What regulates the output of an immersion electric boiler?

The output of an immersion electric boiler is regulated primarily by the amount of current flowing through the heating elements. In an electric boiler, the heating elements are responsible for converting electrical energy into heat, and the rate at which they do this is directly correlated to the amount of current passing through them.

When the current increases, more electrical power is supplied to the heating elements, resulting in greater heat production and a rise in water temperature. Conversely, if the current is decreased, the output of heat generated will also decline. This relationship highlights the mechanism of direct heating within electrical immersion boilers, where the control of current allows precise regulation of temperature outputs, ensuring effective and efficient operation based on demand.

While temperature settings, pressure settings, and water level in the tank play essential roles in the overall operation and safety of the boiler system, they do not directly control the output in terms of heat generation like the flow of current does. Temperature settings typically serve as a reference point for what the user wants to achieve, and the boiler system will adjust its operation accordingly, often by modulating the electrical current.
