Water heater installation cost by job.
Installed-labor pricing for Crofton, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Crofton, Maryland, water heater installation costs typically range from $800 to $1,800 for a standard tank unit and $1,800 to $4,600+ for a tankless system, with an additional $300–$1,000 for a new gas line if needed. With a median home age of 37 years and a humid subtropical climate, many homes have older units that may need replacement. Local code requires a permit and inspection by a Maryland-licensed master plumber, and an expansion tank is mandatory on closed systems. Given the area's moderate climate and inlet water temperatures, a heat pump water heater is a strong fit for energy efficiency, though upfront costs are higher. Federal 25C tax credits (30%, up to $2,000) apply to qualifying heat pump models, but no state-specific rebates are listed here.

Recommended unit for Crofton
Given Maryland’s humid subtropical climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Crofton 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.
