Silavent Mechanical Ventilation with Heat Recovery

Helps create a healthy and clean indoor air environment whilst reducing household energy consumption.

Inadequate ventilation coupled with airborne pollutants can all lead to poor indoor air quality and as a consequence may have a detrimental effect on an occupant’s health and comfort.

Incorporating a highly efficient Mechanical Ventilation with Heat Recovery (MVHR) system is an effective way of avoiding this and helps to maintain a healthy living indoor environment.

Silavent Green Line HRX

  • Suitable for a floor area up to 180m²

Silavent Green Line HRX2

  • Suitable for a floor area between 180m² to 275m²

Note: If the floor area if greater than 275m², multiples of Silavent HRX and HRX2 units can be sited.


How MVHR Works

Also referred to as System 4 in Approved Document F of the Building Regulations, MVHR efficiently combines supply and extract ventilation into one centralised system.

As its primary function, waste, polluted and moist air is extracted from a dwelling’s wet rooms via a duct system and is passed through a heat exchanger before being exhausted outside. Fresh incoming air is filtered and as an added benefit, pre-warmed via the heat exchanger. It is then evenly distributed to the habitable rooms, thus reducing household energy consumption and the demand on existing heating systems.


The technology is most effective when installed in an air-tight dwelling as the effect is not compromised by external leakage.
