Why ThermaHeat?

When the outside temperature is cold enough, the gray water or black water dump valve pipe or elbow on your RV will freeze. This stops you from being able to dump your gray water or black water tank. Furthermore, the frozen water could potentially cause cracks or other irreparable damage, which would mean you would have to replace the pipe.


The full-contact ThermaHeat heater pad will prevent this by keeping your pipe warm during freezing temperatures. It can also completely thaw out a pipe if it's already frozen, assuming that it hasn't 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 pipe if not used properly.


Installation and Wiring

ThermaHeat Peel-and-Stock Installation

This heater pad has easy, peel-and-stick installation. The flexible carbon fiber material is designed to fit the contours of any valve pipe or elbow surface. The pad is meant for use on black water and gray water pipes, but can be installed onto freshwater pipes as well.


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. The pad wires into a wall switch on your RV, letting you turn it on and off as needed.


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.

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:

The pad works well. Below 17F it is unable to keep up and the system freezes.



by:

Performs exactly as described and would highly recommend them for someone looking to give their trailer protection while operating during freezing temperatures. Easy to install and wire!



by:

I have 4 of these installed (2 for a year and 2 for 2 years). 2 I installed last season replacing 2 that failed. presently only 1 of 4 is functioning, these seem to only last about a year, 2 years tops based of my replacement rate.



by:

Have not installed this yet, but hope it will keep my Dupree Valves from freezing and cracking like they did before I replaced them, they exposed to elements on a Silver Streak.. Appreciated such fast and courteous service from etrailer!



by:

Easy install, appears to work as designed. Instructions say to clean surfaces w/alcohol, I'm a believer in Lacquer thinner myself, cleans a preps plastic a lot better imop.



by:

Works as designed, wired it in with the tanks heaters.



by:

When I read description it made me believe these heaters had an internal temperature on/off when in fact they do not. That was only Reason I purchased. I’m sure they work as made but they will not work as I anticipated.



by:

2nd purchase from e trailer works perfectly and got here fast. Thx



by:

Excellent adhesion to pipe, good wire quality, now I have to wait for it to get cold to see if it works!

  • 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...

  • Recommended Water Tank Heater For A 13 Gallon Flat Water Tank
    Good morning and thank you for your question. I recommend for you the Therma Heat RV Holding Tank Heater Pad # 277-000164. This is a 18-1/4" long x 12" wide heater pad so you will want to make sure your tank has adequate surface area. There is also a 25" Long x 7-1/4" Wide pad available # 277-000163 if that will be a better fit. The best thing about this pad is the built in thermostat that automatically operates the pad. It will only come on when the temperature drops below 45 degrees....

These weatherproof heating pads helps prevent the holding tanks from freezing with a built-in thermostat. It is an easy, peel-and-stick installation.

  • Does ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad 277-000162 Have Thermostat
    The ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad # 277-000162 does not have a built-in thermostat.

  • Options For Heating And Insulating 1/2" Pex Pipes
    Hello Kurt, about how long is that section of pipe in your picture? Both the 8 inch long # 277-000162 and the 13 inch long # 277-000161 are safe to use with 1/2" pex pipes. Using a larger pad will provide more heat so if you can fit the larger pad that will be your best bet. Keep in mind that these pads were made for a 3" diameter pipe, so you might need to get creative in order to fit it to a 1/2" pex pipe. Adding additional insulation is also a good idea, although we do not offer any...

  • RV Holding Tank Heater Pad for 40 Gallon Tank
    An elbow heater pad is not designed to be used with tanks it fits on pipes. For example the 13" x 3" Elbow Heater Pad for RVs # 277-000161 is designed to be used on 3 inch pipes while the 8" x 3" Elbow Heater Pad for RVs # 277-000162 is designed for use with 1-1/2 inch pipe. For your 40-gallon RV holding tank I highly recommend the ThermaHeat RV Holding Tank Heater Pad w/ Thermostat # 277-000163.

  • Can Multiple Therma Heat Heater Pads be Wired to Single Switch
    Multiple heating pads like the Therma Heat 25 Inch x 7-1/4 Inch # 277-000163 and the Elbow Heater Pad # 277-000162 that you have can be wired to a single switch. If you are not getting enough voltage with your current setup, it's possible that the switch you are using cannot handle the total amperage of the heating pads. The larger pads draw 5.8 amps (each) and the elbow pad draws 0.3 amps. A higher rated switch like the Pollak # PK34310 might be a better option if your existing switch...

  • Can the Kats Heaters Handi-Heat Magnetic Heater be Used to Heat Water Pipes on an RV
    The Kat's Heaters Handi-Heat Magnetic Heater # KH1155 was specifically designed to heat up various fluids in the engine of your vehicle. Since it has a heat output of 300 F - 400 F I recommend going another route. A better way to go is with the Therma Heat elbow pads. We have part # 277-000162 which is 8" x 3" and part # 277-000161 which is 13" x 3". Either one of these will do a great job keeping your water pipes warm as long as they do not exceed 3" in diameter. Just connect one wire...

  • Can ThermaHeat RV Pads be Run Off of 12V Power - EMAILED LASALLE BRISTOL
    Both ThermaHeat RV Pads # 277-000161 and # 277-000162 that you referenced are designed for 12V systems so they will work if you're just using the house battery bank on your rig. Since the optimal voltage from a 12V system is around the 13.5 mark that's why the specs list it as that.

  • Is there a Heating Pad for Small Holding Tanks on a Pop-Up Camper
    We do have some smaller heater pads such as # 277-000161 at 13 x 3 inches or # 277-000162 at 8 x 3 inches. The larger one draws 0.62 amps at 13.5 volts. The smaller one draws 0.3 amps at 13.5 volts.

    Sorry to hear that your heating pads part # 277-000162 and part # 277-000161 are not working properly.

Make sure the total amp draw on the circuit is appropriate for its’ capacity. Make sure the placement of the pad is...

    To install the Tank Heater Pads part # 277-000164, part # 277-000161, and part # 277-000162 together you will simply need to run them in parallel. This means that you will daisy-chain all of the positive (Red) wires together and connect them to the battery on your RV, and you will daisy-chain all of the negative (White) wires together and ground them. You can use the Pollak Universal-Design Rocker Switch # PK34310 between the battery and the pads as a way to turn them on and off. Since...

  • Can More than One Heating Pad be Used on a 100 Gallon Fresh Water Tank
    You could use more than one holding tank heater if you wanted to and there are different options available. Pad heater # 277-000164 is one option. There is also another model, # 277-000163, with different dimensions. We also have elbow heater pad # 277-000161 (for 3 inch pipe) and # 277-000162 (for 1-1/2 inch pipe). And we have several self-regulating heating elements: # W01-1572 (15 feet), # W01-1573 (25 feet), and # W01-1574 (50 feet). These were designed for freeze protection for holding...

  • Heating Pads for Holding Tank and Pump on Class B RV
    Since 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...
