Everything you need to know about heat recovery systems

Heat recovery ventilation systems, used in passive homes and buildings, and regular houses alike, are becoming more popular in Australia. If you’re an environmentally-conscious homebuyer or builder, or you want lower energy bills and cleaner air in your house, a heat recovery system could be right for you.

What is a heat recovery system?

A heat recovery system is a home ventilation method that uses hot air from inside your house (usually from a roof space or attic) to warm fresh air from outside. It ‘recovers’ existing heat in your house – that normally escapes through windows or vents – and uses it as an energy source. As it’s drawing in fresh air from outside, it recycles the air in your home – ensuring you breathe cleaner.

Heat recovery systems are used in passive houses and low-energy homes as they’re far more energy-efficient than conventional heating and ventilation. By extracting unused hot air, for example, from your roof, and drawing in clean air, they can also do wonders for reducing moisture.

The benefits of a heat recovery system

There are a number of benefits to using a heat recovery system in your home, including:

  • Reduced heating bills and money saved
  • Improved air quality
  • Ongoing protection against moisture damage.

Let’s look at those benefits in more detail.

Save money by reducing your heating and energy bills

Having a comfortable temperate at home doesn’t have to cost the earth. With a heat recovery system, you can recapture up to 90% of ‘lost’ heat. This means your home is far more energy-efficient, as you’re using the existing warmth in your home, cutting your heating bills and saving you money.

Make sure you’re breathing clean air with a well-ventilated home

Heat recovery systems ventilate your house by drawing in filtered fresh air from outside and expelling stale air. Meaning your home circulates clean air more often and removes pollutants that accumulate from sources such as:

  • Household cleaning products (e.g., bleach)
  • Fungal growth (mould spores)
  • Gas cooking
  • Allergens (e.g., pet dander)
Protect your family and your house against moisture and mould

The effects of mould in your home can range from an unsightly inconvenience to posing a potentially serious health problem. Mould grows best in damp and poorly ventilated areas, and is the result of excess moisture. As heat recovery ventilation systems reduce humid (moist) hot air in your house, they also remove the nasties it creates, such as mould.

Vaccaro was the original electrical installer of my home. Their workmanship and materials were of excellent quality. They were extremely helpful, efficient and friendly whenever I asked for help. My special regards to Cameron for responding to my after-sales requests promptly and Robert for helping me resolve some technical issues and enhancing my understanding of the wiring system design.

Vaccaro was also the original air-conditioning installer of my home. Sonya and her teams were very polite and attentive and provided speedy responses to servicing requests. The technicians are well trained and equipped and as a result the refrigerant leak was fixed in no time. They also made good the controls and carried out air balancing.


I was a little nervous doing my electrical appointment on my own as my partner was unavailable. Janae (Electrical Design Consultant) was friendly, helpful and had a clear understanding of everything, making the electrical appointment stress-free. Janae was quick with responding to any enquiries or emails. I was very happy with her service & would highly recommend.

Happy to give a big thumbs up and thank you to Richard in the sales team and the guys who replaced our 22 year old full ducted system in our double storey home, with a new Daikin 20kw system. Only installed one day and already appreciate how quiet the unit is. Despite the rain they were through the job in a few hours and were completely professional, very happy to recommend this company.


Thank you, Richard, Jimmy, and the rest of the Vaccaro team, for providing such timely and professional service, installing a split air conditioning system in my home today. Jimmy’s level of awareness to be respectful of the peace and cleanliness of the property during the installation was greatly appreciated. My apartment feels lovely and toasty – I may never leave!
