What is a heat recovery system?
Put simply, such systems are known as MVHR, which stands for Mechanical Ventilation with Heat Recovery. It’s a ventilation system that works to remove stale air from your home and introduce fresh air. However, that’s not all it does – it also uses the heat from the air escaping your home to warm the new air as it enters in a heat exchange.
It’s not part of your heating system, but the work it does in warming cold air and introducing it to your home means that you can make significant savings on your energy costs.
The benefits of MVHR
A heat recovery system works best in a house that is thermally efficient, which modern builds tend to be. In such circumstances, and with the latest systems in place, it’s possible to save around 90% of the warm air escaping your home. Considering this usually leaks out of the roof and windows and disappears, it makes a considerable difference.
That’s not all it does, however. The new air is also carbon filtered by the ventilation as it enters, meaning that many allergens such as pollen are removed. This is great news for those who suffer from asthma, hay fever, rhinitis and other allergic conditions, while the system also replaces carbon dioxide with fresh oxygen.
