Balanced ventilation system

Heat recovery for durable comfort

Plenty of ventilation at all times to guarantee fresh indoor air without the slightest inconvenience: the secret of a balanced ventilation system is its heat exchanger. This device uses the heat of the air that's extracted to preheat the fresh outdoor air that's drawn in. The result: no draughts and lower energy costs. What more could you ask for?

What is a balanced ventilation system?

A balanced system is a central ventilation system that combines mechanical supply with mechanical, demand-driven extraction. The built-in heat exchanger turns this system into an energy-efficient solution. The 'balance' element of a balanced ventilation system refers to the perfect fine-tuning that's required to keep the system running optimally.

How does a balanced ventilation system work?

A balanced ventilation system combines mechanical supply and mechanical, demand-driven extraction with a heat exchanger. This integrated heat exchanger recovers the heat of the extracted, polluted indoor air and uses it to warm up the colder, fresh outdoor air. That way, the energy consumed by the continuous operation of this ventilation system is compensated for by significant savings on heating costs.

The importance of a ventilation system

On average, we spend 90% of our time indoors, and the air quality inside is often poorer than it is outside. Counterintuitive as that sounds, this problem is quick to solve using an effective and reliable mechanical ventilation system. Your ventilation system extracts polluted, humid air and replaces it with fresh outdoor air to guarantee a healthy indoor climate, all year round.

The benefits of a balanced ventilation system

With a balanced ventilation system, the level of ventilation is the same for your entire home. As a result, you can continue to breathe freely and healthily in all rooms, at all times of the day and night.

  • The outdoor air that's supplied is warmed up using the polluted indoor air that's extracted via a heat exchanger. This helps you save on the cost of heating your home.
  • Filters clean the outdoor air of pollen, dust and other pollutants that might otherwise be blown into your home.
  • This demand-driven system effectively and fully automatically regulates supply and extraction based on the current air quality.
  • No damp issues in your home.


Are there any downsides to a balanced ventilation system?

Compared to a demand-driven exhaust ventilation system, a balanced ventilation system involves fitting a significantly higher number of air ducts and requires more maintenance. For example, you'll need to clean and replace the filters in good time. Of course, you're guaranteed clean air in return. The low level of noise produced by the fans is another thing to consider, so make sure you request sound damping too.

Balanced ventilation system applications

Demand-driven ventilation and heat recovery make a balanced ventilation system a valuable addition to a whole range of projects.
We’ve listed the applications of a balanced system for you below.

Homes

Homes

A long soak in a hot bath, cooking up a feast or a good night's sleep? A balanced ventilation system drives up the airflow as soon as the air quality starts to drop.

Schools

Schools

Students and pupils can continue to breathe oxygen-rich and fresh air right up to the bell, without having to open any windows.

Apartments

Apartments

From shared spaces all the way to private apartments: a balanced ventilation system guarantees good air quality throughout the entire development.

Healthy indoor air is essential to be able to concentrate and work efficiently. Thorough ventilation system boosts productivity and creativity.

Renson's balanced ventilation system

With Endura Delta, Renson has a reliable balanced ventilation system in its range. Thanks to its unique demand-driven operation, Endura Delta immediately kicks into action when it spots humidity, CO2 or odours in the air. Integrated sensors constantly monitor the air quality based on these parameters. A balanced system starts ventilating more intensively only when one of these parameters rises to unacceptable levels. That way, a balanced ventilation system is not only effective, but energy-efficient too.

On top of that, Renson has added a heat exchanger to its Endura Delta so that the cold outdoor air that's supplied can be preheated using energy from the polluted indoor air that's extracted. The result is no draughts — for greater living comfort — and lower energy bills for your heating.

Discover Endura

Easy controls using the app

With the Endura Delta app, you're completely in control of your indoor air at all times. You can use the app to view the indoor air quality in real time and control the operation of your balanced ventilation system. On top of that, the app will send you a notification when the time has come to change the filters. Handy, right?

How to maintain a balanced ventilation system

Regular maintenance is required to guarantee the proper functioning of your balanced ventilation system over the long term. The filters need to be checked twice a year and replaced if necessary. On top of that, it's best to clean the heat exchanger every two years, and the air ducts every five years. You'll need to call in a professional to do so. Discover more about the maintenance of ventilation systems.

Renson: more than 50 years of experience in ventilation

Good ventilation has become an increasingly hot topic over the past few years — and that's also reflected in the specific regulations and obligations when you build or renovate a home. Renson has been putting its insights and dedicated knowhow in to practice for decades. For over 50 years, our team has been committed to healthy indoor air in your home.
