Troubleshooting a Gas-Fired Hot Water Boiler

The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure. If there is no pressure-reducing valve, you can manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi.

Boiler Feed Water System Diagram and Explanation - What is

A open feed system is found in a system with an auxiliary boiler, which is generally on a ship with a diesel engine. In an open feed system, steam from various systems comes to the condenser and gets converted into water. This condenser is continuously circulated with sea water and operates under certain atmospheric pressure or slight vacuum
