How to Choose the Best RV Heaters & Furnaces

Installation and Maintenance

Some RV heaters are designed for DIY installation, while others may require professional help, especially furnace replacements. Electric heaters are generally simpler to set up. Regular maintenance is key to longevity and safety. This typically involves cleaning dust filters, checking propane connections for leaks, and ensuring vents are clear. Consult your owner's manual for specific maintenance schedules and troubleshooting tips.

Frequently Asked Questions

What size heater do I need for my RV?
The required size depends on your RV's square footage, insulation, and the typical climate you'll be camping in. A general guideline is to look at the BTU output; larger RVs or colder climates will require higher BTU ratings.
Can I use a portable propane heater indoors?
Yes, but with extreme caution. Ensure the unit is specifically designed for indoor use and always use it in a well-ventilated area. Proper airflow is crucial to prevent the buildup of carbon monoxide.
How much electricity do electric RV heaters use?
Electric heaters can consume a significant amount of power, often ranging from 750 to 1500 watts. This can strain your RV's electrical system or battery if you're not connected to shore power.
What is a direct-vent heater?
A direct-vent heater draws combustion air from outside and expels exhaust gases directly outside through a sealed system. This is considered the safest type for RVs as it prevents fumes from entering the living space.
How often should I service my RV furnace?
It's recommended to have your RV furnace inspected annually, typically before the start of the cold season. Regular cleaning of filters and checking propane lines can also help maintain optimal performance.
