If you love to camp in winter weather conditions, it can mean amazing travel opportunities for you. Beautiful cold climates, fewer tourists around, and you can see it all from the comfort of your RV!

However, what happens when your freshwater tank freezes due to these cold climates? Can anything be done to prevent your RV’s precious liquids from freezing? Thankfully, there is a product out there for you: RV tank heaters.

RV tank heaters are a wonderful invention and something that may come standard on newer RVs. But what are they, and are they right for you? Let’s take a look, and go over some of the best tank heaters for your RV!

But if you want to skip ahead and just see what made the list you can check out our favorites here:

What Are RV Tank Heaters?

RV tank heaters, also known as RV tank heating pads or RV holding tank heaters, are exactly what they sound like. They are heaters, usually found as pads, that attach to your various RV holding tanks.

These tank heaters run off of your RV’s existing power, either using the AC shore power or the battery-operated DC power. There are tank heaters designed to use either energy source, depending on your preferences, and sometimes the heaters have dual power options.

These tank heaters may sound complicated to install, given their need for electric power. However, they may be easier to install than you think, especially with helpful youtube tutorials like the one below!

 While RV heating pads mainly exist to be installed on the outside of your holding tanks, you can purchase smaller heating pads as well. Often angled or manufactured in various shapes and sizes, these heaters are more versatile. 

The pads attach to various pipes and fixtures, which means you don’t have to worry about water or fluids freezing up in any areas of concern. They are also very similar to the larger pads in terms of installation.

RV tank heaters are often installed standard or as a relatively common add-on to new RVs. Given the popularity of RV travel year-round, more and more manufacturers are considering tank heaters a necessity.

However, if you don’t own a new RV, tank heaters are an easy after-market installation. They can be incredibly useful for full-timers in cold climates, or anyone worried about getting caught in the snow for a few days!

When Do I Need RV Tank Heaters?

While there are other options to keep your tanks from freezing, there are times when you need RV tank heaters. If you are planning to camp in your rig during freezing temperatures for more than one night, RV heating pads are an excellent solution and a necessity for many RV owners.

Most RVers recommend using tank heating pads when the outside temperature reaches 32 degrees Fahrenheit or below, especially for extended periods. However, you can only use RV tank heating pads when you have liquid in your various tanks.

The pads are made to prevent the fluids and liquids in your various tanks from freezing, leading to expanding and cracking of your tank. However, if you turn your tank heater on when there is no liquid present, you may cause just as much damage to your tanks as if you had just let it freeze!

Some RV tank heaters have thermostats and can automatically detect when it is time to turn on. This can be the most convenient, though expensive, option for those of you shopping for aftermarket heating options.

You can always use RV antifreeze for your pipes and tanks, though these products are best for a rig that is left sitting for the winter. However, you may wish to check out some of these products if RV holding tank pads are out of your budget. 

Overall, you should plan on a way to heat your RV’s tanks if you are traveling in winter weather conditions, even if there isn’t a snowstorm coming. Ambient freezing temperatures can quickly freeze your RV’s various systems, which means more damage and money spent in the long run! 

Types of RV Tank Heaters

Most RV tank heaters can be found in pad form with easy-to-install instructions. However, there are many types of specifications for RV tank heaters, as well as various sizes and purposes. Let’s check out the different types.

Standard Pad Heater (AC or DC)

The most common type of RV tank heater comes in a heating pad form, complete with easy-to-install, peel-and-stick adhesive. These pads will fasten to the underside of your holding tanks and allow you to hook them up to your existing RV power system.

These pads come in various energy consumption amounts as well as sizes. They are also available in AC shore power or DC battery power options, and sometimes both power options are available. The AC power heating pads are usually more expensive than their DC counterparts. However, AC-powered heaters usually use fewer amps, which could be an important distinction to make when you are budgeting.

These pads range in price depending on their manufacturer, but certainly because of their various tank heating sizes. The bigger the tank, the more expensive it will be to heat. However, RV tank heating pad manufacturers are aware of this and usually scale their pads to appropriate sizes.

The amperage draw ranges from 1 amp to as many as 12 amps, depending on the size of the heater. Calculating your amperage is important when it comes to maintaining your RV during your camping trip, so keep your newly installed tank heaters in mind. 

