The easy to move slide allows you to set the temperature between 55 to 90 degrees. The small, thin, and basic design allows for this RV thermostat to blend into any interior.

Bottom Line

Analog thermostats are some of the least popular currently on the market due to their basic design and being a bit old fashioned. However, if there was one thermostat that broke this stereotype, it would be this one.

It may be simple, but this means that it’s easy to use with the simple analog sliding temperature controls. The various features and modes are what make this product so much better than what stereotypes might have you think. Sometimes simple and basic are what win the gadget race.

Bottom Line

These analog RV thermostats are incredibly easy to use and extremely simple; the various features and modes are just as easy to get working. The sliding controls are what make it even easier.

The product blends in well with the background of any RV as it’s a compact product. Unfortunately, these products are known to break and become less effective over time.

Best RV Water Heater Thermostat: Suburban 232306 130-Degree Thermostat


  • Reliable brand
  • Effortless installation
  • Effective temperature regulator

This thermostat is great for regulating the temperature of your hot water. Many times there have been times when hot water can reach fairly unsafe temperatures and have even scalded people with some serious burns because of poor water temperature regulation. This water heater thermostat will allow you to regulate and monitor the temperature safely.

Considering that this is a really basic device that is used just for this one purpose, there isn’t much to mention about it. It comes from a reliable brand and will be able to heat water up to 130 degrees. You also benefit from a really simple installation as it’s such a simple device; there isn’t much to wire up.

Bottom Line

The main benefits of this product are that it comes from a reliable brand and has raving reviews as an effective temperature regulator.

Thanks to the sheer simplicity of this device, the installation process is almost effortless. The appearance of this product leaves much to be desired; it actually looks more like a broken light switch. This has absolutely no impact on its performance, of course.

Best RV Digital Thermostat:
Honeywell TH5110D1006

Best RV Digital Thermostat: Honeywell TH5110D1006


  • Easy to use
  • Dual powered
  • Reliable and accurate
  • 1.5 inch backlit display
  • Heating and cooling system


  • Might take longer to get used to

This RV thermostat is the best digital/programmable thermostat currently on the market for use in your RV. The easy to use and read 1.5 inch display offers plenty of space to have all the information displayed on one screen.

The product allows for you to accurately set the temperature that you feel most comfortable in with one heat and one cooling system. The product is dual powered, as it operates from a battery and from being hardwired into the RV circuit. These products are a lot more reliable and easy to use, thanks to their superb accuracy.

Bottom Line

This product is a lot more modern than the past few thermostats we’ve discussed. The 1.5 inch backlit display will provide you with an accurate reading of everything that’s going on temperature-wise. This monitoring is important so you know that your thermostat is working, making this a huge benefit.

It’s also really easy to use once you get used to all the terms and buttons. It offers a really good heating and cooling system that is dual powered with either battery and hardwired via the RV circuit.

These types of RV thermostats are some of the most reliable and accurate on the market at the moment. As we mentioned, is they might take longer to get used to as they’re digital and not manual.

Best Coleman RV Thermostat:
Coleman Airxcel 8330-3862

Best Coleman RV Thermostat: Coleman Airxcel 8330-3862


  • Easy to use
  • Reliable and accurate
  • Heating and cooling system


  • Small screen
  • Basic digital thermostat

This digital thermostat is part of the Coleman range and is without a doubt the best of that range. This thermostat offers a tiny display that will show you the exact temperature of your RV, which is great for finding that sweet spot or goldilocks zone.

The accuracy is a main attraction for many people; it offers all of the same features, including both heating and cooling modes as well as the speed of the temperature change and whether the fan speed should be high or low.

Bottom Line

This product is quite simple, which makes it easy to use. The controls are similar to that of an analog thermostat. However, the only thing that makes it a digital thermostat is the really small screen in the top corner that displays the temperature reading.

However, this temperature display is a huge advantage, despite the size, as this makes your temperature regulation far more accurate. It offers the same basic stuff like the heating and cooling controls. It is a bit unfortunate that this unit doesn’t offer a larger screen for more information.

