Water heater replacement cost by type.
Installed prices for Mount Vernon, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Mount Vernon, Illinois, replacing a water heater is a practical investment for homes that average about 60 years old. With a median household income of $48,786, homeowners often seek a balance of upfront cost and long-term value. Typical installed prices for a gas tank water heater range from $600 to $1,550, making it a common choice given the area's reliance on natural gas.

What Affects Water Heater Replacement Costs in Mount Vernon
Prices vary based on the type of unit: gas tank models are generally more affordable than tankless or heat pump options. Labor costs reflect the need for a licensed plumber and permit fees. Older homes may require updates to venting or gas lines, adding to the total. The cold water temperature in winter can influence the choice of a higher-capacity unit. Rebates like the federal 25C tax credit (30% up to $2,000 for heat pump models) can offset higher upfront costs, but gas remains the recommended fuel type for most homes.
