"How long will it last?" is the most common gas question. The honest answer: it depends on what and how much you cook — but here are realistic figures for Kenyan households.
Realistic Burn Times
| Cylinder | 1–2 people, daily cooking | Family of 4, daily cooking | Heavy use (chapati, nyama, big pots) |
|---|---|---|---|
| 3kg | 2–3 weeks | ~1 week | Days |
| 6kg | 3–4 weeks | 2–3 weeks | ~2 weeks |
| 13kg | 6–8 weeks | 4–6 weeks | 3–4 weeks |
| 50kg | — | — | Commercial scale |
What Burns Gas Faster
- Yellow/orange flames — inefficient combustion wastes gas. A healthy flame is blue. See why flames turn yellow and how to fix it.
- Oversized flames — a flame wider than the pot base wastes gas heating air.
- Slow foods — beans, githeri, matumbo and chapati marathons burn the most gas.
- Leaking regulators or hoses — even tiny leaks empty a cylinder over weeks. Check regularly with the soapy water test.
- Old meko burners — worn burner jets burn gas inefficiently.
How to Make Your Gas Last Longer
- Use lids on pots — cuts cooking time up to 30%.
- Match flame size to the pot — flame should just cover the base.
- Soak beans/githeri overnight — halves boiling time.
- Turn off the burner while flipping chapati between batches.
- Replace worn hoses and regulators — they're cheap, leaks are expensive.
- Keep burner jets clean — clogged jets give weak, wasteful flames.
The Warning Sign You Can't Ignore
If your cylinder suddenly empties much faster than usual, check for leaks immediately — that's the classic symptom of a valve or hose leak. Turn off the valve, ventilate, and read what to do when you smell gas.
Frequently Asked Questions
How many hours does 13kg of gas burn?
A medium burner flame consumes roughly 250–300g of gas per hour — a 13kg cylinder gives ~45–55 burner-hours total.
Why does my gas run out faster in cold months?
Cold water takes longer to boil, and you likely cook more hot meals — both increase consumption. That's normal, not a leak.
How do I check how much gas is left?
Weigh the cylinder and subtract the tare weight stamped on it — or use the hot-water-strip trick: pour warm water down the side and feel for the cold line where liquid gas sits. More methods in checking your gas level.
