Combine a Central Ducted Heat Pump System with Fresh Air Heat Recovery Ventilation

In addition to its exceptional heating and cooling capabilities, Mitsubishi Electric offers a cutting-edge solution for ventilation through the Lossnay Core. This unique system works by efficiently recovering heat from stale air extracted from your home and pre-warming or pre-cooling the incoming fresh outdoor air.

Mitsubishi Electric Lossnay Ventilation system can be integrated with a ducted heat pump system offering a complete home heating, ventilation and air conditioning solution.

The Mitsubishi Electric Lossnay System is a patented heat recovery ventilation solution that uses fresh air (not attic air) to ventilate your home. The system works by extracting stale air from inside your house and replacing it with allergen-reduced fresh air from outside. At the same time, the system recovers heat energy from the stale air and uses this to pre-warm (or pre-cool) the incoming air. The result? A warmer, drier and healthier home that costs less to heat (or cool).

Optional Wi-Fi and Zone Control
Creating a healthy living environment is important when renovating or building a new home. In addition to efficient heating, ventilation and air conditioning, this should include the optimum amount of fresh air.

Current building regulations now demand homes to be built more airtight as they are subjected to higher insulation standards, but this often means a lack of natural ventilation and can lead to a build-up of moisture-laden stale air within the home. Mould and dampness can compromise both building materials as well as furnishings inside the home, especially window sills, curtains and carpets, let alone also having a harmful impact on the health of the home’s occupants. The option of leaving doors or windows open to allow more fresh air to enter is often not the solution from an outdoor noise, weather or security perspective and can make heating the home less energy efficient.

This is where the Mitsubishi Electric Lossnay System can make a real difference.

The Lossnay Difference

The Mitsubishi Electric Lossnay Fresh Air Heat Recovery Ventilation System allows you to have a well-ventilated home without the need to open windows. The Lossnay Ventilation system works by extracting stale air from inside your house and replacing it with allergen-reduced fresh air from outside.

Furthermore, Lossnay also recovers heat energy from the outgoing stale air to pre-warm (or pre-cool) the fresh air being drawn into your home.
Why Choose Lossnay Fresh Air Heat Recovery Ventilation?
Draws in fresh air from the outside not the attic
Removes stale air
Reduces moisture build-up
Improves air quality for better health and wellbeing
Efficient energy recovery that pre-warms or pre-cools incoming air Ventilation Solutions to Suit Most New Zealand Homes
Mitsubishi Electric offers a full Lossnay Fresh Air Heat Recovery Ventilation Range from in-ceiling whole home heat recovery solutions, to ducted heat pumps and wall-mounted single room models. The latest addition to their ducted heat pumps' range is the Vertical Lossnay that features a small, upright footprint allowing it to be placed in the garage or a utility cupboard and therefore isn’t limited to an in-roof installation.

Lossnay effectively helps to reduce moisture from your home by constantly bringing in fresh filtered air from the outside (not attic air) and directly removing damp stale, stagnant air that causes condensation. Furthermore Lossnay not only effectively manages humidity levels for better health and well-being, it also recovers heat energy from the stale outgoing air at the same time. This is then used to pre-warm (or cool) the incoming fresh air, maximising energy efficiencies.

Lossnay Heat Recovery Ventilation from Mitsubishi Electric is revolutionising indoor air quality. While most home ventilation systems are no better than opening a window letting valuable heat escape, Lossnay brings fresh filtered air in and recovers heat energy from the outgoing stale air which is then used to pre-warm the incoming fresh air. The end result is a healthier, drier and warmer home whilst maximising energy efficiencies.
Here's how it works:
Exhaust Air (EA): As the stale RA is removed, the Lossnay Core recovers useful heat energy from it. The air is then exhausted (EA) outside along with unwanted pollutants.
Return Air (RA): The stale air extracted from your home, which may contain high levels of CO2, odours, and pollutants, is considered Return Air (RA). Unlike positive pressure house ventilation systems, Lossnay can recover heat energy from RA.
Outdoor Air (OA): Fresh outdoor air (OA) is introduced and filtered before passing through the Lossnay Core. This allows the OA to be pre-warmed in winter or pre-cooled in summer using the energy recovered from the RA.
Supply Air (SA): The pre-warmed or pre-cooled supply air (SA) enters your home, providing fresh, comfortable air for your indoor environment.

The Benefits of the Lossnay System
