Defro Pure Warmth

Mechanical heat recovery – home energy saving.

Energy efficiency is a slogan inherent in modern construction, especially when it comes to ventilation. This type of installation is intended to remove harmful gases, odors and water vapor, as well as supply oxygen. One of the most effective solutions is the installation of recuperators, which allow mechanical air exchange while recovering heat. How do they work, what to pay attention to and where to use them? Let’s check!

What are recuperators?

The basis of the mechanism’s operation is the transfer of energy obtained from the used air (heat in winter, cold in summer) to be used to heat or cool fresh air. Thanks to the fact that they are equipped with appropriate filters, the fresh air is clean, free of smog, allergens, and sometimes even viruses or bacteria.

When choosing an installation, you should pay attention to two parameters – efficiency and available pressure. Please note that due to the interdependence, an increase in the required pressure results in a decrease in performance. A more accurate assessment should therefore be checked using a pressure-performance diagram. It is also worth paying attention to the operation of the system with different fan and filter settings. This will allow you to verify whether the performance necessary for the proper operation of the system is possible to obtain. Therefore, if you need detailed information and help in choosing the right installation, it is worth taking a look at the offer of the Defro brand, which has the most experience on the Polish market as a manufacturer of recuperators. You will find a full range of air handling units, including: here.

Mechanical ventilation – where is it required?

The efficiency of such ventilation should be adjustable. The effectiveness of this type of home installation should be at least 20 m3. According to the WT2021 standard, anyone who received a building permit after January 1, 2021 should comply with the new construction rules, which include:

  • Reduction of U (heat conductivity coefficient of structural elements) by insulating external walls, floors and roof.
  • Reduction of the Ep coefficient determining the premises’ annual demand for non-renewable energy necessary for heating, ventilation and cooling, as well as hot water preparation and lighting.
  • Using technologies such as heat recovery, heat pumps, solar panels or photovoltaic panels.

Due to the above requirements, the importance of heat recovery is increasing – it is a very effective method of reducing the Ep of a building.It is therefore worth considering the implementation of this type of installation, especially at the design stage. In this way, implementation costs are reduced and they will eliminate one of the most frequently mentioned disadvantages – electricity consumption. However, various cheaper solutions can be used, such as the lack of ventilation chimneys, no need to install windows typically needed for ventilation (e.g. in bathrooms), etc. The heating itself is also much cheaper – up to 40%.

Either way, heat recovery is now a fundamental element of every modern home. Skillfully implemented and planned, it will not only improve the quality of life, but will also reduce costs.