If you plan on boondocking and relying on your RV’s batteries during this time, your heating pad may drain your batteries faster than you think! However, having tanks that aren’t frozen is definitely a huge benefit.

Pipe and Pipe Elbow Heaters

If you have a newer RV with tank heaters installed, you may be wondering if there is anything more you can do to further protect your new rig. You’re in luck! Besides using nontoxic antifreeze, you can buy heaters for your pipes and the elbows of your pipes.

These little heaters operate almost identically to your large tank pad heaters, except they are much smaller. Drawing very few amps, these tiny heaters can adhere to your RV’s various pipes and fixtures. There are specialty pipe elbow heaters for any tricky pipe corners that may be present in your rig.

These pads still have to be integrated into your RV’s electrical system, but it may be something to consider should you not need an entire tank pad heater at this time. Given their small size and minimal amperage draw (usually less than 3 amps per heater), these little guys are primarily made for DC battery power. This could be a pro or con, depending on your intended usage and travel plans.

These pads may work perfectly if your holding tank heating pads are currently on your AC system. That way, your batteries aren’t taking the brunt of the amperage necessary to keep these heaters running!

Gate Valve Heaters

Even more specific than pipe or elbow pipe heaters, there are also pad heaters specifically made for your RV’s sewer valve! Gate valve heaters are used when the valve is frozen closed and you’re trying to vacate your black and gray water systems.

You may not ever consider this heater as a necessary component. However, imagine this scenario: it’s extremely cold and windy outside and you stop by the dump station to vacate your black and gray holding tanks like your rig’s manufacturer recommends. You pull one of the dump lever handles and it won’t move; this means your RV dump valve is frozen!  

This can mean a really tough time for some RVers who often camp in cold climates. While a frozen valve may not happen very often, it is certainly something that cold-weather campers encounter. That’s why there are heating pads made specifically for sewer valves too. The heat panels used in gate valve heaters are designed a bit differently than your holding tank heaters.

These little valve heaters are made to rapidly penetrate the thicker plastic with enough heat to thaw the frozen tracks of the gate valve, fast! Sounds cool, right? There are a few caveats to this, such as the RV gate valve heater must be controlled independently from all the other heaters, with a separate on/off switch just for the gate valve option. This switch is usually located near the valve itself.

If needed, turn the heater on for approximately 5 to 7 minutes, or until the valve is freed.  Turn off the switch and evacuate the tanks as you normally would.  These heat panels are designed for short-term use, and only in freezing cold weather where the gate valve has been frozen closed.

What To Consider Before Purchasing An RV Tank Heater?

Before you decide on your favorite RV holding tank heating pads, there are a few additional things to consider. Check out these key facts before we dive into our list of products.

How The Heater Will Be Powered

We’ve touched on this a bit already, but a key consideration for you to make is how you would like your RV tank heater to be powered. Choosing after-market heating pads is often better than having pads already installed, as you can choose the power source that works best for you!

Your holding tank pads can be powered by either DC or AC power. They can rarely be powered by both, so this means that the power option you choose matters. If you are planning to be hooked up to shore power for most of your trip, then AC is the best way to go.

However, if you are hoping to boondock in the winter, you will want a tank heater independent of any shore power. DC power will be your best bet, though you will need to keep in mind how many batteries you have aboard your RV and how many amps they can handle.

Choosing DC-powered heating pads may be beneficial for those of you hooked up to AC power for this reason: your RV no doubt needs the majority of your AC power for various appliances. So it could be beneficial to have your heating pads hooked up to your battery power so that you always know your AC amperage draw. No one likes a blown fuse!

The Size Of Your Holding Tanks

You will soon discover that the size of your RV’s holding tanks is one of the main factors when it comes to choosing a tank heater. Most tank heating pads are classified and sold based on the size of the tank that they are capable of heating.

So, knowing the size in gallons of your current holding tanks is necessary! Hopefully, you know this number or can contact a manufacturer to ask what size your tanks are. But, if you’re like me and don’t know how big your tanks are, this step can feel a bit daunting. 

Most RV holding tanks have their capacities written on the outside, which means that if you aren’t sure of your capacities, the tank should hold the answer! Otherwise, especially for older or less known RV manufacturers, check out some forums or RV experts for more information.

