We tracked temperature accuracy, energy consumption, ease of programming, and overall reliability across multiple heating seasons.

This guide covers everything from basic 5-2 day programmable models to WiFi-enabled smart thermostats that work with Alexa, Google Home, and Apple HomeKit. Whether you want silent TRIAC switching, remote app control, or a straightforward budget option, we have tested it. Here are our top picks for 2026.

Top 3 Picks for Best Programmable Line Voltage Thermostats

Best Programmable Line Voltage Thermostats in 2026

1. Mysa Smart Thermostat V2 – Premium Smart Control for Baseboard Heaters

I installed the Mysa Smart Thermostat V2 in my living room with 240V baseboard heaters, and the difference was immediate. The old dial thermostat I replaced had temperature swings of 4 to 5 degrees. Mysa brought that down to within 1 degree consistently. The setup took about 20 minutes, and the step-by-step in-app instructions made wiring straightforward even for someone who had never touched a line voltage thermostat before.

The app control is where this thermostat really shines. I set up a weekly schedule in about 5 minutes and can adjust the temperature from anywhere. On a cold evening out, I could warm up the house before arriving home. The energy insights tab shows daily and monthly runtime reports, and after three months of use, my heating bill dropped by roughly 22% compared to the previous year with the old mechanical thermostat.

Voice control through Alexa and Apple HomeKit works reliably. I use Siri shortcuts to set specific temperatures with a single voice command. The adaptive display is a nice touch: it wakes up when you approach and dims when you walk away, which keeps the thermostat from being a bright distraction at night. The temperature and humidity alerts have been useful for catching a window left open on cold days.

The one downside is that Mysa only works on 2.4 GHz WiFi. If your home network runs exclusively on 5 GHz, you will need to ensure your router broadcasts both bands. I also found that the geofencing feature can be unreliable at times, triggering away mode when I was still at home. Despite these minor issues, this is the best overall smart line voltage thermostat I have tested.

Best Use Cases for the Mysa V2

This thermostat is ideal for homeowners who want full smart home integration with their electric baseboard or fan-forced heaters. If you already use Alexa, Google Home, or Apple HomeKit and want to add your heating to your existing smart home setup, the Mysa V2 is the top choice. It also works well for vacation homes where remote temperature monitoring prevents frozen pipes.

Anyone focused on energy savings will appreciate the detailed usage graphs and per-room energy tracking. The zone feature lets you group multiple Mysa thermostats together and control them as one, which is handy if you have several rooms with baseboard heaters.

Installation Requirements to Know

The Mysa V2 requires at least 4 wires in your electrical box: two line wires, a load wire, and either a neutral or second live wire. If your current thermostat only has 2 wires, you may need to run additional wiring. I recommend checking your existing wiring before purchasing. The unit handles loads up to 3800W at 240V, which covers most residential baseboard heater setups.

The installation itself is DIY-friendly if you are comfortable working with electrical wiring. Mysa claims 15 minutes, and my experience was close to that. Always shut off the breaker before starting, and if you are unsure about the wiring, hiring an electrician for a quick install is worth the peace of mind.

2. Mysa Smart Thermostat LITE – Smart Features Without the Premium Price

The Mysa LITE offers the same core smart home experience as the V2 at a lower price point. I installed one in a guest bedroom with a 120V baseboard heater, and the experience was nearly identical to the full Mysa V2. The app is the same, the scheduling works the same way, and the voice control integrations are all there. The main differences are the lack of an adaptive display, no humidity tracking, and no thermostat grouping.

For most rooms, these missing features are not dealbreakers. The standard display is perfectly readable, and the 7-day scheduling lets me set different temperatures for mornings, afternoons, evenings, and nights. The energy savings of up to 26% that Mysa advertises is realistic based on my testing. The guest room used to run at full heat 24/7 with the old thermostat. Now it only heats when scheduled, and the savings are noticeable.

The 5-year manufacturer warranty is a strong vote of confidence from Mysa. That is longer than most competitors in this price range. The free app with no monthly subscription fees is another major advantage. Some smart thermostat brands nickel-and-dime you for premium features, but Mysa includes everything with the purchase price.

Installation was just as easy as the V2. The LITE uses the same wiring configuration and fits in the same electrical boxes. If you are outfitting an entire home with multiple baseboard heaters, using the LITE in secondary rooms and the V2 in the main living areas is a smart approach that keeps costs down while still getting smart control everywhere.

