When the dryness of summer slowly disappears and the damp of autumn and winter rears its ugly head, this is quickly followed by the nuisance of crying windows. Condensation is the visual reminder that your home is literally full of moisture, which is not only harmful to a healthy environment for you and your family, but is also a damaging and costly threat to your property.
Proper ventilation will prevent the buildup of dangerous moulds, which is great news for asthmatics and allergy sufferers. The consequent removal of moisture around the home saves thousands of dollars in home maintenance, ranging from replacing rotten window framing to replacing curtains and repainting just to name a few. With a wide range of heat recovery and passive ventilation options, Warm and Dry Homes has it covered when it comes to keeping your home healthy and dry, right throughout the year.
Our systems, mounted in the roof space, take air heated by the sun and provide free heat and fresh air into your home. We also incorporate electric heaters that kick in when things get really cold, to ensure your house is not only dry, but warm during the coldest months.

Warm and Dry Homes is proud to introduce the new HEX390 Domestic Ventilation System with Heat Exchanger – made in New Zealand for New Zealand Conditions.
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.
Under clause G4 of the New Zealand Building Code, one HEX390 unit could ventilate a standard 2.4m ceiling height house up to 450sqm. However, we recommend one HEX390 per 250sqm for optimum operation.
