Heat Recovery Ventilation (MVHR) Rigid Ducting

The best practice is to use larger diameter, 125mm diameter branch lines and up to 250mm diameter main lines, which can carry the necessary high volumes of air at low velocity (depending on size of system).

Benefits of Rigid Ducting

Rigid, large diameter ducting is the preferred choice to provide a smooth flow of air with the least resistance, causing less noise (from both fans and air turbulence) and costs less to run. A minimum of 25mm aluminium foil backed wool insulation to ducting in a cold space is essential to retain high heat efficiency and avoid condensation forming in the ductwork.