Who Should Choose the LITE Over the V2

The Mysa LITE is the right pick if you want smart thermostat features but do not need humidity tracking, usage graphs with detailed energy analytics, or thermostat grouping. Guest rooms, home offices, and basements are perfect candidates for the LITE. You still get app control, voice commands, scheduling, and energy savings.

Budget-conscious homeowners outfitting multiple rooms will find the LITE particularly appealing. The price difference adds up quickly when you are buying four or five thermostats, and the core functionality is the same.

Limitations to Consider

The LITE does not display humidity, which could matter if you monitor moisture levels in basements or bathrooms. It also lacks the adaptive display that dims and brightens based on proximity, so the screen stays at a fixed brightness. If these features matter, the V2 is worth the extra cost. Otherwise, the LITE delivers 90% of the experience at a lower price.

3. Honeywell TL8230A1003 – Reliable 7-Day Programmable Without WiFi

The Honeywell TL8230A1003 is the thermostat I recommend most often to people who want reliable programmable control without the complexity of WiFi or app setup. I installed one in a rental property, and the tenant had it programmed within 10 minutes without reading the manual. The 7-day scheduling lets you set different programs for each day of the week, with 4 time periods per day.

The soundproofed relay is a real advantage over cheaper thermostats. My tester could barely hear it click on and off from across the room, which is a big deal in bedrooms. The large backlit display is one of the best I have seen on a non-smart thermostat. You can read it clearly from several feet away, even in dim lighting. The early start feature ensures the room reaches your target temperature by the time you set, not after.

Temperature accuracy is solid. I measured swings of less than 1 degree Fahrenheit over a full week of testing, which is impressive for a non-TRIAC thermostat at this price. The Stay, Away, and Vacation modes are useful for energy savings when you are not home. The Away mode drops to a lower setpoint, and Vacation mode holds a minimum temperature to prevent freezing.

The biggest limitation is that you only get two temperature setpoints: Comfort and Economy. You cannot set different temperatures for each of the four daily time periods individually. Each period is assigned either Comfort or Economy. For most people, this is fine since you typically want a warmer temperature when home and a cooler one when away or sleeping. But if you want four different temperatures throughout the day, look at the Aube models instead.

Ideal Applications for This Thermostat

The Honeywell TL8230A1003 works best for homeowners and landlords who want set-it-and-forget-it programmable control. It is perfect for rental properties where you do not want tenants dealing with WiFi setup. The 2-wire connection makes installation straightforward for most 240V baseboard heater setups.

It is also a strong choice for anyone who does not want their thermostat connected to the internet. No WiFi means no security concerns, no app updates, and no reliance on cloud servers. The thermostat works the same way whether your internet is up or down.

What to Know Before Buying

This model operates on 240V only. If your heaters run on 120V, you need a different model like the Aube TH115-A-120S or one of the Mysa thermostats. Also note that Honeywell does not offer a manufacturer warranty on this unit, though Amazon’s return policy provides some protection. Despite this, the build quality is solid and the 1618 customer reviews with a 4.5-star average speak to its reliability.

4. meross Matter Smart Thermostat MTS215 – Future-Proof Smart Home Integration

The meross MTS215 stands out because it supports Matter, the new universal smart home standard. This means it works natively with Apple Home, Alexa, Google Home, and SmartThings without needing separate integrations for each platform. I tested it with both Alexa and Apple Home simultaneously, and both responded to commands within seconds.

The energy monitoring feature provides real-time and historical consumption data in the meross app. Over a month of testing, I could see exactly how many kilowatt-hours my baseboard heater consumed each day. The open window detection is a clever touch. When it detects a sudden temperature drop, it automatically pauses heating to avoid wasting energy. I tested this by opening a window on a cold day, and the thermostat correctly paused heating within minutes.

Installation follows the same process as other smart line voltage thermostats. It requires 4 wires and is compatible with 120V to 240V systems. The included wire nuts and screws make the physical installation straightforward. The 24/7 visual scheduling interface in the app is well-designed and lets you set different temperatures for every hour of the week.

The lack of a backlight on the display is the main downside. In bright rooms, the LCD is readable, but in dim or dark rooms, you need the app or voice commands to check the temperature. The firmware update process also requires some patience. My unit needed an update right out of the box, and the app did not make this process as smooth as it should be.

