RV furnaces and heaters keep you comfortable when temperatures drop, extending your camping season into cooler months. Forced-air furnaces are the most common type, distributing heated air through ductwork throughout your RV. Catalytic heaters, wall-mounted heaters, and portable options provide supplemental or alternative heat depending on your needs and installation possibilities.

What to Know Before You Buy

• Furnace BTU ratings should match your RV's size and insulation level—undersized units won't keep up in cold weather.
• Replacement furnaces must fit your existing ductwork and door opening; verify dimensions before ordering.
• Furnaces draw significant 12V power for the blower motor; ensure your battery system can handle extended operation.
• Vent-free heaters are efficient but require ventilation management and may not be legal for sleeping areas.