Knowing your tank size is detrimental to purchasing a properly sized tank heater. You don’t want a heater that is far too large (which could overheat your tank) or much too small (which could leave your tank partially frozen).

The Weather For Your Upcoming Trip

Camping in the snow or other wintery weather can be a magical experience! However, it is important to be prepared for camping trips such as these. Before you purchase your tank heaters, knowing where you plan on traveling will benefit you.

Are you planning on visiting a location that has forecasted temperatures of around 35 degrees Fahrenheit? You may need to worry a bit less about having holding tank heaters. However, is your forecast looking a bit chillier than that?

If your trip is scheduled during freezing temperatures, tank heating pads could make the difference between a fun experience and a miserable trip. Keep in mind where you are traveling to and that location’s winter weather before you make your final tank heater purchases.

Budget

Your budget for your RV’s tank heaters is important. While there aren’t too many products on the market so your average cost will be almost the same no matter what, there are certain factors that help with saving some funds.

For example, choosing tank heaters that run on DC power rather than AC power is occasionally less expensive. Plus, choosing the right size to fit your tanks could help you save a few bucks when you would otherwise buy a heating pad that’s too large for your rig!

While it does vary depending on the size of your tanks and the number of pads needed, the average budget for purchasing RV holding tank heaters ranges from $100-$500. It all depends on how many pads you anticipate needing and what power option you are hoping for, as well as the potential installation fees should you not be installing these yourself.

How Many Tanks You Want Heated

There are three primary tanks of liquid found on RVs: your gray water tank, your black water tank, and your fresh water tank. While the locations of these tanks vary, if you plan to camp in cold weather it is recommended that all of these tanks are heated.

While this may not be ideal for your budget, the last thing you need is for any of these tanks to split or crack. However, I know that my fresh water holding tank is located inside the shell of my rig, which means it is no doubt warmed by my own personal heater! I would not need to purchase a fresh water tank heater, at least not right away.

Most black and gray waste water tanks are found underneath your rig and, unless you have an insulated underbelly, you may want to purchase a heating pad for both of these tanks. Some rigs have the black and gray waste gathered into one tank, so that means you would not have to purchase as many pads.

No matter what, a good rule of thumb is this: if you’re planning to heat one tank, you may as well heat them all! If you’re going somewhere cold enough to merit tank heaters, then you best make sure they are all heated properly.

If You Want A Power Switch Inside Your RV

While all RV holding tank heaters are designed to sense the inner temperatures of your tanks, they can’t turn on without you! Having a power switch for your tank heaters is a great option for many reasons.

It could be beneficial to have a switch for your tank heaters inside of your RV should you be camping in cold weather. Could you imagine going outside to manually turn on your tank heaters in a freezing winter storm!? Brr!

However, these switches are not always standard, and it may cost a bit extra to get one, especially one with three distinct switches for each tank heater. Plus, a switch may mean a more complicated electrical installation, something you may not want to do yourself.

If you are having your tank heaters installed professionally, a switch may be something you request. If your budget can handle it, a switch for your tank heaters may be the most convenient and ideal option for you!

The Best Tank Heaters For Your RV

Feeling confident about all of this information regarding RV tank heaters? Do you know what sizes your tanks are and how big of a pad you need? Are you planning to install these yourself, or will you be seeking professional installation help?

I’m sure you’ve answered all of these necessary questions, so let’s get down to the list of the best tank heaters for your RV!

Best Overall: Facon 8.0″ x 25″ RV Tank Heater Pad

I’ve included the name Facon a few times on this list, as it’s a brand that makes reliable and easy-to-install tank heaters, perfect for many different-sized tanks, and every level of RVer, even beginners. This one, in particular, is ideal for tanks up to 50 gallons in size, so I know my hefty tanks are covered for when temperatures plummet. 

The built-in sensor in the heater will turn “ON” the tank heater as soon as the tank temperature drops to 45°F( + – 5 degrees), this is an impressive feature in my eyes, as it takes a job off my plate and does the hard work for me – turning on when needed. From the get-go, the tank heater immediately starts protecting my holding tank from freezing up, and what’s even better, is that when the temperature in the holding tank rises to 68°F( + – 5 degrees), the tank heater will automatically turn “ OFF”.

