Whole House Ventilation Systems: Different Types and Their Benefits

In recent times, interest in systems of quality air provision has become popular in Australia. More and more people are now installing quality home ventilation systems as they are now realizing the many benefits. However, it’s important to ensure that your home ventilation system is installed in accordance with the Australian Standards and Workplace Safety and Health regulations.

Some of the benefits that come from using a whole house ventilation system include:

Eradicates dampness and condensation, which alter room temperature and make your house uncomfortable to live in.

It helps in controlling mould and mildew that can damage your rugs and other fixtures placed on the floor.

Fresh air flowing through your house relieves symptoms of allergies.

Remove odours through circulation of fresh air in the house.

Improve air quality through circulation, whereby carbon dioxide is let out and oxygen is introduced into your home. 

Saves money with lower energy bills, since you don’t need heaters to warm the house.

The systems are made according to product specifications you personally give, climatic conditions where you live and particular structural designs of your house. Such systems have medical grade filters that help supply fresh air into the house; therefore, creating a healthy environment for the people living in or visiting your home. 

There are four basic house ventilation systems from which you could select one that best suits your requirements:

I. Exhaust Ventilation System

This system is most suitable for climates that are colder. It’s also simple and quite economical. A single unit will comprise of a fan that is connected to a single centrally located exhaust point within your house. A better design would be to connect your fan to ducts coming from a number of rooms which generate the most pollutants, such as kitchens and bathrooms. Take note that all exhaust systems in Australia must be installed in accordance with Australian Standard AS 1668.2 of 2002.

II. Supply Ventilation System

This system is best for climates that are hot or mixed. It utilizes a fan in pressurizing your home. This will push outside air into your house, while air leaks out through any vents within the house shell, bathroom and fan ducts. It’s also relatively inexpensive to purchase and install.

III. Balanced Ventilation System

This system is suitable for all types of climates. It typically has two fans and two duct systems. The first two will bring in fresh air as the second two take out stale air. In addition, it will exhaust air from any of your rooms where pollutants and moisture are often generated in large volumes, such as your kitchen, bathroom or laundry room.

IV. Energy Recovery Ventilation System

An energy recovery ventilation system (ERVs) presents a controlled method of ventilating your home, while minimizing loss of energy. It’s costly to install compared to the other systems. In addition, when operating in extremely cold climates, the ERV will require specific devices for it not to freeze up or even form frost. It also needs more frequent maintenance compared to the other ventilation systems.
