Install a HEX390 balanced pressure heat recovery system in your home or rental property today and never look back.
Your home is one of the largest investments you will make and how you protect that investment from moisture and mould should be front of mind.
A majority of all kiwi homes have a serious mould and damp issue, 46% of homes are prone to condensation. Adding to that, many New Zealanders suffer from hay fever, dust mite allergies, pollen allergies, or asthma, which can be triggered by the unhealthy, allergen filled air within our homes.
Traditional domestic ventilation systems are ‘positive pressure’. They bring air in from outside via the roof space and force the stale air out through gaps around windows and doors. The incoming air from these systems has to be heated or cooled to keep the house warm in winter or cool in summer.
The HEX390 is a ‘balanced pressure’ system. It extracts air from the house and at the same time brings fresh air in. These two streams of air pass through a heat exchanger, which warms incoming air in winter and cools incoming air in summer. This means that up to 80% of the energy which would be wasted using a traditional positive pressure system is recovered by the HEX390, resulting in significant energy savings and therefore cost savings.
Until recently, balanced pressure ventilation systems have been considerably more expensive than traditional positive pressure systems. However, a HEX390 balanced pressure system can be installed for a similar price as a traditional positive pressure system.
It makes sense that the air we bring into our homes should be filtered, fresh and drier for the family and the HEX390 home ventilation system will do just that by improving the indoor air quality.

Under clause G4 of the New Zealand Building Code, one HEX390 unit could ventilate a standard 2.4m ceiling height house of up to 450sqm. However, we recommend one HEX390 per 250sqm for optimum operation.
