The source of heat for a DPV room must be of what type?

In a DPV (Deluge System Pump Room) room, utilizing a permanently installed type of heat source is critical for maintaining a consistent and reliable temperature. A permanently installed heat source ensures that the equipment, components, and systems within the room are safeguarded against cold conditions, which could otherwise affect their functionality or lead to failures.

This type of heat source is typically designed to operate continuously and is less likely to be moved or disrupted compared to portable or mobile types. Permanently installed heating systems can provide stable and adequate heating necessary for proper operation, ensuring that pumps and fire protection systems remain ready to function when needed.

Much less reliable options, such as portable, mobile, or temporary types, can introduce risks due to their potential for disconnection or unanticipated removal. These types may not provide the constant environmental conditions required for essential equipment, which can be detrimental in an emergency situation where reliable operation is critical.
