Water heater replacement cost by type.
Installed prices for Madison, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Madison, Wisconsin, water heater replacement costs vary based on unit type and installation complexity. Typical installed prices range from $900–$2,300 for a tank gas unit, $1,050–$2,500 for tank electric, $1,700–$4,000+ for tankless, and $2,100–$4,600 for a heat pump model. Because Madison has cold winters and cold inlet water, a gas water heater is a recommended choice for its efficiency and recovery rate. Local permits are required under Wisconsin state plumbing code (SPS 382-387), and only owner-occupants or licensed plumbers may perform the work. The federal 25C tax credit offers up to $2,000 for heat pump water heaters, but gas units do not qualify. Labor costs reflect local rates and the need for code-compliant installation, including expansion tanks on closed systems.

What affects water heater replacement cost in Madison?
Prices vary by unit type: gas tank models are generally more affordable than tankless or heat pump units. Installation complexity—such as venting for gas units or electrical upgrades for heat pumps—can increase costs. Local permit fees and the need for an expansion tank on closed systems add to the total. In Madison’s cold climate, a gas unit’s higher recovery rate may be preferred, but heat pumps offer long-term energy savings with the federal tax credit.
