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
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.
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.

Holding tank heater pad sort of mounted, but as of now, have had no need to use.
by: Jim 12/15/2023
1 year later, still solidly adhered to the bottom of the plastic freshwater tank.

Packaging fail but customer services made it right in a quick and efficient manner!
by: Lila02/23/2021
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: Timothy02/21/2022
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.
by: Ronald 04/10/2024
looks great. It will be a few months before I can hook them up.
by: James07/01/2023
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: Daniel 11/24/2021
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.

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

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.

Excellent company to deal with
by: plocklin01/15/2019
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.

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

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

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: CM12/01/2017
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: David12/04/2017
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: Tim T.10/17/2017
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: Michael G06/18/2020
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: Will L08/28/2017
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: Mike01/15/2020
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: Roderick10/20/2018
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.

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

Great customer care!! Will always purchase from etrailer.
by: Hugh R.09/05/2019
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.

- Could Switch be Used to Power Two of the 18-1/4" x 12" Holding Tank Heater Pad 277-000164As long as the switch can handle the amperage load of two of the heating pads part # 277-000164 yes it would be fine. This heating pad draws 4.8 amps. So the switch would need to be able to accommodate 9.6 amps. The part # D16740 would easily handle the amperage.
view full answer... - Can ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 Attach to Plastic TankYes you could attach the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 to a plastic tank for hydraulic fluid to keep it warmer.
view full answer... - Installation of Therma Heat Holding Tank Heater PadThe Holding Tank Heater Pad # 277-000164 does include instructions. They're actually on the label that is stuck to the pad itself. It can be wired to DC power while your traveling and through a converter when you're connected to a power source. This pad is for tanks that are 29 to 40 gallons so it's certainly more than you need. But I don't see how it would be harmful in anyway. It is generally applied to the bottom of the tank.
view full answer... - Recommended Adhesive For Reattaching A ThermaHeat RV Heater Pad The manufacturer for the ThermaHeat RV Holding Tank or Step Heater Pad # 277-000164 recommends using 3M Hi Strength 90 spray adhesive to reattach the pad if the self-stick adhesive starts to fail. This can be purchased at your local auto parts or hardware store.
view full answer... - Can ThermaHeat RV Holding Tank Heater Pad 277-000164 Keep Up with Michigan Winter TempsThe ThermaHeat RV Holding Tank Heater Pad # 277-000164 has the heating power to actually thaw out a frozen tank and its ambient temperature operating range extends down to -32 degrees Fahrenheit so it will be up to the task of protecting your RV holding tanks from freezing during a cold Michigan winter. ThermaHeat does not specifically indicate whether the -32 is on an insulated tank or not. But this would not really matter anyway. Unless you had an identical tank with an identical amount...
view full answer... - Can the ThermaHeat RV Holding Tank Be Wired Straight To A BatteryThe ThermaHeat RV Holding Tank part # 277-000164 can be hooked up directly to the battery, red to positive and white to ground but it would run continuously if done so. Therefore, I do recommend installing a switch in-line like part # PK34310 so you can control power but it is possible to hook the leads directly to the battery.
view full answer... - Solution to Prevent Plumbing on Slide-In Camper From FreezingHeating pads such as the # 277-000164 are designed for 29 to 40 gallon tanks which are much larger than the tanks on your Lance 650 truck camper. My fear is that they could possibly get too hot and damage the tank. From what you describe, a solution such as a self-regulating heating cable such as the Valterra # W01-1573 for a 25 foot or # W01-1574 for a 50 foot length would be your best bet. The cables operate on 120V AC power, so you'll need an inverter like # DU89FR to power them. I've...
view full answer... - Heating Pads for Holding Tank and Pump on Class B RVSince your tank is 26 gallons having only 3/4 of heating pad # 277-000164 on the tank would only cover 21-3/4 gallons. 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...
view full answer... - Recommended Heating Pad for Stainless Steel Water TankI may have a solution for you, but yes- the ThermaHeat RV Holding Tank Heaters # 277-000164 are designed for more standard tanks that are made from hard plastic. However, you might be able to use something like the Kat's Heaters Oil or Transmission Pan Heating Pad - 5-1/2" x 8-1/2" - 120V - 500 Watts # KH24500, which is be used on 7-10 gallon water tanks. This is the largest tank heater available that would likely work, but you may be able to use more than 1 to help keep your stainless...
view full answer... - Can RV Tank Heating Pads Wire Directly to Trailer BatteryYou can wire your heating pads to the battery directly like you mentioned. They will draw a charge on the battery as long as they are connected. You'd have to verify to be sure but if you have a 30 amp inlet on your RV you most likely have a battery charger that is designed for that panel as well which would keep the battery charged whenever plugged into shore power like you mentioned.
view full answer... - Tip for Removing Adhesive of RV Tank Heating Pad to Install New OneIn order to remove the old adhesive you might find it easier to heat the glue first with like a blow dryer and then try a combination of scraping or products such as rubber alcohol. Once gone, you can then apply the ThermaHeat RV Holding Tank or Step Heater Pad part # 277-000164. It's best to remove as much excess glue as possibly so the unit can attach securely and preform as intended.
view full answer... - Can RV Water Tank Heating Pads be Used on Black and Gray Water TanksThere's nothing stopping you from using a Holding Tank Heater Pad such as # 277-000164 on black or gray water tanks. However with the black water tank adding a heat source could create excess gases which could be a potential problem.
view full answer... - What Is Reason Behind Temperature Range of the Thermaheat RV Holding Tank HeatersThermaheat 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...
view full answer... - Heating Pad for Freshwater Tank on RVFor as big as your tanks are I would recommend going with the part # 277-000163 which measures 25 inches by 7-1/4 inches for each of your tanks. These are designed for the freshwater tanks and would not be needed on grey water.
view full answer... - Does The ThermaHeat RV Holding Tank Heater Pad Require Special Wiring You'd most likely be fine just using some # 16-1-1 with the standard casing but you could also get some wire with exterior rated jacketing if you wanted to go the extra step. You can also get some wire loom # 7509-10 and run it the length of the wires and use electrical tape to secure it. When installing the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 you'll also want to use a switch like # 37212595 to be able to turn it off when not needed to avoid an unwanted...
view full answer... - Can ThermaHeat RV Holding Tank Heater Pads Be Compressed I reached out to my contact at LaSalle Bristol regarding their ThermaHeat RV Holding Tank Heater Pads like # 277-000164, and she did say that the pads should be applied to the bottom of the tank and should not be subjected to any kind of pressure or compression. Compressing the pads like you described would not allow for proper operation and may even lead to damage. Your best option for using the pad will be to try and add some spacers between the brackets to relieve that pressure that...
view full answer... - How To Wire In Three Thermat Heat RV Tank And Pipe Heater Pads The ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad # 277-000162 pulls 0.3 amps and the ThermaHeat RV Holding Tank or Step Heater Pad # 277-000164 pulls 4.8 amps. Assuming that you're having them all run off the same switch and wiring you would be fine using a 10amp fuse # SWC9538 and some 14 gauge wire. You can run the power wire from the battery to a switch, like part # DG52452VP, and then either splice three separate wires from the switch to the pads or one wire from the switch...

