Repairing All Makes and Models of Tankless Water Heaters

Tankless water heaters are a great way to provide nearly unlimited hot water for your home and though they are highly reliable and last longer than conventional storage tank models, they are not completely trouble-free. Problems like mineral accumulations, combustion problems, heating element failures, or supply problems do happen, and will often need the help of a professional to solve.


With more than 80 years of service in the Lancaster and New Holland, PA area, you can count on our team at The Witmer Company for help with all your tankless water heater and plumbing needs. Our licensed, professional plumbers can provide fast, cost-effective tankless water heater repairs, as well as 24/7 emergency service when the problem simply cannot wait.

Common Problems With Tankless Water Heaters

Although most tankless water heater problems can be avoided with diligent maintenance, not all can. Some of the most common tankless water heater problems we encounter include:


  • Mineral accumulations – Minerals like calcium and magnesium, which are commonly found in hard water, can accumulate on the interior of pipes and heat exchangers in tankless water heaters, limiting water flow or blocking it completely. Normally, this can be prevented with regular flushing and proper water treatment, but it can still occur.
  • Corrosion – With the combination of heat and moisture, corrosion can often occur in the heat exchanger or other components of the water heater, especially if the water is abnormally acidic.
  • Combustion problems – A dirty burner, faulty thermocouple, or venting problems may cause the burners to shut down in gas or propane water heaters.
  • Heating element failures – On electric models, heating elements can fail after several years of use, requiring a replacement.
  • Insufficient hot water – If your tankless water heater has mineral accumulations, corrosion, or other problems, it may fail to provide enough hot water. Another cause may be a water heater that is undersized, requiring an upgrade or the addition of a secondary heater.
  • Temperature problems – A thermostat or control circuit failure may cause the water to be too hot or too cold for comfort. Other causes may include plumbing problems or improper installation.


If you are experiencing any of these problems, contact our experts at The Witmer Company. We will diagnose your water heater and offer the best solution to needs, whether that is repairs, a replacement, or an upgrade.

"Fast, fast, FAST! They came within two weeks in the busier season as our unit died right as it was starting to get hot outside. They didn’t make us feel bad for not checking the unit back in January, and it was an attic unit too! Very professional and clean, I would hire them again in a heartbeat!"
