How to Care for Your Hot Water Heating System - dummies

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 …
