Water heater replacement cost by type.
Installed prices for Hannibal, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Hannibal, Missouri, water heater replacement costs typically range from $650 to $1,550 for a gas tank unit, $700 to $1,750 for electric tank, $1,200 to $2,800+ for tankless, and $1,400 to $3,100 for heat pump models. With a median home built in 1962, many homes have aging equipment that may need replacement. The humid continental climate and cold winter inlet water mean gas water heaters are a common and efficient choice. Local permits are required, and work must be done by a state-licensed plumber. An expansion tank may be needed if your system has a check valve or backflow preventer. The federal 25C tax credit offers up to $2,000 for qualifying heat pump water heaters, making them a more affordable option in the long run.

Sediment buildup
Hard water and sediment accumulate in the tank, reducing efficiency and causing noise. Flushing annually helps extend the life of the unit.
Corrosion and leaks
Older tanks (10-15 years) often develop rust and leaks due to the age of the home's plumbing and water chemistry.
Inadequate capacity
Homes built in the 1960s may have undersized tanks for modern usage, leading to running out of hot water during peak demand.
