When it comes to home ventilation our goal here at GreenStar Energy Solutions is to design and install the best home ventilation system tailored for your home and family.

Ventilation systems have been identified as a key component in what a healthy home consists of. Condensation and excess moisture levels in a home can be a breeding ground for mould, bacteria and mildew. By controlling the amount of moisture in your home it will not only make it easier to heat, saving you money on your power bills, but change the breeding environment of unwanted bacteria.

Our friendly, home energy assessors offer free advice on the best ways of controlling the environment in your home to ensure that condensation, excess moisture and unwanted odours are minimised all whilst promoting the benefits of air purity.

Heat Transfer Systems (Transferring heat from one room to another)

Do you have a good heating source in your main living area (such as a wood burner), which heats the area very efficiently but not the rest of your home? Then installing a heat transfer system may be what you need.

By transferring excess heat from the main heating source to other targeted areas of your home such as bedrooms or a rumpus room you can achieve a more even temperature throughout your home. As a result this will reduce overheating in that main living area making it a more comfortable place to relax and entertain.

Our Heat Transfer systems can be installed as a stand-alone feature or can be paired with our SAYR Ventilation system.

What does the system consist of?

Touch Screen Control Panel

Our systems comes with an Intelligent control panel, featuring SMS (smart management system) fully automated with 3 x sensors, 1 in the ceiling cavity, 1 in your home at the control panel and one located to the exterior.
Using a micro-processing control system the controller communicates with either an individual fan or a series of fans situated in the ceiling cavity. Set and Forget!

Fan Motor

Ceiling vents

Our 150mm round vents are specially designed to direct airflow where it is needed. They sit flush with your ceiling making them unobtrusive to your décor. Our systems are individually configured for each house and airflows are designed for each room.


Our hospital grade F7 filters are treated with anti-microbial agents to destroy pollutants on contact. The air after leaving the filter is cleaner and fresher than the air currently entering your home.

Fire Retardant Ducting

Our ducting is specially constructed to withstand the temperature extremes found in your roof cavity ensuring long lasting performance.

Extraction Fans

If condensation and moisture are a problem in your home it makes sense to target the areas in your home where most of the moisture is generated – your bathroom and kitchen.

By installing a high quality extraction fan into these service rooms it can dramatically lower the moisture content in your home making it dryer and a much healthier place to live.

With the assistance of local manufacturers we offer a ducted in-line fan that is designed specifically for exhaust and supply applications. They can be also be used as part of a room to room hot-and-cold air transfer systems.
