Traditional ventilation systems create a significant energy burden for homeowners. When these systems draw in outside air, your heating or cooling system must work overtime to bring that air to your desired indoor temperature. In winter, cold outside air requires substantial energy to warm up, while in summer, hot humid air demands considerable cooling power.
This constant energy demand translates directly into higher power bills. Many homeowners are surprised to learn that their ventilation system can account for a substantial portion of their annual heating and cooling costs, particularly in New Zealand's diverse climate zones where temperature variations can be extreme.
Mitsubishi Electric's Lossnay systems revolutionize home ventilation through advanced heat recovery technology. Instead of simply exhausting warm indoor air and replacing it with cold outdoor air, Lossnay systems capture the thermal energy from outgoing air and use it to pre-condition incoming fresh air.
This heat exchange process occurs through specialized cores that transfer thermal energy without mixing the air streams. During winter, warm exhaust air heats the incoming cold air, while in summer, cool indoor air helps reduce the temperature of hot incoming air. This pre-conditioning dramatically reduces the workload on your heating and cooling systems.
The result is a continuous supply of fresh, filtered air that arrives at a temperature much closer to your desired indoor climate, requiring minimal additional heating or cooling to reach comfort levels.
Real-world testing across New Zealand demonstrates the substantial energy savings possible with Lossnay systems. When compared to conventional ventilation systems using electric heating and cooling, Lossnay heat recovery can deliver savings of 55% to 74% depending on your location and climate conditions.
In Auckland, homeowners can expect annual savings of approximately $583 with an LGH-35RVX3-E Energy Recovery System, while those in colder regions like Lake Tekapo can save over $2,277 annually. These savings compound over time, with five-year savings reaching $2,915 in Auckland and an impressive $11,385 in Lake Tekapo.
The savings vary by region due to different climate demands. Colder areas with longer heating seasons see the greatest benefits, as the heat recovery technology provides maximum value when there's a significant temperature difference between indoor and outdoor air.
Lossnay offers two distinct heat recovery technologies to suit different applications. Energy Recovery Ventilation (ERV) systems feature permeable Diamond Core Classic technology that recovers both sensible heat (temperature) and latent heat (moisture content). This makes ERV systems ideal for general living areas where humidity control enhances comfort.
Heat Recovery Ventilation (HRV) systems utilize non-permeable Diamond Core Plus technology that recovers sensible heat only. This design prevents moisture transfer, making HRV systems perfect for wet areas like bathrooms and laundries where you want to exhaust humidity without transferring it to incoming air.
Both technologies deliver significant energy savings, though the specific benefits vary based on your home's layout and the areas being ventilated. The choice between ERV and HRV depends on your specific ventilation needs and the areas of your home requiring fresh air.
Energy savings calculations are based on realistic operating conditions for New Zealand homes. The analysis assumes a standard 150m² home with 2.4m ceiling height, maintaining 21°C in winter and 20°C in summer, with an air change rate of 0.5 ACH (Air Changes Per Hour).
These calculations compare Lossnay systems against conventional ventilation using electric heating and cooling with a COP (Coefficient of Performance) of 1. The continuous operation scenario (24/7 for 30 days monthly) represents typical ventilation requirements for maintaining healthy indoor air quality.
Your actual savings may vary based on factors including home insulation quality, occupancy patterns, local climate variations, and current energy tariffs. However, the substantial savings demonstrated across all New Zealand regions indicate that Lossnay systems provide excellent return on investment regardless of location.
Beyond immediate energy savings, Lossnay systems offer long-term financial advantages. The reduced workload on your heating and cooling systems can extend their lifespan, reducing maintenance costs and delaying replacement needs. Additionally, improved indoor air quality can contribute to better health outcomes, potentially reducing healthcare costs.
The energy efficiency of Lossnay systems also provides protection against rising energy costs. As electricity prices increase, the percentage savings remain consistent, meaning your annual dollar savings will grow over time. This makes Lossnay systems an excellent hedge against future energy price inflation.
The energy savings delivered by Lossnay systems translate directly into reduced environmental impact. Lower energy consumption means reduced carbon emissions, contributing to New Zealand's sustainability goals. For environmentally conscious homeowners, Lossnay systems offer a practical way to reduce their carbon footprint while enjoying superior indoor air quality.
The combination of energy efficiency, improved air quality, and environmental benefits makes Lossnay heat recovery ventilation an investment in both your family's comfort and the planet's future. With proven savings across all New Zealand regions, these systems deliver measurable value from day one of operation.
