Poistolämmitys
Poistolämmitys, also known as exhaust air heat recovery or extract air heating, is a ventilation system that recovers heat from exhaust air to preheat incoming fresh air. This system is commonly integrated into mechanical ventilation units. The primary function of poistolämmitys is to improve the energy efficiency of a building by reducing the energy required to heat fresh air introduced into the building.
The process involves drawing warm, stale air from a building, typically from areas like bathrooms, kitchens,
Poistolämmitys systems can significantly reduce heating costs, especially in colder climates. They also contribute to improved
