What does a ‘Boiler Efficiency Rating’ mean?

To rate, or not to rate? In Australia there is currently no rating system for Heating Boiler efficiency, and there is unlikely to be for several years to come. So how do you know if you are buying an efficient heating boiler or not? For this reason, we refer to the ‘SEDBUK’ rating system used in Europe. ’SEDBUK’ is the accepted standard for the UK and Europe (Stands for ‘Seasonal Efficiency of a Domestic Boiler in the UK’) and effectively measures a boilers efficiency.

The lack of an Australian Heating boiler rating is made even more confusing for consumers as ‘Domestic Hot Water Boilers’ do have a rating system (they use the AGA Star Rating system), it is only ‘Heating Boilers’ that do not, hence the SEDBUK system is the best (and only) reference for Heating Boiler Efficiency. As the space heating boiler market is relatively small in Australia compared to Europe the legislation and procedure has not yet been put in place by the government.

So what does this mean to the consumer? A lot. It means the consumer has to be extremely diligent in boiler selection to ensure the greatest efficiency. BAXI boilers are the most efficient Heating Boilers for sale in Australia and are amongst the most efficient in the world.
