What is the minimum size required for a propane tank used in an average home?

The minimum size required for a propane tank used in an average home is 120 gallons. This size is commonly recommended because it provides a sufficient amount of propane for typical household heating, cooking, and hot water needs. A 120-gallon tank can hold enough propane to adequately supply a home for several weeks, depending on usage patterns.

Choosing a tank that is too small could lead to running out of fuel during peak demands, such as winter months, potentially inconveniencing the homeowners with a lack of heating or hot water. While larger tanks, such as 150 or 200 gallons, may provide more capacity, 120 gallons is generally considered the standard minimum that balances the needs of average residential use with practical considerations.

It's important to note that regulations and specific household requirements may vary, so homeowners should consult local codes or a professional for tailored advice.
