ASME - International Boiler and Pressure Vessel Code
How to Set Hot Water or Steam Heating System Pressure
The operating pressure of a heating boiler (hot water or hydronic heat) is read at the pressure and temperature gauge (see above) and controlled by. The starting or "cold water" pressure at the boiler - typically at 12 psi is for typical U.S. / Canadian residential
- Installation, maintenance, repair, and modification of equipment such as coal, gas, oil fired heaters and hot air furnaces, high and low pressure steam boilers, hot water boilers, power generating equipment, and similar systems (see Job Grading Standard for Heating and Boiler Plant Equipment Mechanic, 5309);

What is the safe pressure for a hot-water-heating system?
Jan 19, 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
Dec 19, 2009 · The guidelines for water quality control of water/steam in boiler plants of 60 kg/cm2 and above are furnished as recommended by many boiler designers. The feed water limits. For drum operating pressure kg/cm2 (g) 61-100, 101-165, and 166-205 with PO4 treatment type of boilers: Hardness, in ppm, has to be nil for all pressures. pH at 25oC for Cu alloy pre boiler system plants has to be between 8.8-9.2
