May 05, 2016· Bleed the system pressure down somewhere near the boiler. Then test the heating system by turning the T-stats up, and verify that all radiators/baseboards get hot. If they all get hot, turn the shut off valve completely off and monitor the system pressure for a few days. If it's stable it's likely that the auto-fill valve seats aren't sealing.

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'.

How to Care for Your Hot Water Heating System - dummi

Most hot water systems have a single gauge that measures three things: pressure, temperature, and altitude (the height of the water in the system). Monitoring the pressure is important. Most boilers run with only 12 to 15 pounds of pressure. The boiler can become seriously damaged and even dangerous if the pressure exceeds 30 pounds. Regularly monitoring the pressure is probably all you ever need to do to …
