Look for the money-saving stars on gas hot water systems
Electrical appliances are not the only things with energy-rating stars. Gas hot water systems have them too.
Gas labels give you a star rating for energy efficiency – they also give you the annual energy consumption of the product with a MJ (megajoules) per year figure. You should look out for appliances that have a maximum number of energy-rating stars and the lowest MJ figure.

When buying a gas hot water system, buy a system with a minimum 5-star rating.
