Electric Water Heater Installation & Repair in Tacoma, WA

Tacoma has one of the most significant electric rate advantages in the United States. Tacoma Public Utilities (Tacoma Power) charges approximately $0.045–$0.048 per kWh — roughly 75% below the national average — because the city-owned utility runs primarily on clean Columbia River hydroelectric power. For homeowners on Tacoma Power, electric water heaters are cost-competitive with gas and often the smarter choice.

Who Is on Tacoma Power vs. PSE Electric?

Tacoma Power serves the City of Tacoma, Lakewood, University Place, and Fircrest. If your address is in these areas, your electric rate is approximately $0.045/kWh — making electric water heating roughly $20–$30/month to operate.

Puget Sound Energy (PSE) serves the outer Pierce County areas: Puyallup, Gig Harbor, Federal Way, Bonney Lake, Spanaway, Parkland, Graham, and surrounding communities. After PSE’s ~12% rate increase in January 2026, PSE electric customers pay approximately $0.13–$0.15/kWh. At that rate, a gas water heater is typically cheaper to operate if gas service is available. See our gas water heater page for gas rate details.

2026 Tacoma Power Rates

Tacoma Power rates increased 6.5% effective April 2025 (~$7/month average) and another 6.5% in April 2026. Despite these increases, Tacoma Power remains among the cheapest utilities in the country. The average residential bill for all household electricity use runs approximately $105–$115/month. Water heating accounts for 15–20% of that — approximately $20–$30/month for a 50-gallon electric tank.

University Place customers pay slightly more due to a 6% city utility tax applied on top of base Tacoma Power rates.

Electric Water Heater Options

A standard 50-gallon electric tank water heater costs around $2,500 installed and lasts 10–15 years — slightly longer than gas because there is no combustion-related wear. Electric units require no venting and no gas line, making installation simpler and placement more flexible.

A heat pump (hybrid) water heater extracts heat from surrounding air and transfers it to the water — roughly 2–3x more efficient than a standard electric tank. Heat pump units cost $3,500–$7,000 installed and qualify for a $2,000 federal tax credit through 2032. For Tacoma Power customers, the operating cost drops to approximately $12–$20/month — the most cost-effective water heating option available anywhere in Pierce County. Heat pump units need at least 700–1,000 cubic feet of surrounding air space, so they work best in basements, garages, and utility rooms.

Electric tankless water heaters provide endless on-demand hot water but require 150–200 amp electrical service. Many older Tacoma homes have 100–150 amp panels, which may require an upgrade ($1,500–$3,000) before tankless electric is feasible.

Switching from Gas to Electric

Converting from a gas water heater to electric requires capping the gas line, installing a dedicated 240V/30A electrical circuit ($200–$500 for an electrician), and possibly upgrading your panel. Total conversion cost typically adds $300–$800 to the project. For Tacoma Power customers looking to simplify — no venting, no CO risk, no gas bills — the switch often makes practical and financial sense.

Common Electric Water Heater Repairs

The most frequent electric water heater repairs are heating element replacement (upper or lower element, $150–$350) and thermostat replacement ($150–$300). Anode rod replacement ($150–$250) is a maintenance item that extends tank lifespan significantly. Unlike gas units, electric water heaters have no pilot light, no combustion parts, and no venting to maintain — fewer points of failure overall.
