Heat Recovery Systems Explained
MVHR (Mechanical Ventilation Heat Recovery) systems, sometimes referred to as whole house ventilation systems, are getting a higher profile in domestic properties as their value in improving energy efficiency, removing stale moist air and in some cases filtering pollen and other airborne dust is recognised. This article explains what they do, what the components of a Mechanical Ventilation Heat Recovery System are and the reasons for their growing popularity in new and existing homes.
What does an MVHR system do?
An MVHR system removes moist stale air and delivers fresh air to a property, in an energy efficient way.
It works by extracting warm, moist air from around the home, putting it through a heat exchanger to extract the heat and then expelling the air to the outside. At the same time it takes fresh generally colder air from the outside and uses the heat from the heat exchanger to warm the incoming fresh air before delivering it around the house. Typically stale air would be removed from kitchens, bathrooms and toilets and fresh air would be introduced into living and sleeping areas such as lounges and bedrooms.
The system allows you to control the speed with which air is changed in a house, without relying on extractor fans or opening and closing windows. The system can be managed using a control panel possibly linked to humidity or carbon dioxide sensors or boost switches. The system can increase the speed of air changes if a bathroom reaches a specific level of humidity because someone is showering. The system can be given a manual boost to clear cooking smells more quickly.
