Tankless water heaters are becoming more and more popular among modern homeowners. The sleek design of a tankless system allows homeowners to save space and energy without sacrificing access to hot water.
As beneficial as a tankless water heater can be, these types of appliances are not without their faults. You need to be mindful of some potential problems that might plague your tankless water heater so that you will be prepared to invest in immediate repairs.
1. Burner Problems
A tankless water heater that is powered by natural gas will have a burner that contributes to the creation of hot water. If you notice that your water supply isn't as hot as it used to be, then a damaged burner may be the problem. More specifically, the problem is likely coming from the thermocouple — a small component within the burner.
The thermocouple is designed to detect the presence of the pilot light in a natural gas tankless water heater. A faulty thermocouple won't register that the pilot light is on, and the burner will not be engaged. The result is a tepid water supply.
Your plumber can easily fix the problem by replacing the thermocouple.
2. Heating Element Problems
A problem with the heating element will produce many of the same symptoms as a burner problem. Electric tankless water heaters have a heating element instead of a burner that helps raise the water temperature inside your home.
The heating element is not designed to last forever, and it will eventually need to be replaced in order for your electric tankless system to function properly. A decline in water temperature is the most common symptom of a heating element problem, so contact your plumber as soon as you notice any unexplained changes in your hot water temperatures.
3. Sediment Problems
Most residential water reserves contain trace minerals. These minerals don't pose a threat to your health, but they can compromise the health of your tankless system when they are deposited along the interior walls of pipes, valves, and fixtures.
Homeowners typically think of sediment problems as being limited to a water heater with a tank. The truth is that a tankless system is susceptible to sediment damage as well.
Sediment buildup can form on the heating element, preventing the full transfer of heat from the element to your hot water supply. Over time, this sediment barrier could cause your tankless unit to overheat. An experienced professional can remove the sediment scale from your tankless water heater with ease.
