Water heater replacement in Tigard and Beaverton typically costs between $1,800 and $4,500 for a complete installation, with most homeowners paying around $2,400 for a standard 40-50 gallon gas unit. The final price depends on the heater type (tank vs. tankless), fuel source (gas vs. electric), capacity, and whether code upgrades are needed for your home.
What We're Seeing: Current Replacement Costs in Washington County
After completing hundreds of water heater installations across Tigard, Beaverton, and surrounding areas, we've found that pricing breaks down consistently based on a few key factors. Here's what local homeowners are actually paying in 2024:
Standard tank water heaters: A 40-gallon gas water heater replacement runs $1,800-$2,600, while a 50-gallon unit costs $2,200-$3,200. Electric tanks are typically $200-$400 less since they don't require venting work. These prices include hauling away your old unit, basic code compliance updates, and permit fees required by Beaverton and Tigard.
Tankless water heaters: We're installing tankless units in the $3,200-$5,500 range depending on whether it's gas or electric. Gas tankless installations cost more because they require upgraded venting (often stainless steel through-the-wall venting) and many older homes in neighborhoods like Garden Home and Oak Hills need gas line sizing upgrades to supply adequate BTUs.
Heat pump water heaters: These energy-efficient electric units cost $2,800-$4,200 installed. We've seen increased interest from homeowners in Lake Oswego and West Linn pursuing the Energy Trust of Oregon rebates, which can offset $600-$850 of the installation cost.
Why Costs Vary Between Homes
In our experience servicing homes built everywhere from the 1950s ranch-styles in Tigard to newer construction in South Beaverton, several factors significantly impact the final price. Older homes frequently need expansion tank installations ($180-$250) if they're on municipal water with a pressure-reducing valveβrequired by current Oregon code but often missing from installations done 15+ years ago.
We also encounter earthquake strapping requirements that weren't enforced when many water heaters were originally installed. Both Beaverton and Tigard building departments now require seismic straps, adding $75-$150 to installations when hardware isn't already in place.
Access matters considerably. Water heaters tucked into tight crawl spaces, attics, or garages with narrow doorways take longer to remove and install, which can add $200-$400 in labor. We've worked on homes in older Tigard neighborhoods where getting a new heater into the basement required creative maneuvering that simply takes more time.
Tank Size and Capacity Considerations
We help Beaverton and Tigard homeowners select appropriate capacity based on household size and usage patterns. A couple in a smaller home does fine with a 40-gallon tank ($1,800-$2,400), while families with teenagers or homes with soaking tubs benefit from 50-gallon units ($2,200-$3,000) or even 75-gallon tanks ($2,800-$3,600).
Many clients ask whether to upsize when replacing. If you've experienced running out of hot water, upgrading makes senseβbut it's worth knowing that a larger tank means slightly higher ongoing energy costs. For homes where multiple showers run simultaneously in the morning, we often recommend either a larger tank or exploring tankless water heater options that provide continuous hot water.
Gas vs. Electric: Installation Price Differences
Gas water heaters dominate in Tigard and Beaverton because natural gas is widely available and cheaper to operate than electric resistance heating. Gas installations cost $200-$500 more than comparable electric tanks due to venting requirementsβwe're running either Type B vent through the roof or installing power-vented systems with PVC through exterior walls.
Electric water heaters are simpler to install since they only need proper circuit breakers and wiring (typically 30-amp, 240-volt), with no combustion air or venting concerns. However, ongoing operating costs run roughly double what you'd pay with natural gas in our area, which is why we've serviced very few straight electric resistance tank replacements recently.
Code Compliance and Permit Costs
Every water heater replacement in Beaverton and Tigard requires a plumbing permit and inspection. Permit fees run $80-$150 depending on the city and whether it's a like-for-like replacement or a fuel-type conversion. As licensed contractors (CCB #254405), we pull permits for every installationβit protects homeowners and ensures work meets Oregon plumbing code.
Inspectors verify proper temperature and pressure relief valve piping, adequate combustion air for gas units, proper venting, correct electrical connections, seismic strapping, and drain pan installation where required. These aren't optional items, and we build code compliance into every quote we provide.
