Sizing a boiler for this address takes more than picking a unit that covers the square footage. Homes in Teton County, WY run heat in every month of the year. The burner, heat exchanger, and ignition system never get a long off-season to sit idle, which means a poorly sized unit cycles harder and reaches component limits faster than the same unit would in a place that shuts heating down for months at a stretch. A contractor quoting a replacement here will want to establish whether the previous system was correctly sized before settling on what goes in next, because an undersized boiler in this county runs near its ceiling constantly.

Ductwork laid down for an earlier system carries assumptions about airflow, routing, and load that may not match what a new boiler requires. Half the homes in Teton County, Wyoming were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor installing a boiler in a house from that era has to assess whether the existing distribution can carry what the new unit puts out, and in many cases the answer reshapes the scope before any equipment is ordered. The boiler itself is straightforward to spec. What takes the work is the structure it has to run through.
What Gets Installed With a New Boiler

The boiler itself sits in the basement, mechanical room, or utility closet and is the unit a homeowner would walk past every day without thinking much about it. It heats water and sends that water out through the home's piping. A contractor sets it in place, connects it to the fuel supply, and ties it into the existing or new distribution lines.
Radiators or radiant floor loops are the delivery points spread through the living spaces, and each one receives hot water from the boiler and releases heat into the room. A circulator pump, mounted close to the boiler, keeps water moving through those lines. An expansion tank sits nearby to absorb pressure changes as the water heats and cools.
