  • Boiler Temperature/Pressure Too High? — Heating Help: The Wall

    A month ago I repeated the exercise on a different zone. Another good result. However, a few days ago I checked on a loud clacking noise coming from the valves/large diameter pipes (manifold) above the boiler. Temperature/pressure readings were much greater than I'm used to seeing - about 225 degF/22 psi. Essentially, water in the boiler was Get Price
