  • Safety for Heating Elements (CSA) C22.2 No. 72-m1984 (R2004)
  • Flammability tests (UL) 746C, 15 and CSA 0.17,9,2
  • Dieletric Voltage Withstand Test (UL) - 1000 volts/1 minute

Note: This heater pad should be installed on non-conductive surfaces only.


Why ThermaHeat?

When the outside temperature is cold enough, the exposed freshwater holding tank or step on your RV will freeze. For tanks, this stops the flow of water from reaching your sink, shower, or other freshwater source. Furthermore, the frozen water could potentially cause cracks or other irreparable damage to your tank or pipes, which would mean you would have to replace them. And a frozen step can be extremely slippery as you try to enter or exit your RV or camper.


The full-contact ThermaHeat heater pad will prevent this by keeping your holding tank or step warm during freezing temperatures. It has a built-in thermostat that automatically operates the pad. When the temperature of the tank or step drops to 45 degrees F, the pad will turn on. When the temperature rises to 67 degrees F, the pad will turn off. It can also completely thaw out a tank or a step if it's already frozen, assuming that none of the components have been damaged. The heater pad does all the work for you, preventing you from having to go out in the cold and thaw it out by hand with a heat gun or hair dryer, which can melt the side of your tank or step if not used properly.


Installation and Wiring

ThermaHeat Peel-and-Stock Installation

This heater pad has easy, peel-and-stick installation onto the bottom of your tank or step. The flexible carbon fiber material is designed to fit the contours of any surface. The pad is meant for use on fresh water tanks, but can be installed onto gray water or black water tanks. Please note, however, that adding a heat source to a gray water or black water tank may create excess gasses and odors.


ThermaHeat 2-Wire Design

The pad has a white wire for ground, and a red wire for power. This 2-wire design is compatible with DC power while your RV is in transit. It can also run through a converter while connected to a power source when your RV is parked.


Additionally, you are able to install this pad with other ThermaHeat heater pads (sold separately). In order to do this, they must be connected and run parallel. You would daisy-chain the red wires together and connect them to the battery of your RV or camper and then daisy-chain the white wires together and ground them. In order to turn the pads on and off, you will need to install a switch (sold separately) between the battery and the pads.

by:

Holding tank heater pad sort of mounted, but as of now, have had no need to use.



by:

1 year later, still solidly adhered to the bottom of the plastic freshwater tank.



by:

Packaging fail but customer services made it right in a quick and efficient manner!



by:

I am very pleased with these tank heaters and the excellent customer service provided by etrailer! I installed one on each of my 3 tanks...fresh water, gray water, and black water. Easy peel-and-stick installation! Then I routed the wires thru split loom wire sleeves and secured with zip ties. I'm ready for freezing weather now.



by:

Heater pad was delivered in excellent condition. Mounting it to my 30 gallon, exposed gray tank was simple. The adhesive is very strong and aggressive, so be careful with initial placement. Of course as always, I thoroughly cleaned the surface prior to mounting. I always use 91% isopropyl alcohol with a lint-free rag in such projects. Wiring was straight-forward, and it is quite effective at least to the 17-22F low temperatures I have experienced.

After one year installed, and being in 20F several nights, my tanks have never froze. I am very satisfied with my purchase.



by:

looks great. It will be a few months before I can hook them up.



by:

The decision is still to be determined. The last 2 were a disaster. Without being used, the pads came apart with the rubber separating from the coils. What a mess in cleaning the tanks of the old pads



by:

Completely surprised I got the order the next day. The only "Scary" thing was in my shipping address was to show " My Name" c/o Company name, so it would get to me. It was fortunate the receiver opened the box and "Guessed" who ordered this item. I tried to use your website to initiate this order but your website hung up while filling in the shipping address form, initiating me to call the order in. Thank you for having it in stock and shipping it so quickly. I'll have it installed before the next cold snap early next week.

This product is still functioning and keeps my tanks from freezing in cold weather conditions.

