Quick Answer
A 20-pound propane tank is a good starting point for RV refrigerators with lower power demands, while a 30-pound tank is more suitable for larger or more power-hungry units.
Choosing the Right Propane Tank Size
When selecting a propane tank for your RV refrigerator, consider the appliance’s power demand. A general rule of thumb is to choose a tank with a minimum of 1/4 gallon capacity for every 1,000 BTUs of refrigerator power. For example, a 1,000 BTU refrigerator would require a 1/4 gallon tank, while a 2,000 BTU model would need a 1/2 gallon tank.
Calculating Propane Demand Based on Refrigerator Size
To determine the ideal propane tank size for your RV refrigerator, calculate the appliance’s power demand in BTUs. Typical refrigerator sizes and their corresponding BTU ratings are:
- Small/ compact refrigerators (1-2 cu. ft.): 600-1,200 BTUs
- Medium refrigerators (2-3 cu. ft.): 1,200-1,800 BTUs
- Large refrigerators (3-4 cu. ft.): 1,800-2,400 BTUs
- Extra-large refrigerators (4-6 cu. ft.): 2,400-3,000 BTUs
Additional Considerations for Propane Tank Size
In addition to the refrigerator’s power demand, consider other factors when selecting a propane tank size. A larger tank can provide a safety buffer in case of increased power consumption or unexpected usage. However, oversized tanks can be heavy and occupy valuable storage space. It’s essential to strike a balance between having sufficient propane supply and minimizing weight and storage needs.
For example, if you have a large refrigerator with a 2,400 BTU rating, a 30-pound tank (approximately 1.3 gallons) would provide a suitable balance between propane supply and weight/storage considerations.
