An immersion heater is a device that is used to heat water in a tank or container. It is typically used to heat water for bathing, washing dishes, or other purposes. Immersion heaters are relatively simple devices, but they can be dangerous if they are not used properly. It is important to check an immersion heater regularly to make sure that it is working properly and that it is not a safety hazard.
There are a few different ways to check an immersion heater. One way is to simply turn it on and see if it heats the water. Another way is to use a multimeter to check the electrical continuity of the heater. If the heater is not working properly, it may need to be replaced.