Easy install and fast delivery, etrailer is great. Link to my Youtube channel for an install video - https://youtu.be/UoZFrNEvv-4

Still working great, I never froze last winter and I live in northern Colorado.



by:

I bought these as part of a underbelly overhaul. Went on with out a problem. Ambient Temps are below 60...I have skirting and propane construction heater under TT keeping things warm for tonight.
Time will tell, so far so good.

Last yr we skamped aka ski camp with running water at 13°f. So far so good.



by:

Excellent company to deal with



by:

Install 3 holding take heaters, 1 fresh water tank heater and 5 elbow/ pluming heaters on my trailer. All of the heaters running at the same time draws less than 300 watts so I can now leave then on when towing without having to run my propane heater in the trailer. I added R30 insulation to my underbelly and took a trip to Angel Fire NM where one night it got down to -24 degrees F. None of my tanks froze. I had one temperature probes directly on my black water tank and it was 53 degrees with the -24 outside. Every day was below freezing with temps in the lower teens each night. I believe these are rated at -11 but it is a good idea to have an enclosed underbelly to keep the rest of your pluming warm.



by:

Well, ordering had a hiccup, will not ship to P.O. Box. Figured a solution so away it came. Did hot shipping on Friday got it on Tuesday ??
Product was exactly as described but after comparing to tanks, they really need to be longer in my opinion to cover more surface area. Had a guy install directly to a 20 amp breaker which appeared to be a simple wiring task which I’m not up to doing but was fairly quickly accomplished by tech. Pads heated up immediately but the low amps makes it a slow process in heating. 3 tanks were partially frozen but as of today, Sunday the 17th I was able to discharge all tanks sufficiently enough to go a few days. I’m in bowman Nd with conditions currently-17. I 100% recommend these heating pads. Just don’t expect a complete warming or thawing to occur in under 48 hrs under my conditions. I’ll provide pictures of after install at a later date , it’s cold and windy and I’m inside for the day



by:

went on very easy. tanks aren't flat these are very sticky and should hold up time will tell cold weather here shortly



by:

Installed on a Coachmen Prism 2150LE. The unit did not come with tank heaters, but found to be prewired for them. Added a switch, connected the power wire in the fuse box, installed the new tank heater pads and appears to be working great.



by:

Original order was received defective. Customer service and technical support was very responsive. It appears etrailer's customer service is handled in house and not farmed out to another country. A new item was delivered immediately. I was pleasantly surprised there are still companies that value customer service.



by:

I ordered three electric tank heater pads. The price was great. The delivery quick. I will be ordering more from etrailer. The tank heaters will permit me to take my Chalet camper on ski trips and we will be able to have hot water and showers.



by:

Received two holding tank heating pads today for my rv. I installed without problem in just a few minutes, motorhome was pre-wired. Less than $80 dollars invested. Bid for the work from a local rv dealer was over $1000!

Thanks, etrailer.com



by:

I liked the price of the product. It was very easy to attach to the water tank. I am hooking it up now. I plan on buying more later on to use on other areas. I use my trailer during late year hunts and want running water. The low wattage/ amp use is low.



by:

Purchased for emergency use, like when my water heater failed. My water heater has not failed yet while traveling but this water heater does work for small amounts of water demand.



by:

Reasonable price, delivery on time, product as advertised. Installation was a breeze, thanks to written instructions right on the product. Adhesive seems very durable, make sure you align the product exactly where you want it before application. 5 stars.



by:

Tank was well fitted to the job with the only problem being a persistent leak at the junction of the full hose to the tank. I applied some plumber putty to limit the leak to some degree.



by:

Always great products and service. Etrailer is my go-to place for our RV parts.



by:

So far, we haven't had much of a chance to use the tank heater but the one time we used it, we had no problems. This winter, we will have ample opportunity to test it out and I will add a better review.



by:

These stick on very well after cleaning surfaces with alcohol as instructed. They are warm to the touch on a cold day. Very pleased so far

  • Can A ThermaHeat RV Holding Tank/Step Heater Pad Be Covered With Spray Foam Insulation
    The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 isn't going to get hot enough to cause an issue with the insulation spray, but I wouldn't recommend it since it would be a pain to remove in the event that it malfunctions and needs to be replaced. The manufacturer hasn't tested it but recommends not doing it incase the chemicals in the spray foam could cause any kind of damage to the pad or the wiring.

