What is the difference between heat exchange station and gas boiler room?

Heat exchange station and gas boiler room are completely different individuals. Gas-fired boiler room is a place where water (or other medium) is heated with fuel to certain parameters. Gas-fired boiler room is a place where heat source is produced. Its main equipment includes boiler, blower, induced draft fan, circulating pump, and various auxiliary equipment (water treatment), among which boiler is the main part.

The purpose of the heat exchange station is to convert the high-temperature hot water (higher than 100℃) produced by the gas boiler room into hot water (lower than 100℃) that can directly supply heat to users. It is a transit station, with a large space, mainly for stations.
