What makes Renson ventilation different?
What makes Renson ventilation different?
Renson has been a leading Belgian manufacturer of ventilation systems for over 50 years. The company understands better than anyone how important a healthy indoor climate is, and that every building breathes differently. Whether you have a compact studio, a spacious new-build home, or a busy office, Renson offers a solution that truly fits.
The range includes natural supply vents, mechanical ventilation C+ that centrally extracts air, balanced ventilation D+ with heat recovery, and decentralised systems such as Renson Waves for renovation. Each system caters to a different type of home and budget.
What sets Renson apart? The smart design, the quiet operation, and the thoughtful control via an app or a simple switch. Moreover, the systems are modular, so you can easily expand later on, for example with additional ventilation in the bathroom.
Nevertheless, choosing the right system is not a simple task. That's why we do things differently: we listen to your situation, explain clearly what is possible, and ensure that the installation runs smoothly, with a team in your region.

For every project
Renson ventilation in different situations
Whether it's a new build, a major renovation, or a small apartment: Renson has a suitable solution for every context. Here's how we work in practice.
New-build home
From the shell construction stage, we plan the optimal ventilation together with you and the contractor. Usually, a Renson D+ with heat recovery comes into its own best.
Renovation project
For existing homes, we avoid demolition work. A decentralised system like Renson Waves or a C+ with limited ductwork provides a solution without major renovation.
Apartment
Compact spaces require smart ventilation. Renson C+ is often the ideal choice with its automatic demand control and simple operation.
Business premises or office
We also advise on a healthy indoor climate for commercial spaces. We provide suitable Renson solutions, with extra attention to acoustics and energy consumption.
Frequently asked questions about Renson ventilation
How does the Renson ventilation system work?
Renson systems continuously provide fresh air. Models like the Healthbox 3.0 (C+) extract polluted air via sensors that react to humidity or CO2. The D+ system adds heat recovery, saving energy.What can happen if you don't maintain a Renson extraction system?
Without regular maintenance, dust and dirt accumulate in the filters and ducts. This reduces air extraction, increases energy consumption, and can lead to mould growth or health issues such as headaches and allergies.What are the best ventilation brands?
Renson, Zehnder, and Brink are among the top in Flanders. Renson stands out due to its Belgian roots, quiet operation, and extensive range, from grilles to advanced D+ systems. The best brand depends on your home and preferences.How do I install Renson ventilation?
Installing a Renson system requires technical knowledge and experience. It is not a DIY job: mistakes can lead to poor performance or damage. We ensure professional installation by certified professionals.How often should you maintain a Renson ventilation system?
For a C+ system, we recommend annual maintenance: cleaning or replacing filters and checking the motor. For D+ systems, every two years is often sufficient. Regular maintenance extends the lifespan and maintains efficiency.What is the difference between Renson C+ and D+?
C+ is a mechanical extraction system without heat recovery. It extracts polluted air and lets fresh air in through grilles. D+ is a balanced ventilation system that both extracts and supplies air, and recovers heat. D+ is more energy-efficient but more expensive to purchase.Can I clean Renson ventilation myself?
Small tasks like dusting valves and cleaning grilles you can do yourself. But for opening the unit, replacing filters, and checking the motor, a maintenance visit by a professional is necessary.How much does a Renson ventilation system cost on average?
The price varies greatly by type and home. A simple C+ system starts at around 1,500 euros (incl. installation), while an extensive D+ system with heat recovery quickly costs 5,000 to 8,000 euros. Request a custom quote for an exact price.
