We have a large kettle in the staff eating area which is frequently left on to boil all day even when hot water is not needed. The main reason for this is that if someone forgets to switch it on before tea or lunch break, then no one gets hot drinks, so it's just easier to leave it on all the time. The trouble is that it's a 3kW kettle so if it's left on all day when no one needs it, that's a real waste of energy!

The answer to this problem is to put the kettle on a timer like this one, so that it switches itself on before break times start and off again when break times are over. That way everyone gets their hot drinks and no energy is wasted. This timer can be programmed to come on and off exactly when needed making it ideal for items that must be on at certain times or things that people tend to forget to switch off.
