Best 6 Portable and Fixed 12 Volt RV Heaters

Living in an RV can be a wonderful experience. Unlike popular misconception, you don’t have to give up any of your creature comforts. That means you can cook extravagant meals, have a soft bed to sleep in, and even have hot water in your shower. It all comes down to the features you prioritize, and one of the best heating options you should consider for your RV is a 12-volt heater.

This article will help you figure out everything to look out for before buying one. We will also give you our top picks for 12-volt RV heaters, including budget range, durability, and functionality. 

Why Buy 12 Volt Heaters For Your Rv?

While most RVs come with inbuilt heating systems, they are not always sufficient to keep you warm in severely cold climates. Inbuilt systems are plugged into the RV’s propane supply giving them limited mobility. A 12 Volt RV heater is a much more convenient appliance that has portable options allowing you to heat specific portions of your RV more effectively. Users enjoy much more flexibility in temperature changes as well as heat settings. 

What To Look For

Before you can buy your 12-Volt heater, you need to know what to look for. There are several factors you should be considering before you make your choice.

  1. Durability: It is essential to prioritize durability while buying a heater for your RV. Pick a model that is a long-term investment and can take the burden of being toppled around in your moving RV.
  2. Speed: Choose a unit that can heat your space effectively and quickly.
  3. Efficiency: Buy a heater with a high BTU rating that can provide adequate heating for your RV. Heaters with high ratings are effective in larger spaces and provide more uniform heating across your RV. 
  4. Maintenance: While most entry-level heaters can be cleaned and maintained easily, they compromise functionality. High-level heaters can be more demanding for maintenance but ultimately have more settings and last longer. It is best to find a unit that strikes the perfect balance between the two.
  5. Safety Feature: Never compromise on safety when buying a heating appliance. Look for features such as overheating protection that ensure your safety if you accidentally leave the heater running. Additionally, look for models with automatic fail-safe settings that turn off your heater in case it topples over, which is to be expected in a moving RV.
  6. Power consumption: Always look at power ratings when buying your heater and prioritize units with higher efficiency ratings.
