Tankless Water Heater Repair 101: Things You Should Watch For

Tankless hot water heaters have become a popular investment among those who are looking for more efficient hot water supplies as well as those with heavy demand for hot water in their homes. If you've installed a tankless hot water heater in your home, it's important for you to understand when it is in need of repairs. Here's a look at some of the things you need to know about tankless water heaters and the repairs that they often need.

Noise From Your Tankless Water Heater

If you notice that your tankless water heater has started making banging, knocking, or clanging noises when it engages, that's a key sign that there's something malfunctioning inside the system. In some cases, these sounds are caused by mineral accumulations inside the heater from hard water. Screeching and other noises may indicate problems with the pump or the bearings, so it's important to get unusual sounds addressed right away.

Water Temperature Is Moderate But Not Hot

If you're accustomed to your tankless water heater producing good hot water and suddenly notice that the water coming from the tank is moderately warm but not sufficiently hot, that's a sign that there's either a problem with the tank's thermostat or the heating element. You'll need to have both tested and have the problematic component replaced.

Lack Of Hot Water

If you turn on your hot water and the water doesn't get hot, that's a key indication that your tankless water heater is malfunctioning. Have someone stand by the water heater when you turn the hot water on to see if the heater is engaging at all. If it is, the problem could rest in the thermostat or the heating unit. If the heater doesn't turn on, that's a sign that the unit is in need of repair as it may have a blown fuse. 

Leaks Around The Water Heater

Your tankless hot water heater is a sealed, enclosed unit. There shouldn't be any signs of leaks around the water heater enclosure. If you see water on the floor near your tankless water heater, or you can see water on the heater case, you'll need to have the water heater examined by a repair technician. It's important for you to address leaks right away because they can lead to water damage and costly issues. You may have a blown seal, a bad connection, or other similar problem.

Understanding the basics of water heater issues can help you to identify problems before they become complete component failures. Contact a tankless water heater repair technician for more information.
