Heat recovery ventilation is a term generally used in the UK and Ireland, due to the climate it is rare that cool recovery is required. Heat recovery is commonly known as Energy Recovery Ventilation throughout the industry and in Europe, due to the hotter climates. Heat recovery ventilation is designed to ventilate rooms while keeping warmth in.
Air quality is important, Drafts and that little air that comes into the home or business is a good thing because it brings fresh air to breathe. Likewise, traditional extract only ventilation (where by a fan removes stale air from the room and it is made up from window vents, drafts & doors being opened) however, this is a huge waste of energy that is not only bad for the environment but that most people can’t afford, which is why heat recovery ventilation (HRV) works well.
How It Works
HRV units are generally individual through the wall units & work similarly to balanced ventilation systems. It uses the heat in the outgoing air to warm up new air that comes in via a heat exchanger, these can be found in various configurations, but in most cases, it uses two fans, one which removes the old air and another to bring in fresher air across the heat exchange unit.
Generally these units are controllable via sensors, timers or other methods, allowing you to control the outgoing and incoming air streams more efficiently.
Why It’s Popular
Anglo Nordic have many models available, some of which can recover up to 90 percent of the heat that leaves the building. Whilst they may be a slightly higher cost than traditional ventilation, over time, they will be easier on the budget & kinder to the environment.
