Steam Heating Systems - Classifications

Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc. This tool provides a comprehensive classification of steam heating systems by pressure, condensate return method, and pipe layout.

Classification Type	Category	Description	Typical Application
Pressure	High Pressure	Above 20 kN/m² (3 lb/in²)	Industrial processes, large facilities
Pressure	Low Pressure	Up to 20 kN/m² (3 lb/in²)	Building heating, small facilities
Pressure	Vacuum	Below atmospheric pressure	Specialized heating systems
Condensate Return	Gravity	Condensate returns by gravity flow	Downflow systems, lower floors
Condensate Return	Mechanical	Condensate return via pump	Upflow systems, higher floors
Pipe Layout	One Pipe	Single pipe for steam and condensate	Simpler systems, lower cost
Pipe Layout	Two Pipe	Separate pipes for steam and condensate	More efficient, larger systems
Pipe Layout	Up-Feed	Steam flows upward through pipes	Upper level distribution
Pipe Layout	Down-Feed	Steam flows downward through pipes	Lower level distribution
