Signs That Tankless Water Heaters Need Servicing

Most tankless water heaters are designed to last for 20 years. So, if yours is having problems and was fitted before the turn of the century, a new unit may be the best solution. However, problems may occur long before your heater reaches the 20-year mark.

The decision between selecting a repair or replacement will depend on the type and severity of the issue, but the following signs all point towards problems that require some action;

  • You have noticed leaking from the unit or connected pipework
  • The tankless water heater has started to make strange noises
  • Your water supply to the shower delivers bursts of hot and cold water
  • The water delivered from your taps is cloudy or misty
  • Your energy bills have seen a noticeable increase

Unfortunately, leaving the issue untreated will continue to cause frustration and increase your costs. Furthermore, fixing the faults will help protect your family. The sooner you act, the sooner you can begin to reap the rewards of a safe, efficient, and functional tankless water heater for the home or business building. 

Diagnosing Tankless Water Heater Problems In Phoenix, AZ

Spotting the signs of problems with your tankless water heater is one thing. However, the right fix cannot be found until you have troubleshot the issues. 

While tankless water heaters are known for their reliability, ongoing troubles could be caused by damage to individual parts or contributing external factors. Our experts will conduct a full analysis to check each of the following common causes;

 Mineral build-ups caused by hard water from the local water supply,

  • Issues with your home’s gas supply line or infrastructure
  • Cross-flow problems where hot and cold water become mixed
  • Improper ventilation that impacts the heat exchange
  • Individual faulty parts including the fan, heat exchanger, or burner

Whatever the problem might be, an accurate diagnosis will help determine whether you would be better suited to a repair or replacement. Our experts will help you gain a clear understanding of the costs, timeframes, and impact on long-term efficiency. However, the final decision is always yours. 

Tankless Water Heater Repairs & Installations In Phoenix

Before repairing your tankless water heater in Phoenix or surrounding cities, it may be tempting to take the DIY route. However, calling a professional team is always the best solution.

A professional service that extends to all plumbing repairs will ensure that tankless water heaters are back to their best, or replaced with new models if required. Moreover, they will be supported by the best plumbing infrastructure. Conversely, a botched DIY effort could quickly cause worsening problems that affect other parts of the home.
