Tankless Water Heater Maintenance in Nashville, TN

Hoffmann Brothers recommends annual maintenance of your tankless water heater, starting with the year it is installed. Many manufacturers, like Navien, require annual maintenance as a part of their warranty policy. This routine servicing includes:

  • inspecting the overall operation
  • acid flushing the heat exchanger
  • checking the connections and exhaust vents
  • cleaning the flame sensor
  • flushing the water heater

How Does a Tankless Water Heater Work?

An endless hot water heater, often referred to as an on demand water heater or tankless unit, brings hot water to your shower and appliances by the following process:

  1. Water enters the heater.
  2. The water-flow sensor detects the strength of the water flow.
  3. The water heater’s computer automatically ignites the burner.
  4. Water is forced to circulate through the heat exchanger.
  5. The exchanger heats the water to the set temperature.

When you turn off the hot water tap or appliance, the tankless hot water system turns off. It’s that simple.

Is an On Demand Water Heater Worth It?

As you weigh the tankless water heater pros and cons, consider these seven factors:

  1. Cost: While the initial investment is typically higher than a standard water heater, the rest of these considerations could more than justify it over time.
  2. Service: Annual servicing is required just like any water heater system.
  3. Life Expectancy: Endless hot water systems can last 15–20+ years.
  4. Endless Hot Water: This means hot water on demand that won’t “run out.”
  5. Efficiency: A tankless hot water heater is up to 40% more efficient than a 50-gallon tank water heater and could save at least $100/year in energy consumption (fuel types can affect this significantly as well), essentially paying for themselves within 10 years.
  6. Compact & Convenient: A tankless water heater can save much-needed space with a wall mount or outdoor installation.
  7. Incentives: Utility companies often offer incentives and rebates for installing a tankless water heater system.

Common FAQs for Tankless Water Heaters


What Are The Benefits Of Having A Tankless Water Heater?

Tankless water heaters are considered on-demand water heaters and their main benefits include:

  • Greater efficiency than standard water heaters
  • Lower monthly costs to operate than standard tanks
  • Longer lifespan than standard systems
  • Less storage space than standard hot water heaters
  • No more cold showers because you’ll enjoy endless hot water


Do Tankless Water Heaters Run Out Of Hot Water?

No. Standard hot water systems depend on a tank filled incrementally with water that gets slowly heated. When it runs out, you’ll have to wait until it gets heated and filled again. Not so with tankless systems, which heats the water as it passes through the heat exchanger. You’ll never need to wait for hot water with a tankless unit.


How Long Does a Tankless Water Heater Last?

While standard hot water heater systems have a life expectancy of 7–10 years perhaps (up to 12 years or more with regular maintenance), tankless water heater systems can last 15–20 years or more.
