Indoor air quality is crucial for a healthy and comfortable living environment. Heat recovery ventilation systems are among the most effective ways to ensure fresh air circulation while maintaining energy efficiency. When deciding on the best system, a common question arises: should you opt for a local or central heat recovery unit? This blog explores the differences, benefits, and suitability of each type.
Decentralized heat recovery units
Decentralized heat recovery units are ideal for smaller spaces such as bedrooms, bathrooms, or offices. They are easy to install and cost-effective, making them a popular choice for existing buildings.
Advantages of decentralized ventilation units:
- Simple installation without major construction.
- Energy efficiency by recovering heat from outgoing air.
- Suitable for areas needing precise ventilation control.
AHU systems
Central ventilation systems with heat recovery are designed for comprehensive air circulation in larger properties, ensuring consistent air quality throughout the entire space. They are particularly suitable for new builds or extensive renovations.
Advantages of AHU systems:
- Uniform ventilation across all rooms.
- Ability to handle larger air volumes.
- A long-term investment with higher energy efficiency.
Central systems require careful planning, as they involve ductwork installation and more significant structural modifications. Read more in our blog: .
In AHU systems from producers Blauberg and Vents ZERN heat exchangers are installed.
Heat recovery: The heart of every system
Heat recovery units are the core of ventilation systems, enabling the transfer of warmth from outgoing air to incoming fresh air. Modern units achieve up to 92% heat recovery efficiency, resulting in substantial heating cost savings.
Which system should you choose?
The choice depends on specific needs:
- Optimal for smaller spaces and quicker installation is decentralized ventilation system.
- Choose a central system for larger properties and optimal air circulation.
