The Braemar 7 Star ducted gas heater! Launched in March 2015, the Braemar 7 Star ducted gas heater has the highest star rating and is the most efficient conventional ducted gas heater in the world! The 7 star heater has shifted the paradigm of the star rating system in Australia, as the current rating system only offers a maximum of 6 stars, encouraging the Australian Gas Association (AGA) to reconsider the rating system. It represents a major breakthrough for the industry, significantly reducing energy usage and the impact on the environment. The key features include a cost saving of $577 per year and a reduction in CO2 emissions of 1.99 tonnes per year compared to a 3 star ducted gas heating model.