The pad size of 8.0” x 25” works efficiently on up to 50-gallon holding tanks, whether it be a freshwater tank, grey water tank, or black water tank, making this suitable for a range of RVers. I like this 3mm foam insulation pad as it is self-adhesive, making it easy to install, with no extra fuss or adhesive required.

Using AC power, the heating pad uses low amps, whilst heating my tanks efficiently. This is a game-changer for me, as I don’t have the biggest electrical set-up in my rig and can’t use appliances or kit that needs a high volume of power. I also enjoy that these heating pads can be bought in packs of three, so I can have ideal cold-weather coverage for all three of my holding tanks!

While this heater takes our best overall slot on this list, it is important to note that the manufacturer doesn’t recommend installing this unit on the same circuit as a pump motor or microwave oven. This may be a bit frustrating if you’ve already planned where you were going to install the heater, but with some re-jigging and brainstorming, it won’t be too hard to sort it out.

Best DC Power Option: Facon 12″ x 18″ RV Holding Tank Heater Pad

As I already mentioned, Facon is going to be on this list once or twice! This particular heater pad is also built for 50-gallon holding tanks, but it is made to be installed using your DC or battery power system, not your AC, which may be more beneficial for some.

This heating pad passed the US Standard QAI Quality Certification, which means it is a reliable and safe product, something important for my partner and me as we only want safe, durable products in your rig. Facon also takes full responsibility for their products and customer dissatisfaction, offering a reliable customer service line and a one-year warranty on this heater, giving me the peace of mind I need that if I face an issue, I have somebody to help for some help and advice.

Other than that, the specifications on this model are similar to the last product listed, save for the size of the pad and that it runs on DC instead of AC power. For tanks larger than 50 gallons, I would advise purchasing additional pads as the goal is to heat the tanks fully, stopping them from freezing. 

The built-in sensor in the heater will turn “ON” the tank heater as soon as the tank temperature drops to 45°F( + – 5 degrees). The tank heater immediately starts protecting your holding tank from freezing up. When the temperature in the holding tank rises to 68°F( + – 5 degrees), the tank heater will automatically turn “ OFF”. This heater is therefore easy to use and is an effective way of protecting my tanks from the cold.

I would recommend being fully certain the pads are charged up by using a multimeter or similar, and that they fit your tanks perfectly before taking off the backing paper and installing them. Trying to take the pads off once they’re stuck on is a nightmare and a sticky mess, so it’s best to be sure and check beforehand.

Best Dual Power Option: JR Products HTH-A Holder Tank Heater

I said that a dual-power RV tank heater was rare, not impossible. That’s why I’ve added this heater from JR Products to our list. It’s an innovative, dual-tank heater able to keep up with the rest of the dual energy option appliances in my RV!

Winterizing my RV is a crucial part of protecting my rig from low temperatures, and this tank heater is an extra layer of protection. This is a simple way to start preparing your RV for the winter season. I like that it’s conveniently dual-voltage-ready for 12V or 110V, and is thermostatically controlled at 34 degrees, as discussed in the video below.

As you can see, this pad only uses 1 amp while on AC power and 10 amps while on DC power, making it a great fit for heating my holding tanks. I know I’m covered when the cold weather hits as it’s designed to fit tanks up to 15 gallons. If you have a larger RV with big tanks, I’d recommended purchasing a tank heater that’s on the bigger side to make sure the tanks are adequately protected. 

Easy installation is something I always look for when browsing RV products, but this tank heater isn’t as easy as it sounds! The adhesive isn’t the stickiest which can make things tricky, so I would advise adding some more after installation to help keep everything secure and attached.  

Overall, however, this heater is created by the family-owned and operated JR Products, and since I try to buy and support local where I can, this is a tank heater worth considering. The product lineup for JR Products includes everything from Hardware to Electrical, Plumbing to LP Gas, and so much more, so they are a reliable company in the RVing game that knows the importance of high-quality and effective RV products.

Best Whole Kit With Switches: RV Tank Heater Pad Kit 12V | Includes Toggle Switch and Wire by RecPro

Although I’m happy to take step-by-step measures to support my RV through cold temperatures, I find that all-in-one kits can be a game-changer, saving me time and effort when protecting my rig’s tanks. So, that’s why I’ve included this spread by RecPro! It includes 3 pipe elbow pads, 3 tank heater pads up to 50 gallons each, 60 ft of wire for proper installation, and a triple toggle switch – everything I need for a safe and durable RV tank water heater set-up. 

