Air recuperation

The more we insulate buildings, the more tight and beer insulated double-glazed, triple-glazed, argon-filled windows we use, the more we fill in any existing cracks in the walls of the house, the more we are in principle closing ourselves into a "plastic" submarine that stops breathing. Therefore, if we close ourselves into such a submarine, all the air we breathe out, all the humidity from showering, cooking, stays with us at home. Yes, you can open a window and air out.... But why did you buy expensive triple-glazed windows with argon filling if the only adequate air exchange is micro ventilation? You may have bought ordinary double-glazed windows.

12 years ago, when we started in this business we tended to say: „recuperation, recuperation, what it really is? Big pipes, we carry air in an assembly van.“ We still didn't understand why such a segment can be so supported and pushed through by legislation. It was only over time, and even are buying a CO2 - carbon dioxide meter, that we understood how important the air recuperation can be.

Personally, I would venture to admit that up to a half of marital arguments at home roots from the airless environment. Give it a try by buying a CO2 meter, put it in the middle of your living room, air out the space and close up the window. Afterwards track the progress of rising CO2 concentration and O2 depletion in the room. You will notice that you start ge;ng tired and sleepy at 1000ppm of concentration which corresponds to the scenario of 2 persons staying and sharing one room for up to 1-2 hours. In the concentration of 1500ppm and higher you can experience headache and nervousness.

Standardly then occurs the fact that instead of airing out and thus dealing with the root of our discomfort we get easily triggered by the tiniest thing that irritates us on our loved one.

Think of an occasion when you walked into the room occupied by numerous people, and you were trying to convince them to open the window. You cannot evaluate the quality of air while dwelling in the given space. And this common occurrence of all new constructions, renovations, insulation's and windows replacement when the air recuperation is not installed along with it. In the past this role was played by the old windows that have been replaced by the new ones.

We offer a design, project and handling of the state subsidy for either for the central air recuperation – suitable for new buildings – or for to decentralize ones – suitable for the places where new air distribution systems cannot be implemented.

In the section of realization (on this page) you can see the detailed installation process.

Either air distribution, with a pipe dimension of at least 100 mm in diameter, or hot water tubes drawn in the floor are difficult to be worked on in an existing house unless you want to move out for a certain period of time. And therefore we recommend installing of air recuperation before photovoltaic system itself.

Of course, air recuperation also saves energy; the blown used air preheats the cold fresh one that is drawn into. There is an energy saving - a primary energy saving according to which EPCs are now issued for new buildings and for which the air recuperation is now required even before get planning permission.

However, as a main advantage of we can see the healthy living environment where we can live rather than only energy savings.
