PIV Units for Flats

piv units for flats

Can you have a PIV unit in a flat?

Yes, it is possible to have a PIV (Positive Input Ventilation) unit installed in a flat in the UK, as long as the unit is suitable for the size and layout of the property and meets the relevant building regulations.

PIV units work by drawing in fresh air from outside the building and distributing it throughout the property. This helps to improve indoor air quality and reduce the risk of condensation and mould growth.

Before installing a PIV unit, it is important to consult with a qualified ventilation specialist or building professional to assess the specific requirements of the property and ensure that the unit is installed correctly and safely. It may also be necessary to obtain permission from the building’s management company or landlord before installing the unit, particularly if it involves any modifications to the property’s ventilation system.

Where can you install PIV unit in a flat?

If it is not possible to use the loft or attic space to install a Positive Input Ventilation (PIV) unit in a flat, there are other options that can be considered:

  1. Wall-mounted PIV unit: In some cases, it may be possible to install a wall-mounted PIV unit in a hallway or other central location in the property. This can be an effective alternative to an attic-based unit, although it may not be as discreet or aesthetically pleasing.
  2. Ceiling-mounted PIV unit: Another option is to install a ceiling-mounted PIV unit in a central location in the property. This can be an effective way to distribute fresh air throughout the property, although it may require some modification to the existing ceiling structure.
  3. Window-mounted PIV unit: It is also possible to install a window-mounted PIV unit in a flat. This type of unit is designed to fit into a standard window opening and can be an effective way to introduce fresh air into the property. However, it may not be as energy-efficient as other types of PIV units and may not be suitable for all types of windows.

It is important to consult with a qualified ventilation specialist or building professional to determine the most appropriate option for installing a PIV unit in a flat, based on the specific requirements and limitations of the property.
