What provision must be made for auxiliary heating systems?

The requirement for auxiliary heating systems to have an alternate source of electric power is crucial for ensuring safety and reliability, especially in situations where the primary heating source may fail. This provision ensures that even during power outages or failures in the primary heating system, there is still a reliable means to maintain heat in a building, which is essential for occupant safety and comfort.

In colder climates, maintaining adequate heating is vital to prevent health risks associated with low temperatures, such as hypothermia or damage to plumbing systems from freezing. By having an alternate source of electric power, such as a generator or a connection to an uninterrupted power supply, facilities can remain operational and comfortable regardless of external electrical issues. This is particularly important in critical environments like hospitals or care facilities where the risks associated with losing heating can be even more severe.

The other options presented do not meet safety and operational needs in the same way. Encouraging the use of space heaters could lead to misuse and increased fire risk. Prohibiting alternative fuels would limit the options for heating and resilience against energy supply disruptions. Lastly, stating that no emergency heating is required undermines the essential need for maintaining safety and warmth during emergencies. Therefore, the necessity for an auxiliary heating system to have an alternate source of electric power
