1000 Flowers for the Planet - #267 Reduce Hot Water Temperature
Most hot water systems are set to 140° but turning the thermostat down to 120° will still give you water that’s plenty hot enough. Even if you turn it down to 130° you are still going to be making some savings. Read through your hot water service manual before making any changes, check if there are two elements in your system which means you’ll have two thermostats, and ensure your safety at all times. By turning down the thermostat you will reduce the risk of scalding, which can occur at 140°, you’ll save money, you will reduce energy use, saving fossil fuels and reducing carbon emissions, and when lots of people make these small changes it makes a big difference to the planet.
