A contractor quoting a water heater replacement in Indiana starts from what the house is already burning, because that decides what the new unit is allowed to be: venting configuration, combustion air supply, and whether an existing flue can stay. Utility gas heats more occupied homes in Indiana than any other fuel, at 58.6% (2020-2024 ACS 5-year). A home built around gas infrastructure has dedicated venting runs and gas supply lines sized for a particular load, and a replacement that steps outside that fuel means reworking what is already there. That additional scope changes the job before a contractor has touched the unit itself.
A quote for a new water heater starts with what the contractor can see when they open the utility space: whether the existing venting clears current code, whether the electrical circuit is sized for what you want to install, and whether the supply and drain connections are in serviceable condition. Half the homes in Indiana were built in 1976 or earlier (2020-2024 ACS 5-year). That spread across the stock means a contractor working anywhere in the state routinely finds setups that were correct when the house was built and have not been touched since. What that means for your install is specific to what is in your utility room, not to when the house was permitted.
How does your Indiana county compare on severe weather?

A water heater installed outdoors or in an unconditioned space is exposed to whatever the weather brings, including hard freezes, high wind and flooding. A county with a heavier storm record is a place where those forces show up more often over the unit's lifetime. Have a contractor check where the unit sits, how it's secured, and whether its venting and connections are protected from water and wind.
