Frequently Asked Questions

How much does water heater installation cost in Bellevue?

Tank water heaters cost $2,500 installed. Tankless installation runs $5,000–$7,000. Heat pump units cost $3,500–$7,000 but qualify for up to $2,000 in federal tax credits.

What type of water heater should I install?

It depends on your household. A 50-gallon gas tank is the most popular choice for Bellevue homes with 3–4 people. Tankless is best for high-demand households or long-term savings. Heat pump is best for max efficiency.

How long does water heater installation take?

A new tank installation takes 2–4 hours. Tankless takes 4–8 hours. If you're switching fuel types or running new gas/electrical lines, it may take a full day.

Do I need to upgrade my electrical panel for a new water heater?

Only if you're installing a tankless electric unit (which requires 120–160 amps) or a heat pump model. Standard electric tank heaters use a 30-amp circuit that most homes already have.

Can I install a water heater in my attic or closet?

Yes, with proper code compliance. Indoor installations require a drain pan piped to a drain, proper venting for gas units, and adequate clearance. Attic installations may add to labor cost due to access difficulty.

What permits are required for water heater installation in Bellevue?

A plumbing permit ($100–$175) is required by the City of Bellevue. Your plumber handles the application, pays the fee, and schedules the required inspection after installation.

Is a tankless water heater worth the extra cost?

Over 20 years, tankless typically costs less than tank because you buy one unit instead of two. You also save 24–34% on monthly energy costs. The break-even point is usually 7–10 years. See our tankless page for a full comparison.

What's included in a water heater installation quote?

A proper quote should include the unit, labor, permit fees, old unit disposal, earthquake straps, expansion tank, and drain pan. Ask your plumber to itemize — avoid quotes that bundle everything into one number.