Both the tank heater pads and the elbow heater pads are specifically designed to insulate and heat my tanks and pipe elbows, respectively. I like that this heating pad has been used by RV owners for years, as it means I trust this product to keep my tanks warm and protect water safety down to -11° F. Something that can affect how well the heater works is poor installation, so I feel it’s best to take your time and make sure as much of the tank is covered correctly as possible. 

The tank heater pad measures 12” W by 18” L and the elbow heater pad measures 13” L by 3” W, and both pads are 3.0 mm thick and are rated for a DC connection. These specifications make this heating pad suitable for a range of RV types and designs, coving fresh, grey, and black water tanks up to 50 gallons, and even includes a 36” lead wire. The elbow heater pads are to be used with 3” elbow pipes and come with an 18” lead wire.

Like the other heaters mentioned on this list, I enjoy the automatic sensors as they know when it’s time to turn on and off, saving me a job, but the elbow heater pads don’t have this ability. Because of this, I find the toggle switch easy to use and read, with a clearly defined label on it as well as an LED light built into the switch, allowing me to see whether the heater pads are on even in the middle of the night.

Best For Large Tanks: UltraHeat 75 Gallon RV Tank Heater

UltraHeat is known as the original and #1 selling anti-freeze protection brand of products for RV and marine holding tanks and drainage systems, first introduced in 1988. This brand has been the RV industry standard to use since 1991, so there’s no doubt in my mind that this large-capacity heater will tick the boxes for an effective tank heater.

Archived as an “Industry Changing Product” in the RV Hall of Fame back in 2011, this tank heater has been copied but never beaten in performance or longevity. Reportedly, heat panels originally installed back in the early 90s are still satisfactorily working today, which means I most certainly trust this brand’s reliability.

UltraHeat products use exclusive UltraHeat Technology and have been designed and used by everyday RVers to effectively perform in temperatures down to and even below -11°F (-23.9°C). This does depend on RV designs, installation modifications, and add-ons, but generally, I trust this piece of kit to protect my tanks during winter. It’s recommended by seasoned RVers for use in everything from mildly cold weather to the most extreme and unfriendly climates and is a good addition to make to your winterizing routine.

All Tank Heater models have a built-in sensor to maintain holding tank fluid contents between 44°F (7°C) and 64°F (18°C) once power is supplied, meaning there’s no need for me to monitor the temperatures as the heater is doing the job for me! This particular model is built for tanks up to 75 gallons which is a bit too big for my tank but might be perfect for those with bigger rigs. 

Tank heaters, in general, can be quite an investment, so I think it’s wise to take the installation slow and get it right the first time. The last thing you want to see when driving down the road on your family vacation is heater pads flying in the wind behind your RV! So ensure everything is stuck down and secure before setting off on a new adventure.

Best For Your Pipes: Facon 3″ x 8″ RV Elbow Pipe Heater Pad

Yep, you guessed it. It’s Facon branded heating pads again! This time, they’ve made smaller-sized heaters, built specifically for RV and elbow pipes. I like the flexibility of buying these little guys in a pack of two, three, or six, as it gives me plenty of options to fully heat all of my RV’s exposed tanks and pipes!

These heating pads measure three inches by 8 inches, small enough to cover any pipe elbows or straight piping, which is essential for RVers like me who travel year-round and often face all four seasons from scorching summers to icy winters. It’s ideal for pipes that measure an inch and a half in diameter, which is good as this is a fairly standard unit of RV pipe measurement. They use about half an amp of DC power each, which means I hardly notice their energy draw, and my batteries don’t struggle.

The main downside of these heaters is that they only really have an on or off mode. However, the low level of heat that they give off will protect my pipes well during harsh winter conditions. Since they are not thermostatically controlled, it is important to only use them during cold months, so this is something worth remembering if you chose to purchase this elbow pip heater pad.

Best On A Budget: RV Holding Tank Heater Pad by H&G Lifestyles

RVing can cost a substantial amount, so I tend to look for RV products that won’t break the bank! This two-pack of heaters by H&G Lifestyles gives me two for the price of another company’s one and still has many similar benefits. 

