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

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.

Common RV Furnace Problems and How to Fix Them.

Your RV furnace is essential for staying warm during those chilly nights on the road. But like any appliance, it can run into issues that leave you shivering. Understanding common RV furnace problems and how to fix them can save you time, money, and discomfort. Here’s a step-by-step guide to diagnosing and resolving the most frequent furnace issues.

Common RV Furnace Problems

1. Furnace Won’t Turn On:

   • Possible Causes: Faulty thermostat, dead battery, blown fuse, or lack of propane.

   • Solution: Check the thermostat settings and battery power. Ensure propane tanks are full, and inspect fuses or circuit breakers for damage.

2. Blower Turns On, but No Heat:

   • Possible Causes: Ignition failure, dirty burner assembly, or malfunctioning gas valve. Most common is a bad sail switch.

   • Solution: Inspect the igniter for dirt or wear. Clean the burner assembly and ensure the gas valve is operating correctly. Remove furnace access panel or furnace from its mounting point. Test Sail Switch.

3. Furnace Cycles On and Off Too Quickly:

   • Possible Causes: Overheating due to restricted airflow or a faulty thermostat. Thermostat could be mounted in the wrong area of the RV.

   • Solution: Check air intake and exhaust vents for blockages. Replace the thermostat if necessary.

4. Strange Noises:

   • Possible Causes: Loose components, worn blower motor, or debris in the fan.

   • Solution: Tighten screws, inspect the blower motor for damage, and clean out any debris.

5. Weak Airflow:

   • Possible Causes: Dirty air filters, clogged or poorly installed ducts, or a failing blower motor. Low battery could be a cause.

   • Solution: Clean or replace air filters. Check ducts for obstructions and inspect the blower motor.

Troubleshooting Steps

1. Check the Thermostat:

   • Ensure the thermostat is set to the correct mode and temperature. Replace batteries if it’s not functioning properly.

2. Inspect the Power Supply:

   • RV furnaces typically rely on 12V power. Test the battery voltage and ensure your RV’s power system is working correctly.

3. Verify Propane Flow:

   • Check that propane tanks are full and the valves are open. Inspect the propane regulator for leaks or malfunctions.

4. Inspect Coleman AC Wiring:

   • If you have a Coleman AC unit, note that the power wire for the furnace comes from the AC control box. Coleman AC units are wired directly through the control box to the furnace, which can complicate troubleshooting. Ensure all connections in the AC control box are secure and functioning properly.

5. Clean the Furnace:

   • Turn off the furnace and clean the burner assembly, fan, and vents. Use compressed air to remove dust and debris.

6. Test the Ignition System:

   • If the furnace won’t ignite, inspect the igniter for dirt or wear. Replace if it’s faulty.

While many RV furnace issues can be resolved with basic troubleshooting, some require professional attention. If you’re dealing with gas leaks, extensive electrical problems, or a failing blower motor, it’s time to call the experts.

3. Use Quality Propane:

   • Ensure your propane is clean and free of contaminants to avoid clogging the system.

4. Monitor Battery Voltage:

   • Keep your RV’s 12V system in good condition to power the furnace effectively.
