  • 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.

  • Where are Install Instructions for ThermaHeat RV Holding Tank Heater Pad w/ Thermostat # 277-000163
    The instructions for the ThermaHeat RV Holding Tank Heater Pad w/ Thermostat # 277-000163 that you referenced are actually on the back of the pad on the label that has the UPC code.

  • 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.

  • 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....

  • 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...

  • Compatible Power for ThermaHeat RV Holding Tank Heater Pad
    The ThermaHeat RV Holding Tank Heater Pad w/ Thermostat # 277-000163 is compatible with 12 volt DC power but can be used with a converter to adapt to AC power. This pad is designed to be used on holding tanks with capacities between 29 and 40 gallons and simply sticks onto your tank.

  • Is ThermaHeat RV Tank Pad Needed on All Water Tanks of an RV
    The only tank that actually requires a heating pad is the freshwater one because the other tanks you can simply pour RV antifreeze into and not have to worry about heating the tanks. That said if you wanted to you could install Thermaheat pads like the part # 277-000163 on all of the tanks. This is DC powered like you mentioned as well. The pad measures 25" Long x 7-1/4" Wide.

  • Heating Pad for Freshwater Tank on RV
    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.

  • Heating Pads For Fresh Water, Grey and Black Storage Tanks To Prevent Freezing
    Yes, the ThermaHeat RV Holding Tank or Step Heater Pad # 277-000164 can be attached to the base of a black tank, grey tank or fresh water tank to help prevent the contents from freezing. The pad it thermostatically controlled and will turn on when it senses the temperature drop below 45 degrees Fahrenheit. Once it reaches 67 degrees Fahrenheit it will turn back off. The pad has been tested in temperatures as low as negative 32 degrees Fahrenheit. This pad is 18-1/4" long and 12" wide. We...

  • 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.

  • 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...

  • Adding ThermaHeat RV Holding Tank Pad to DC Fuse Panel
    Yes, you can use two of the ThermaHeat RV Holding Tank or Step Heater Pad # 277-000163 connected to your DC fuse panel. You could do this with both pads running to individual switches, or if you wired them in parallel you would only need to use one switch, such as the Universal-Design Rocker Switch # PK34360, because the pads draw 4.8 amps and this switch is rated for 20 amps. Essentially, so long as your switch is rated for the appropriate amperage you would run the wire from the fuse...

  • 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. This this pad sticks right on your tank and has a thermostat which turns on when your tank...

  • Installation of Heating Pads on RV Holding Tanks
    Holding tank heating pads such as Thermaheat 18 x 12-inch # 277-000164 and 25 x 7-inch # 277-000163 should not be trimmed or cut. When you install one of these on your plastic holding tanks you'll want to be sure to first clean the surface with 91% isopropyl alcohol (available at any pharmacy) to remove any residue that could interfere with the pressure-sensitive adhesive that will hold the pad in place.

  • Heating Pads for 50 Gallon Fresh Water Tank
    For your 50 gallon fresh water tank you will want to use two of the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 wired together. You can use the ThermaHeat Elbow Heating Pad # 277-000161 as well, but this is a pad for 3 inch pipes so you will want to put it there as opposed to your tank. You can wire these together in parallel by "daisy-chaining" each of the red wires together and connecting them to your RV's battery; you will then also daisy-chain the white...

  • 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.

  • Is Switch Required for ThermaHeat RV Holding Tank Heater Pad # 277-000164
    The ThermaHeat RV Holding Tank Heater Pad # 277-000163 can be wired to a switch like # PK34310 but it is not required for operation. The built-in thermostat will automatically turn on the pad when the tank's temperature reaches 45 degrees and automatically turn of when the temp rises to 67 degrees.

  • Options for RV Use During Winter, Preventing Pipes and Tanks Form Freezing
    There are several options such as the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat, # 277-000164 or # 277-000163, that will be placed against the holding tank. These weatherproof heating pads helps prevent the holding tanks from freezing with a built-in thermostat. It is an easy, peel-and-stick installation.

  • 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.

  • 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...

  • How To Secure and Wire the ThermaHeat RV Holding Tank Pads
    The ThermaHeat RV Holding Tank part # 277-000163 has an adhesive backing so no further method of securing it would be required nor is there anything I can recommend. I would also not recommend covering it for protection as this could be a fire hazard. it In regards to operation, it would work with pretty much any toggle/rocker switch like part # PK34310. I have attached a sample diagram I made to help with the wiring.

  • Using ThermaHeat RV Heater Pad on Holding Tank with Coroplast Wrapping
    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...

  • Water Tank Heaters for Well Insulated 30 Gallon Tanks on a 2017 Ford E450 Box Van
    ThermaHeat RV Holding Tank Heater Pad # 277-000163 or any of the others needs to be in direct contact with the tank so you would need to clear away anything that is in the way of making that direct contact. But considering what you will be doing I strongly recommend having a spare battery with you as well as an AC charger such as # CTEK56353. Safety First!

  • In-Line Fuses For Therma Heat RV Tank Heater Pad
    You do need to make sure you are properly connected to fuses for a single unit as the # 277-000163. This is a thermostatically controlled pad. If you are running more than one, you need to run them parallel. It would be wise to use a combined amperage fuse as you stated. You also want to make sure if you use a switch that it can cover the amperage. Each pad draws 5.8 amps, so a 15-amp or better switch will work, like # PK34571.

  • Wiring Multiple Heating Pads to Switch Diagram
