Water heater installation cost by job.
Installed-labor pricing for Uniondale, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Uniondale, NY, a typical water heater installation costs between $800 and $1,800 for a standard tank model, and $1,800 to $4,600+ for a tankless unit. With many homes built around 1954, older plumbing and gas lines may require upgrades, adding $300–$1,000 for a new gas line.

In most cases, a Licensed Master Plumber must pull the permit and perform the work—homeowner self-installs are generally not allowed. The cold northern climate means cold winter inlet water, making an energy-efficient unit like a heat pump water heater a strong fit; it also qualifies for the federal 25C tax credit (30%, up to $2,000).

Recommended unit for Uniondale
Given New York’s cold northern / humid continental climate and gas water heating, tank or tankless is the sensible default for most Uniondale 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.