H&G Lifestyles heater pads are designed to protect RV water tanks from freezing, and with this pad providing protection against ambient temperatures down to -20 degrees Fahrenheit, I know my rig and its components are covered. This heater keeps the inside water temperature well above freezing, so I can rest easy knowing the water on board won’t freeze. Using reliable AC power to do so, this pad has a low amp draw as well, something I like as I love to camp off-grid, and this means limiting my power usage.

Built for tanks up to 50 gallons, this two-pack should have most winter weather needs covered, but I would advise a bigger heater if you have larger tanks sized more towards 70 gallons. The standard power plugs are a perk in my eyes, but this depends on what you are looking for and your specific RV setup. Installing the pads with DC power might be an option, so it’s worth doing some additional research for your specific setup. 

Along with maintaining a reliable temperature inside my holding tanks, these heaters come with a 2-year warranty. This should protect my purchase and allow my pads to be replaced should anything happen to them. No matter the price or budget, having reliable customer service is essential for me!

Installing Tank Heaters

While RV holding tanks and pipe heaters require some finesse to install, it is not impossible for the average DIY-er to do! However, since you will need to alter your RV’s electrical system with this installation, it may be something you’d prefer a professional to do.

If you’re up for the task, installing an RV tank heater is easier than you might think! Besides following helpful youtube tutorials, here is an easy guide to installing your new heating pad.

1. Determine Where To Install The Pad

Many manufacturers have specific installation instructions for your new heating pad, but most companies suggest installing the heat panel as close to the drain outlet of a holding tank as possible, and with the power wires running towards the outlet.

2. Clean The Exterior Of The Holding Tanks

Wherever the pad adhesive will be touching, make sure you clean the area thoroughly. A simple soap and water mix usually does the trick. Once everything is squeaky-clean, you can go ahead and peel away any paper backing from the adhesive. Be careful that the adhesive does not catch on anything, as it is usually very powerful!

3. Press Adhesive Side Onto Tank

Begin pressing the adhesive side of the pad onto your RV holding tank. Begin at one end and slowly press the rest of the pad onto your tank, one end to the other. Be sure to apply an even amount of pressure to all adhesive sections of the pad. This step is important to ensure an even and secure fit on any and all RV tank heaters.

4. Attach All Electrical Elements

While your battery and RV aren’t hooked up to electricity, attach your heating pad’s power wires to your existing power wires. This is the trickiest part of this installation, and do consider seeking professional installation help should you be nervous about this.

Pipe and valve heaters are installed in the same way, though finding your necessary electrical components may be a bit more difficult. However, any RV repair shop should be able to install these for you with little issues, and you may consider this option if you have not done many RV repairs yet yourself.

Maintaining RV Tank Heaters

Your RV tank heaters are easy to maintain, as they are meant to be installed and forgotten. However, you may wish to maintain them in the following ways. Just like every part of RVing, some maintenance is necessary!

1. Clean and Check RV Heating Pads Regularly

The underside of your RV sees a lot of dirt and grime, especially snow in the winter months! These pads are designed to be waterproof, so cleaning them should be a fairly easy task. It’s also essential to check your RV heating pad insulation for any wear and tear. This easy maintenance may be something you want to do after every trip, just to ensure no wayward rock or road debris has damaged your heaters.

2. Install RV Underbelly Protection

The best option for long-term protection of your RV tank heating pads is to install RV underbelly protection or insulation. A single sheet of corrugated plastic could be all you need to ensure a long life for your heating pads!

3. Ensure Electrical Connections Aren’t Worn

While a bit of electrical tape can work in a pinch, you shouldn’t be taping up your RV heating pad electrical connections. This can be dangerous in the long run, and maintaining your electrical wiring is key to these heaters lasting a while.

4. Check Pads Are Off During Summer

Make sure your heating pads are off during warmer months and when your tanks don’t have liquid present. You don’t want to burn out your heater while you don’t need it, and you certainly don’t want to damage your tanks when there’s no water inside of them!

Conclusion

Choosing a tank heater suitable for your RV tanks is a crucial part of preparing to camp during inclement weather. If you’re a dedicated cold-weather camper, RV holding tank heaters are great purchases to make, as they will ensure your fresh water, grey waste, and septic tanks won’t freeze when temperatures drop below zero.

You simply have to turn them on, and then enjoy defrosted holding tanks, no matter how cold it gets outside!
