FAQ
Frequently asked questions
Rough guide for tank heaters: 30–40 gal for 1–2 people, 40–50 gal for 3–4 people, 50–80 gal for 5+ or homes with soaker tubs. For tankless, sizing is based on GPM (gallons per minute) and incoming water temperature — Washington's cold winter groundwater requires a larger tankless unit than the same household in California.
Often yes. Heat-pump (hybrid) water heaters use 60–70% less energy than electric tanks. Washington offers state rebates ($500–$1,000 depending on utility) and the federal IRA tax credit covers 30% of installed cost up to $2,000. Payback in WA is typically 4–7 years. Best for homes with a heated garage or utility room.
Yes. Washington L&I requires a plumbing permit for water heater replacement in most jurisdictions (Seattle, King County, Pierce County, Spokane County, etc.). Our partner plumbers pull the permit and handle the inspection. Skipping the permit can void your homeowner's insurance and cause issues at resale.
Tank: about 60–90 minutes after install completes (time for the new tank to heat). Tankless: hot water on demand the moment install completes. Heat-pump: 3–4 hours to first hot water as the compressor cycles.
Ballpark all-in (unit + labor + permit + haul-away): 40-gal electric tank $1,400–$1,900. 50-gal gas tank $1,800–$2,500. Tankless gas $3,500–$6,500. Heat-pump 50-gal $3,000–$5,500 before rebates. Your installer will quote firm pricing before any work begins.
