What Are Tankless Water Heaters?

Unlike traditional water heaters, tankless models heat water directly as it flows through the unit. This “on-demand” system means you’ll never run out of hot water, even during peak usage. Plus, tankless heaters save space, reduce energy costs, and offer a longer lifespan than conventional tanks.

    True professionals and genuinely care about the relationship with their customers! Hurricane Helene damaged our tankless hot water heater. Once power was restored but no hot water, I called Ken's Plumbing at 8:30am and by 4:00pm we had hot water and a new heater. James, Ben, Peter, and Keith are rock stars! Greatly appreciate all at Ken's Plumbing. They are the best!

    Just had my old and failed water heater replaced with a tankless unit by Noah and Keith and they were fantastic. Not only was the job done right and looked good, but this was the only plumbing company of 3 quotes that I got for the job that took into account the existing natural gas load on the other household appliances. I'm thoroughly impressed with the job done today, thanks guys.

    I’ll be sure to give Keith and Lorenzo another call, the next time I need our tankless water heater treated. My family appreciates the care and concern taken by these individuals. Excellent job!

  • Jim D.
    Ken's Plumbing just replaced two tank water heaters with a tankless system in our home, and we couldn't be more pleased. The folks in the office were courteous and responsive, and Keith worked efficiently and respectfully while at our home. Everyone did what they said they'd do. In my comparative shopping, their pricing was very fair and competitive. Excellent customer service is tough to find these days, but Ken's still provides it. Ken's magnet is now the only plumbers magnet on our refrigerator.

Tankless Water Heaters FAQs

Is it worth putting in a tankless water heater?

According to the US Department of Energy, for homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. This is because they only heat water when it’s needed, eliminating standby energy loss. Tankless water heaters also have a longer lifespan compared to tank-style models. Read more about the pros and cons of tankless water heaters.

What is the life expectancy of a tankless water heater?

According to the US Department of Energy, most tankless water heaters have more than 20 years of life expectancy. They also have easily replaceable parts that may extend their life by many more years. In contrast, storage water heaters last 10–15 years.

How do I tell if a tankless water heater is going bad?

Watch for these signs:

  • Inconsistent or fluctuating water temperature
  • It takes longer than usual to get hot water
  • Low water pressure
  • Leaks around the unit
  • Error messages or codes on the display
Can you run out of hot water with a tankless water heater?

Technically, no. Tankless systems provide hot water on demand. However, if multiple fixtures are used at once or the unit is undersized for your home’s needs, the flow rate may drop, and water may not stay consistently hot.

How do you fix a tankless water heater problem?

Follow these steps to troubleshoot and fix common tankless water heater issues:

  1. Check for error codes: Most tankless units display a code when something’s wrong. Refer to your owner’s manual to identify the issue.
  2. Inspect the power or gas supply: Make sure the unit is plugged in, the circuit breaker hasn’t tripped, and the gas valve is open if it’s a gas model.
  3. Clean the air and water filters: Clogged filters can restrict flow and cause heating problems. Remove and rinse them according to the manufacturer’s instructions.
  4. Flush the system to remove scale buildup: Mineral deposits can affect heating efficiency. Flushing the unit with a descaling solution once a year helps maintain performance.
  5. Reset the unit: After performing maintenance, use the reset function (if available) to clear minor faults.
  6. Call a licensed plumber for persistent issues: If the unit still won’t produce hot water or shows repeated errors, contact a professional to inspect electrical components, sensors, or internal parts safely.
How much does it cost to service a tankless water heater?

The cost to service a tankless water heater averages around $600, but prices can range from $75 to $1,300, depending on the repair type, part replacement, and unit condition.
