All
gas hot water systems (except gas boosted solar hot water systems)
display energy labels with star ratings for energy efficiency. Electric
hot water systems currently do not carry energy rating labels.
The more stars (six is best) the less gas used and the lower the operating
costs. This also means reduced greenhouse gas emissions. Rating labels
will also tell you the expected annual energy consumption in megajoules
(MJ), based on a consumption of 200 litres of hot water per day. To
convert MJ to kWh units as on your gas bill divide by 3.6.
To compare the energy ratings of various gas hot water systems, visit the
Australian
Gas Association's web site and look for the 'Directory of Certified
Gas Appliances and Components'. This directory is produced on a yearly basis
and contains information on the annual energy consumption and star ratings
for particular gas appliances, including household hot water systems. |
