New York Low Pressure Boiler COF Test 2025 – 400 Free Practice Questions to Pass the Exam

For an electric boiler to be operational, it is essential that it is connected to a power source. Electric boilers rely on electricity to heat the water or steam, and without a proper power connection, the unit cannot function. This connection typically involves a secure electrical supply that meets the boiler's voltage and amperage requirements, allowing it to operate effectively and safely.

While having a working safety valve and visible gauge glass are critical safety features for a boiler, they do not determine whether the boiler can operate. These components are important for maintaining safe operations but do not enable the boiler to function without the necessary electrical supply. Additionally, the size of the boiler, such as being over 1100 kW, does not affect its operational status regarding its connection to power. Therefore, being connected to a power source is the fundamental requirement for any electric boiler to be considered operational.
