What is the safe pressure for a hot-water-heating

A member of the Wall community asks this question: What is the "safe" operating pressure in PSI for a hot-water boiler heating system, and what is the "safe" range in terms of temperature for boiler operation? One member responds: The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi.

Boiler Pressure - an overview ScienceDirect Topics

Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II3.6.6-1). For the steam generator plant with low steam pressure (below 40 kgcm 2), the requirement of a condensate polishing unit is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through feedwater
