How Long Will A 20 lb Propane Tank Last?

A 20-pound propane tank will last for about 18-20 hours if used at a moderate rate. It assumes you are using it for activities such as grilling or heating and not running it at full power for an extended period. If you use your propane tank at a higher rate, it will run out faster. For example, if you are using it to run a space heater, it will only last for about 6 hours.

When it comes to using a 20 lb propane tank, the duration of use greatly depends on the level of usage and the specific appliance. For grilling, a 20 lb propane tank can last anywhere from 18-20 hours of grilling time at medium heat. This means that you could enjoy multiple barbecues and outdoor gatherings before needing a refill.

However, if the tank is used for heating purposes, such as with a patio heater or a portable camping heater, the duration will be significantly shorter. These devices have higher consumption rates compared to grills and may only last around 10-15 hours per tank. It’s important to keep in mind that cold weather conditions can also affect the duration as the tank’s liquid propane vaporizes slower in colder temperatures.

Ultimately, understanding your usage patterns and taking into account external factors such as weather will help you gauge how long your 20 lb propane tank will last. Being mindful of these considerations ensures that you have ample supply for your outdoor activities while avoiding unexpected interruptions due to running out of fuel.
