FAQs on Controlled Mechanical Ventilation

Have you ever heard of controlled mechanical ventilation but don’t know what it is? It’s an electrical device that both renews the indoor air in a home and limits heat loss. To know more about it, read this article.

What Is Controlled Mechanical Ventilation?

Controlled mechanical ventilation or CMV is a ventilation system like no other. It consists of four elements: a motor, a network of ducts (2 for a double-flow CMV), air inlets, and air outlets.

This ventilation system can be installed in any house room, especially in humid rooms: toilets, bathrooms, kitchens, etc. The installation of the VMC is recommended if your building includes a storeroom.

What Are the Main Advantages of Controlled Mechanical Ventilation?

Controlled mechanical ventilation has many advantages for the occupants of a house.

Just like mechanical ventilation by insufflation, CMV makes it possible to improve the air quality inside a house. Therefore, you can benefit from fresh and healthy air because bad odors will be evacuated outside your home. The same is true for solvents and pollutants in the air.

Moreover, installing the controlled mechanical ventilation allows for realizing a vital energy savings. As a result, your home will no longer be subject to energy losses.

Apart from that, installing this ventilation system will allow you to comply with the thermal regulations in force. Indeed, since the promulgation of the RT 2012, new homes must be equipped with a CMV.

What Are the Different Types of Controlled Mechanical Ventilation?

There are currently two types of controlled mechanical ventilation:

Single flow mechanical ventilation: if you have a tight budget, opt for single flow mechanical ventilation. Indeed, it is much more accessible in price than the double-flow one. Moreover, its power consumption is very low, which will allow you to reduce your energy bill. In addition, this device is easy to maintain and takes up little space.

Double flow CMV: Double flow CMV offers better air quality than single flow CMV. Indeed, its capacity to filter the polluted air inside is remarkable. Moreover, the air it diffuses is warmer, allowing you to stay away from the cold during the winter. However, this type of ventilation has many drawbacks. Indeed, it requires a lot of maintenance, including regular cleaning. In addition, it is very noisy and cumbersome. Apart from that, its cost is twice as high as that of the single-flow ventilation system.

How Much Does It Cost To Install a Controlled Mechanical Ventilation?

The cost of installing a controlled mechanical ventilation system varies according to the chosen ventilation model, the desired efficiency rate, the number of rooms to be treated, and the installation’s complexity.

To install a single-flow ventilation system, plan on a budget of 600 to 1,700 euros. On the other hand, to install a double-flow CMV, count between 4 800 and 10 800 euros.
