In modern, energy-efficient buildings, air quality is crucial for health and living comfort. Due to the high airtightness of these structures, natural ventilation is often insufficient, leading to moisture buildup, mold growth, and poor air quality. This is where local ventilation systems with heat recovery come in, ensuring fresh air without significant heat loss.
What is a decentralized heat recovery unit?
A decentralized heat recovery unit is a compact device designed to ventilate individual rooms. It operates on the principle of air exchange, where the outgoing stale air transfers its heat to the incoming fresh air. This helps retain warmth inside the room, reducing heating costs. Additionally, these systems filter out dust, allergens, and other pollutants, improving indoor air quality.
Advantages of decentralized ventilation systems with heat recovery
- Easy installation – Unlike central systems, they do not require extensive construction work, as they are installed directly into an exterior wall.
- Energy efficiency – By recovering heat, they reduce the need for additional heating, resulting in lower energy costs.
- Improved air quality – The filters in the heat recovery unit remove dust particles, allergens, and other harmful substances from the air.
- Prevention of moisture and mold – Continuous ventilation reduces the risk of moisture accumulation and mold formation in the room.
Cost of decentralized heat recovery units in 2025
The cost of local heat recovery units varies depending on capacity, manufacturer, and additional features. According to previous data, prices are on average around €750, depending on the selected model and installation complexity. Considering market trends the price will remain the same in 2025. For precise pricing, it is advisable to check current offers.
Investing in a decentralized ventilation system with heat recovery is a step toward better living quality and energy efficiency. With fresh and clean air, reduced heating costs, and easy installation, these systems are an excellent solution for anyone looking to improve comfort in their home.
