 5 Great Reasons to Invest in Maintenance from Absolute Plumbing for Your Tankless Water Heater

  • Prolonged lifespan
    Regular maintenance helps to keep your tankless water heater in optimal condition, which can extend its lifespan. By ensuring that all components are clean and functioning properly, you can avoid costly repairs or the need for premature replacement.
  • Improved energy efficiency
    Over time, mineral deposits can build up in the heat exchanger of your tankless water heater, reducing its efficiency. Regular maintenance includes flushing out these deposits, allowing the unit to operate at peak performance and save energy. This can result in lower utility bills and a more environmentally-friendly home.
  • Enhanced performance
    Neglecting maintenance can lead to reduced water flow or inconsistent water temperature from your tankless water heater. By regularly cleaning and inspecting the unit, you can prevent these issues and enjoy a steady supply of hot water whenever you need it.
  • Cost savings
    Investing in maintenance for your tankless water heater can actually save you money in the long run. By addressing any minor issues early on, you can prevent them from turning into major problems that require expensive repairs or replacement. Additionally, an efficiently operating tankless water heater will consume less energy, resulting in lower utility bills.
  • Peace of mind
    Regular maintenance provides peace of mind knowing that your tankless water heater is in good working order. You won't have to worry about unexpected breakdowns or interruptions in hot water supply. Instead, you can enjoy the convenience and comfort of a reliable water heating system.

What Our Customers Are Saying


“It's the busiest season on the Outer Banks, but Absolute Plumbing installed a new water heater in record time. Great job! Have used Absolute Plumbing for years, and highly recommend them.”
—Robin H.


“Kevin did a great job and was very informative and kind. All the work got done professionally and timely. Absolute had done some work for me years ago when I first bought my home and they will always be my “go to” plumber from now on. Great job, very happy with their work.”
—Maria F.


“We are a small property management and maintenance company here and we can’t always handle some bigger problems, put a call into absolute after hours today and they sent someone out right away to take care of a blocked sewer pipe, I will definitely use them again in the future and recommend them to all of my homeowners.”
—Rob S.

—David S.
