What a contractor has to settle before quoting a replacement is how hard the existing equipment has actually been pushed, and a statewide figure only goes so far in answering that. 5,922 severe weather events were recorded in Michigan between 2015 and 2024. Spread across a state of Michigan's size, that total says a great deal about the weather the state carries and not much about the load any one system has absorbed at a specific address. Equipment in one part of the state runs against conditions that a county away look meaningfully different. A contractor reading the installation has to work out from what is in front of them, not from a number that covers the whole state at once.
A quote for a new water heater starts with what is already in the house: the condition of the existing venting, whether the electrical service at the unit will carry the load, and whether the space meets current clearance requirements. None of that can be read from a listing or an address. Half the homes in Michigan were built in 1972 or earlier (2020-2024 ACS 5-year). That means most contractors working a Michigan job will assess before they specify, because the systems already installed set the real constraints on what goes in and at what cost.

A heavier storm record means a water heater and the power and gas lines feeding it face outages, flooding and hard freezes more often. A tank that is not strapped, elevated or vented properly can take the brunt of that. Have a contractor check the shutoff valve, the venting, how the unit is secured, and the condition of the tank itself.
