Home Air Ventilation

Home Air Ventilation

It’s not every day we think we’re on the cusp of a new phase in domestic design building, but there’s every indication that this is going to change the quality of many a future Australian home…

So what are we getting excited about? HRV, Heat Recovery (or heat exchange) Ventilation systems are now a standard feature in European homes, and it might not be long before Australian home standards follow suite. We caught up with our friends at Atlantic Australasia, who are committed to smarter climate living, to find out more about this impressive home innovation.

Why are heat recovery systems now mandatory in many European countries?

Contemporary standards mean that new European homes, particularly in the cooler regions must be air-tight and in fact, this is also true of new Australian homes. However, air-tight homes deliver their own set of subsequent challenges. An air-tight home effectively means that air cannot naturally circulate, nor can any fresh air enter the space. This can lead to a build-up of moisture, a build-up of Carbon dioxide levels, increased mould problems, and basically compromise a home’s overall comfort. So to overcome this, new European homes must install air ventilation systems with heat exchange - or heat recovery - properties.

HRV Systems

Is this technology available for Australian homes?

It is, yes. We sell the French Duo-lix Max, a product that extracts moisture and odour from all wet areas in the home (so bathrooms, toilets, laundries, kitchens). The Duo-lix Max strips heat energy out of the air and redistributes it evenly throughout the home. This process is 92% efficient, and in short delivers fresh, warm and filtered air throughout all spaces in the home. No heat is lost in the process, so homes are not burning up excess fuel yet they can maintain a consistent temperature throughout the entire dwelling.

What happens in summer?

The Duo-lix Max features a summer cooling system. This is not engaged whilst the outside air temperature is higher than the inside air temperature. So in the heat of the day, no hot air is pulled in. This is called a ‘summer by-pass’. Instead, the system relies on an internal circulation to regulate inside temperatures. The moment the outside temp drops lower than the inside temp however, the system engages and immediately starts pulling in this cooler air.

What results can people expect?

We’re getting terrific feedback from our customers. Aside from the feeling of fresh air throughout the home, they’re also noticing other benefits such as towels drying faster in winter, little to no mould in the bathroom, and regulated, consistent temperatures throughout their homes. We’ve also had a lot of feedback around minimised dust levels in the home – these systems feature S7 filters.

Is this system compatible with my home heating and cooling system?

Yes, it works side by side with these systems providing more balanced heating and cooling.

What if you’re going away? Do you just turn off the Duo-lix Max?

No – it has a holiday mode. This enables the unit to keep fresh air circulating quietly whilst you’re away, so you return to a lovely home versus one that smells like it hasn’t seen the light of day for some time!

How much does it cost to run the Duo-lix Max?

The average household will spend only $150 a year to run this system – it only needs about 100-watts of electricity.

What about installing the Duo-lix Max? How much does that cost?

The Duo-lix max is very cost efficient. Customers are welcome to email their plans and we will provide an obligation free design and quotation. The Duo-lix Max can only be installed in new homes before they are built. The quotation includes the system, the design, the installation, all componentry as well as commissioning to ensure all air pressure is the same at every inlet and outlet in the home.

What about people who would like this system in an existing building? What can they do?

Due to the incredible success of the Duo-lix Max, we’re about to launch the Duo-lix, which can be retro-fitted into existing homes provided there is adequate ducting and access. It is designed to fit through a man hole. This system is up to 90% efficient.

Can anyone install these systems?

Atlantic Australasia recommends specific installers – we’re happy to share these recommendations with any of our customers.

Is there anything new on the radar for the Duo-lix Max?

Actually, yes. There will soon be a new system featuring CO2 sensors, so if for example a log fire is burning and too much oxygen is being absorbed, the system registers this and automatically releases more fresh air. We need no further convincing! Give the team at Atlantic Australasia a call to find out more about home ventilation with heat exchange in your home.
