across the U.S. and Canada—from vintage apartments to mountain cabins—still rely on baseboard heating. It’s simple, quiet, and effective. But without a smart thermostat, it’s also outdated.
Unfortunately, not all smart thermostats are compatible with 120V or 240V baseboard systems. Many homeowners buy popular options like Nest or Ecobee—only to discover they don’t work.
This guide will show you what does work in 2025, and why the Grus EcoNet-BH smart thermostat stands out as one of the most compatible and convenient options on the market today.
2. Why Most Smart Thermostats Don’t Work With Baseboard Heaters
The main reason? Voltage.
Baseboard heaters operate on line voltage (120V or 240V), But the most popular smart thermostats are designed for low-voltage (24V) HVAC systems(see official compatibility here). Models like Nest and Ecobee simply don’t work with baseboard heat. Trying to force compatibility could damage your wiring—or worse.
This difference makes them incompatible. Most smart thermostats also require a C-wire (common wire) for power(see what C-wire is and why you need), which is typically absent in baseboard setups.
In short: you need a smart thermostat made for high-voltage systems.

📌 FAQ: Smart Thermostats & Baseboard Heating
Q1: Do smart thermostats work with electric baseboard heaters?
A: Not all of them. Most popular smart thermostats are made for low-voltage (24V) systems and don’t support high-voltage (120V/240V) electric baseboard heaters. To control baseboard heating, you need a line-voltage compatible thermostat.
Q2: Can a Google Nest thermostat work with electric baseboard heaters?
A: No, the Nest thermostat is not compatible with line-voltage electric baseboard heaters. Nest is designed for central HVAC systems, and using it with baseboard heaters could be unsafe or simply not function.
Q3: What type of thermostat is typically used with electric baseboard heaters?
A: Line-voltage thermostats rated for 120V or 240V are used with electric baseboard heaters. These thermostats directly switch the power on and off to the heater, unlike low-voltage thermostats which control signals to a central unit.
Q4: Can I use one thermostat for multiple rooms?
A: You'll need one per zone. But with app control, you can manage all zones in one place.
Final Thoughts: Upgrade the Right Way
Baseboard heaters still have their place—but your thermostat doesn’t have to stay in the 90s. Whether you’re managing a rental, caring for family, or just want to lower your bills, a smart thermostat designed for electric baseboard systems can make all the difference.
✅ Compatible.
