Sizing a boiler for Pierce County is not a calculation a contractor can run off a national chart and call finished. Homes in Pierce County, ND run heat about nine months a year, from September through May. A burner cycling through that kind of sustained demand puts cumulative stress on the heat exchanger and ignition system that a loose or generic install accelerates. The contractor has to establish the actual heat load of the house before committing to a unit, because a boiler that runs undersized in a season this long will show its failure modes in the heat exchanger long before a correctly commissioned unit would.

Older ductwork does not fail the way a unit fails. It narrows, splits, or runs in configurations sized for whatever the house originally heated with, and a contractor quoting a boiler installation has to trace what is in the walls before a unit goes on the truck. Half the homes in Pierce County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). That means a significant share of the houses a contractor walks into here carry duct layouts that were never designed for the system about to replace them, and the routing questions get answered on site, not in advance.
What Gets Installed With a New Boiler

The boiler itself sits in a mechanical room, basement, or utility space and is the unit that heats water and sends it through the house. Alongside it, the expansion tank mounts to the piping nearby and absorbs pressure changes as water heats and cools. The circulator pump, also close to the boiler, moves the heated water through the system.
Radiators or baseboard convectors mount along the walls of each room and release heat as hot water passes through them. The thermostat goes on an interior wall and tells the boiler when to fire. Supply and return piping runs between all of these pieces, carrying water out from the boiler and back again.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home.
