Heat recovery ventilation
units - how it works

A heat recovery ventilation unit provides a clean, fresh environment in your home. It delivers fresh filtered air from outside the building to the living and bedrooms and extracts stale air from high moisture areas such as bathrooms, kitchens and laundries. At the same time it recovers up to 95% of the heat from the exhaust air and transfers it to the incoming air. With a heat recovery ventilation unit you can maintain a high air quality without excessive additional energy costs.

Integrated humidity sensors constantly monitor the relative humidity in the rooms and the air volume supplied to the house is automatically adjusted until an adequate air quality is obtained.  A Dantherm heat recovery ventilation unit will provide continual clean air with a minimal heat loss. 

The benefit is increased comfort and big energy savings!

The heat exchange takes place in the counterflow heat exchanger. It consists of two separate, isolated air flows. One air flow is connected to the outdoor air and the other is connected to the extract air - in a way that the air flows are never mixed. Up to 95% of the heat from the extract air will be recovered and transferred to the incoming outdoor air, thus reducing energy bills, and making it a worthwhile investment.veksler_function
