What size propane tank is recommended for gas logs?

For gas logs, a 20-pound propane tank is typically recommended for smaller installations, while larger systems may require a 100-pound tank or even a 500-gallon tank for more extensive use. The size you choose depends on the frequency of use and the BTU output of your gas logs. It's important to consider your specific heating needs and consult with a professional to determine the best tank size for your setup.
