Why choose Lossnay - Fresh Air Energy Recovery?

Draws in fresh outdoor air

Circulates the air continuously

Retains heat

Assists moisture control

Helps keep heating bills down

World leader in ventilation systems, Mitsubishi Electric’s patented Fresh Air Energy Recovery System is available in New Zealand. Because Lossnay uses fresh air (not attic air) to ventilate your home, you get the best of both worlds - fresh air into the home whilst reducing dampness - and without the excessive added heating costs that most alternative systems cannot prevent.

Lossnay ensures the air in your home stays fresher, cleaner and drier. By recovering indoor heat you will also increase energy efficiency.

Why is ventilation important?

Ventilation is important to maintain air quality and remove moisture in your home creating a healthy environment. Home design and improvements have meant that homes are becoming more air tight and easier to heat, this in turn has increased the need for adequate ventilation.

Old vs. new ventilation systems

There are two types of Ventilation systems available in New Zealand:

  1. Old ‘positive’ pressure roof cavity ventilation systems
  2. New Lossnay ‘balanced’ pressure fresh air heat recovery ventilation systems

Energy and cost savings

The Lossnay Fresh Air Ventilation system works by extracting stale air from inside your house to remove damp, odours, dust, bacteria and gasses. This air is then replaced with allergen reduced fresh air from outside (unlike some systems that recycle it from the dust-filled attic). Where Lossnay gets really clever is with its environmentally friendly 'Energy Recovery' system. Put simply, energy within the stale air can be recovered and used to pre-heat or pre-cool the fresh air being vented in. So it warms the fresh air in winter, and cools it in summer.

Energy recovered in Winter

If outdoor air is 7˚C and the indoor air is at 20˚C, then the supply air from the Lossnay would be 14.5˚C. The supply air only needs to be heated by 5.5˚C, to reach 20˚C comfort temperature not 13˚C, thus saving energy and money. With conventional ventilation systems, this energy would normally be wasted!

Energy recovered in Summer

If the outdoor air is 24˚C and the indoor air is 20˚C, then the supply air would be 21.7˚C. In summer the house will feel clean and fresh, even if you leave the house locked up for a long period of time.

† Note: Ventilation systems do not create heat. During winter Mitsubishi Electric recommends that Lossnay Fresh Air Energy Recovery Ventilation is used in conjunction with a Mitsubishi Electric Heat Pump. This will ensure a complete home solution providing both fresh air and energy efficient heating. * Supply temperatures may fluctuate with humidity.

Preset your Comfort

Lossnay’s intelligent preset comfort zone ensures that air warmer than 28°C in summer, or cooler than 8°C in winter will not be introduced. (Settings can be adjusted by installer).

For a healthier home

Operational reports have shown that Lossnay’s filtering reduces the level of dust in your home - so there’s less need for dusting and general cleaning, which can only be a good thing! What’s more, lingering food smells are much more manageable, while constant fresh air circulation helps to minimise the buildup of moisture.
