Benefits Of Whole House Ventilation Systems

Copyright (c) 2015 Matt Reardon

Whole house ventilation (WHV) through a heat recovery ventilation system is one of the best ventilation systems used in improving quality of air inside a house. Its capacity to improve a home's air circulation has made it one of the best air conditioning systems in Australia.

Technological developments in the air-conditioning industry have made this ventilation system efficient and pocket-friendly, even as it meets your ventilation needs. This is because it uses minimal electricity compared to other ventilation systems. Hence, it allows you to save on electricity spending.

Do You Need a WHV System?

If you own or occupy a house that was constructed within the past 20 years, then a WHV system is recommended. Modern houses are constructed to be airtight with an aim of increasing energy-efficiency, cost-saving and efficiency of HVAC systems.

Even with all these benefits, an air-tight house poses a health hazard to its occupants. Lack of fresh air in homes reduces comfort levels, especially when an air conditioner is operating or heating is taking place. Levels of carbon dioxide rise mostly in houses that have a large number of occupants.

Having a WHV system installed will improve air supply to all rooms of your house, while ensuring that you don't accumulate a high energy bill.

Hazards Posed by Lack of a WHV System

Apart from discomfort, you and your family face health risks that can become quite serious if proper steps aren't taken to improve your home's ventilation system. Some of the hazards include:

- Developing respiratory problems that include infections.

- Inhalation of stale, musty air.

- House structural damage, especially timber.

- Neural damage as a result of inhaling substances that are emitted by mould.

According to Mould Factsheet Australia (MFA), humidity in the air has to be kept at a stable level in every house. Failure to do so will see development of mould in your home at a bewildering rate.

Also, having little humidity indoors will cause you to suffer from itchy eyes and sore throats. With a WHV system in place, all these problems will be averted, leaving you to enjoy the peace and comfort of your home.

What is the Appropriate Ventilation Rate?

While having an air conditioner gives you the assurance of quality air in your house, not all systems qualify as appropriate ventilation systems. You are likely to experience several health complications if your house is poorly ventilated, which include dry eyes, dry mouth and breathing problems.

There are regulations put in place to govern production of air conditioners and ventilation systems. A ventilation of 0.35 rate-change in air per hour is recommended by standard 62.2 of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). The same rate is recommended by the Australian Standard AS1668.2.

Your house is a sanctuary for your family. Furthermore, your health and that of your loved ones is highly important. Therefore, you should seek only the best quality ventilation system for your home.

It's recommended by the Australian Refrigeration Council always to seek services of experienced and licensed HVAC contractors in Australia. Licensed contractors can provide you with reliable information about different ventilation systems and cost implications when installing a WHV system for your home.
