Why Unovent?

Normal family life creates moisture and pollutants throughout your home

Have you ever thought about the air you breathe in your own home?

Have you ever walked into a home where the air is stale and feels stuffy?

Good ventilation circulates air around your home, removing odours, reducing moisture and flushing out pollutants and irritants.  

Unovent® is an affordable positive pressure ventilation system taking fresh, filtered air from the roof space (v-line™) where it is constantly being changed because this area is well ventilated.  The system brings down this air down from the roof space through one or more room outlets - each with its own fan and a washable filter - into the selected rooms.  This in turn gently pushes the stale and moist air out through gaps under doors or around windows and through bathroom and kitchen vent systems. 

The result is improved air quality – filtered to be fresh - creating dry and warm air without the nasties for a healthy home designed and affordable for New Zealand families.

Is your home under constant attack from mould, mildew or worse – hidden rot?

In all homes, inadequate ventilation means poor air quality, window condensation and moisture build up in drapes, carpet, furniture, walls and ceilings.  This creates an unhealthy damp, often musty smelling environment, which encourages rot, mould, mildew and dust mites – potential causes of asthma and allergies. 

With the Unovent® positive pressure ventilation system, air is constantly being changed by the system which brings down this fresh, unpolluted air from the roof space through washable G4 filters into the selected rooms of the home.  Stale and moist air is pushed out and the result is less moisture for mould and rot to thrive in.

A Dry Home

Is your home soaking up moisture like a sponge?

Typically the presence of people and daily activities such as washing, drying clothes indoors, cooking, cleaning, smoking and showering can create poor indoor air quality that is damaging the health of you, your family and your home.   Daily living can add between 10 to 20 litres of moisture each day for a family of 4.   Condensation on windows are a sign of a damp home which is struggling to breathe.    

The Unovent® positive pressure ventilation system takes fresh, unpolluted air from the roof space through one or more room outlets - each with its own fan and a washable filter - into the selected rooms.  This in turn gently pushes the old stale and moist air out through gaps under doors or around windows and through bathroom and kitchen vent systems.  Throughout this process soft furniture, drapes, bedding, wallpaper, clothing and carpets are also slowly dried.

Is your home expensive to heat?

It’s a fact that a damp home is difficult and more expensive to keep warm.  The Unovent® ventilation system does not create drafts - gentle airflow movement continuously dilutes and displaces the old air and reduces the moisture in the rooms, carrying the poor quality air outside.

The resulting drier air is healthier and easier to heat in winter.

Wondering how much it will cost to run an Unovent system?

When we say running an Unovent system is affordable, we mean it. You're looking at less than $1 a month for a typical 4-bedroom home. Don't forget that a drier home is much easier to heat, so you'll save money on those dreaded power bills in winter too - especially if you're using an energy-efficient heat pump.

To prove our statement, here's the maths behind it.

  1. Each Unovent fan, when running at 12 volts, uses 1.08 watts
  2. Four Unovent fans use 4 x 1.08 = 4.32 watts
  3. The Unobrain uses about 1.00 watt
  4. Total watts for a 4 x Unovent system is 5.32 watts
  5. 1 unit of electricity supplied costs about 20 cents plus GST (23 cents) – a unit is 1.0 kilowatt-hour or 1,000 watt-hour
  6. Divide 1,000 watt-hour by 5.32 and we get 188 hours which is just under 8 days if running 24 hours a day
  7. Divide 30 days by 8 and we get 3.75 units used in a month (if running 24 hours per day)
  8. 3.75 times 23 cents equals 86.25 cents per month (if running 24 hours per day which typically does not happen on average)

The Unovent “distributed fan system” uses far less energy than traditional ducted systems. These systems typically have a single centralised fan which need to be sized to overcome the restrictive flow effect of all of the ducting to supply air to the room outlets. Because these ducted outlets are typically located just inside the door, for example with bedrooms, ducted systems also require a greater flow of air to ensure all air in the room is eventually exhausted from the room.  A ducted system usually costs anywhere from $4 to $30 per month to run.
