Single Pole vs Double Pole - Which is Better?
When you look at the back of your line voltage thermostat, you will see some wires which are intended to connect it with your heating system. You will see that a line voltage thermostat can have two different wiring configurations - the single pole and double pole. Although both of these thermostats work great in regulating your home temperature, they function in a slightly different way when connected to your heating system.
Single Pole
Single pole thermostats only require two wires to connect to your heating system’s service line. Although it can control your heating system, it cannot completely turn it off when not in use. Thermostats connected in single pole wiring can only turn your heater on the lowest setting to conserve energy.
Double Pole
Unlike single pole thermostats, double pole thermostats have four wires to connect to your primary circuit breaker. This wiring configuration can work on two different circuits and can turn off the power line from either of the circuits. This means that it can act like a switch button so you can turn off your heater when not in use.
So if you’re looking for a smart thermostat that can help you conserve more energy in the long run, then the double pole thermostats work best for you.
How We Choose and Must-Have Features
Line voltage wifi thermostats can be more expensive than the traditional ones. But they offer a lot of features that could be beneficial to your home in the long run.
Choosing the best line voltage wifi thermostats can be daunting, especially if you don’t know what features to look for.
So before you scroll down our list and make a decision, here’s a summary of the must-have features we considered for the best line voltage wifi thermostat:
Energy Efficient
We all want smart devices in our homes for one common reason - to save energy. Smart thermostats provide features that allow you to customize the heating levels in your room to keep you warm and cozy without wasting energy. So when reviewing a line voltage wifi thermostat, consider how much energy savings you can get since not all smart thermostats are made equal.
Scheduling Features
Line voltage wifi thermostats generally work in multi-zone systems so you can control each of your thermostats installed in different rooms. You can change the settings and schedule adjustments in one go instead of adjusting each of the thermostats every time.
Remote Access
Most line voltage wifi thermostats come with an app so that you can access your device right on your mobile phone. Whether you’re still in the office on your way home or on a long vacation, you can adjust and monitor your home climate anytime and anywhere you are.
Zoning Settings
The great thing about having line voltage wifi thermostats is that you can easily regulate the climate in every room with different preferences. This feature can even lower the heating level in rooms that are not used. Zoning provides flexibility and convenience while helping you save on energy cost.
Best for Electric Baseboard Heaters: Mysa WiFi Smart Thermostat
Mysa is your best choice if you want to integrate a voice control. Comes with extensive guides for easier installation!
Customer Reviews
“Finally, the smart device I've been looking for — honestly! Just about every (if not all) other smart thermostats are for heat pumps, HVAC, furnaces, etc — not for baseboard heaters. The design's really simple and elegant — it looks great on the wall. My Mysas were super easy to install and set up, and I've never replaced a thermostat before in my life."
Planning to ditch your old thermostat and switch to a smart line voltage thermostat for the first time? Then you will love the Mysa wifi thermostat for your smart home. It’s easy to install with loads of support online (in case you get lost somewhere) so you don’t need extra help from a professional.
This smart device is enclosed in a sleek and minimalist design so if you’re a little worried about whether the device fits well to your wall decor, then you’ll find Mysa blends well.
A lot of smart home devices like Alexa, Apple HomeKit, and Google Assistant work well with Mysa. The device also works well with IFTTT to cater to your preferred routines. You can even set it on vacation mode to further save on your energy bills. Or activate the geolocation feature to let the device know if you’re home or not and avoid wasting energy in an empty house.
Best for Z-Wave Devices: Stelpro Z-Wave Plus KI STZW402WB+
Stelpro offers compatibility for most z-wave devices. One of the downsides - it doesn't support Alexa.
Customer Reviews
“This thermostat is AWESOME! It's the first 220v thermostat to support z-wave (4/2016). I am using 3 of them with my Nexia system, which supports z-wave devices. For you Nexia users, I think you will be very pleased. I haven't tested it with other z-wave systems, but comments on the Nexia support site indicate that users of other systems are pleased as well.”
Love to integrate your smart thermostat with Z-wave devices? Then look no more - the Stelpro Ki is the only popular Z-wave line voltage thermostat you can find for your home automation system.
It may not come with a lot of fancy features like the other thermostats but it works reliably and follows your commands. So if you love home automation devices, then this simple device could be the best fit.
Aside from the Z-wave, Stelpro Ki is also available in a Zigbee version. Choose whichever protocol will work best with your network.

Customer Reviews
“This is the ideal thermostat to remotely control the electric baseboards in our backyard gazebo. From the inside of our house … we setup the heater temperature of our gazebo … which extends the usage of it late fall an early spring. :-) :-) ”
How many times have you wished your devices could automatically adjust your home temperature the moment your home? When you arrive at your doorstep, just go relax after a long day instead of worrying about manually setting your devices.
The Stelpro ASMC402 can do the job for you thanks to its geofencing feature.
