Water heater installation cost by job.
Installed-labor pricing for Bothell, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Bothell typically costs between $800 and $1,800 for a standard tank unit, and $1,800 to $4,600+ for a tankless system. Because most Bothell homes were built around 1992, many existing installations may need updates to meet current Washington codes, including seismic strapping and expansion tanks on closed systems. The local marine climate and cold winter inlet water affect unit sizing and efficiency. Washington's energy code increasingly encourages heat pump water heaters, which qualify for a federal 25C tax credit of 30% up to $2,000. Permit fees and new gas line runs ($300–$1,000) can add to the total. Choosing a heat pump model can offset higher upfront costs with long-term energy savings.
