How do you fill a forced hot water heating system?

Open a vent valve to purge the air and open the supply valve to let in water. Every hydronic (forced hot water) system has a system fill or supply valve, often connected to domestic cold water through a flow-check valve and a pressure-reducing valve. However, simply opening this valve with the rest of the system closed will merely pressurize the system with air. The system should also have one or more automatic air vents, plus a purging valve or two. By allowing air to vent (often out the top) and air bubbles to pour out through the purge valves, you can mostly fill the hydronic system with water. As the system is then heated, more air bubbles will form from dissolved air and be vented by the automatic vents. If it is not automatically vented, the top-most loop of the system may accumulate air and stop working until it is purged by opening a vent until water comes out.
