Whether you're a homeowner or a business owner, having a reliable and efficient water heating system is crucial. We understand the importance of a well-functioning tankless water heater, and in this article, we will answer all your questions regarding coil replacement. Let's dive in!

The Importance of Tankless Water Heater Coil Replacement

A tankless water heater relies on a coil to heat the water as it flows through the unit. Over time, due to factors like mineral buildup, wear and tear, or improper maintenance, these coils may become inefficient or malfunction altogether. This can result in reduced hot water output, fluctuating water temperatures, or even complete failure of the unit. By replacing the damaged or worn-out coils, you can restore the performance and efficiency of your tankless water heater.

Signs That Your Tankless Water Heater Coils Need Replacement

Identifying when your tankless water heater coils need replacement is essential to avoid sudden breakdowns or inconvenience. Look out for the following signs that might indicate it's time to replace your coils:

  • Decreased hot water supply
  • Inconsistent water temperature
  • No hot water production
  • Loud or unusual noises coming from the unit
  • Leakage or water pooling around the unit

If you notice any of these signs, it is highly recommended to contact a professional plumber who specializes in tankless water heater coil replacement.
