When temperatures drop around Puget Sound, your water heater works overtime. Long showers, extra laundry, and heavier hot-water demand can push aging systems to their limit. Whether you own a traditional tank model or an energy-efficient tankless unit, keeping it in top shape is key to comfort, safety, and lower utility bills.
At Bob Oates Plumbing, Sewer & Rooter, our licensed technicians have been repairing and replacing water heaters across the Greater Seattle Area for more than 30 years. Here’s what every homeowner should know about staying warm and prepared this winter.
Tank vs. Tankless Water Heaters: What’s Right for Your Home?
Most homes in Seattle use either a storage tank water heater or a tankless (on-demand) water heater — and both have clear advantages.
Tank Water Heaters
• Store and heat a large volume of water for immediate use.
• Typically lower upfront cost and easier installation.
• Require more space and use more energy to keep water hot 24/7.

Tankless Water Heaters
• Heat water only as it’s needed, saving energy and space.
• Provide continuous hot water — perfect for households with multiple showers running at once.
• Higher upfront cost but often lower long-term energy bills.

Signs It’s Time to Repair or Replace Your Water Heater
If you’ve noticed inconsistent water temperature or unusual noises, your water heater could be signaling trouble. Watch for these red flags:
• Rust or corrosion around the tank or in your water.
• Popping or rumbling sounds, often caused by sediment buildup.
• Metallic taste or odor in hot water.
• Hot water running out quickly or turning cold unexpectedly.
• Water heater older than 12 years — nearing the end of its efficient lifespan.
When caught early, many issues can be repaired affordably. If replacement makes more sense, we’ll recommend the right system for your home and budget.

FAQs about Water Heaters
1. How long does a water heater last?
Most traditional tank water heaters last about 10–12 years, while tankless systems can operate efficiently for up to 20 years with proper maintenance. Regular flushing, filter cleaning, and annual inspections can help maximize lifespan and performance.
2. What’s the difference between tank and tankless water heaters?
A tank water heater stores and heats a large volume of water for immediate use, while a tankless water heater heats water only as it’s needed. Tank models cost less upfront, but tankless systems save more energy and take up less space over time.
3. Should I repair or replace my water heater?
If your unit is under 10 years old and showing minor issues—like inconsistent temperature or mild sediment buildup—repairs may be sufficient. But if it’s leaking, corroded, or nearing the end of its lifespan, replacement is often the smarter long-term investment.
4. Is a tankless water heater worth it in Seattle?
Yes — for many homeowners. Seattle’s energy costs and compact home layouts make tankless water heaters a popular, efficient choice. They deliver continuous hot water, use less energy, and can qualify for local utility rebates. Our team can help you determine whether a tankless upgrade makes sense for your household.
