Best RV Heaters: Keep Your RV Warm, Dry, and Mold-Free

The Isiler Space Heater is a powerful and compact heater that will fit inconspicuously in most RVs, making it a great little space-saving heater that’s offered at an extremely competitive price point. Constructed from durable rust-resistant and fire-retardant materials, this ceramic heater is a self-regulating heater that features automotive overheat and tip-over protection to avoid accidental fire or burning of surrounding materials.

It quickly produces up to 1,500 watts of heat that is capable of heating up to 108 square feet of space. The adjustable thermostat can be incrementally altered to produce temperatures between 41 and 95 degrees Fahrenheit, allowing you to completely customize the amount of heat you need and want to stay warm and comfortable. Weighing a mere 38.8 ounces and equipped with an ergonomic handle, this little heater is super lightweight and easily portable. The manufacturer does recommend leaving three feet of space between furniture and the heater, which may be difficult in some smaller RVs.
