Module 79: Integrating gas-fired and electrical heat …

Feb 04, 2007 · A boiler is a bit more complex than a forced air furnace in that it has more parts, valves, and controls. However, gas-fired boilers are fairly reliable and when problems do occur, they are usually related to the expansion tank or water circulation pump(s). The major components of the boiler for a hot water (hydronic) system include

Boiler Gauges, how to read the temperature & pressure

Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler
