Heat Recovery Ventilators

Why You Need A Heat Recovery Ventilator (HRV)

Each day your family expels between 10 and 50 litres of moisture from cooking, bathing, dish washing, and even breathing.

Combine this with Victoria’s moisture-rich climate and the trend towards “tightening” homes for improved energy efficiency, and you have an ideal situation for humidity damage, premature rot, and mold issues.

You may have seen the early signs of mold appearing as black spots or green fuzz on your window sills, inner cupboards or inside closets. These are symptoms of poor ventilation, something you need to take seriously, particularly if you suffer from allergies or other respiratory ailments.

For a healthy, safe and mold-free home, air needs to circulate and be continually exchanged with fresh outside air.

Proper ventilation is critical in reducing these risks. A simple bathroom fan with a timer or dehumidistat can go a long way to relieving moisture issues in your home by automatically turning on when moisture levels are too high.

This takes care of getting stale, moisture-laden air out of your home, but one of the drawbacks is that it creates a vacuum that pulls air through your home walls, bringing in dust, odors and other contaminants from building materials.

Breathe easier with an HRV

A Heat Recovery Ventilator (HRV) solves this problem by creating balanced ventilation.

HRVs transfer heat from outgoing stale air to incoming fresh air, resulting in better air quality, less moisture, greater energy savings, and ultimately, a healthier home environment.

HRVs are a relatively simple add-on to a heat pump/air handler installation, but they can also be retrofitted into existing forced air systems too.

Best uses for an HRV

HRVs are perfect for tight, moisture-prone houses because they replace the humid air with dry, fresh air.

But in winter, Victoria’s excessive outdoor humidity makes an Energy Recovery Ventilator (ERV) an even better option.

Benefits of an Energy Recovery Ventilator (ERV)

An ERV works similar to an HRV, but also reduces the amount of outside moisture coming into your home.

In summer, when the outside air is drier, the ERV reverses, limiting the amount of moisture expelled from your home, resulting in less shrinking and cracking of millwork, hardwood floors and wood furniture.

An added bonus is that an ERV also recuperates the energy trapped in moisture, which greatly improves the system’s overall heat recovery efficiency, saving you even more money!
