Diesel vs. Propane Heaters: Pros and Cons for RVs.

Compare diesel and propane heaters for RVs. Learn the pros and cons of each heating option to find the perfect solution for your RV lifestyle in the PNW.

When it comes to heating your RV, two popular options stand out: diesel heaters and propane heaters. Both systems have their strengths and weaknesses, and the choice often depends on your specific needs, budget, and camping style. Let’s break down the pros and cons of diesel and propane heaters for RVs to help you make an informed decision.

Diesel Heaters

Diesel heaters are powered by your RV’s diesel fuel supply, or an external diesel fuel tank. This makes them an efficient choice for motorhomes or diesel-powered vehicles. Here’s what you need to know:

Pros:

  1. Cost:

    • Diesel heaters are cheap. Entry level models with great reviews start at $80 on amazon. These are quality units and many say that the justification to spend $1,000 or so for a name brand unit just isn’t there. A new propane furnace costs significantly more if you are going with a Suburban furnace.

  2. Integration:

    • Many diesel heaters integrate can with your vehicle’s fuel system, eliminating the need for separate fuel tanks. However, Odyssey can install your heater. We will not tap into your gas lines. You should have a qualified mechanic share input into whether it is possible for you to tap into your diesel fuel system of your RV. Odyssey can install fuel tanks next to the diesel heater for your install.

  3. No condensation:

    • Diesel heaters put out extremely dry, hot air. They are popular with roof top tent owners camping in the rain. The diesel heater will dry the tent out if left to heat the tent.

  4. Stable Fuel:

    • Diesel fuel is less volatile than propane, making it safer to store and use. Of course, this is not a ‘pro’ that is tangible but it is something to keep in mind.

  5. Backup Heating System:

    Having a diesel heater installed in conjunction with your propane furnace is a great way to ensure you always have a way to stay warm. Redundant systems is never a bad idea. A diesel heater gives you more flexibility to camp in colder climates. BTU’s far exceed your RV’s factory installed furnace.

Cons:

  1. Cost:

    • Diesel Is often slightly more expensive then propane, per gallon.

  2. Installation Complexity:

    • Installing a diesel heater can be more complicated and may require professional assistance.

  3. Noise:

    • Diesel heaters can be noisier during operation, which might disturb light sleepers. If you have a small RV, you may already be used to a loud furnace.

Propane Heaters

Propane heaters are a common choice for RVs due to their availability and cost-effectiveness. They’re particularly popular among campers who frequently boondock or travel in warmer climates.

Pros:

  1. Widely Available Fuel:

    • Propane is readily available at most RV parks, gas stations, and outdoor supply stores.

  2. Quiet Operation:

    • Ducted Propane Furnaces operate more quietly than diesel systems, providing a more peaceful environment.

  3. No Installation:

    • Propane heaters come installed in most RV’s and require no installation.

Cons:

  1. Fuel Efficiency:

    • Propane heaters use propane quick if you are cooking in combination of trying to keep your RV warm.

  2. Cold Weather Performance:

    • Propane systems can struggle in very cold temperatures, as propane’s efficiency decreases when it’s freezing outside.

  3. Fuel Storage:

    • Propane tanks take up extra space, and running out of propane can leave you without heat unexpectedly or unable to prepare a meal for yourself or loved ones.

Factors to Consider

  1. Climate:

    • If you frequently camp in colder regions, a diesel heater may be a better choice due to its reliability in low temperatures. (RV owners in the PNW, this is for you)

  2. Budget:

    • For those on a tighter budget, a DIY diesel heater build is perfect. you can spend $150 and have this heater system roughly installed and keeping you warm

  3. Type of RV:

    • Any type of RV can benefit from a diesel heater. Especially tent trailers (pop-ups) and travel trailers with less insulation. Overall, this type of heater will benefit anyone who likes cold weather camping.

  4. Frequency of Use:

    • Full-time RVers or those traveling in extreme conditions might prefer diesel heaters for their durability, while weekend campers may find propane heaters sufficient.