Best Programmable RV Thermostat:
Dometic Duo Therm Comfort Control

Best Programmable RV Thermostat: Dometic Duo Therm Comfort Control


  • 12 button display
  • Temperature sensors
  • Large blue light display
  • Modern and sleek design

This truly modern and well-crafted digital thermostat is an easy to read and easy to use product that will work to your pre-arranged temperature, allowing you to sit back and relax. The large SMX blue light display will show you all the information you need to properly regulate your temperature and make your RV really comfortable. You’ll also be happy to know that the installation is also extremely fast and easy.

The built-in sensors will accurately read the temperature of the room in order for them to control and manage the temperature to your standards. You can even heat or cool down up to four different areas of your RV at one time. The 12 button display makes the whole experience more streamlined and comfortable to control as everything is right there for you to mess around with.

Bottom Line

This is one of the best RV thermostats, and offers a more modern and sleek design to that of your standard ugly analog design - a bit of flavor never hurt anyone.

The large blue light display also offers you more information on one screen that lets you monitor and alter the temperature accurately at any time; the same goes for the temperature sensors that will effectively help self-regulate the temperature. The 12 button display also offers more features at only a push of a button.

Bear in mind that if you aren’t used to digital thermostats, they take a long time to get used to, especially something as advanced as this.

Best RV Wi-Fi Thermostat:

Why it Stands Out to Us

This RV thermostat is labeled as the best value for money device. It is simply because it offers a lot of features and reliability within an affordable price. It not only saves a lot of energy but is also very simple and easy to use. Installation is pretty quick, and it is compatible with most HVAC equipment. Besides, it can be controlled via a remote and supports multiple voice commands.

Best RV AC Thermostat:
Dometic RV Air Conditioner Thermostat

Best RV AC Thermostat: Dometic RV Air Conditioner Thermostat


  • Reliable brand
  • Auto fan mode
  • Large LCD display
  • Two year warranty
  • Three different fan speeds


  • This will take a lot longer to understand than an analog

The Dometic brand are market leaders in the RV thermostat industry, which is why it shouldn’t come to you as a surprise that they’ve been featured on this list a few times already. This digital model is fairly convenient for most RV owners as you’ll be able to control the three different fans speeds and air distribution throughout the RV.

The auto fan mode works as a self-regulating system that works to ensure your preferred temperature is acquired. The large LCD display also makes working this product a lot easier and user-friendly than most others on the market. Along with all the many features, you’ll also have a two year warranty that’s included in the deal.

Bottom Line

This thermostat belongs to such a reliable brand that it would be hard to imagine it doesn’t work. The three fan speeds can be adjusted to help evenly spread out the cool air throughout the room. You’ll also benefit from the auto fan mode, which self-regulates the air temperature.

The large LCD display will ultimately help you monitor and understand the information presented to you. It also comes with a two year warranty, which is always a good thing. Like all digital thermostats, this product might initially be a struggle to understand or learn.

Best Duo Therm RV Thermostat Replacement:
Dometic/Duotherm Comfort Control

Best Duo Therm RV Thermostat Replacement: Dometic/Duotherm Comfort Control


  • Smart memory
  • Effective temperature regulation
  • Can recreate four different climate zones at once


  • Might take longer to get used to

This RV thermostat is from the Dometic range and is a great programmable thermostat that will ensure your pre-arranged settings are met as fast as possible. Once within this temperature level, your thermostat will then ensure that the temperature stabilizes at this level.

The smart memory of this thermostat will make sure that during a blackout or powercut your customized settings will be remembered and start back from there. The model also recognizes and is able to recreate four different climate zones within your RV at once.

Bottom Line

This is one of the most advanced RV thermostats currently on the market. It offers a smart memory which will remember all of your customized settings during a powercut and restart with the same settings; that’s something an analog thermostat can’t do. You’ll find after using a digital thermostat that there’s a lot an analog can’t do.

The temperature regulation is also far better as it will ensure that the temperature meets your expectations. Another huge feature is that it can create four separate climate zones at once. The only downside to using digital is that it might take a little longer to get into the swing of things and learn the various controls.

