RV Holding Tank Heaters

Holding tanks are an essential part of your RV or camper. They allow you to have fresh water even when you do not connect to a city water system. Plus, different tanks hold wastewater until you can dispose of it properly. If you plan on taking your vehicle out during the winter, you’ll need to use RV tank warmers to make sure your tank doesn’t freeze. At UltraHeat, we carry a wide selection of RV holding tank heaters to ensure you can enjoy your vehicle all year long. Our collection includes models of various sizes and power, making it easy to find one that meets your tank's capacity. Our models can protect tanks up to 75 gallons with one heater, larger volumes may require the use of multiple heaters.
