Full-contact, weatherproof heating pad helps prevent your RV holding tank or step from freezing. Built-in thermostat automatically turns the heating pad on and off depending on the temperature of the tank or step. Easy, peel-and-stick installation.
Features:
Specs:
The Therma Heat RV tank and step heating pad meets the following certification standards:
Note: This heater pad should be installed on non-conductive surfaces only.
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.
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.

I ordered 6 pads and tested them all in the deep freeze with an a meter before installing. All 6 worked properly.
After a year on the trailer, they still all work properly and adhesive is holding well.
Easy to order online. As described. Prompt delivery. This is a tank heater for my RV and it went on smoothly. I am replacing a five year old heater pad that eventually started peeling off. This time I filled the tank first to stretch the plastic tank before applying the pad. Time will tell if it stays on.
Wired up, but would not power on. still stuck to my tank a year later because the adhesive actually works, unlike the electronics
Maybe I had a dud, but I cannot recommend this product
Just got them today, very quick shipping.
I’ll install Monday using etrailers video
only 1 out of 4 that I have worked. The one that works is great and has been working for 2 months now. The 3 that don't work were all dead on arrival and all do the same thing. Once plugged in, they turn on normally for the first cycle and heat for 5 minutes and then after that they cycle on and off and do no good. They turn on for maybe 0.1 seconds and then turn off again for about 15 seconds. I've spent many hours diagnosing and trying different things with no luck. I've pulled my hair out trying to figure out the problem and have come to the conclusion that the thermal switches in these things are junk. I have also spent many hours attempting to find the manufacturer in order to speak with a competent tech with no luck. My guess is that they come straight from China and hit several distributors before they get to Etrailer. I know they go through at least 2 distributors. Good luck to all future buyers and beware, I hope you get a good one.
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.
WE NEEDED IT FOR A QUICK INSTALL FOR CUSTOMER PICK UP AND BILL CAME THRU FOR US. HE WAS FANTASTIC TO DEAL WITH.
Easy website and transaction to navigate. The fastest shipping and handling I've ever seen! Thank you!
Spotty heating and only certain sections of the pad. Also, it's exactly the same product as the most commonly sold brand but: it's more expensive, doesn't come with an inline fuse, and doesn't come with ring terminals. Very disappointing product.
Holding tank heater pad sort of mounted, but as of now, have had no need to use.
Everything showed up. Both sets of steps are installed in less than a half hour.
1 year later, still solidly adhered to the bottom of the plastic freshwater tank.
Great fast shipment
Packaging fail but customer services made it right in a quick and efficient manner!
WOULD HAVE LIKED IT TO BE PACKED INSTEAD OF LOOSE
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.
Items delivered quickly. They match exactly whet the description says. Installed easily and quickly.
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.
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.

Still working great, I never froze last winter and I live in northern Colorado.
looks great. It will be a few months before I can hook them up.
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
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
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.
Do you have a question about this RV Fresh Water?
