What ventilation system do I have?
Posted on 4-4-2022 by Felix Dijkmeijer

Improperly ventilating a home can create an unhealthy living environment and therefore result in health problems. It is interesting to know which ventilation system your home or office has, so that you can use it correctly. It could be that the incorrect use of a ventilation system will result in unnecessary costs or a deterioration of the living environment. Below we explain which types of ventilation systems can be present in your home or office. Do you want to buy a ventilation system? Then first read more about the types of ventilation systems available at Ventilatieland.

Mechanical ventilation with natural air supply (MEV)

Mechanical ventilation with natural air supply through ventilation grilles, cracks and open doors or windows, is the most common ventilation system in contemporary homes. Mechanical ventilation makes use of a central extraction fan that extracts the air in the house, while clean air is drawn in through natural ventilation. Usually this natural ventilation takes place by means of placed ventilation grilles. From the central ventilation unit, ventilation ducts can be pulled into different rooms, so that there is sufficient ventilation in all rooms in the house, such as bathroom, bedroom and living room. Ventilation valves are placed in these rooms to ensure proper air extraction in the house.

With the most common mechanical fans, such as Itho, Zehnder Stork, Orcon, Duco and Vasco home fans, the control can be controlled by different controls such as a wireless transmitter or a wired three position switch. Of course it is also possible to connect multiple controls to one ventilation system. For example, it is possible to connect a three position switch in the kitchen as well as in the bathroom.

Mechanical ventilation by means of a MVHR unit

When you ventilate with a MVHR unit you use heat recovery and balance ventilation. These complex and modern ventilation systems guarantee a healthy environment in your home and provide a clearly visible energy saving. With a MVHR unit, fresh air is sucked in mechanically, so there is no need for ventilation grilles in the facades. The MVHR unit consists of two separate ventilators, one to extract polluted air to the outside, the other to suck fresh air into the house. Because these two airflows take place along the bay window, the heat of the exhaust air can be used to heat the incoming fresh air.

In a society and political landscape where energy-neutral and environmentally conscious living plays an important role, it is almost impossible to imagine today's society without a MVHR system. At Ventilatieland you can find MVHR units of the well-known A-brands Brink, Itho, Zehnder Stork, Orcon, Duco and Vasco.

Demand-driven ventilation

With demand-driven ventilation, ventilation is only provided when necessary. With the help of a CO2 meter, the indoor air in the house is measured on the present CO2 content. When this CO2 content is so high that it can be harmful to health (symptoms: fatigue, headaches, chronic colds), these high values are passed on to the demand-driven ventilation system. Because of these high values, the ventilator knows that extra ventilation is needed in the room in which the high CO2 concentration was measured.

By using demand-driven ventilation you not only pay attention to a healthy indoor climate, but you can also save a lot of money and energy. Because you only ventilate extra when needed, no more energy will be wasted on unnecessary ventilation. For more information about demand-driven ventilation you can consult our blog.

The CO2-controlled fans can be found here.

Natural ventilation

Natural ventilation is ventilation that takes place without the mechanical help of a ventilation system. In this case, the dwelling is ventilated by existing ventilation grilles, flap grilles and cracks in a poorly insulated dwelling. Open doors and windows are also part of natural ventilation. With natural ventilation, a contribution is made to a healthy indoor climate, but this is only for a short period of time. Half an hour after closing windows or ventilation grilles, there is very little fresh air that has been brought in by natural ventilation. An enormous amount of energy and heat is also wasted, which is a shame of course. A one-off investment in a mechanical ventilation system can therefore generate a lot of money annually by saving on energy costs.

Mechanical ventilation in certain rooms

Examples of local ventilation include a bathroom fan in the bathroom or an extractor hood in the kitchen. Tube fans are also an example of local ventilation. By using local ventilation, rooms where extra ventilation is desired can be ventilated optimally. There is no need for a central ventilation system. A bathroom fan with a ventilation duct and ventilation grille on the facade is sufficient, the exhaust air can easily leave the house in this way.
