When dealing with propane gas exchange tanks, understanding the amount you’re getting is essential.
The most common size for exchange tanks is 20 pounds (approximately 4.7 gallons). This size is typically used for grills, portable heaters, and small appliances.
When you exchange an empty tank for a full one at a retailer or gas station, you’ll receive a tank that is already filled to its maximum capacity.
Note that the actual amount of gas in an exchange tank may vary slightly depending on factors such as temperature and pressure. These tanks are designed to be filled to about 80-85% of their total capacity to allow for expansion and fluctuations in temperature. This means that a 20-pound exchange tank may have approximately 16-17 pounds of gas in it.
To know the exact amount remaining in an exchange tank, you can use a gauge or a weight scale. Gauges are typically attached to the tank and provide an indication of the gas level. Alternatively, you can weigh the tank using a scale and refer to a weight chart to estimate the amount remaining based on the tank’s weight.
Propane exchange tanks are convenient for their ease of use and quick replacement. While the specific amount in an exchange tank may vary slightly, the tanks are filled to the appropriate level to ensure you have enough for your needs.
