Central Heating System is a system in which heat is supplied to areas of a building through a network of pipes or ducts from a central unit.

A "central heating system" in the travel, transport, and hotel context is a system that uses a central source of heat, such as a furnace or boiler, to distribute heat throughout a building or vehicle. The system typically includes a network of pipes and ducts that carry hot water or steam to radiators, baseboard heaters, or other heat-emitting devices located in different rooms or areas of the building or vehicle.

For example, in a hotel, a central heating system might be used to keep guest rooms warm and comfortable during the colder months. The system would include a boiler or furnace in a central location, such as a basement or mechanical room, and a network of pipes and ducts that carry hot water or steam to radiators or other heat-emitting devices located in the guest rooms.

In transportation, central heating systems are common in trains, buses, and ships to heat the interior of the vehicle and keep the passengers comfortable, especially in colder climates or during winter time.

Central heating systems are efficient, reliable, and easy to control, and they are especially useful in large buildings or vehicles where it would be difficult to heat each room or area individually. They also often have thermostats that allow the temperature to be controlled remotely, which can be convenient for hotels or transportation companies.
