How hot should my water be?

3 June 2016

Water coming out of the tap too hot can be quite dangerous, especially if you've got young children. At the same time, if the thermostat in the cylinder is turned down too low, your cylinder can become an ideal breeding ground for harmful legionella bacteria. Your home's hot water must be stored at over 60°C but not be more than 55°C coming out of the basin, bath and shower. A Master Plumber can check the temperature and give you some options for how to get it right. This could mean installing tempering valves, temperature limiting taps or shower mixers.
