RV Furnace Mastery with E3 Camping

In the tranquil embrace of a campground, there’s nothing quite like the warmth that emanates from your RV’s furnace on a cool morning. At E3 Camping, we understand the pivotal role your furnace plays in enhancing your camping experience. Let’s delve into the intricacies of RV furnace care, ensuring your cozy haven on wheels remains a source of quiet warmth and comfort.

To comprehend the operation of an RV furnace, we must recognize the four fundamental requirements for its proper functioning: venting, ducting, power, and propane fuel. Let’s explore each of these aspects to empower you with comprehensive knowledge.



The furnace relies on a clear vent for the discharge of carbon dioxide and intake of fresh air for combustion. The exterior side vent is strategically positioned to facilitate this vital process. Blocking this vent can lead to ignition issues and potential overheating. Keeping the vent unobstructed is crucial for the optimal operation of your furnace.



Efficient heat delivery into your RV is facilitated by ducting, whether through floor vents, interior side wall vents, or direct vents into the coach. The arrangement of ducts should minimize deflection, ensuring the least bends and the most direct path for efficient heat dispersion. Taped joints and tight materials contribute to the effectiveness of the ducting system. Avoid blocking vents to maintain an unobstructed flow of warm air, preventing heat buildup and furnace limitations.



Powering RV furnaces requires a stable supply of either 120 VAC or 12V DC from your converter and RV coach batteries. Insufficient voltage can lead to various operational issues. Low voltage may prevent the blower wheel from spinning fast enough, hindering the activation of essential components. Ensuring a proper power supply is vital for the seamless functioning of your furnace.


Propane – Fuel:

Propane serves as the primary fuel source for RV furnaces, and its pressure must fall within the optimal range of 10 to 12 inches of water column. This ensures the necessary pressure for combustion and heat creation. Propane pressure that is too low can impede the furnace’s ability to generate heat effectively. Regular checks and maintenance of propane systems are essential to prevent potential issues.


At E3 Camping, we stay at the forefront of RV heating technology, introducing you to the Truma Combi eco plus. This innovative system seamlessly integrates gas and electric heating elements, offering self-sufficiency, electrical mode at the campsite, and mixed mode for low outdoor temperatures. Embrace European ingenuity tailored to the North American RV lifestyle for unparalleled camping comfort and convenience.


Propane Pressure Test:

Conducting a propane pressure test can be done safely by turning on one burner on the stove. Observe the flame, ensuring it has a blue tip just above the burner grate. Switch the thermostat to Furnace and monitor the flame. A properly functioning furnace will cause a decrease in flame height, but it should remain relatively consistent. Any deviation, such as a yellow flame or significant reduction, indicates a potential gas pressure problem. In such cases, it is advisable to seek professional assistance to address the issue.


Maintenance Tips to Keep Your Furnace Running Smoothly:


  1. Vent Cleaning: Use compressed air to blow dust and debris out of the burn chamber from the outside vent. Ensure proper safety measures to avoid soot exposure.


  1. Propane Regulator Check: Regularly inspect the propane regulator for any debris or blockages that might affect its vent. Clear any obstructions to maintain optimal functionality.


  1. Duct Inspection: Examine ductwork for wall-ducted or floor-ducted furnaces. Look for kinks, tears, or excessive bends that may hinder the efficient flow of warm air.


  1. General Cleanliness: Keep the area around the furnace clean to allow for effective heat dissipation. A clutter-free environment contributes to the furnace’s optimal performance.


By adhering to these maintenance tips and embracing the technological advancements in RV heating, you can ensure that your furnace operates safely and efficiently, providing a cozy haven during your outdoor adventures.
