Heating, Ventilation and Air Conditioning for Comfort All Year Round

Your home will be comfortable all year round with a home ventilation system installation from DC Installation Services.
By using the Lossnay ventilation system in conjunction with your heat pump, you'll stay cool during Christchurch's hot summers, offering a refreshing escape from the heat, especially at night. Similarly, during cold winters, this combination ensures a reliable heating system to keep your home cosy.

A home ventilation system, like the Lossnay Fresh Air Energy Recovery System, is ideal for the Canterbury climate. It not only swaps stale air for fresh air but also saves on heating by recovering heat from the air inside your home and transferring it to fresh, dry air from outside. In conjunction with a heat pump, this system provides energy recovery savings in winter by warming the cold fresh air and maintains excellent energy efficiency in summer. With an efficiency of approximately 82%, Lossnay heat exchangers eliminate the need for additional electric elements, giving you reliable temperature control year-round.

Benefits of Using Home Ventilation Systems in Christchurch

There are many benefits to using a home ventilation system over other sources such as open windows or conventional fans. Here are three that will appeal to many homeowners:

Draws in Fresh Air: Running a house ventilation system ensures that fresh air is drawn in from the outside, not the attic, maintaining a pleasant indoor environment.

Removes Stale Air: The system effectively removes stale air, preventing stuffiness and keeping your home feeling fresh.

Reduces Moisture Build-Up: By reducing moisture build-up, the ventilation system helps to prevent mould and mildew, promoting a healthier living space.

Improves Air Quality: Utilising a good filtration mechanism improves air quality, which can enhance health and well-being by reducing allergens and pollutants.

Efficient Energy Recovery: The system efficiently recovers energy, pre-warming or cooling incoming air, ensuring comfort while saving on energy costs. Lossnay also recovers heat energy from the stale outgoing air to maximise energy efficiencies.

DC Installation Services recommends homeowners install a Mitsubishi Electric Lossnay Fresh Air Heat Recovery Ventilation system. As an established heating, ventilation, and air conditioning specialist, we endorse Mitsubishi Electric systems for their reliability and energy efficiency. Mitsubishi Electric house ventilation systems are quiet, energy-efficient, and cost-effective, offer a range of units to suit various budgets and home setups, making it the best home ventilation system for Christchurch homeowners.

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 system works by pushing stale air from inside your house and replacing it with allergen-reduced fresh air from outside. It also recovers heat energy from the outgoing stale air to pre-warm (or pre-cool) the fresh air being drawn into your home.

The Vertical Lossnay Range, designed specifically for the New Zealand housing market, makes energy-efficient, super-quiet ventilation accessible to even more homes. Its slimline, vertical upright design allows for flexible installation options, not limited to in-roof spaces. With a small upright footprint, it can be conveniently placed in a garage or a kitchen cupboard. This makes whole home ventilation easier to maintain, such as changing filters, and can be seamlessly integrated into the overall building design.
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
A Lossnay ventilation system effectively helps to reduce moisture from your home by constantly bringing in fresh filtered air from the outside (not attic air) and pushing out damp, stale, stagnant air that causes condensation. 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.

Using Lossnay Heat Recovery Ventilation in conjunction with a heat pump, 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 Return Air (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.
