Troubleshooting Issues
8. Gas Expansion and Contraction
As temperatures fluctuate, propane gas expands and contracts. During hot weather, the gas expands, increasing pressure in the cylinder. If the cylinder is filled to capacity at high temperatures, it may become overfilled when temperatures cool, potentially leading to a dangerous situation. To avoid this, do not fill cylinders to capacity when temperatures are high, leaving a small headspace for expansion.
Conversely, in cold weather, propane gas contracts, reducing pressure in the cylinder. If a cylinder is filled based on weight in cold weather, it may be underfilled once temperatures rise, resulting in insufficient propane for your appliances.
Tips for Mitigating Gas Expansion and Contraction Issues:
| Temperature Range | Cylinder Filling Capacity |
|---|---|
| Above 85°F (29°C) | Fill to 80% capacity |
| 60-85°F (16-29°C) | Fill to 90% capacity |
| Below 60°F (16°C) | Fill to 80% capacity and re-weigh once temperatures stabilize |
By adhering to these filling guidelines based on temperature, you can ensure the safe and appropriate filling of your propane cylinders throughout all seasons.
