Parts listed for sale include heat exchangers, refractories, gas valves and aquastats. Also listed are pilot assemblies, ignition modules, relays and limit switches.
Boiler models can come in several fuel types, including natural gas, propane and fuel oil. Oil burning units need higher maintenance than gas burning styles. Regular attention should be given to the blower and oil filter. A boiler is more complex than a conventional forced air furnace. They need more parts to create and manage the heating process.
