Does the heating have to be on to have hot water?
It’s better to leave the hot water heater on all the time, rather than turning it on and off. This is a very common myth. But in fact, you really don’t need to be heating your water all the time. Your immersion heater or boiler will heat up hot water which is stored in a tank.

How does an electric hot water heater work?
Electric water heaters have an upper and lower element, and the lower element is the one responsible for doing most of the heating. Whenever you turn on the hot water, cold water is pushed to the bottom of your tank and is heated by the lower element. As it rises to the top, the upper element keeps that water at a decent temperature.
Why does my water heater not have enough hot water?
Again, if you don’t have enough hot water, the reason why will depend on the type of heater you have. If you have a heater with a tank, it may simply be that your tank is not big enough for your requirements. If your tank is too small for the number of people showering, for example, you may use up all the hot water before everyone is finished.
What happens when you turn on a storage water heater?
When you turn on a faucet in a house equipped with a storage water heater, the water heater releases hot water from the top of the tank and sends it through the pipes to your sink, shower or bath. The tank is then replenished with cold water, so the tank always stays full.
