Regular maintenance of thermal power stations and electricity generation and distribution facilities is important for both the facility operators and maintenance providers. An unmaintained or poorly maintained facility can cause a power outage, damage or – in the worst case scenario – the destruction of the equipment built into it that is crucial for customers.

Boiler rooms are facilities where the boiler (furnace) plays a central role as it ensures sufficient heat energy for the heating of the facility and, as appropriate, also the preparation of domestic hot water. They differ with respect to the substance used for firing and the size of space they take up. The majority of boiler rooms use fuel oil, gas or solid fuels.
