PRANA Heat Recovery Unit vs Other Ventilation Systems: What’s the Difference?

06/ 04/ 2026
  Today, there are many ventilation system options on the market, all tailored to different needs, budgets, and preferences. Each of these devices has its own purpose, advantages, and features. In this article, we’ll explore the differences between the PRANA heat recovery unit and other ventilation systems. How does the PRANA heat recovery unit work? PRANA is a supply and exhaust ventilation system with heat recovery. The heat recovery unit ensures a constant flow of fresh air into the room while simultaneously removing stale air, and the air streams do not mix with each other. The basic principle of the heat recovery unit is based on heat exchange between the air being removed from the room and the fresh air entering it. Thus, heat (or coolness) is not lost, which significantly reduces heating costs in winter or air conditioning costs in summer. So, let’s take a look at other types of ventilation solutions that are also widely used in buildings: 1) A supply air valve is a ventilation solution designed to bring fresh air into a room. This type of ventilation is one of the simplest. It is typically installed in living spaces directly into the wall or into the window frame. The operating principle of a supply valve differs from that of a heat recovery unit in that it provides only passive air intake due to pressure differences, without the ability to control air quality or the intensity of air exchange. Furthermore, a single supply valve is insufficient to ensure adequate air exchange; an exhaust system must also be installed in the room. In contrast, the PRANA heat recovery unit simultaneously provides both air supply and exhaust, creating a comfortable and controlled air exchange. 2) Exhaust systems are ventilation solutions whose primary function is to remove stale air from a room. They are most often installed in kitchens, restrooms, and bathrooms… Unlike a heat recovery unit, this type of ventilation does not supply fresh air but operates solely for exhaust. As a result, air enters the room uncontrollably through open windows or cracks, creating drafts and leading to heat loss. 3) A briser is a supply-type ventilation unit that delivers fresh air into a room and includes an option for electric air heating. These units do not remove exhaust air from the room, so they work effectively only when paired with an existing exhaust system. In contrast, a heat recovery unit does not require an exhaust system to operate. Furthermore, due to their electric heating, air coolers can lead to high energy consumption costs. PRANA heat recovery units, on the other hand, ensure heat retention through the principle of heat recovery based on a copper heat exchanger, making them more energy-efficient and economical to operate. Choosing ventilation equipment is always a personalized process. Each system has its own advantages and disadvantages depending on the expected results. However, if you want to create a comprehensive and controllable air exchange system with a focus on energy efficiency, PRANA is an excellent solution!
