Home ventilation systems can help you save on heating and cooling costs throughout the year and will provide you and your family with clean purified air, helping those with common illnesses like asthma and/or respiratory issues by removing moisture and eliminating harmful fungus.
Whether you’re a homeowner, landlord, building new or renovating, maintaining good air quality/ventilation creates a healthy environment.
There are two types of residential ventilation systems to consider:
Positive Smart Vent
These systems (which are most commonly used in New Zealand) draw fresher, drier air into the home from either the roof cavity or outside. This air is then passed through a high efficiency filter and introduced into the home. This introduced air forces out the moist, stale air that causes condensation, mould, and mildew.
Balanced pressure heat/energy exchanger ventilation systems
These systems use the energy the household has paid for, say to heat from the lounge, and pass it through an advanced heat or energy recovery converter. It then tempers the fresh, dry air from outside before moving it to rooms that need it most. Balances pressure systems (also known as heat recovery systems) are especially suited to modern airtight homes or those homes in the colder parts of New Zealand, assuming the property already has adequate heating, insulation and is built to modern building standards. Since this systems works via an air-to-air heat exchanger that transfers heat from the inside air to the air coming in from outside, it is most effective for airtight homes, as more of the heat can be recovered and utilised.
