Water heater replacement cost by type.
Installed prices for Webster Groves, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Webster Groves, where the median home was built in 1951, water heater replacement is a common upgrade. Local installed prices for a tank gas unit range from $750 to $1,850, while tank electric runs $850–$2,100. Tankless models cost $1,400–$3,300+, and heat pump units $1,700–$3,700. Because Missouri has no statewide code, Webster Groves follows the International Plumbing Code, and permits are required. An expansion tank is needed on closed systems. With cold winter inlet water and mostly gas heating, a gas water heater is recommended. The federal 25C tax credit offers 30% (up to $2,000) for qualifying heat pump units.
