CitiPower Pty A. Water heating, shower, bath and taps

What is your shower’s hot water flow rate? (2) How do you shower and bathe?
Is there insulation (lagging) on your hot water pipes?

Lagging on cold and hot pipes
Powercor Australia Ltd
If you need a new hot water heater, look at solar or 5star gas systems Australian Standards require hot water heaters to be set at no less than 60ºC. Instantaneous gas water heaters can be set to lower temperatures. Internal thermostats require adjustments by a qualified tradesperson. Set thermostats between 6065ºC. Turn off your system (including the pilot light) when you go on holidays Install a AAA rated shower head.
A bath can use over 100 litres of water. A short shower can use less than 30 litres Insulate exposed copper pipes with rubber tubing (lagging) which reduces heat loss before it gets to the where you use it. Pipes that are too hot to touch require lagging Total = / 11
If you don’t know your thermostat setting place a thermometer under running hot water closest to the water heater, then add 3 degrees if you don’t have lagging. This will tell you how hot the water is within the heater before it gets to your taps Capture water in a bucket in ten seconds, and then multiply the volume by six. Remember to use the water on your garden

Powercor Australia Ltd
Most of the energy used in washing clothes comes from heating the water. Change to a cold water powder/detergent. If you need a new washer choose an energy efficient unit with a cold water option. Fill your washing machine up with water from a tap and bucket before turning it on. Install aqualocks and tap aerators on washing machines. Front loaders are best Use the dryer less. Use an extra spin dry before using the dryer. If you need a new dryer choose an energy efficient unit Total = / 4

Consider a solar pool heater and blanket. Keep filters clean. Salt water chlorinators can double energy use
Waterbeds are very costly to run. Make your bed each day to reduce heat loss if electric blankets are on timers. Turn blankets off as you go to bed Choose microwave and gas cooking. Ensure ovens have good seals. Place lids of saucepans and pots Appliances with standby modes are still using electricity. Turn these appliances off at the wall when not in use or install timers Most modern computers can bet set onto a ‘sleep’ mode when not in use for a period of time. Turn computers off at the wall when not in use. Screen saver does not save energy Total = / 7