  • Can I Test the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164
    I spoke to my contact at LaSalle Bristol, he told me that the only way to test the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 is to get the pad/tank cold enough to the point where it turns off/on.

  • Can ThermaHeat RV Tank Heating Pad be Left On
    The heating pad part # 277-000164 can be left on as long as you'd like without causing damage. It has a thermostat that shuts it off at 67 degrees as well. This would be same principal as if you used it in a dump valve.

  • Can the ThermaHeat RV Holding Tank or Step Heater Pad Be Mounted Over a Strap?
    Yes, it can but ideally you would want to make as much contact as possible with the tank to get the most out of the heating pad. The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat item # 277-000164 would not get hot enough to damage the strap but it may allow dirt or debris to get inside any gaps or openings that covering the strap might create. Additionally the pad will automatically turn on at 45 degrees Fahrenheit and auto shuts off at 67 degrees Fahrenheit the strap may...

  • What Is Reason Behind Temperature Range of the Thermaheat RV Holding Tank Heaters
    Thermaheat did test for what the best temperature range should be for the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164. The problem with having it come on lower than 45 is that by the time the water gets to 35 and the heater comes on it potentially could allow the water on the far side of the tank to start freezing slightly since this heats from the outside of one side of the tank. This also helps keep water in any lines that are much further away warm enough...

  • Can Holding Tank Heater be Installed Between Metal Straps
    You will not want to install a heater like the RV Holding Tank Heater # 372HTH-A between the metal straps supporting it and the tank as it can't be in contact with a conductive surface. This heater is 30" long x 13" wide but there are other, smaller options that may work depending on the size of your tank. The ThermaHeat RV Holding Tank or Step Heater Pad with Thermostat # 277-000163 is 25" long x 7-1/4" wide and the ThermaHeat # 277-000164 is 18-1/4" long x 12" wide.

  • Can a RV Holding Tank Heating Pad Be Used with a Trickle Power Source
    No, when using a heating pad like the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 you cannot use a 12v trickle power source. You will need to have the pad hooked up to a battery or through a converter.

  • Keeping Fresh Water Tank and Lines from Freezing in a Lived-In 5th Wheel Trailer
    If you live in the trailer all year then presumably you will be running heaters when it is cold. Provided the hot water heater and plumbing is internal to the trailer then the ambient temperature would prevent it from freezing. But I assume that the water heater is fed from the fresh water tank which is more external to the trailer. To keep it from freezing you could use a tank heater such as # 277-000164. Or we have heating element # W01-1573 designed for freeze protection on holding...

  • Will The ThermaHeat RV Holding Tank Heater Pad Warm A Shower
    The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 would only warm the wall in the space that it's contacting so it wouldn't really do much to knock the chill off in the shower itself. Kind of like a heated floor in a house, you wouldn't warm the bathroom but the tile would just not be freezing cold when you step on it. You'd honestly get more warmth by just plugging in a space space heater and warming your bathroom up prior to showering.

    You can apply the ThermaHeat RV Holding Tank or Step Heater Pad with Thermostat # 277-000164 to the side of your tank if you like, it certainly won't harm anything, assuming it is not touching any conductive surfaces. The reason they are supposed to be under the tank though is to ensure the best heating, so try to get the ThermaHeat Pads # 277-000164 as low as possible to spread the heat throughout the tank where the water is.

The thermostat of the heating pad turns the pad off at 67 degrees but since the pad is smaller I don't recommend using it on the propane tank because it is such a centralized amount of heat in one spot on the tank that is could cause pressure build up which leads to blowing a valve.

The built-in thermostat automatically turns the heating pad on when temperature reaches 45 degrees F and off when temperature reaches 67 degrees F.

What I purpose instead is to use the whole pad on the tank and use a separate pad, just as # 277-000161 or # 277-000162 for the pump. That way you will get the most out of each heating pad. The paper does have to be removed otherwise something could occur that could potentially burn the paper and that could lead to other issues. But if you go with my plan of using 2 pads...
