Fresh Air Home Ventilation with Lossnay Heat Recovery.

Lossnay VL-220 is the ultimate home ventilation system that provides fresh clean air (from the outside not attic space), removes both moisture and stale indoor air and effectively recovers heat not only from outgoing stale air but also from damp areas such as kitchens and bathrooms. Featuring the new advanced Diamond Heat Exchanger, heat is recovered from both outgoing stale air as well as from damp areas such as kitchens and bathrooms. This heat is utilised to pre-heat incoming fresh air so your heating system is not required to work as hard to maintain desired room temperature.

Balanced Pressure Heat Recovery Ventilation Solutions

Lossnay by Mitsubishi Electric, is an advanced Fresh Air Heat Recovery Ventilation System that captures and filters fresh outdoor air (as opposed to attic air) to replace indoor stale air for an all-round healthier, drier and warmer home. But what makes Lossnay so different from other ventilation systems is our patented Heat Exchanger, which is the secret to the heat recovery capabilities of the Lossnay ventilation unit and provides several important benefits.

The Mitsubishi Electric Lossnay Difference

What makes the Balanced Pressure Lossnay VL220 Heat Recovery Home Ventilation System from Mitsubishi Electric so different from other systems is our advanced Diamond Lossnay Core at the heart of the heat exchanger.

Features

Draws in clean fresh air from the outside not the attic

Removes stale air from the inside

Circulates fresh air without draughts

Controls moisture by managing humidity levels

Heat recovery from stale outgoing air

Efficient heat recovery from damp areas

Whisper quiet operation from 14dBA

Balanced Pressure Ventilation

Designed for modern homes that are more airtight

Pressure

Unlike ordinary positive pressure ventilation systems, the patented Diamond Core and built in drain outlet allows the system to also be effectively utilised in damp areas such as kitchens, bathrooms and toilets to help extract moisture and maximise recovery of additional heat energy from these damp areas at the same time.

The available energy is absorbed and re-used to provide pre-warming in winter or pre-cooling in summer, rather than going to waste by directly transferring this air outside. In doing so, moisture build up in your home is minimised while healthy humidity levels are maintained and managed.

Quiet

The end result: your home is ventilated with fresh, filtered and clean pre-warmed (or cooled) air at the same time whilst maintaining optimum humidity levels for healthy living. The system is super energy efficient and designed specifically to be whisper quiet.

Why outside air, not attic air?

Not all air is created equal. Lossnay only draws fresh air from the outside specifically – it does not draw air from the attic. The absence of significant air movement common in attics means the air is likely to be stale. In addition, build-up of dust, dirt and other contaminants such as mould, insect and rodent droppings makes this air much harder to filter before it is distributed through your home. This is why the Balanced Pressure Lossnay system specifically utilises direct fresh air instead.

Balanced Pressure Fresh Air Home Ventilation vs Positive Pressure Roof Air Ventilation

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

Old ‘positive’ pressure
forced roof cavity ventilation

Air goes in and gets trapped.

These systems typically force air into the home from the attic space and specifically require gaps in the building structure (common in older homes) to facilitate air displacement. As these systems are not designed to recover heat energy to help pre-warm incoming air, colder incoming air will require more additional heating – adding to your power bill.

New Lossnay ‘balanced’ pressure
fresh air heat recovery ventilation

Air goes in and comes out.

Balanced ventilation mechanically removes stale air and replaces it with clean, fresh air at the same rate. It is also fitted with a heat exchanger that actively recovers heat energy from the outgoing stale indoor air to pre-warm incoming fresh air. As such, the need for additional heating of fresh air is reduced. This system is specifically designed for modern homes that are of more airtight construction.
