What affects your water heater price
Tank vs. tankless vs. heat-pump
Tankless and heat-pump units cost more up front but last longer and cut energy bills. A like-for-like tank swap is the most affordable option.
Fuel type
Gas, electric, and heat-pump units have different equipment, venting, and electrical requirements that change the total.
Code upgrades
Washington code may require an expansion tank, new venting, a gas-line adjustment, a drain pan, or an electrical circuit — especially when changing fuel or type.
Location & access
A tight crawlspace, attic, or upstairs closet takes longer than a garage install and can affect labor.
Permits & haul-away
A permit, inspection, and disposal of your old unit are part of a proper installed price.

Frequently asked questions
Tank vs. tankless — which is cheaper?
A standard tank is cheaper to install ($3,000–$4,500). Tankless costs more up front ($6,500–$10,000) but lasts roughly twice as long, never runs out of hot water, and lowers energy bills — so it can cost less over its lifetime.
What should I do if my water heater is leaking?
If safe to do so, turn off the water supply to the unit and contact Eco to get our expert plumbers out immediately. Even a small leak can quickly become a larger problem and cause significant water damage.
How long does a water heater last?
A standard tank lasts about 8–10 years, tankless units 15–20 years, and heat-pump models 10–12 years. If yours is near the end of its range, planning ahead avoids an emergency failure and water damage.
Are heat-pump water heaters rebate-eligible in Washington?
Frequently, yes. High-efficiency heat-pump (hybrid) water heaters qualify for utility rebates in Washington — PSE pays $1,000–$1,100 on qualifying Tier 3/4 models, Seattle City Light $750, and Snohomish PUD up to $1,000 — and income-eligible households can add up to $1,750 through WA HEAR. The federal 25C tax credit expired December 31, 2025, so 2026 savings come from these state and utility programs. Eco helps you find and apply eligible rebates; figures verified as of July 2026.
