A tankless water heater can provide reliable hot water without storing gallons of water in a tank. When properly sized and maintained, these systems can be a great fit for many Marin and Sonoma County homes.

At John Owens Services, we install, repair, flush, and replace tankless water heaters. Our team evaluates your home’s hot water demand, fuel source, and existing plumbing before recommending a solution. That means no guessing and no one-size-fits-all recommendations.

Many homeowners call us when an older tank water heater fails, while others are upgrading during a remodel. If you’re comparing options, explore our Water Heater services page to understand the differences between traditional and tankless systems.

Tankless units also need regular maintenance, especially in areas with mineral-rich water. If you are seeing performance issues, we can inspect the system, clean scale buildup, and help restore reliable operation before recommending replacement.

Frequently Asked Questions

Is a tankless water heater worth it?

For many homeowners, yes. Tankless systems can provide continuous hot water and take up less space than a traditional tank. The best choice depends on your home’s hot water needs and existing plumbing and fuel setup.

How long does a tankless water heater last?

A well-maintained tankless water heater can last many years. Regular flushing and maintenance are especially important in areas with hard or mineral-rich water.

Why does my tankless water heater lose hot water during winter?

Cold incoming water temperatures can increase the workload on the system. An undersized unit, mineral buildup, or maintenance issues can also affect performance.

Do tankless water heaters require maintenance?

Yes. Tankless units should be inspected and flushed on a regular schedule to help reduce scale buildup and maintain efficiency.

Can you repair my existing tankless water heater?

In many cases, yes. Our technicians can diagnose performance problems, error codes, flow issues, and maintenance-related concerns to determine whether repair is a practical option.

Can you replace a traditional tank water heater with a tankless model?

Yes. We can evaluate your home’s plumbing, gas or electrical capacity, venting requirements, and hot water usage to determine whether a tankless upgrade makes sense.
