How can I set the temperature for my hot water?

On the Home screen, select ‘More’ at the bottom of the screen. Select ‘Hot water’ and now you can adjust the temperature for your hot tap using the sliding indicator. Between 50 and 60 degrees Celsius is about right for a combi boiler, but don’t set it for lower than 60 degrees Celsius if you have a hot water storage cylinder, as this temperature will protect you from Legionella.
