Mechanical Ventilation And Heat Recovery Systems


The need for ventilation

Each and every one of us requires fresh air to survive, with each person exhaling between 10 and 75 litres of carbon dioxide and 175 grammes of water vapour per hour. A family of four produces between 10 and 15 litres of water vapor each day through cooking, washing and breathing. Dust mites have proven links with over 80% of asthma cases and thrive when humidities are high. What’s more within a typical home there are traces of ammonia, acetic acid, methane, nitrogen monoxide and formaldehyde from cleaning products and building materials.

Unless ventilation is added these contaminants will linger within the home and will affect both the health of the occupants and can lead to damage to the fabric of the building itself. A well designed fresh air system can reduce these levels significantly, replacing contaminants with clean fresh air.

Mechanical ventilation and heat recovery means everyone in the home can have all the fresh air they require without having to pay the energy cost for heating it up to a comfortable temperature. The Heat recovery system also reduces the carbon footprint of the home, reducing the reliance on fossil fuels needed to effectively heat up the property.

Heat Recovery Ventilation (HRV)

The heat recovery system extracts used air from the home and at the same time uses the heat from the extracted air to heat up fresh air from outside.

Each heat recovery system is supplied with a summer by-pass unit, this allows the cooler summer night-time fresh air to by-pass the heat exchanger providing an immediate cooling effect as well as pre-cooling the building fabric prior to the next warm day. The standard controller even provides an energy gain display to show you how much energy is saved in using this feature.

The benefits

  • Energy efficient – heat exchange efficiency of over 95%
  • Summer by-pass fitted as standard and includes automatic operation, display for energy saved and, plug and play fitting
  • Standard multi-function ebus remote control can be positioned up to 30m away from the main unit for maximum adaptability
