Generated explanation

The illustration shows a diaphragm expansion tank connected to the hot-water supply piping of a hydronic heating boiler. An enlarged cross section shows a rubber membrane separating the air chamber above from the water chamber below, with a valve at the top for pressurizing the air side. The tank's water-side connection enters at the bottom. The boiler diagram also shows red hot-water supply piping, blue cold-water return piping, an exhaust flue, and associated valves.
