Recommended unit for Champaign
Given Illinois’s cold continental (humid) climate and gas water heating, high-efficiency gas is the sensible default for most Champaign homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

What affects the cost in Champaign?
The age of your home (median built 1985) can mean older plumbing that requires extra labor. Tankless units cost more upfront but may qualify for the federal 25C tax credit. Adding a new gas line adds $275–$950. Permits and code compliance (expansion tank, seismic strapping not required) also factor into the total.
Common water heater issues in Champaign
Sediment buildup
Hard water in Champaign can cause sediment to accumulate, reducing efficiency and lifespan.
Cold inlet water
Winter inlet water is very cold, making tankless units work harder and potentially requiring a larger model.
Expansion tank requirement
Closed systems (common in newer homes) require an expansion tank to prevent pressure damage.
What to expect during installation
A licensed plumber will first assess your existing setup and obtain a permit. The old unit is drained and disconnected, then the new water heater is installed, including any required expansion tank. For gas units, the gas line and venting are checked. The job typically takes 4–8 hours, and the plumber will test for leaks and proper operation.
