Probably everyone who has searched the Internet for information about ventilation has met examples of self-made ventilation equipment. Such «experts» ─ mainly the attendees of construction forums and Youtube-bloggers, promoting the idea of independent creation and installation of ventilation to the audience.

Why ventilation «with their own hands» ─ is not the best option?

The incorrect operation of the equipment

Factory equipment designed and built at a modern factory by a team of professionals (ventilation engineers, electrical engineers, service engineers, designers) meet international technical requirements and have the appropriate quality certificates. The launch of a new product on the market involves a long chain of processes:

• development of technical documentation;
• prototype development;
• testing of the prototype, laboratory and technological tests;
• introducing amendments to the prototype;
• certification.

Numerous tests on the ventilation equipment before putting it on sale guarantee the correct operation of the ventilation system. All materials used in the manufacture of ventilation equipment should be certified and safe for the consumer. In addition, the manufacturer always has a warranty. This means free professional service of the recuperator by the manufacturer.

Unbalanced air flows

The organization of ventilation begins with the project. The engineer-designer of ventilation systems calculates the necessary air exchange of rooms according to the provided plan. If we are talking about centralized ventilation, the designer calculates the necessary amount of related equipment (ducts, hemostats, adapters, etc.) and plans their location. The specialist makes design recommendations taking into account the specifics of the premises, which may include:

• the presence of gas or stove heating in the building;
• the presence of a fireplace;
• exhaust hood in the kitchen and bathroom;
• availability of basement or semi-basement rooms;
• the waterproofing of the house.

All PRANA recuperators have the advantage of tide over exhaust (by 8%). This creates additional pressure on the existing ventilation ducts in the building and prevents the phenomenon of reverse draught, which is dangerous to health and life. If makeshift ventilation is used, there is always a risk that a safe air exchange and air dilution will occur due to a lack of supply air. This threatens the consumer with incorrect operation of the extractor in the kitchen and bathroom, the spread of unpleasant smells from the ventilation ducts to the living areas.

Low energy efficiency

One of the risks of not professionally ventilating your home is significant heat loss during the heating period. If it is not difficult to provide an inflow of fresh air into the room, it is a much more difficult task to guarantee the preservation of a comfortable temperature in the room. The most important problem of homemade ventilation is that precious heat is thrown outdoors and the room is cooled. PRANA recuperators use a highly efficient copper heat exchanger to store heat (during heating) and coolness (during air conditioning). This material has long been known for its natural antiseptic properties and has high thermal conductivity. The heat exchanger has an inter-channel transfer of heat from the discharged tidal air. This ensures the flow of fresh, already heated air to the house and reduces energy costs (electricity, natural gas, solid fuel, etc.).
