LOSSNAY ERV SYSREMS

Temperature Solutions designs, installs and services Lossnay Energy Recovery Ventilation (ERV) systems throughout the greater Wellington region.

> What is an ERV System?

Energy Recovery Ventilation (ERV) systems are designed to maintain indoor air quality.  This is achieved through removing stale inside air and replacing it with clean, fresh, outdoor air.  As part of the system, heat/energy is transferred from the stale indoor air to the incoming outdoor air.  In winter, prior to internal circulation, the outdoor air is warmed from the heat/energy recovered from the extracted indoor air. 

An Energy Recovery Ventilation system works in a similar way as a Heat Recovery Ventilation system (HRV) with just a few differences (detailed below).

> The Benefits of a Lossnay ERV System

  • The Lossnay ERV system creates a healthy home or office with improved indoor air quality.
  • The Lossnay system provides continuous heat recovery, even in the cool winter months.  In winter, because the system recovers heat/energy from the extracted air, less heat is required to maintain a comfortable indoor environment.
  • It maintains a constant and controlled air flow in and out of the home/office, year-round. 
  • The Lossnay ventilation system can effectively supply the required flow of outdoor air to indoor air, as specified in the NZ Building Code, Clause G4, Ventilation, Mechanical Ventilation.
  • It saves money on heating/cooling costs while offering 24-hour 7 days/week ventilation.
  • The Lossnay fresh air ventilation system delivers fresh and warmed outdoor air into your home or office.  It is a fresh air home ventilation system.
  • It has proven health benefits.  HRV/ERV systems have proven to be very beneficial to people suffering from asthma and other respiratory conditions.  The Lossnay Energy Recovery Ventilation system extracts stale air from inside the home, to outside, and with this removes and/or reduces the concentration of odours, dust, bacteria, dust mite allergens and gases.

> How the Lossnay ERV System Works

  • The Lossnay Energy Recovery Ventilation system comprises two fans and a heat exchanger.  One fan brings in fresh air from outdoors, which is then circulated throughout the home or office.  The second fan extracts and removes the stale, warm indoor air. 
  • In winter, as the stale air is extracted, available heat/energy is removed by the heat exchanger and the recovered energy is then transferred to ‘warm’ the fresh incoming air.  In the hot summer months, the heat exchanger can work in reverse. 
  • The Lossnay ERV system operates primarily as a ventilation only system.  Furthermore, it operates as a 'balanced' ventilation system, where the same amount of air goes in and out. 

> Comparison of the Lossnay ERV to a HRV System

  • Moisture Control.  The main point of difference between a HRV and an ERV system relates to moisture control and moisture removal.  Due to differences of the heat exchanger unit, HRV systems more effectively assist with moisture control and moisture removal within the home or office.  Specifically, HRV systems recover heat only from the extracted air (with no moisture being extracted and transferred between the two air streams).  In comparison, ERV systems recover and transfer heat and moisture from the extracted air to the incoming air stream. 
  • Condensate Drain.  Notably, a HRV system must be fitted with a condensate drain to remove extracted moisture.

> Comparison of the Lossnay ERV to Ventilation Only Systems

  • Lossnay – delivering fresh outdoor air:  The Lossnay ERV system removes the stale, warmed air from the rooms and replaces this air with clean fresh outdoor air.  Roof space ventilation systems are primarily designed to move air from the roof space into the living spaces below.
  • Lossnay – for energy savings.  With the more energy wasteful ‘ventilation only’ systems, these systems transfer the air from ceiling/attic spaces and circulate this air into the rooms below.  Under most winter conditions the air being introduced from the ceiling/attic space often requires reheating, thereby adding significant energy costs to the heating bill.
  • Lossnay - for balanced ventilation:  The Lossnay ERV system operates as a 'balanced' ventilation system, rather than other 'roof space ventilators'. These alternative ventilation systems should probably and more correctly be called ‘positive pressure ventilation systems’. 

> Design Information Required

Each Lossnay ERV system is individually designed and takes into consideration a number of factors including the respective floor space and house layout.  

For Temperature Solutions to design your specific Lossnay ERV system, the following information is required:

  • Plans/elevations of the proposed building/home.
  • The construction programme – if applicable.
  • Method of heating the home.
