Water heater installation cost by job.
Installed-labor pricing for Westminster, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Westminster, Maryland, typically costs between $700 and $1,550 for a standard tank unit, and $1,550 to $3,800+ for a tankless system. With a median home age of 44 years, many homes require updates to meet current code, including an expansion tank on closed systems. All work must be performed by a Maryland-licensed master plumber and undergo a final local inspection. Given the cold winter inlet water and humid subtropical climate, a heat pump water heater is a recommended choice for efficiency, and the federal 25C tax credit can offset 30% of the cost up to $2,000.
