Two Troubleshooting Tips For Tankless Water Heaters

Posted on: 17 November 2020

Have you ever tried to take a shower and there's no hot water? Waiting for the tank to refill is not always possible if you're running late for work or have other obligations. A tankless water heater may be the solution to this problem. Water heaters that use tanks store a limited amount of hot water at a time. When that water is gone, you are left waiting. Tankless water heaters heat the water as it comes through the unit, so there is nearly an unlimited amount of hot water. There are still some inconveniences that may occur due to normal wear and tear. Learn how to troubleshoot basic tankless water heater issues by following these steps.

Element

A heating element inside the appliance is responsible for heating the water. If it fails, the water will be cold until it is replaced. These are the steps to change the element and install a new one:

  1. Make sure the power to the heater is turned off. Check your breaker box and find the appropriate switch and flip it to "Off."
  2. Place a bucket under the drain valve on the bottom of the water heater. Open the valve so the remaining water in the unit can be drained out.
  3. Use a screwdriver to remove the screws connected to the element. Place them in a safe spot so you do not lose them.
  4. Some models may require a special wrench to remove the element. Check with your model so you can purchase one ahead of time if necessary.
  5. Remove the element and discard it.
  6. Install a new element and screw it into place.
  7. Turn the power back on to the water heater.

Once the new element is in place, try running hot water to see that it is fixed.

Overloaded System

A tankless water heater can produce more hot water than tanks, but it can become overloaded if too many people or appliances are using hot water at the same time. If this happens frequently, you can try to limit the amount of users at once and see if it helps. You can also install a new water heater in some other part of the building or upgrade the tankless water heater to a large model.
