It's Electric! How to Easily Troubleshoot Electric Tankless Water Heater Problems

by Eccotemp Systems

When it comes to choosing a tankless water heater for your home, you have many styles and brands to choose from. Electric tankless models offer many benefits that gas tankless, or classic tank models cannot. Electric tankless water heaters can be installed virtually anywhere in your house that have the appropriate hookups (this is great if you have limited space in your home.) Some common places that our customers have installed their electric water heater are offices and bathrooms. They also offer cheaper installation costs because no venting is required. In most gas models additional venting parts and accessories must be purchased. Electric models are also safer for the environment because they do not vent out gasses into the environment.

Pros of an Electric Tankless Water Heater

  • Simple Installation – no venting required.
  • Can be installed in most areas of the home.
  • Variety of Sizes
  • When considering what size electric tankless water heater, consider the following factors: the temperature of the incoming ground water temperature, the flow rate required, and any breaker panel restrictions.

    At Eccotemp, there are three sizes of electric tankless water heaters to choose from: 11, 18, or 27 Kilowatt. The iE Series features a sleek, modern design and uses 60% less electricity than regular tank water heaters.

    However, like any product, there are likely to be problems or issues that arise after installation. Many of these problems can be easily solved at home without calling a professional, even if you have limited knowledge about water heaters. Continue reading to learn about common electric tankless water heater problems that you can easily fix yourself! * Be sure you have adequate amperage that is required for the model you’ve chosen.

    The first, and most important, step to any issue that you may be troubleshooting with your electric tankless water heater is to turn off the power. This is for safety purposes and can easily be done by turning off the fuse or the circuit breaker that the water heater is connected to.

    Noises Coming from Your Water Heater

    If you hear a rumbling noise coming from your electric tankless water heater this most likely indicates boiling water. This is a result of your water heater overheating because of sediment build-up.

    If you hear a high pitching noise that can be described almost as whining, this can also be a result of sediment build up. When this high-pitched noise is heard that is the result of scale build-up on the heating elements.

    To resolve both noise issues, all you must do is descale and flush out your tankless water heater. This needs to be done every six months to ensure that your tankless water heater is running as efficiently as possible. This sounds difficult but with the Eccotemp EZ Flush Descaler Kit, simply connect your tankless water heater to the descaler kit and flip the switch. Once the water heater has been flushed out, the EZ Flush can be stored until it is needed for the next cleaning in six months.

    Restricted Energy Supply

    Another common problem that has an easy solution is if your water heater will not turn on because the energy supply is cut off. Your energy supply could have been cut off for a variety of reasons:

    • Your circuit breaker has tripped.
    • Your electrical system has a short circuit.
    • The ignition system, such as the electrode, has malfunctioned.
