My man explained the hot water cylinder to me in not so technical language. It’s the same principle has a pot on the stove. If you start with cold water you have to turn your stove up high to get the water boiling, but when its there you can turn it down to the lowest setting and keep it simmering. When you turn off your hot water cylinder the water cools down so the cylinder has to work on full power to get it hot as quick as possible – this uses more power than the “simmer” function of leaving the cylinder on all the time. We turn our cylinder off if we go a away for 3 nights or more.
