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

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 Efficiency | How to balance steam load

2011-8-26·Hence, efficiency as a percentage of boiler duty will be smaller at higher loads, and vice versa. The flue gas losses on the other hand will be greater at greater loads as the exit gas temperature is greater at greater loads and decreases as the load decreases. The combination gives a somewhat flat or parabolic performance curve (Figure 3).
