Breathe easy
Mechanical ventilation with heat recovery (MVHR) draws stale air out of each room at an extraction point. The air is passed through ducting to a heat exchanger and expelled outside. The extracted warmth is transferred via the exchanger to fresh air flowing through a separate run of ducting into the rooms. Filters in the main unit remove particles so that the circulating air is free from pollutants. Usually installed in a loft, basement or plant room, the air-handling unit is the hub of the system. It is connected to a series of ducts that are attached to extraction and supply points.
