Lower water-heater temperature
17% of members are saving with this action!
Save up to 300 kg / 660 lbs CO2 and up to $30 per year!
In the average home, the hot water heater is set much higher than is necessary or desired. Many homes have it set well over 55C or 140F but water this temperature is never actually used. In the shower or sink it's normally mixed with cold water. Most people are happy with water under 45C or 120F, which will save a good amount of CO2 emissions and money.
