Cold‑Weather LPG Safety Tips: How to Store & Use Patio Heater Gas Efficiently

When the temperature drops, LPG (liquefied petroleum gas) is the perfect fuel for keeping outdoor spaces warm and your BBQ sizzling. But winter changes how LPG behaves, and that means safety and efficiency matter more than ever. Here’s your complete guide to LPG safety tips for cold weather.

Why LPG Needs Extra Care in Winter

LPG is stored as liquid and vaporises to supply your heater or BBQ. In cold conditions, this process slows down—especially for butane.

Propane works reliably even at ‑40°C, making it ideal for patio heaters and BBQs outdoors.

Butane struggles below 0°C, so it’s better for indoor portable heaters where ventilation is adequate.

💡 Tip: For outdoor winter use, always choose propane.

Safe Storage Checklist

Proper storage prevents leaks and accidents:

✅ Store cylinders upright on a level surface in a well‑ventilated outdoor area.

✅ Keep away from heat sources, drains, and building openings.

✅ Never store indoors (cellars, garages, or basements).

✅ Inspect regulators and hoses regularly; replace if damaged or older than 5–10 years.

Efficient Use Tips

Position patio heaters in sheltered spots to reduce wind chill.

For BBQs, preheat longer and keep the lid closed to maintain heat.

❌ Turn off gas at the cylinder when not in use—don’t rely on appliance controls alone.

Troubleshooting Common Issues

❄️ Frost on regulator? Often normal in cold weather, but if the cylinder is on its side or overfilled, turn off and call an engineer.

🕯️ Weak flame? Check for leaks (soapy water test), hose damage, or regulator faults.

💧Butane not working outdoors? Switch to propane—it just performs better at low temperatures.

Safety Essentials

✅ Fit an audible CO alarm (BS EN 50291 compliant).

✅ Service heaters annually with a Gas Safe registered engineer.

✅ Never move heaters while lit; always shut off at the cylinder first.
