Sizing a boiler for a Teton County home is not a standard calculation. The burner, heat exchanger, and ignition system run through the bulk of the calendar year, cycling repeatedly across a long cold stretch. Homes in Teton County, MT run heat about ten months a year, from September through June. A contractor has to establish the actual heat loss of the house before quoting, because a unit that is undersized for this load runs at high duty cycles, and the heat exchanger carries the consequences. Poor installation tolerates less here than it does somewhere the equipment sits idle most of the year.
Ductwork laid down for a system that no longer exists is what a contractor opens the walls to find in much of Teton County. Half the homes in Teton County, Montana were built in 1962 or earlier (2020-2024 ACS 5-year). When a house has been through several heating systems over its life, the ducts have been adapted each time, sometimes well and sometimes not, and a new boiler installation has to work with whatever that history left behind. A contractor quoting a job here prices the duct condition as seriously as the unit itself, because a trunk line that cannot carry the required distribution will undercut any equipment installed on it.
What Gets Installed With a New Boiler
The boiler itself sits in a mechanical room, basement, or utility closet and is the unit that heats water for the whole system. From there, a network of pipes runs through the house, carrying that heated water to radiators or radiant floor loops in each room.
The radiators or floor manifolds are what the homeowner sees and feels in the living spaces. An expansion tank, usually mounted near the boiler, absorbs pressure changes as water heats and cools. A circulator pump, also close to the boiler, moves water through the loop.
The drawing shows a typical boiler layout, and a licensed contractor determines which components and configurations apply to your home.

Licensing and Legal Requirements in Teton County, Montana
Montana’s contractor licence does not reach a casual, minor or inconsequential job whose total price for labour, materials and everything else is less than $2,500 — and the exemption is lost if the work is only part of a larger operation, or if a job is divided up to get under the figure.
Montana requires a current construction contractor licence from the Department of Labor and Industry: an individual or business may not engage in business as a construction contractor without one.
Severe Weather in Teton County
Boiler systems in Teton County work against the local climate, and that climate is not the same as anywhere else in Montana. How hard the weather pushes here shapes what a boiler needs to handle and how well it has to be installed to handle it.
