Water heater installation cost by job.
Installed-labor pricing for Marlton, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Marlton, Maryland, water heater installation costs typically range from $750 to $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless system, plus $275–$950 for a new gas line if needed. With a median home built in 1989, many homes have older units that may require code updates. Maryland requires a permit and a licensed master plumber for installation, with final inspection covering T&P discharge, venting, and connections. Given the humid subtropical climate and cold winter inlet water, a heat pump water heater is a strong fit for energy efficiency, though upfront costs are higher. The federal 25C tax credit offers 30% back (up to $2,000) for qualifying heat pump models, but no state-level rebates are currently available through EmPOWER programs.

Maryland code requires an expansion tank on closed systems (with check valve, PRV, or backflow preventer). Many older Marlton homes may lack one, adding to installation cost.
Permit and inspection delays
