What it costs across Washington
Water Heater Replacement
Water heater replacement cost depends on the unit type, size, fuel source, and what code upgrades the job triggers. A basic 40-gallon gas tank swap and a high-efficiency tankless install can sit nearly $4,000 apart.
Water Heater Installation
Water heater installation cost covers the labor and parts to fit a new unit — whether it's a first-time install, a fuel switch, or a tankless conversion. The number swings with venting, gas-line work, and whether the location changes.
Water Heater Repair
Water heater repair cost depends on the failing part and whether the unit is gas or electric. Most common repairs — thermostats, elements, thermocouples, valves — land between $150 and $800 including labor.

What’s different about Washington.
Generic cost pages skip the things that actually decide your price and your unit’s lifespan here — local code, water, and the money you can claim back.
Recommended unit for Washington
Given Washington’s cool marine / temperate climate and electric water heating, heat-pump (hybrid) is the sensible default for most Washington 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.