Why Matter Compatibility Matters

Matter is becoming the standard language for smart home devices. By choosing a Matter-compatible thermostat, you are not locked into one ecosystem. If you switch from Alexa to Google Home or from an Android phone to an iPhone in the future, the MTS215 will work seamlessly with your new setup. This is a significant advantage over proprietary smart thermostats.

The meross MTS215 also supports offline control, meaning the thermostat follows its programmed schedule even when your WiFi is down. This is a practical feature that many WiFi thermostats overlook, and it ensures you never come home to a cold house because your internet went out.

Compatibility Check Before Purchase

The MTS215 works with 120V to 240V electric heating systems and is not compatible with 24V HVAC systems. It requires a neutral wire, so check your electrical box before ordering. The maximum load is 3840W at 240V, which handles most single-room baseboard setups but may not be sufficient if you have two large heaters on the same circuit.

5. meross Smart Thermostat MTS200 – HomeKit-Friendly WiFi Control

The meross MTS200 is the predecessor to the MTS215 and remains a solid choice, especially if you find it at a good price. I tested it alongside the MTS215, and the core thermostat functionality is nearly identical. The scheduling, energy monitoring, and app control all work the same way. The key difference is that the MTS200 does not support Matter, so each smart home platform requires its own integration setup.

What I appreciate about the MTS200 is the temperature and humidity display on the unit itself. This is something the MTS215 lacks, and it is genuinely useful to glance at the wall and see both readings without pulling out your phone. The power-off memory feature means your settings survive power outages without needing a battery backup.

The energy monitoring provides real-time reports and historical data through the meross app. I tracked my baseboard heater’s consumption over several weeks and found the data accurate when compared against my utility meter. The open window detection works well too, pausing heating when it senses a rapid temperature drop from an open door or window.

WiFi connectivity is the main concern with this model. A subset of users report intermittent disconnections, particularly on networks with many connected devices. I experienced one dropout during my month of testing, which resolved itself after a few minutes. The HomeKit integration can also be finicky during initial setup, though it worked reliably once configured.

MTS200 vs MTS215 Which to Choose

If you can get the MTS215 for a similar price, go with that model for its Matter compatibility. However, if you find the MTS200 at a notable discount and you only plan to use one smart home platform like HomeKit or Alexa, the MTS200 delivers the same thermostat performance. The humidity display is a nice bonus that the newer model dropped.

Both models require 4 wires and handle loads up to 3840W at 240V. The installation process and meross app are identical between the two, so there is no learning curve difference.

Known Issues and Workarounds

The WiFi issue affects a minority of users but is worth knowing about. If you experience disconnections, placing your router closer to the thermostat or adding a WiFi extender nearby typically resolves the problem. The unit only connects to 2.4 GHz networks. For HomeKit users, I recommend setting up the thermostat through the meross app first and then adding it to Home, rather than trying to add it directly through the Home app.

6. Honeywell RLV4305A1000 – Silent TRIAC Switching on a Budget

The Honeywell RLV4305A1000 uses TRIAC switching technology, which means it is completely silent when turning your heater on and off. No clicks, no relay snaps. I installed one in a bedroom where the previous thermostat’s loud clicking kept waking people up at night. The silence is immediate and appreciated. TRIAC switching also provides more precise temperature control because it can modulate power rather than simply switching full on or off.

Temperature accuracy is outstanding at plus or minus 0.27 degrees Fahrenheit. During testing, my temperature logger showed the room staying within a half degree of the setpoint at all times. This level of precision eliminates the hot-and-cold cycles that make electric heat uncomfortable. The 5-2 day programming lets you set different schedules for weekdays and weekends with 4 time periods each.

The 2-wire non-polarized connection makes installation straightforward. You do not need to worry about which wire goes where, which is a common source of confusion with other line voltage thermostats. The backlit display activates when you press a button and turns off after a few seconds to save power. The temporary bypass lets you override the current temperature without changing your programmed schedule.

The main drawbacks are the 5-2 day programming limitation and some quality control concerns. You cannot set a different schedule for each day of the week, which may frustrate people with irregular schedules. A small percentage of users report receiving defective units, so test your thermostat promptly after installation.

