Why You Need an RV Battery Heater

Owning and incorporating an RV battery heater into your RV necessities will help save you money from freeze damage. Freezing temperatures can hurt your engine and plumbing if you don’t winterize. But one heater or a combination of heaters can easily prevent that and be an affordable substitute to winterizing. 

In addition to avoiding damage, you’ll be able to use your RV year-round when you have an RV battery heater to keep the engine and other important compartments in the RV warm. Winterizing your RV can be expensive if you store your RV in a warmer location. Or it can be time-consuming to drain the water system and fill it with antifreeze. And those aren’t options for year-round RV travelers. But now it can be with our Xtreme Heaters!

Types of RV Battery Heaters

At Xtreme Heaters, we offer three different sizes for RV battery heaters. You can mix and match the heaters with our three sizes to meet your specific RV needs. One RV testimonial about our heaters said, “They are easy to put into place, reliable as a stone, highly efficient and with their small footprint, are easy to fit just about anywhere.” Another RV testimonial praised “the heaters’ compact size, built-in thermostat, and unbelievable qualities” to make it the perfect fit in their RV. 

To pick the right battery heater for your RV, consider the configuration of your RV and what you want to keep warm. The top priority for RVs should be the plumbing system. If that’s your priority too, identify where the pipes run and where your water tanks (fresh water, black water, and gray water) are located. Next, find the batteries in your RV as they can also be affected by freezing temperatures. If they’re all located in a single compartment, you can measure the dimensions and calculate the volume of the compartment. With that information, you can choose the Xtreme Heater to best suit your RV. 

The Small XHeat is 400 watts and measures 5.75″ x 3.5″ x 5 1/8″. The XXHeat is our medium size to provide 600 watts for the size of 8″ x 3.5″ x 5 1/8″. And the last and biggest option is the large XXXHeat for 800 watts at 8″ x 3.5″ x 5 1/8″. The beauty of having these three various sizes is the ability to mix and match to combine the right heaters for your RV and space. We even have a twin-pack deal for a steep discount! 


As a rule of thumb, RVs have more volume than engine boats so it’s important to size your heater(s) correctly. When it comes to safety, if you opt for multiple heaters, ensure you’re not running too much amperage through a single electrical circuit. Prevent overloading a single circuit by plugging your heater into outlets on separate circuit breakers.
