Water heater installation cost by job.
Installed-labor pricing for Annapolis, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Annapolis, where the median home was built in 1974, many water heaters are due for replacement. A standard tank installation typically runs $800–$1,800, while tankless models cost $1,800–$4,600+. Because Maryland requires a licensed master plumber to perform the work and a final inspection, labor and permit fees are built into these estimates. The humid subtropical climate and cold winter inlet water make heat-pump water heaters a strong fit, especially with the federal 25C tax credit covering 30% of the cost (up to $2,000).

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

What drives installation costs in Annapolis?
The age of your home (many are 50+ years old) can affect venting or gas line upgrades. Adding a new gas line for a tankless unit runs $300–$1,000.

Choosing a heat-pump model qualifies for the federal 25C tax credit, which can offset the higher upfront price.

A final inspection by the local authority is required before the unit can be used, which may add a day or two to the timeline.
