Water heater replacement cost by type.
Installed prices for Central Islip, adjusted for local labor. Larger tanks and code upgrades move the number up.
Central Islip homeowners replacing a water heater typically pay between $800 and $4,000, depending on the type and complexity. With a median home age of 57 years, many homes have older plumbing that may require updates during replacement. New York State requires a permit for water heater replacement, and in Central Islip, a Licensed Master Plumber must pull the permit and perform the work.

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