Running an RV Furnace While Driving in Cold Temperatures

Running an RV furnace in cold temps is a common dilemma for RV owners. Here are some tips to ensure its safe and efficient use on the road.

  1. Check propane: Before leaving, make sure you got enough propane to fuel your furnace for the trip. Propane appliances consume lots, so bring extra tanks and refill along the way.
  2. Safety first: Install smoke and carbon monoxide detectors in your rig. Also, keep combustible materials away from heating vents, and don’t use the furnace when refueling or driving through windy conditions.
  3. Watch your battery: Running your RV furnace while driving uses up electricity. Make sure your batteries are fully charged beforehand and consider a generator or solar panels as backups.

Other important details to keep in mind include insurance issues and thermostat settings for optimal heat throughout the day. It’s recommended that you seal off unused spaces in your RV (like windows or curtains) to prevent heat loss. 

Additionally, investing in an ARP system can regulate high-temperature issues with the fridge or generator exhaust fumes. Lastly, make use of your cab heater or dash air for extra heat during long drives.

Follow these steps and you can safely heat up your rig while driving, just remember ventilation and monitor flame discharge vents regularly! 

It’s your call; heat up the rig or burn down the highway?

How Often Can You Run Your RV Furnace While Driving?

Can you use your RV furnace while driving? Yes! If you’ve got propane in the tank and your rig is powered by it, you’re good to go. But, bear in mind some safety measures.

Check the position and settings of the heating vents and make sure they don’t blow hot air onto curtains or other inflammable items. Also, have a look at the exhaust line for snow build-up or debris. 

Keep an eye on the temperature setting as overheating may lead to damage or fire. Travel with windows open for fresh air circulation and to avoid carbon monoxide poisoning. Install smoke and CO detectors too.

Remember that long-term heating can drain batteries – make sure they are sufficiently charged.

Proper Ventilation and Heating Maintenance for RV Furnaces While Driving

It’s possible to run your RV furnace while you drive, as it uses propane and electricity to heat the rig. 

  • But before you turn on your travel trailer furnace, make sure there’s proper ventilation. 
  • Blocked heating vents and closed windows can lead to carbon monoxide poisoning, which is fatal.
  • For a safe and comfortable journey, keep windows slightly open for air circulation
  • Check the pilot light and ignition system before every trip, and carry extra fuel and batteries as a backup

Jerry C., an ARV forum member, shares his story of a fifth-wheel fire incident due to negligence of proper maintenance. Therefore, service your RV furnace at least once per year

What to Do in Case of Accidents or Issues When Running an RV Furnace While Driving?

RV furnaces can be useful in cold temperatures but check safety precautions first.

  2. Check the fuel lines and exhaust system. 
  3. Monitor the heating vents for smoke or flame
  4. Install a smoke detector and carbon monoxide alarm
  5. Make sure there’s enough propane for heating and hot water. Ensure the battery is charged. 
  6. For extra air insulation, use curtains to separate the cab area from the living spaces.

Alternative Heating Options for RVs While Driving

Keep warm when driving in cold weather without your RV furnace. Possible! Consider alternative heating options. Here’s the lowdown:

  1. Get a propane heater, designed for travel trailers: Safer and more efficient than an RV furnace.
  2. Buy an electric space heater: It runs off your generator or shore power when parked.
  3. Install a diesel-fired auxiliary heater: Perfect for long trips in freezing temperatures.
  4. Use your dash air and curtain off the living area to stay warm.

Make sure you have enough propane or fuel and follow appliance instructions to the letter. Also, install a smoke detector and carbon monoxide detector.

Don’t rely on your RV furnace while driving. It isn’t always possible to access electricity and propane in remote areas. Plus, the airflow from driving can extinguish the pilot flame, or cause fire hazards due to heater discharge vents obstructions.

Make sure the benefits of heat outweigh the risks of fire, fuel consumption, and carbon monoxide poisoning. Stay safe on the road!
