Heat Recovery Ventilation systems are also referred to as HRV systems or Energy Recovery Systems and they aim to ventilate your home without undue loss of heat in winter or heat gain in summer.
They are also the best system for airtight homes. Most ventilation systems in New Zealand are positive pressure systems where the fresh air displaces the stale moisture laden air through gaps around windows, doors, light fittings etc.
There are three main reasons why Balanced or Heat Recovery Ventilation (HRV) systems are of increasing relevance for New Zealand homes:

A Heat Recovery System balances the amount of air brought into you home with the amount taken out. In addition, a heat exchange system transfers most of the heat energy of the outgoing air to the incoming air so that it is both fresh and warm.
In contrast most traditional systems in New Zealand are positive pressure systems that push fresh (often cold) air into the home and in doing so push the air you’ve already heated outside through gaps around windows, doors etc.
It varies by individual system but up to 86% of the heat energy can be recovered and transferred to the incoming ventilated air.
Both. Certainly new homes should focus on a Heat Recovery Ventilation system since modern homes are more airtight and don’t have the small gaps around windows and doors typical of older houses that positive pressure systems rely on.
Heat Recovery Systems are also suitable for old homes. Typically older homes are less well insulated and so every effort to minimise heat loss should be taken. A positive pressure system pushes the damp but heated air outside as it brings in fresh dry air.
