Sizing a boiler for a Lane County home is not a back-of-the-envelope job. Homes in Lane County, OR run heat about ten months a year, from September through June. A burner and heat exchanger cycling through that kind of sustained demand accumulate wear on every component that fires and quenches: the ignition system, the heat exchanger seams, the circulator. A contractor quoting a replacement has to account for what the existing system was actually asked to carry, because an undersized unit will run harder and fail earlier here than the same unit would somewhere a heating season is briefer. The load calculation has to be right before anything else gets priced.
Ductwork sized and routed for an older heating system can force a contractor to reroute runs, add zones, or tell a homeowner the existing layout will not serve the new unit at all. Half the homes in Lane County, Oregon were built in 1977 or earlier (2020-2024 ACS 5-year). That puts the distribution side of the job, not the boiler itself, at the center of what a contractor has to assess and price before anything else gets ordered.
What a Boiler Installation Puts in Your Home
The boiler itself sits in a mechanical room, basement, or utility closet and is the unit that heats water for the whole system. Wall-mounted or floor-standing depending on the house, it connects to a flue or exhaust pipe that runs through an exterior wall or up through the roof to vent combustion gases outside.
From the boiler, a network of pipes carries hot water to radiators, baseboard units, or radiant floor loops placed throughout the living space. A circulation pump moves water through those pipes, and an expansion tank mounted nearby absorbs pressure changes as the water heats and cools.
The drawing shows a typical layout, and a licensed contractor determines exactly which components and configurations apply to your home.

Oregon’s contractor licence does not reach casual, minor or inconsequential work on one structure where the person’s contracts total less than $1,000 — and the exemption is unavailable to anyone who advertises or signs themselves as a contractor, at any price.
