Tankless Water Heater Maintenance in New Jersey

Contact Us Today

A tankless water heater is one of the most efficient upgrades you can make in your New Jersey home — but only if it’s maintained properly. Unlike traditional tank systems, tankless units need annual cleaning, flushing, and inspection to keep their high performance, prevent mineral buildup, and maintain system lifespan.

At Doctor Water Heater, we provide professional tankless water heater maintenance across all of New Jersey, including Morris County, Essex County, Passaic County, Bergen County, Union County, Somerset County, and surrounding areas. With hard water being common throughout the state, regular maintenance is essential to keep your tankless system running smoothly year after year.

Whether you own a Rinnai, Navien, Noritz, Rheem, Bosch, or any other major brand, our licensed and certified technicians make sure your tankless water heater stays efficient, reliable, and built to last.

Why Tankless Water Heater Maintenance Is Essential in New Jersey

Tankless systems are known for their energy efficiency and long lifespan — but they require regular maintenance to stay that way. New Jersey’s hard water increases the rate of scale and mineral buildup, which directly affects performance, temperature, and unit longevity.

Here’s why annual tankless water heater maintenance is a must:

  1. Prevents Hard Water Scale Buildup: Mineral deposits from New Jersey’s water supply can coat the heat exchanger, reducing efficiency and leading to overheating.
  1. Extends the Lifespan of Your Tankless System: A properly maintained tankless heater can last 15–20 years. Without maintenance, lifespan drops significantly.
  1. Improves Performance & Water Flow: Regular flushing removes internal blockages that reduce flow rate and cause temperature inconsistencies.
  1. Reduces Energy Bills: A scale-free system heats faster and uses less energy — saving New Jersey families money month after month.
  1. Prevents Costly Breakdowns: Most tankless water heater repairs are caused by neglect. Annual service avoids expensive part failure.
  2. Required by Manufacturer Warranty: Brands like Navien, Rinnai, and Noritz require yearly flushing to keep warranty coverage active.

Signs Your Tankless Water Heater Needs Maintenance

Even before the yearly service is due, your unit may already be showing symptoms of buildup or internal wear.

Look for these common warning signs:

  • Reduced hot water flow
  • Temperature fluctuations
  • Water taking longer to heat
  • Strange noises (hissing, rumbling, clicking)
  • Error codes on the tankless display
  • Sudden system shutdowns
  • Hot water that feels “weak” in winter
  • Higher monthly gas or electric bills

If you notice any of these issues, schedule a maintenance visit with Doctor Water Heater before the problem gets worse.

How Often Should You Maintain a Tankless Water Heater in New Jersey?

Because New Jersey water is high in minerals and sediment, we recommend:

✔ Once a year for all New Jersey homes: (Required for warranty)

✔ Every 6 months if you have very hard water: (common in Morris, Essex, Union, and Passaic Counties)

✔ Every 6 months if your system supports multiple bathrooms or high-demand usage: Skipping maintenance shortens the lifespan of tankless units by 50–70% — and in many cases voids warranty protection.
