How Long Can a Whole Home Generator Run?

September 01, 2023

Multiple factors can affect how long your whole home generator runs. Here are a few things you should be aware of that can determine the run time of your whole home generator:

How long will my whole home generator’s fuel last?

Whole home generators are either run by tapping into your home’s natural gas line or off of an external fuel tank. If your whole home generator is tapped into a natural gas line, it will run as long as the gas line is on and undamaged. However, if you are using a propane or diesel tank to run your whole house generator the run time of your whole home generator is based on tank size. Based on past experience, for a 20 KW generator and a 500-gallon tank, the average run time of a generator is 4 – 9 days. For a 20 KW generator and a 1,000 gallon tank, the average run time of a generator is 8 – 16 days. However, there are many variables that will affect the run time of a generator.

What’s the lifespan of a whole home generator?

With a large tank or natural gas line running your whole home generator, the chances are incredibly low that you’ll run out of fuel during the time it is kicked on. However, how much usage can your whole home generator take? While this is dependent on the quality of the whole home generator you buy, top-of-the-line generators like Kohler Generators have a lifespan of between 1,500 to 3,000 hours.
