In modern homes, air quality plays a key role in the comfort and health of residents. Controlled ventilation is essential, especially in well-insulated homes, which are becoming increasingly common as a result of energy-efficient renovations and the construction of low-energy houses. Without adequate ventilation, moisture problems, mold growth, and poor air quality can occur. A ventilation system ensures continuous air exchange, which not only guarantees a supply of fresh air, but also removes pollutants and CO2 from the living spaces.
In this article, we focus on decentralized ventilation systems, which are a flexible and energy-efficient solution for modern residential buildings. Unlike central ventilation systems, which usually require a complex network of air ducts, decentralized systems work on a room-by-room basis and are often easier to install—a significant advantage for tradespeople and installers.
In single-family homes and apartment buildings, ventilation systems make a significant contribution to a healthy indoor climate and efficient energy use. Decentralized ventilation systems prove to be a particularly intelligent solution in this regard.
Decentralized ventilation systems are particularly suitable for buildings in which either no central duct system has been planned or retrofitting is required. These systems are installed in individual rooms or zones of the house and enable targeted air exchange where it is actually needed. This makes them a flexible solution that can be used in both new and existing buildings.
Installers particularly appreciate the easy installation and maintenance of decentralized ventilation systems. Thanks to their modular design and flexible application options, these systems can be installed quickly and easily in different types of buildings. While central ventilation systems require more complex planning and the installation of air ducts throughout the building, decentralized units can be installed directly into the exterior walls of the rooms. This often means considerable cost and time savings during installation and less interference with the building structure.
Decentralized ventilation systems also offer high energy efficiency, as they are only active where ventilation is actually needed. This results in a targeted and resource-saving air supply, both in single-family homes and in apartment buildings. Decentralized solutions are therefore particularly well suited for use in renovation projects.
The installation of decentralized ventilation systems requires specific know-how and precise planning to ensure optimal functionality and efficiency. Thanks to their versatility and high adaptability to different building types, decentralized ventilation systems are a smart and future-oriented solution for healthy and energy-efficient ventilation in residential buildings.
Central ventilation systems offer the advantage of being able to ventilate all rooms in a house simultaneously via a central duct system. However, the installation of a central system is significantly more complex and expensive. It also requires regular maintenance, in particular cleaning of the ducts, to ensure air quality.
In comparison, decentralized ventilation systems are easier and quicker to install. They offer targeted ventilation, are more flexible in their application, and are often less expensive to maintain. Decentralized systems are the better choice, especially in existing buildings or for retrofits. In many cases, customers will opt for a decentralized system because of its flexibility and lower costs.
For installers themselves, the cost and time savings are a decisive factor in choosing a decentralized system. Thanks to the simpler installation without complex duct systems, the installation can often be completed in less time, which reduces labor costs. Retrofitting in existing buildings is also less complicated, as only selective interventions in the building envelope are necessary.
In the long term, homeowners benefit from lower operating costs, especially with systems that feature heat recovery. Decentralized ventilation systems therefore offer numerous advantages for both installers and homeowners.
Decentralized ventilation systems without heat recovery
Not all decentralized ventilation systems are equipped with heat recovery. Ventilation systems without heat recovery are cheaper to purchase and easier to maintain. They are particularly suitable for rooms where continuous ventilation is important but heat loss is not a major issue—for example, in less frequently used rooms such as basements, storage rooms, or garages. At the same time, these systems ensure the officially required air exchange rates.
For tradespeople and installers, these systems offer the advantage of quick and inexpensive installation. In many cases, they can be a good alternative if heating costs are not a primary concern for the building operator or if the rooms do not need to be heated continuously.
Decentralized ventilation systems with heat recovery
For rooms where high energy efficiency is important, decentralized ventilation systems with heat recovery offer the optimal solution. These systems use the heat from the exhaust air to preheat the incoming fresh air, which reduces energy consumption and heating costs. These systems are a sensible investment, especially in living spaces that are heated a lot, such as living rooms, bedrooms, and kitchens.
For tradespeople, installing such systems is often only slightly more complex than installing systems without heat recovery. However, the long-term benefit for homeowners lies in lower operating costs and improved energy efficiency.
As with any technical installation, there are challenges to consider when installing decentralized ventilation systems. A common mistake is not correctly matching the system performance to the room size and ventilation requirements. Choosing the wrong ventilation system can lead to insufficient air exchange or drafts (learn more about common mistakes when installing ventilation solutions).
The ventilation system should always be carefully tailored to the specific requirements of the house. Malfunctions can occur if the air flow is not distributed correctly or if the ventilation system does not supply the required amount of air. It is also important to provide residents with basic training in how to use the ventilation system. Incorrect operation can lead to performance drops or cause damage.
Integrating ventilation systems into existing buildings can also be a challenge. The structural conditions must be carefully examined to ensure that the ventilation system can be installed optimally.

Another potential stumbling block is sound insulation. It is important to choose ventilation systems with high sound insulation to ensure that no outside noise penetrates the living space. It is also crucial to rely on high-quality systems such as those from Ventomaxx to ensure quiet operation of the fans.
Solutions with high-quality products help to minimize many of these problems. Our decentralized ventilation systems are not only energy-efficient, but also designed to operate quietly while ensuring optimal air circulation. When choosing a system, it is therefore crucial to pay attention to quality and reliability in order to avoid long-term problems.
When it comes to ventilation systems for residential buildings, planners and builders are often faced with the question of whether to opt for decentralized or central ventilation systems. Both approaches have their advantages and disadvantages and are suitable for different requirements.
Decentralized ventilation systems offer the advantage of being able to ventilate individual rooms or areas independently of each other. This is particularly practical in single-family homes or small apartments, where there are different requirements for the indoor climate. Individual control of the air supply and exhaust allows residents to adjust the ventilation to suit their needs.
Central ventilation systems, on the other hand, are designed for larger buildings. They offer central control and can regulate the indoor climate throughout the entire building. These systems are particularly well suited for even air distribution and can be more efficient when it comes to ventilating large areas.
When deciding between decentralized and central ventilation systems, various factors should be taken into account. The size of the building, the individual room requirements of the residents, and the structural conditions play an important role. It is advisable to seek advice from experts in order to find the optimal solution for the respective residential project. We are happy to advise you on this.
Overall, both decentralized and centralized ventilation systems offer effective ways to improve the indoor climate in residential buildings and ensure fresh and healthy air quality. Each variant has its specific strengths, which come into play depending on the individual requirements and circumstances of the construction project.
