What temperature should my hot water tank be set at UK?

A domestic hot water cylinder thermostat should be set at 60-65ºC. This is high enough to kill off harmful bacteria such as Legionella. If you set the thermostat much higher than this the water that comes out of the taps will be too hot and there’ll be a risk of scalding.

What temperature should radiators be?

Typically, the common rule for radiator temperature control is to aim to have each room somewhere between 18C (64F) and 21C (70F). In most homes, these central heating settings should be comfortable, and for others, only slight adjustments would normally need to be made to achieve a preferable temperature.

Is 50 degrees hot enough for hot water?

Will 45 degree water burn you?

A water temperature of 49 to 52°C (120 to 125°F) is a reasonable compromise between a household’s need for volume of hot water and safety. At 49°C (120°F) it takes 10 minutes and at 52°C (125°F) it takes two minutes to cause full thickness burns of adult skin. A child’s skin burns in less time.
