Overall About Propane RV Refrigerators
Let’s have an overview of how does a propane refrigerator work and how long does propane last in an RV fridge?
RV Refrigerators are often referred to as Absorption Refrigerators. These refrigerators absorb many kinds of liquids, such as water and gaseous substances like ammonia and hydrogen gas.
By doing so, the refrigerator heats up the absorbed matter. This causes it to evaporate, allowing the cold vapor to traverse through the fridge, making it cooler in the process.
Such a camper appliance works by running an RV fridge on propane. It is recommended to have a battery power of at least 10.5 volts so the fridge can ignite and run smoothly.
An RV fridge can also be powered by a battery. But do keep in mind that if a 12-volt battery solely powers it it can only keep your fridge running for about 8 hours.
How long will an RV fridge run on propane? The standard propane-powered fridge, which measures around 4 to 12 cubic feet, can go on for a few weeks.
This is also dependent on the size of your fridge. If one is to use a 20-pound tank full of propane, your refrigerator’s power can last a month.
How Much Propane Does an RV Refrigerator Use?
Now let’s answer the question, how much propane does an RV use? The standard 10 Cubic Feet RV refrigerator uses at least 1.5 lbs of propane per day.
That would take up around 1,400 BTUs per hour. It is almost close to the Dometic RV fridge’s propane amount, which is 1,500 BTUs per hour.
The BTU, or British thermal unit, is the amount of heat being measured from power and fuel sources. Each gallon of propane contains 91,500 BTUs.
One gallon of propane can power your fridge for about 61 hours. That’s about 2.54 days of fridge power if you do the math.
For different propane tank sizes, let us identify and calculate how much propane does a camper fridge use.
- 20 lb Propane Tank
Normally, there is about 4.6 gallons propane in a standard 20 lb tank or grill cylinder. These gallons weigh 37 lbs when filled up. This can give your fridge enough juice for around 11 to 12 days if it runs 24 hours per day.
- 30 lb Propane Tank
A 30 lb propane tank holds up to 7 gallons of propane. A full tank of this size can weigh 55 lbs and can power your 8 cubic feet fridge that uses 1500 BTUs per hour for at least 18 days.
- 100 lb Propane Tank
If you have a larger RV, then this kind of propane tank would suit your needs. Although a 40 lb propane tank could do the trick, a 100 lb propane tank can hold up to 19.46 gallons of propane and can run your camper fridge for at least 59 days.
It is also important to note that the RV fridge propane usage will depend on its size, quality, and maintenance measures.
A well-maintained fridge will be more efficient and can help keep your food items preserved. It also prevents excessive propane usage and overheating.
Tips to Reduce the Amount of Propane
Here are some of the helpful tips you can acquire to reduce the amount of propane usage for your RV fridge.
1. Regular Maintenance
You may do a visual check on your fridge for any signs of worn-out parts, leakage, or corroded components and have them immediately replaced or fixed. Proper fridge maintenance also includes regular defrosting.
2. Level Your Fridge
To maintain your camper fridge’s quality make sure to level your fridge at least 3 degrees on each side and 6 degrees for the front and rear portions.
You may use automatic levelers such as electric and hydraulic ones for your RV. If your RV happens to be improperly leveled, then your fridge can take in more propane which may damage it due to overheating.
3. Proper Ventilation
Let the air circulate and pass through the vents of your fridge. So it is important that food items or ice will not block the vents. Pack your items wisely.
4. Don’t Overcrowd Items in the Fridge
Too much food and items in your refrigerator can hinder its cooling process. The air becomes trapped inside the refrigerator’s remaining spaces thus making it utilize more power.
5. Keep Your Fridge Away From Direct Sunlight
Make sure that when you are parking your RV, the sunlight does not directly affect your fridge. Fridges in general that are directly placed in sunlight can cause more power consumption. You may use awnings or look for shaded areas if that is the case.
