A contractor quoting a water heater installation in Carter County starts with the fuel the house already runs. Bottled, tank or LP gas heats more occupied homes in Carter County, Montana than any other fuel, at 70.0% (2020-2024 ACS 5-year). That share means LP gas venting, combustion air requirements, and gas line sizing are the norm a replacement has to fit. A unit spec'd for a different fuel type requires different connections, different venting, and in some cases a different location. The contractor prices the correct appliance for the infrastructure that is already there.

Ductwork laid for an older system and electrical service sized for a smaller load are what a contractor prices around first in Carter County. Half the homes in Carter County, Montana were built in 1975 or earlier (2020-2024 ACS 5-year). That means the building itself, not the new unit, sets the terms of the job. A contractor pulling permits here opens walls and chases lines to find out what the existing configuration will and will not carry before a quote is possible.
What Gets Installed With a New Water Heater

The storage tank is the piece a homeowner notices first. It sits in a utility room, basement, or garage and holds a supply of heated water ready for use throughout the house. Attached to the tank are the inlet and outlet connections, which route cold water in and hot water out to every fixture and appliance.
The pressure relief valve mounts directly on the tank and opens if pressure inside climbs too high. A drain valve sits near the base. The flue or exhaust vent runs from the top of a gas unit up through the wall or roof, carrying combustion gases out of the living space.
The drawing shows the general layout of a water heater system, and a licensed contractor determines exactly what applies to this house.
