Heat Recovery Ventilation

Heat Recovery Ventilation UnitModern energy efficient houses have a high air tightness, this reduces heat loss by preventing hot air leaking out or cold air flooding in,  however the house needs a supply of fresh air.  Mechanical Heat Recovery Ventilation (MHRV or HRV) provide a controlled and variable rate of ventilation as well as recovering heat from the stale  exhaust air which would normally be lost. As up 20% or more of heat loss in a house can come from air changes it makes sense to try to recover as much of this heat as possible.

Advantages of  HRV are:Heat Recovery Ventilation Duct.

  • Suitable for 75 mm stud walls.
  • Smooth inner duct lining.
  • Anti bactieral and anti stattic.
  • Easy clean of all ducting.
  • No cross talk to or from other rooms.

John qualified in the trade as a refrigeration and air conditioning technician and having worked on large heating and ventilation plants in buildings such as the Ilac Centre, the Irish Life buildings and the Irish Financial Centre you can be confident your HRV system will be installed correctly.
