Water heater replacement cost by type.
Installed prices for Hudson, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Hudson, Massachusetts, water heater replacement costs typically range from $750–$1,850 for tank gas, $850–$2,000 for tank electric, $1,400–$3,200+ for tankless, and $1,650–$3,700 for heat pump units. With a median home built in 1968 and cold winter inlet water, many older homes require upgrades to meet the Massachusetts State Plumbing Code (248 CMR), including expansion tanks on closed systems (required since 2010). A permit from the town is mandatory, and work must be done by a licensed plumber or gas fitter. Given the region's cold climate and mostly gas heating, heat pump water heaters are a strong fit for energy savings, especially with the federal 25C tax credit covering 30% of cost up to $2,000.

Recommended unit for Hudson
Given Massachusetts’s cold northern climate and gas water heating, heat-pump (hybrid) is the sensible default for most Hudson 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.

Water Heater Replacement in Hudson, explained.
What affects water heater replacement cost in Hudson
Labor rates reflect the local market and the need for a licensed plumber/gas fitter. Permit fees vary by town but are required. The age of your home (median 1968) may mean additional work to meet current code, such as installing an expansion tank on a closed system. Unit type also drives cost: heat pump models are more expensive upfront but qualify for federal tax credits, while tankless units require venting upgrades in older homes. Winter inlet water temperature can affect sizing and performance.
