Frequently Asked Questions

What Ventilation System have I got installed, and why?
  • If your dwelling has extractors within sanitary areas, wet areas and the kitchen that operate
    intermittently, or is triggered by a light, PIR or humidity switch and has trickle vents installed in your
    external windows, it is likely you have a System 1 Intermittent Extract and Natural Ventilation. A System 1 is
    designed with an Air Tightness greater than >4.00m-3.h.m-2 at 50 Pascals to operate efficiently.
  • If your dwelling has extractors within sanitary areas, wet areas and the kitchen that operate
    continuously and has trickle vents installed in your external windows, it is likely you have a System 3
    Mechanical Extract Ventilation. A System 3 is designed with an Air Tightness <4.00m-3.h.m-2 at 50
    Pascals to operate efficiently.
  • If your dwelling has ventilator terminals in all rooms and has a central controller unit, and no trickle vents,
    it is likely you have a System 4 Mechanical Extract with Heat Recovery Ventilation. A whole dwelling
    ventilation system is designed with an Air Tightness <3.00m-3.h.m-2 at 50 Pascals to operate efficiently.
  • It should be noted the lower the dwellings Air Tightness, the less uncontrolled/ natural ventilation there
    will be and as such the less unwanted heat loss however the air change rates will reduce, hence the
    need for a Mechanical Extract and Heat Recovery Ventilation System.
How do I prepare for a Ventilation Test?

Check what fans you are buying and for what use. For instants extractors within cooking spaces require.
