Hot water systems

Which hot water systems are most efficient?

The wrong hot water system can easily account for the lion's share of your electricity consumption. In fact, electric tank systems are being phased out. Find out how different systems compare in terms of efficiency.

Cold water diverter

Cold water diverters

In most plumbing setups, it takes a while for hot water to reach the hot tap when it's turned on. Cold water diverters recycle the cold water which would otherwise pour down the drain in this time.

Energy efficiency labels

Energy efficiency ratings for hot water

Hot water systems can chew through a lot of energy - and as a result these days they come with energy efficiency ratings to help you understand how best to choose the most efficient model.

Efficiency of different hot water systems

Phase-out of electric tank hot water systems

Electric tank storage hot water systems are notorious for the amount of greenhouse emissions they're responsible for. As a result, they're now being phased out throughout Australia.

Pipe lagging

Lagging and heat loss

See how lagging (insulation) and the distance that hot water has to travel through your pipes can affect energy efficiency in your hot water system.
