Cooking on gas: what it means for the air in your kitchen
A gas cooktop burns gas inside your home. Here's what that puts into the air, and simple ways to keep your kitchen air fresher.
What's in the air when you cook on gas
A gas flame is combustion, like a small fire. Along with heat, it gives off gases such as nitrogen dioxide and carbon monoxide, plus fine particles from the cooking itself. In a kitchen, those mix straight into the air you breathe.
Why ventilation matters
- A rangehood ducted to the outside removes fumes at the source. Recirculating hoods filter grease but don't take gases outside.
- Use the back burners when you can: most rangehoods capture more from there.
- Open a window while cooking if you don't have a ducted rangehood.
What induction changes
An induction cooktop heats the pan with a magnetic field, so there's no flame and no combustion gases. It's also quick, easy to clean and runs on electricity, which your solar can supply during the day.
Is it worth switching?
- Switching usually means a new cooktop, a quick electrical check and sometimes new pans (a magnet should stick to the base).
- If you're planning to leave gas altogether, induction is a common place to start, alongside heat-pump hot water.
- If you're already having electrical work done, such as solar, doing it at the same time can save a visit.
Revo's tipTurn the rangehood on before you start cooking and leave it running for a few minutes after. It's the easiest free fix there is.