- Will 18-1/4" x 12" Holding Tank Heater Pad # 277-000164 Work on 30 Gallon Freshwater TankThe 18-1/4" x 12" Holding Tank Heater Pad # 277-000164 that you referenced would work well for your 30 gallon fresh water tank as it is designed for 29-40 gallon tanks. The heater is powerful enough that it would not need to make contact with the entire bottom of the tank. It would generate enough heat with it's pad size of 18-1/4 inch by 12 inch size to keep it warm. The pad runs off of DC power (what a vehicle runs off of) so you would need to either use a converter to adapt AC power...
view full answer... - Does the ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad 277-000161 Have a Built-In ThermostatThe ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad # 277-000161 will need to be wired to a switch like the Universal-Design Rocker Switch # PK34310 to be turned on and off. The ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad # 277-000161 will constantly be on when the switch is turned on, it does not have a built-in thermostat to turn it off. We do have the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 available, which does have a built-in thermostat.
view full answer... - Do I Need To Insulate ThermaHeat RV Holding Tank or Step Heater Pad 277-000164I have contacted Lasalle Bristol about this and the ThermaHeat RV Holding Tank or Step Heater Pad part # 277-000164 has a built in thermostat that turns the heater off at 67 degrees F. I do not recommend insulating the pad because it could cause it to overheat and not operate as it should. It is not necessary to tape the edges with waterproof tape because the back of the pad has adhesive on it that sticks really well according to our customers as long as you clean the area with an alcohol...
view full answer... - How To Keep Propane Tanks Warm In Below Freezing Temperatures I may have some options for you but the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat - 18-1/4" Long x 12" Wide part # 277-000164 is made for fresh water tanks. 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. Propane does not freeze until -44...
view full answer... - 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.

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