Once turned on, the heating process can take anywhere from 1.5 to 3 hours depending on the size of the cylinder and the power of the immersion heater. Ideally, the water needs to be heated to at least 50°C to kill any potential pathogens.
Correspondingly, can you leave an immersion heater on all the time?
Do not leave your immersion heater running all the time. No matter how well-insulated the immersion tank is, it will still lose heat and the drop in water temperature will cause the immersion heater to run repeatedly (like your kettle coming back to the boil over and over again).
Then, how do you know if immersion heater is working?
All you have to do is to go to the electrical panel and check if the breaker is tripped and turn back on. If you are lucky it could work again. But if not then you have an issue with the heating element. If you are an advanced DIY homeowner, you can test if the immersion heater has a 220-240 volt supply.

What temperature should my immersion heater be set at?
60°C (140°F) is the recommended minimum, as at that temperature Legionella bacteria is killed within 32 minutes. At 66°C (151°F), Legionella bacteria dies instantly. If you feel this is too hot, yet still want to be safe.
Why does it take my hot water so long to get hot?
There are several reasons; the distance from the water heater, the diameter of the piping, and the flow rate of the water. The further the hot water has to flow, the longer it takes to heat up the shower faucet.
Why does my hot water run out so fast?
This happens over time as your water heater ages. If you haven’t maintained your water heater with annual system flushes, this could be the problem. Sediment is formed from loose minerals that are found naturally in water. When they settle at the bottom of the tank, it causes your tank to run out of hot water quickly.
