Mechanical Ventilation with Heat Recovery (MVHR) provides ventilation to the living area and bedrooms. The heat is recovered from stale air drawn from bathrooms and utility rooms, and transferred into the fresh air entering the building. These systems allow windows to be permanently sealed whilst the property has continuous fresh air, which is perfect for noisy areas of where security is particularly important.
Mechanical Ventilation with Heat Recovery (MVHR) provides ventilation to the living area and bedrooms. The heat is recovered from warmer air drawn from bathrooms, kitchens and utility rooms. The MVHR system has minimal maintenance which is an added bonus.
Mechanical Extract Ventilation (MEV) provides the continuous extraction of stale, damp air from all wet rooms such as kitchens, bathrooms and utility rooms. The system costs less to supply and install than individual separate fans required by Building Regulations and will help to reduce the amount of background ventilators required. MEV systems are suitable for a wide range of buildings, from apartments and houses to student accommodation units and nursing homes. MEV systems can be designed to ventilate either an individual apartment or several apartments simultaneously.
Hints & Tips
- Having a ventilation system i.e. Mechanical Ventilation with Heat Recovery (MVHR) system or Mechanical Extract Ventilation (MEV) system can result in a lower design air permeability rating.
*Filters require changing every year, make sure this is looked into before buying the unit.
- The MVHR and MEV systems are generally located in the loft, so access to these systems is an accessible loft hatch and ladder is required.
