Tips and advice

Motor Noise
A powerful motor provides higher extraction capacity, but also generates more noise. You can reduce the noise by lowering the motor speed. This will also reduce the airflow, but the lowest setting is sufficient most of the time.

Air Noise and Duct Noise
Moving air creates noise. Just like the sound of wind, noise occurs when air encounters resistance. The straighter your ducting installation is — with as few bends and turns as possible — and the larger the ducts the air passes through, the lower the noise level will be.

How to Avoid Fingerprints on Elegant Steel Surfaces
The trend of stainless steel is elegant, but also slightly impractical. Even the smallest touch leaves highly visible fingerprints on steel surfaces.

This drawback can be completely avoided by choosing a remote control, available as standard or optional equipment for several THERMEX range hoods.

This way, you avoid any physical contact and enjoy a fingerprint-free range hood.

Save Energy by Using Your Range Hood Correctly
You can achieve significant energy savings by using your range hood properly. A hood running at the highest setting can consume up to one and a half times more energy than on the lowest setting. The highest setting is typically only necessary when cooking food that produces strong odors, steam, or smoke.

Start the range hood five minutes before you begin cooking or frying. This helps create the necessary negative pressure in the kitchen, meaning the motor does not need to operate at maximum power.

A lower and more targeted extraction level also reduces heating costs, as less of the warm air in your kitchen is removed and replaced.

In the Case of Ceiling-Integrated Models
It is important to note that the distance from the cooking zone to the filter surface is greater than usual. This type of model is typically equipped with perimeter extraction, which enhances efficiency.

THERMEX recommends that the distance between the cooktop and the filter does not exceed 3 meters.

Optimal Installation Height
THERMEX recommends installing your range hood at a height of 500–700 mm above your cooktop. However, always ensure compliance with applicable regulations and the specifications for both the cooktop and the range hood.

Reduce Unwanted Noise
THERMEX always recommends using condensation- and sound-insulated ducting throughout the entire installation. This helps reduce unwanted noise and moisture.

If you have purchased a product with an external motor, it is recommended to install a silencer between the range hood and the motor. The silencer further reduces the noise generated by airflow through the system.

Clean Grease Filters Perform Best
Grease filters should be kept as clean as possible to maintain optimal performance. Depending on how often and what type of food you cook, you should expect to clean your metal filters approximately once a month — which is still much easier than a full kitchen clean.

Always follow the instructions provided for your specific product.

Avoid Loss of Extraction Performance
As far as possible, the use of 90° bends should be minimized. A single 90° bend causes the same loss of extraction performance as one meter of ducting. Always keep ducts and pipes as short as possible. The longer the installation, the greater the pressure loss — resulting in reduced extraction performance.

Always use the largest possible duct diameter. If your range hood or motor is designed for Ø160 mm, you should use at least a Ø160 mm duct. Reducing the diameter by just one size can decrease performance by up to 66%.

Duct Customization
Let Thermex tailor the ducting to fit your kitchen perfectly. For a wide range of models, the duct can be customized in both length and design — it can be shortened, extended, or angled, for example to suit sloped ceilings.

If additional length is required, an extended duct or an extension adapter can be used. Please note that custom modifications are subject to an additional charge.
