Fuel use
| Fuel | Half load | Full load |
|---|---|---|
| Propane | 2.39 gal/hr | 3.95 gal/hr |
| Natural gas | 197.8 ft³/hr | 321.1 ft³/hr |
On propane, a 500-gallon tank filled to 80% holds about 400 gallons. That runs the Champion 26kW Whole House (200A Switch, fleX) for about 167 hours (7.0 days) nonstop at half load, or about 101 hours (4.2 days) at full load. See how much propane a generator uses for other tank sizes.
On natural gas, the gas line and meter have to deliver the full-load figure, 321.1 ft³/hr, even if the generator rarely runs that hard. Installers size the pipe to it.
