Gas-fired water heaters run on combustion, and the venting and air-supply arrangements that serve one unit do not automatically suit another. Utility gas heats more occupied homes in Wheatland County, Montana than any other fuel, at 51.0% (2020-2024 ACS 5-year). That majority shapes what a contractor has to verify before any replacement goes in: whether the existing flue can handle the draft requirements of a new appliance, and whether the space around it draws enough combustion air. Get either wrong and the unit runs short of air or back-drafts exhaust into the house. A contractor quotes the appliance and the venting together, because in a gas-dominant market the two are the same job.

Ductwork in much of this county's housing was put in for systems that no longer exist in those houses, and what a contractor finds when they open the walls is infrastructure that has been patched to fit successive replacements rather than built for any one of them. Half the homes in Wheatland County, Montana were built in 1958 or earlier (2020-2024 ACS 5-year). A water heater installation here asks whether the existing supply lines, venting path, and electrical service match what the new unit actually requires, and the answer comes from what is in the house, not from the permit date. Those conditions vary house to house, which is why a contractor prices the job after the walk-through.
What a Water Heater Installation Covers

The tank or tankless unit is the heart of the system. A storage tank sits in a utility closet, basement, or garage and holds a ready supply of hot water. A tankless unit mounts to a wall in the same spaces and heats water only when a tap opens.
A pressure relief valve attaches directly to the tank and releases if pressure inside climbs too high. Cold supply lines bring water in, hot lines carry it out to every fixture, and a dedicated gas line or electrical circuit feeds the burner or heating element that does the actual work.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific home.
