Water heater replacement cost by type.

Typical installed prices range from $800–$2,100 for a tank gas unit, $950–$2,300 for electric, $1,550–$3,600+ for tankless, and $1,850–$4,100 for a heat pump model.

Recommended unit for Waterbury
Given Connecticut’s cold northern / humid continental climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Waterbury 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.
