A Mechanical Ventilation and Heat Recovery system is simply a way of providing ventilation throughout a house, and whilst doing so capturing the hot air leaving the house and using it to heat the colder air being fed into the house.
The process is as follows: Heat rises and as it reaches the ceiling, it will rise through an air vent placed in the ceiling. This air vent then leads, via ducting, to a heat exchanger. The heat exchanger uses this warm air to heat the cooler air which it extracts from outside as part of the ventilation process.
Because the system requires ducting and good levels of insulation, it is only viable for new builds and extreme retro-fits. However, they are very efficient and can capture up to 90% of the outgoing heat. Using a mechanical ventilation and heat recovery system also gets rid of the need for other forms of ventilation such as trickle vents in double glazing and extractor fans in bathrooms.
- Capture 90% of ventilation heat loss
- Low power consumption
