Energy Efficiency Tips for Range Hoods 

June 25,2024

Ensuring energy efficiency in the kitchen is crucial for both environmental sustainability and cost savings. One key area often overlooked is the range hood, an essential appliance for maintaining air quality and reducing grease build-up. In this article, we will delve into detailed and actionable tips to enhance the energy efficiency of your range hood.

Understanding Range Hood Efficiency

A range hood’s primary function is to remove airborne grease, combustion products, fumes, smoke, odours, heat, and steam from the air by evacuation and filtration. The efficiency of a range hood is determined by its airflow capacity (measured in cubic feet per minute, or CFM), energy consumption, and the effectiveness of its filtration system.

Choose the Right Size and Type

Selecting the appropriate size and type of range hood is the first step towards energy efficiency. The size of the hood should match the size of your cooktop. A hood that is too small won’t effectively capture all the pollutants. In contrast, an oversized hood might consume more energy than necessary.

  • Under-Cabinet Hoods: These are typically installed under kitchen cabinets and are ideal for smaller kitchens. They are compact and efficient, but ensure your chosen model has a high CFM rating.
  • Wall-Mounted Hoods: These are installed on the wall above the cooktop and are suitable for larger kitchens. They generally have higher CFM ratings and can cover larger cooking areas.
  • Island Hoods: Installed above kitchen islands, these hoods are generally more potent due to their need to cover a broader area.

Optimal Ventilation Rate

The optimal ventilation rate for a range hood is between 100 to 300 CFM for most home kitchens. This range ensures the effective removal of pollutants without excessive energy consumption. A higher CFM rating may be necessary for high-output cooktops or frequent cooking.

Energy-Efficient Features

Modern range hoods come with various features designed to improve energy efficiency. Here are some key features to look for:

Variable Fan Speeds

Range hoods with variable fan speeds allow you to adjust the airflow according to your cooking needs. Using the highest setting only when necessary and lower settings for lighter cooking tasks can significantly reduce energy consumption.

LED Lighting

LED lights consume less energy and last longer than traditional incandescent or halogen bulbs. Opt for range hoods with LED lighting to enhance energy efficiency and visibility in your cooking area.

Automatic Shut-off and Delay Timer

An automatic shut-off feature turns off the hood after a set period, ensuring it does not run longer than necessary. Delay timers can keep the hood running for a few minutes after cooking to clear residual fumes, then automatically switch off, which saves energy compared to manual operation.

Optimising Kitchen Ventilation

Beyond the range hood itself, optimising overall kitchen ventilation can enhance energy efficiency. Here are some tips:

Use Natural Ventilation

Natural ventilation is used by opening windows and doors to complement the range hood’s operation whenever possible. This can reduce the need for the hood to run at high speeds, saving energy.

Integrate with Smart Home Systems

Integrating your range hood with a smart home system can provide better control and monitoring of its usage. Intelligent systems can automate the hood operation based on cooking activity, ensuring it runs only when necessary and at optimal speeds.

Proper Cooking Techniques

Adopting energy-efficient cooking techniques can also contribute to overall kitchen energy savings. For instance, using lids on pots and pans to contain heat can reduce the need for higher hood settings. Similarly, cooking on the back burner allows the range hood to capture fumes more effectively.


Improving the energy efficiency of your range hood involves selecting a suitable model and using energy-efficient features. Following these Do, All Appliances comprehensive tips ensure that your range hood operates efficiently, reducing energy consumption and enhancing kitchen air quality. Embrace these practices to lower your energy bills and contribute to a more sustainable environment.
