Not all kitchens consume gas the same way.

Cooking Frequency

The more often you cook, the faster your gas is used.

Example: Cooking once daily vs three times daily can double or triple consumption.

Type of Cooking

Frying & baking → higher gas usage

Deep frying consumes significantly more gas due to prolonged heating.

Burner Efficiency

Old or poorly maintained burners waste gas.

Stat: Inefficient burners can increase consumption by 15–25%.

Cookware Used

Flat-bottom utensils = better heat transfer

Thin or curved vessels = heat loss

Cooking Habits

Simple habits like:

Leaving flame on unnecessarily
Not using lids

Can increase gas usage by 10–20%
