If you’re searching for the best smart thermostat for electric baseboard heaters, you’ve probably run into the same problem thousands of homeowners face every year:
Most smart thermostats — including popular models like Nest and Ecobee — do not work with 120V or 240V electric baseboard heat.
So people buy the wrong thermostat, return it, search again, and get stuck in a loop of questions like:
- “Which thermostats actually work with baseboard heaters?”
- “What is the best thermostat for electric baseboard heat in 2025?”
- “Is there a wireless thermostat for electric baseboard heaters that’s not $200+?”
This guide gives you clear, real, up-to-date answers.
In 2025, several smart thermostat brands finally offer reliable line-voltage options. Among them, the EcoNet-BH stands out with full 120V/240V compatibility, wireless app control, and the best value.
Choosing a Smart Thermostat for Electric Baseboard Heaters in 2025
Why Most Smart Thermostats Don’t Work With Baseboard Heat
Electric baseboard heaters run on line voltage (120V or 240V).
But almost every mainstream smart thermostat (Nest, Ecobee, Honeywell, etc.) is designed for low-voltage (24V) HVAC systems.
Connecting a 24V thermostat to a 240V heater is unsafe and will not work.
That’s why you must choose a line-voltage smart thermostat specifically built for baseboard heat.
120V vs 240V — Why Compatibility Matters
Most North American homes use:
- 120V for smaller rooms
- 240V for large or multi-baseboard zones
Your thermostat must match your system’s voltage.

Read the Smart Thermostat Heating Guide →FAQ: Smart Thermostats & Baseboard Heating
Do smart thermostats work with electric baseboard heaters?
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.
Can a Google Nest thermostat work with electric baseboard heaters?
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.
What type of thermostat is typically used with electric baseboard heaters?
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.
Can I use one thermostat for multiple rooms?
You'll need one per zone. But with app control, you can manage all zones in one place.
Is there a wireless thermostat for electric baseboard heaters?
Yes. EcoNet-BH, Mysa, and Sinope all offer WiFi smart control.
Final Recommendation
If you want a thermostat that is:
✅ Compatible with 120V/240V
✅ Smart, wireless, app-controlled
✅ Easy to install
✅ Affordable
