Gas geysers are an efficient and cost-effective way to heat water, making them a popular choice in South African homes. If you’re using a 9kg gas cylinder (or any other size) to power your gas geyser, you might be wondering:
How long will it last?
The answer depends on factors such as geyser size, frequency of use, and temperature settings. This guide will help you estimate gas consumption and how long different gas cylinder sizes will last.
π₯ Gas Cylinder Sizes in South Africa
Before we dive into the calculations, here are the standard LPG gas cylinder sizes available in South Africa:
- 2kg Gas Cylinder
- 3kg Gas Cylinder
- 5kg Gas Cylinder
- 7kg Gas Cylinder
- 9kg Gas Cylinder
- 15kg Gas Cylinder
Now, letβs look at how long these cylinders will last when used with a gas geyser.
β³ How Long Will a Gas Cylinder Last on a Gas Geyser?
π Gas Consumption Rate of Gas Geysers
Gas geysers consume gas based on their flow rate (litres per minute – L/min):
- 6L/min geyser β ~0.8kg of gas per hour
- 10L/min geyser β ~1.5kg of gas per hour
- 16L/min geyser β ~2.5kg of gas per hour
π Estimated Gas Cylinder Duration
Gas Cylinder Size | 6L/min Geyser (~0.8kg/h) | 10L/min Geyser (~1.5kg/h) | 16L/min Geyser (~2.5kg/h) |
2kg | ~2.5 hours | ~1.3 hours | ~48 minutes |
3kg | ~3.75 hours | ~2 hours | ~1.2 hours |
5kg | ~6.25 hours | ~3.3 hours | ~2 hours |
7kg | ~8.75 hours | ~4.6 hours | ~2.8 hours |
9kg | ~11.25 hours | ~6 hours | ~3.6 hours |
15kg | ~18.75 hours | ~10 hours | ~6 hours |
π Daily Usage Example
If you use your 10L/min gas geyser for 30 minutes per day, it will consume about 0.75kg of gas daily.
- 2kg Cylinder β ~2.6 days
- 3kg Cylinder β ~4 days
- 5kg Cylinder β ~6.6 days
- 7kg Cylinder β ~9.3 days
- 9kg Cylinder β ~12 days
- 15kg Cylinder β ~20 days
π§ Tips to Make Your Gas Last Longer
β
Use a low-flow showerhead β Reduces water consumption, requiring less gas.
β
Adjust the temperature settings β Avoid overheating water unnecessarily.
β
Turn off the geyser when not in use β Prevent pilot flames from consuming gas.
β
Service your geyser regularly β A well-maintained geyser is more efficient.
