Which characteristic is essential for an electrode type boiler?

An electrode type boiler relies on the principle of electrical resistance to generate heat. For this type of boiler to function effectively, the water used must be able to conduct electricity. The electrical current passes through the water, which acts as the medium for conduction, leading to the heating of the water as it flows through the system. This characteristic is essential because if the water does not conduct electricity adequately, the boiler would not operate efficiently, and the heating process would fail.

In contrast, other aspects such as load stability, pressure consistency, or the configuration of electric elements may play roles in different types of boilers or specific operational considerations, but the fundamental requirement of an electrode type boiler hinges on the use of electrically conductive water.
