Immersion heaters work exactly the same as an electric kettle.

There is at least one element inside that heats the water, controlled by a thermostat to make sure the water doesn't get too hot or boil away.

Here's a good link:

The safety precautions concern the wiring and thermostat, but this is not something the average householder worries about.
Modern British immersion heaters require a limit thermostat in case the normal temperature control fails and continues to boil the water. They can be fitted to vented or unvented water cylinders with the appropriate installation.
