  • 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
  • Thermal Aging Test (UL)

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.

This is a product unworthy of etralier's inventory. The product is made up of thin heating elements and a thermostat sandwiched between two rubber type pads. In theory, they should work great. In practice, they don't work at all. After a single day, the pads separated between the two layers everywhere the heating elements and material holding them were located-all except for a 1/4" area around the perimeter of the pad, so the lower pad was just hanging down loose and barely held on to the top layer. This heating pad failed even before I connected the power connections which I had planned on the next day. Removing the bottom pad was fairly easy as not much was holding it on. However, the upper pad was near impossible. After removing the rubber layer and the heating elements, the sticky adhesive left behind was impossible to remove. Nothing would budge it, not alcohol, acetone, or even mechanical. I have yet figured out a way to remove it from the tank so now the entire underside of the tank has dirty adhesive I cannot remove. I strongly recommend buyers DO NOT BUY THIS PRODUCT AS YOUR WILL REGRET IT! It will fail, and leave you with a mess to try to clean up the best you can if you plan to replace it with a higher quality product than this. etrailer, you should immediately remove these from your inventory, send the ones you have back to wherever you sourced them and stop selling them. This has been a nightmare.

The product is great, we have reordered this a few times. It is worth its value. However the shipping service was a fail. It took more than 2 weeks to get this parcel, and the tracking was not reliable.

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.

Just installed and appears to be working as advertised. The website product details really should say that minimum installation temp is 60 degrees. It doesn't! My son and I had to install it anyway. No choice. Then in stalled R2 doulbe-sided foil backed insulation under the tank ( he's going off the grid in his travel trailer) and we had to do all we could to insure his water system would not freeze. The heating pad is working and we're filling the water system tomorrow. Also the PK34310 rocker switch has absolutely no info about what terminal get connected to what wire! You really need to to have info on your website for this. After some digging online I was able to find the proper wiring connections. It would require almost no effort on etrailer's part to do this.

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.

Within six months the entire cover was torn to a point it was no longer useful - due to simple wind damage that it should have been able to withstand.

  • Therma Heat Holding Tank Heater Pad is Not Getting Warm with Power Applied
    The Therma Heat Holding Tank Heater Pad # 277-000163 referenced in your question will automatically turn on at 45 degrees Fahrenheit but will auto off at 67 degrees Fahrenheit. If the pad is not getting warm with power applied to the leads, it is likely too warm outside for the pad to start working. As long as power is applied to the unit, they will do a great job of warming your RV tank when the temperature dips below 45 degrees. You might try testing the unit at night when temperatures...

  • Can Multiple RV Heater Pads with Thermostat 277-000163 Be Wired Together
    My contact at Patrick Industries advised that their RV Heater Pad with Thermostat # 277-000163 could be parallel wired in up to 3 pads total provided that the DC power source has enough current for the 5.8-amp draw from each pad. Typically a 15-amp circuit can handle three since they cycle on and off. These pads are suitable for your 45-gallon grey and black water tanks; one per tank is enough according to my contact. For your 70-gallon fresh water tank you'll want to use two and position...

  • What Type of Power Does the 25" x 7-1/4" Heater Pad with Thermostat for RVs # 277-000163 Run On
    The 25" x 7-1/4" Heater Pad with Thermostat for RVs # 277-000163 will only produce heat when attached to a power source. If you disconnected the power source it would turn off. 12 volts is DC power though. You would need an inverter if you wanted to convert it to AC power.

  • Can ThermaHeat Heater Pad be Insulated with Spray Foam
    I spoke with my contact at ThermaHeat regarding the Heater Pad # 277-000163 that you referenced. He did state that they don't really recommend insulating the pad with foam like what you are describing, as this can potentially affect its function and may interfere with the surrounding wiring as well. The pads are designed to attach directly to the tank. I have attached a short video demonstration on the heater pad that you can also check out.

She stated that the pads will work just fine with your 12V RV battery that operates between 11 and 13.5 volts. You will not have any issues.

  • Can Insulating Blanket be Installed Over Therma Heat RV Holding Tank Heater Pad
    I spoke with my contact at Therma Heat regarding the Heater Pad with Thermostat # 277-000163 referenced in your question. She stated that it is perfectly safe to install an insulating blanket over the heating pad. Please note though, that in order for the pad to be effective, it will need to be placed on the bottom of the tank, not the top. I have attached a short video demonstration on this product that you can also take a look at.

  • Would the Heater Pad Part # 277-000163 Be Suitable for a 46 Gallon Water Tank
    According to my contact at Patrick Industries, the 25" x 7-1/4" Heater Pad with Thermostat part # 277-000163 would be suitable for a 46 gallon water tank. If you were to use this heater on a water tank larger than 46 gallon then you would want to use two of them wired together but as mentioned, the one pad will work with your 46 gallon tank just fine. As you probably read, this pad has a peel and stick application with an integrated thermostat that will turn on when the water in the tank...

  • Should Adhesive Backing of ThermaHeat RV Holding Tank or Step Heater Pad Be Left On
    You'll want to remove the adhesive backing of the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 before you leave it underneath a tank permanently. It probably wouldn't be a big deal in the short term but long term it's hard to say what the backing will do.