Best RV Comfort ZC Thermostat:
Coleman Thermostat, Digital, Heat/Cool/Heat Pump

Best RV Comfort ZC Thermostat: Coleman Thermostat, Digital, Heat/Cool/Heat Pump


  • User-friendly
  • Accurate
  • Digital display
  • Offers both heating and cooling modes


  • Small screen

This RV thermostat is the best of its range; it offers you a decent-sized digital screen that will display various pieces of information, which makes this product extremely accurate for anyone using it.

This accuracy allows you to effectively monitor and regulate your temperature at any time. The different features of this product are pretty much standard across all thermostats, including the heating and cooling modes as well as the speed and changes in fan speed.

Bottom Line

This thermostat is incredibly simple; the simplicity of these products is what allows people to learn how to use them fairly quickly. The controls are just a few buttons next to a digital display that allows you to monitor whatever is happening and adjust the temperature accurately.

This display is probably the biggest advantage of any digital thermostat as it offers accuracy that no analog thermostat could offer. The two heating and cooling systems are the box standard for any thermostat, an advantage nonetheless. Another benefit is that the box blends in pretty well with any background. Our only gripe is that the screen could be bigger for a more clear view of the temperature controls.

Best 12-Volt Thermostat for RV:
Honeywell RTH111B1016/E1 Digital Thermostat

Best 12-Volt Thermostat for RV: Honeywell RTH111B1016/E1 Digital Thermostat


  • Smart sensors
  • Easy to read display
  • Heating and cool air
  • Smart restart function
  • Auto fan - self regulate
  • Easy to use temperature controls


  • Basic design and features

This 12V thermostat has an easy to read display that provides you with lots of basic information; you’ll receive a breakdown of the temperature at that particular time, which will help you accurately regulate the temperature. The temperature control is fairly easy to understand and can be done fairly accurately by using the two buttons at the side of the display.

You also have the option of both heating and cooling air, as well as an auto fan feature that will self-regulate the temperature around you using smart sensors. If you ever experience a power outage, you’ll have the benefit of having the smart restart function, which will remember your previous customized settings and retain those same settings for when you gain power back.

Bottom Line

For a digital thermostat, you’d expect more features. However, there were a few decent benefits such as the easy to read display and temperature controls that didn’t take much learning before you understand how to work them. The thermostat offers the basic heating and cool air along with a self regulating auto fan mode, this works with the help from internal temperature sensors.

The main attraction here is the smart restart function, which will retain the previous custom setting throughout a power outage and then start from where it left off when you gain back power; this feature is a little more advanced. The main problem with this product is the boring design, there’s no flare to the product exterior. However, it does its job quite well.

Buyer’s Guide

now for the buyer's guide. Here you'll learn all the essential things to know about thermostats. Might sound boring, but it's important to understand what you're buying. We look at the main features of the better thermostats, and why they stand out.

We look at the different types of RV thermostats and compare digital devices to their analog counterparts. We've also included a guide on how to install a thermostat in your RV, so you'll be fully equipped by the time you reach the end.

How to Choose an RV Thermostat

Choosing your thermostat seems like such a trivial task. But in fact, it’s really important. Your thermostat can make your life a living hell if it’s too complicated or just doesn’t offer everything you need. But, how do you know what you need before you need it? The following section will discuss what exactly to look for when thermostat hunting for your RV.

What Features Does it Have?

Thermostats will offer various features that may or may not be beneficial to you as an RV owner. These features include being able to control your thermostat with an app and having a setback feature in case of a power outage; such features might come in handy to one person, but might be unneeded nonsense to someone else. If you like the look of the features, why not give it a shot?


The warranty of your product is important; if the thermostat that you’re about to order doesn’t have a warranty, do not buy it. Not having a warranty means that you’re simply setting yourself up for failure. Thankfully there aren’t many of those out there. However, keep your eyes peeled.


Of course, the most recent reviews of the product are fairly important to look at before buying. Make sure you have a look at different places like Youtube and Amazon reviews as well as blogs like ours before buying. The various types of thermostat are also an important factor as some are really basic and others fairly advanced and new.
