Water heater replacement cost by type.
Installed prices for Wauwatosa, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Wauwatosa, where the median home was built in 1953, water heater replacement is a common upgrade. With cold winters and cold inlet water, a gas tank water heater is a strong fit for most homes. Typical installed costs range from $800 to $2,000 for a gas tank unit, $900 to $2,200 for electric tank, $1,500 to $3,500+ for tankless, and $1,800 to $4,000 for heat pump models. Wisconsin requires a permit for water heater replacement, and only owner-occupants or licensed plumbers may perform the work. The state plumbing code (SPS 382-387) applies, and an expansion tank is required on closed systems. The federal 25C tax credit offers 30% back (up to $2,000) for heat pump water heaters, but gas remains the recommended choice due to local energy availability and climate.

Recommended unit for Wauwatosa
Given Wisconsin’s cold northern climate and gas water heating, high-efficiency gas is the sensible default for most Wauwatosa 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.