  • Do RV Gray and Black Water Tanks Require Heaters
    The good news is that you don't have to have heaters on black and gray water RV tanks. The fresh water needs a heater as you can't put any antifreeze in it. But since you don't have to worry about poisoning the water in the black and gray water tanks you can use RV antifreeze in them and not have to worry about them freezing. That said, the ThermaHeat tank pads do not have thermostats built into them.

  • Can the 25" x 7-1/4" Heater Pad with Thermostat # 277-000163 Be Used with a Wind and Solar System
    The 25" x 7-1/4" Heater Pad with Thermostat # 277-000163 is typically used for RVs but if your wind and solar system is a 12V DC power system or you connect it to a DC-to-AC converter then there shouldn't be any issue with powering this pad from your wind and solar system. Please note that this heat pad is meant to be used on a water system. This heating pad has a voltage rating of 13.5V and an amp rating of 5.80A. A review video has been linked for you to reference as well.

  • RV Water Tank Heating Pad
    That is heavily dependent on the specific application and proximity of heated pad to potentially combustible material. This heater pad is designed primarily for installation onto the bottom of exposed waste tanks, or steps. That doesn't mean it can't be used safely for enclosed fresh water tanks, it can, but concern for enclosed installation must be taken in account for safety.

  • Does ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 Heat Both Sides
    The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 that you referenced does radiate heat on both sides of the pad. When the ambient temperature drops below 45 degrees the heater comes on and won't go off until it has reached 67 degrees.

  • Can I Wire A Holding Tank Heater Into A Cigarette Lighter
    Yes you can wire the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat - 25" Long x 7-1/4" Wide Item # 277-000163 into a cigarette plug. The red wire is for power the white wire is for the ground.

    The ThermaHeat RV Holding Tank or Step Heater Pad part # 277-000163 do get hot to the touch but not enough to burn you as they has a 67 degree cutoff. The outside of the pad should not exceed the shutout off temp although there are a few factors to this.

    For 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.

  • How to Check for Proper Operation of ThermaHeat RV Holding Tank Heating Pads
    RV holding tank heating pads like # 277-000164 and # 277-000163 operate on an automatic thermostat. The pads will automatically turn on at 45-degrees Fahrenheit and turn off at 67-degrees Fahrenheit. If you are nearby to the RV when the tanks are in a sub-45-degree environment you should be able to feel warmth from the pad if it is cycled on. I confirmed with LaSalle-Bristol, the manufacturer of ThermaHeat pads, that the thermostats in these pads read the tank surface temperature and...

  • Can ThermaHeat RV Holding Tank or Step Heater Pad be Installed Between Tank and Holding Bracket
    Yes, the weight of the tank when full would compromise the integrity of the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 if you placed it between the tank and mounting brackets. This pad actually has a peel-and-stick installation so you don't need to use anything else to hold it in place. Just make sure that the mounting surface is clean so that it is able to hold well.

  • Can an RV Tank Heater Be Used for Warming a Battery
    The reason is that a holding tank heater pad like the # 277-000163 you've looked at isn't designed to heat a battery. It's designed to heat a large 29-40 gallon tank, not a much smaller battery. A thermal battery heater would usually wrap around all 4 edges of the battery and gently heat it from all sides, while the tank heater isn't meant to be folded or wrapped around anything. You'd be better off using an actual battery heater, like one of the ones I've linked for you. Using the product...

  • Will ThermaHeat Holding Tank Heater Pad Damage Fresh Water Tank If There Is No Water In It
    I spoke with my contact at LaSalle Bristol and he verified that there is no risk of damaging your fresh water tank if the ThermaHeat Holding Tank Heater Pad # 277-000163 comes on when the tank is empty. As you mentioned in your question, the pad will automatically turn on when the tank's temperature (not the outside temperature) reaches 45 degrees but it will automatically turn off as soon as it gets up to 67 degrees. This means it will not get near hot enough to cause any damage to the...

  • Are Tank Heaters Needed for Gray and Black Water RV Tanks
    The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 can be installed on gray and black water tanks but in reality it's only really needed on freshwater tanks. You can easily put antifreeze in the gray and black water tanks and piping and you'll prevent them from freezing. Since the freshwater can't have that you'd have to use the heaters. These would also help with preventing the pipes from freezing as well.

  • Will ThermaHeat RV Holding Tank Heater Pad Work on Hard Plastic Tank Inside Vanagon Westalia
    The ThermaHeat RV Holding Tank Heater Pad # 277-000163 will absolutely work on the hard plastic tank inside your Vanagon Westfalia Camper. The pad features an integrated thermostat that will turn on the pad only when the tank's temperature reaches 45 degrees, so you don't have to worry about it getting too hot inside the camper. It will then turn back off as soon as the tank gets back up to 67 degrees. I have attached a short video review that you can also check out.

  • Could ThermaHeat RV Holding Tank # 277-000163 be Used With Diesel Tank
    Yes, you could use the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 that you referenced with a diesel fuel tank. This pad turns on when it's below 45 degrees and then off when 67 which would be ideal for diesel fuel. I attached a review video for the pad for more info as well.

    You can attach the ThermaHeat RV Holding Tank Heater Pad # 277-000163 to the coroplast wrapping around your tank but it is not going to be as effective. For best results you really want the pad to make direct contact with the tank (toward the bottom) so that it keeps the tank warm especially once the outside temperatures start to drop. Also note that the pad features a built-in thermostat that automatically turns the heating pad on when the temperature drops to 45 degrees (and off when...
