Water heater installation cost by job.
Installed-labor pricing for Woodinville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Woodinville typically costs between $750 and $1,700 for a standard tank unit, and $1,700 to $4,200 or more for a tankless system. Prices vary based on unit type, labor, and necessary upgrades like a new gas line ($275–$950). Woodinville's homes average 32 years old, so older plumbing or electrical may increase labor time. Washington requires permits, seismic strapping, and an expansion tank on closed systems, which adds to the cost. Given the cool marine climate and cold winter inlet water, heat pump water heaters are a strong fit and qualify for the federal 25C tax credit (30%, up to $2,000). Many homes use electric water heating, making heat pump models a recommended upgrade for efficiency.

Given Washington’s cool marine / temperate climate and electric water heating, heat-pump (hybrid) is the sensible default for most Woodinville 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.
