The Normal PSI Reading for a Hot Water Boiler System | Hunker

The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.

Basics of hot water heating boilers - Specifying Engineer

Dec 30, 2019 · To find the optimal pressures, consult the manual that came with your boiler. But if that's lost, most boilers are so similar the pressure differential between them is relatively minor. In any event, the usual cold pressure of a boiler should sit at about 12psi (pounds per square inch). Most pressure gauges display different-colored zones.

under 10 psi in hot water boiler? — Heating Help: The Wall

Given: Every 2.3 Ft of water equal 1 PSI. FORMULA: Height to baseboard 58 FT Ft of water = 1PSI 2.3 = 25.22 minimum fill pressure to get water to the top floor baseboard. To eliminate flow noise and assure that the system is completely filled, add 4 PSI to the fill. Final *cold fill = 25 + 4 or 29 PSI

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'.

To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.
