Homes in Columbia County, WA run heat about ten months a year, from September through June. A boiler working that schedule puts its hours on the burner, the heat exchanger, and the ignition system, and those are the parts a contractor opens first when a repair call comes in. Seals that might last years in a shorter season crack sooner here because the equipment rarely sits idle long enough to matter. A hairline fracture in a heat exchanger found during a repair visit is a direct product of that cycling load.
Pipework and radiator loops sized for coal or early oil heat carry different pressures, different flow rates, and different fittings than a modern boiler puts into them. Half the homes in Columbia County, Washington were built in 1953 or earlier (2020-2024 ACS 5-year). A contractor opening a boiler here works out early whether the distribution side of the system is the source of the problem, because in housing this old the supply lines and zone valves have often degraded independently of the heat source itself. A part that fits the boiler may not fix the call.
The Parts of a Boiler a Contractor Checks First
The boiler itself sits in the basement or a utility room and is the piece a contractor goes to first. It heats water and pushes it through the system. When a boiler is short-cycling, leaking, or failing to reach temperature, the burner assembly, heat exchanger, and pressure relief valve are all candidates inside that cabinet.
Radiators or baseboard units sit throughout the living spaces and are where the heat actually enters the rooms. The circulator pump, usually mounted on the boiler or the supply pipe close to it, moves the water through that loop. A stuck pump, a stuck zone valve, or air trapped in the lines can all produce a room that stays cold even when the boiler fires.
The drawing shows the general layout of a boiler system, and a licensed contractor determines which parts apply and what work is needed in your particular home.

Washington requires contractor registration rather than an HVAC licence: every contractor must register with the Department of Labor and Industries, and advertising, bidding or working as a contractor without that registration is a gross misdemeanour.
