Signs That Indicate Your Tankless Water Heater Is In Need Of Repair

Posted on: 8 February 2021

When building homes or replacing old water heaters, many people are opting to install tankless water heaters. Tankless hot water heaters have become increasingly popular due to the fact that they are very energy-efficient, can produce unlimited hot water on demand, and last longer than traditional tank water heaters. However, just like any other appliance in a home, a tankless water heater can develop problems. The good news is that many tankless water heater issues can be repaired by an experienced plumber. Some of the common signs that your home's tankless water heater needs professional repair include the following.

Poor Water Pressure When Using Hot Water

If you have poor water pressure when you turn on the hot water but don't notice the same problem when you turn on the cold water, the issue is probably being caused by your tankless water heater. A lot of areas have hard water, which means that the mineral content in the water is very high. Over time, minerals can build up inside the tankless water heater if hard water is present. When this happens, water flow is restricted and you will notice that water pressure is reduced. A plumber will be able to remove the mineral build-up inside the water heater to solve the problem.

Lack of Hot Water

When you have a tankless water heater, it is normal to expect hot water at all times. Thus, it can be quite alarming if you turn on the shower and discover that your water is only lukewarm. In this type of situation, a lack of hot water may be due to a faulty heating element or an issue with the water heater being powered. If you have an electric tankless water heater, the wiring may be loose, and if you have a gas tankless water heater, you may have an issue with your gas line. 

Water Heater Shuts Off

Tankless water heaters are equipped with safety features to help prevent major damage from occurring. One of these safety features is automatically turning off if exhaust gases build up. When a tankless water heater is installed, venting tubes are attached to allow to exhaust gases to be removed. But it is possible for the venting tubes to become clogged. If the venting tubes become blocked and the exhaust gases can be released, the tankless water heater will not operate. A plumber has the necessary skills to clean the venting tubes so the water heater can operate properly.
