If you have a heat only or system boiler, your hot water will be stored in a cylinder. Once the water has reached the temperature you have set, a cylinder thermostat will turn off the heat supply from the boiler.
You should set the cylinder thermostat at between 60ºC and 65ºC which is hot enough to kill off harmful bacteria in the water, but is also hot enough to scald. For extra safety, ask your heating engineer to consider installing a thermostatic mixing valve which will automatically ensure that the hot water you draw off at the tap is at a safe temperature.
If your hot water cylinder or tank is well insulated, you may find that the morning's hot water stays hot enough to use in the evenings.
