When cooking with a gas hob, you're dealing with more than just tantalizing aromas and sizzling stir-fries. Gas combustion produces smoke, grease, carbon monoxide, and excess heat—all of which require effective ventilation. That’s where a high extraction rate cooker hood becomes essential, especially a 90cm model designed to match wider cooktops and provide broader coverage.
That's why choosing the right cooker hood is crucial for both kitchen air quality and safety.
Why Gas Hobs Require Powerful Cooker Hoods?
Unlike induction or electric cooktops, gas hobs produce open flames. This leads to:
- More intense cooking fumes
- Higher levels of grease and moisture
- Greater need for ventilation
- Combustion gases such as carbon monoxide (CO) and nitrogen dioxide (NO₂)
To effectively extract these pollutants and ensure proper air circulation, a cooker hood with a high extraction rate is non-negotiable. Standard hoods (around 300–400 m³/h) may fall short, especially during intensive cooking.
How Many CFM are Needed for Cooker Hoods for Gas Stoves?
For gas stoves, the recommended CFM (Cubic Feet per Minute) for cooker hoods is:
- Minimum: 100 CFM for every 10,000 BTUs of your gas stove’s total output
- Or, at least 300–400 CFM for light cooking
- Ideally: 500–600 CFM for regular or heavy cooking (e.g., frying, wok cooking)
Also, for a 90cm (36-inch) hood over a gas stove, a range between 500–600 CFM is generally recommended to ensure effective ventilation.
When installing a cooker hood above a gas hob, positioning matters just as much as performance. Mounting the hood too low can pose a safety risk, while placing it too high reduces its effectiveness in capturing smoke and grease.
So, How High Should a Cooker Hood Be Above a Gas Hob?
The ideal installation height is typically between 65 cm to 75 cm (25 to 30 inches) above the gas hob.
This range offers the best balance between safety, heat resistance, and extraction efficiency. Always check the manufacturer’s guidelines, as some high-powered models may allow for slightly higher placement.