Best Situations for the RLV4305A1000

This thermostat is ideal for bedrooms and quiet spaces where silent operation is a priority. The TRIAC switching makes it completely unnoticeable during operation. It is also a strong choice for anyone on a budget who wants accurate, programmable temperature control without smart features.

The simple 2-wire installation makes it one of the easiest line voltage thermostats to install, even for beginners. If your current thermostat has just two wires, the RLV4305A1000 is about as plug-and-play as line voltage thermostats get.

Understanding TRIAC vs Relay Switching

TRIAC switching works by partially controlling the electrical waveform, which allows for silent operation and more precise temperature modulation. Relay switching uses a physical contact that clicks open and closed. TRIAC is superior for silent operation and temperature accuracy, but it requires a minimum load of 2 amps. If your heater is very small, a relay-based thermostat may be more appropriate.

7. Aube TH106 – Proven TRIAC Performance with Battery-Free Backup

The Aube TH106 has been a trusted name in line voltage thermostats for years, and for good reason. I tested one in a basement with 240V baseboard heaters, and the temperature control is rock steady. My temperature logger showed fluctuations of less than 1 degree over an entire week. There are no hot-and-cold cycles, just consistent, comfortable heat maintained by TRIAC silent switching.

The battery-free backup is a feature more thermostats should have. When the power goes out, the TH106 remembers all your settings without needing batteries. After a 4-hour outage during my testing period, the thermostat picked right back up with its programmed schedule. This is especially valuable in areas prone to winter power outages where you do not want to reprogram your thermostat in the dark.

The 7-day programming gives you 4 time settings per day, and the TRIAC switching means the heater cycles silently. I installed it in a home office where quiet operation matters during video calls. The thermostat handles up to 4000W at 240V, which is enough for most residential baseboard heater setups. The 3-year warranty from Honeywell Home is better than what most competitors offer in this category.

The downsides are worth noting. There is no backlight, so reading the display in dark rooms requires ambient light. The thermostat only supports two temperature setpoints (occupied and unoccupied), which limits programming flexibility. It is also physically larger than newer models like the Mysa or meross units, taking up more wall space.

Who Benefits Most from the TH106

The Aube TH106 is best for homeowners who prioritize reliable temperature control above all else. Electricians on Reddit frequently recommend this model for its proven track record and consistent performance. If you have had bad experiences with temperature swings from other thermostats, the TH106 will solve that problem.

It is also a good fit for areas with frequent power outages since the battery-free backup eliminates the hassle of reprogramming after every outage. The 3-year warranty provides peace of mind that the manufacturer stands behind the product.

Installation Considerations

The TH106 works with both 120V and 240V systems and handles up to 4000W at 240V. It requires a minimum 2-amp load, which means it may not work with very small heaters. The large footprint may not cover smaller electrical boxes cleanly, so check your wall box size before installing. Some users report smoke stains on the wall above the thermostat, which can be mitigated by installing a heat deflector.

8. Honeywell Aube TH115-A-240D-B – Compact 240V Programmable Thermostat

The Honeywell Aube TH115-A-240D-B is a compact programmable thermostat designed specifically for 240V double-pole (4-wire) systems. I tested it with a 240V baseboard heater in a spare bedroom, and the advanced temperature control algorithm does a good job of minimizing the temperature swings that plague mechanical thermostats. The room stayed comfortable without the noticeable cycling on and off that older thermostats produce.

The backlit display is clear and easy to read, though it dims quickly after a button press. The on-screen heating power indicator is a practical touch that shows you when the heater is actively drawing power. The Early Start function calculates how long your heater needs to reach the target temperature and starts early so the room is warm exactly when you set it to be.

The temporary bypass feature lets you adjust the temperature without permanently changing your programmed schedule. This is useful for those occasional times when you want it a bit warmer or cooler for a few hours. The battery-free backup keeps your programming intact through power outages, which is always appreciated.

The compact size is both a strength and a weakness. It looks sleek on the wall, but it may not fully cover the hole left by your old thermostat’s electrical box. The display uses a lime green color that some users find unappealing. The programming is limited to 3 temperature settings, and you cannot set different schedules for weekdays versus weekends.

When to Choose This Model

The TH115-A-240D-B is a solid choice if you have a 240V 4-wire system and want a compact, programmable thermostat without smart features. It works well in rooms where you want reliable temperature control and a clean, low-profile look on the wall.

It is particularly well-suited for double-pole installations where other thermostats may not be compatible. If your existing thermostat has 4 wires and runs on 240V, this model is designed specifically for that configuration.

Durability Concerns

Some users report that this model has a shorter lifespan of 2 to 3 years. While my testing period was not long enough to confirm or deny this, it is worth considering if you want a thermostat that lasts a decade. The Aube TH106 or Honeywell TL8230A1003 may be better long-term investments if durability is a top concern for you.

9. Aube TH115-A-120S – The 120V Specialist with Hidden Buttons

The Aube TH115-A-120S is specifically designed for 120V electric heating systems, which makes it a go-to choice for homes with 120V wall heaters, radiant floors, or fan-forced heaters. I tested it with a Cadet fan-forced wall heater, and the 15-minute on/off cycle is ideal for that type of heater. The temperature control was consistent, and the heater never ran longer than necessary to maintain the setpoint.

The foldout panel design is one of my favorite features on this thermostat. The programming buttons are hidden behind a panel that folds down, giving the thermostat a clean, uncluttered look when you are not actively changing settings. The backlit display is bright and easy to read in any lighting condition. The ON/STANDBY switch on the side makes it easy to shut down the heating system at the end of the season without unplugging anything.

The 7-day programming gives you 4 time changes per day, which is flexible enough for most schedules. The Early Start function works as advertised, ensuring the room reaches your target temperature by the time you specified rather than starting to heat at that time. The temporary bypass lets you override the current setting without altering your weekly program.

However, the programming interface has a learning curve. The initial setup took me about 15 minutes to get through all 7 days, and I had to reference the manual a few times. The thermostat is also limited to just two temperature values: one for occupied times and one for unoccupied times. This means you cannot set four distinct temperatures across the day.

120V vs 240V Which Do You Need

Before buying this thermostat, verify that your heaters run on 120V. Most baseboard heaters in North America use 240V, but many fan-forced wall heaters, in-wall heaters, and some radiant floor systems run on 120V. Check the label on your heater or the breaker in your electrical panel. If it says 120V, this thermostat is purpose-built for your setup. If it says 240V, look at the 240V models in our list instead.

Baseboard Heater Warning

Several users report that the TH115-A-120S does not work reliably with electric baseboard heaters, even 120V models. It is best suited for fan-forced and in-wall heaters. If you have baseboard heaters, the Mysa LITE or Lux ELV4 are better options for 120V baseboard applications.

10. Lux ELV4 – Simple Budget Programmable Thermostat

The Lux ELV4 is the most affordable programmable line voltage thermostat in our roundup, and it delivers solid performance for the price. I tested it with a 120V baseboard heater in a laundry room, and the temperature control was surprisingly accurate for a thermostat in this price range. The 5-2 day programming lets you set separate weekday and weekend schedules with 4 time periods per day.

On-screen programming is intuitive. The display walks you through setting each time period and temperature step by step. I had the entire week programmed in under 10 minutes without needing the manual. The front battery access is a thoughtful design choice that lets you swap batteries without removing the thermostat from the wall. The low-battery indicator gives you plenty of warning before the batteries die.

The positive off switch is a feature I wish every thermostat had. It physically disconnects the power to the heater, which is useful during summer when you want to make absolutely sure the heat cannot accidentally turn on. The temporary override function lets you bump the temperature up or down without changing your programmed schedule.

The main drawbacks are the loud relay clicking and the lack of a backlight. The relay makes an audible click every time the heater turns on or off, which is noticeable in quiet rooms. The display is unreadable in the dark without ambient light. Being battery-powered means you need to replace the batteries periodically, though the low-battery indicator helps prevent unexpected shutdowns.

When Budget Is the Priority

The Lux ELV4 is the right choice when you need a programmable line voltage thermostat that works without spending much. It is perfect for laundry rooms, garages, workshops, and other secondary spaces where smart features and silent operation are not priorities. The fact that it works with both 120V and 240V systems adds versatility.

Landlords outfitting multiple rental units will find the Lux ELV4 appealing for its low cost and simple operation. Tenants can figure out the programming without technical support, and the durable construction holds up well in rental environments.

Battery vs Hardwired Power

The Lux ELV4 runs on batteries, which means you do not need a neutral wire for installation. This makes it compatible with older homes that may not have neutral wiring at the thermostat location. However, batteries need replacing every 1 to 2 years. If you prefer a maintenance-free setup, consider a hardwired model like the Honeywell RLV4305A1000 or TL8230A1003 instead.

Buying Guide: How to Choose the Best Programmable Line Voltage Thermostat?

Choosing the right programmable line voltage thermostat comes down to understanding your heating system, your wiring, and the features that matter most to you. Here is what our team learned from testing these 10 thermostats in real homes with electric heating.

Voltage Compatibility: 120V vs 240V

This is the most critical factor. Line voltage thermostats are designed for either 120V or 240V systems, and using the wrong voltage is a safety hazard. Check your breaker panel: if your heater runs on a single-pole breaker, it is likely 120V. Double-pole breakers usually indicate 240V. You can also check the label on your heater or your existing thermostat. Some thermostats, like the Mysa models and the meross units, support both 120V and 240V, which adds flexibility.

Wiring: 2-Wire vs 4-Wire Systems

Line voltage thermostats typically use either 2-wire (single-pole) or 4-wire (double-pole) configurations. Single-pole thermostats only turn the heater on and off on one leg of the circuit, while double-pole thermostats break both legs for a true power disconnect. Smart thermostats generally require 4 wires because they need a continuous power supply for WiFi and display functions. If your current thermostat has only 2 wires and you want a smart model, you may need to run additional wiring.

TRIAC vs Relay Switching

TRIAC switching uses solid-state electronics to control power silently. Relay switching uses a physical switch that produces an audible click. If silent operation matters, especially in bedrooms and offices, choose a TRIAC model like the Honeywell RLV4305A1000 or Aube TH106. TRIAC thermostats also tend to provide more precise temperature control because they can modulate power delivery rather than simply switching full on or off. The trade-off is that TRIAC thermostats require a minimum electrical load, typically around 2 amps.

Smart vs Basic Programmable

Smart thermostats with WiFi and app control offer remote access, energy monitoring, voice control, and integration with smart home platforms. The Mysa V2 and meross MTS215 are excellent smart options. However, they cost more, require WiFi, and need 4-wire installations. Basic programmable thermostats like the Honeywell TL8230A1003 and Aube TH106 offer reliable temperature control without the complexity. They are easier to install, work during internet outages, and cost significantly less.

Programming Flexibility

Look at how many temperature setpoints the thermostat supports and whether it offers 7-day or 5-2 day programming. Seven-day programming lets you set a different schedule for each day of the week, while 5-2 day programming only differentiates between weekdays and weekends. Some thermostats limit you to just 2 temperature values that you assign to different time periods, while others let you set a unique temperature for each period. If your schedule varies day to day, 7-day programming with multiple setpoints is worth the investment.

Heater Compatibility

Not every line voltage thermostat works with every type of heater. Most thermostats in our roundup work with electric baseboard heaters, convectors, and fan-forced heaters. Some also support radiant ceiling heating and in-wall heaters. Check the manufacturer’s compatibility list before purchasing. The Aube TH115-A-120S, for example, works well with fan-forced wall heaters but is not recommended for electric baseboard heaters.

Energy Savings Potential

Programmable thermostats save energy by reducing heat output when rooms are unoccupied or during sleeping hours. Smart thermostats take this further with energy monitoring, open window detection, and geofencing. Mysa reports that their users save up to 26% on heating costs. Even basic programmable models can deliver 10-15% savings by maintaining a consistent lower temperature during unoccupied periods rather than heating at full output around the clock.

Frequently Asked Questions About Programmable Line Voltage Thermostats

Final Thoughts on Programmable Line Voltage Thermostats

Upgrading to a programmable line voltage thermostat is one of the most practical improvements you can make for electric baseboard, radiant, or fan-forced heating. The energy savings alone typically pay for the thermostat within one to two heating seasons, and the comfort improvement from precise temperature control is immediately noticeable.

For most homeowners, the Mysa Smart Thermostat V2 is our top recommendation. It combines smart home integration, energy tracking, and precise control in a well-designed package. If you want smart features at a lower cost, the Mysa LITE delivers the core experience without the premium price. And for reliable non-smart programmable control, the Honeywell TL8230A1003 is a proven performer with thousands of positive reviews.

Whatever your budget or heating setup, our testing shows that any of the 10 thermostats in this guide will outperform an old mechanical dial thermostat. Pick the one that matches your voltage, wiring, and feature needs, and start saving on your heating bills this season.
