Top Signs That Your Tankless Water Heater Needs To Be Repaired

Posted on

If you live in a smaller home or apartment, a tankless water heater can be a true godsend. Because there is no bulky tank to take up a lot of space, you're able to conceal the tankless unit in a compact place such as under the sink or in an obscure area of the garage. Tankless water heaters traditionally heat the water up on demand instead of keeping a reserve on deck, so unless you notice that there is absolutely no hot water, it's possible to be completely in the dark about the true status of your unit. If any of the signs listed below start to become a reality in your home, you may need to contact a heating, ventilation and air conditioning (HVAC) contractor to have your water heater repaired.

Strange Sounds Occur When You Turn On The Hot Water

It's important for you to pay attention to the sounds that you hear each time you turn on the hot water. Under normal circumstances, your tankless water heater should operate quietly with barely any audible noises for you to hear. However, when you switch on the hot water valve and hear unsettling clangs, bangs, or knocks, it's time to take notice.

When your tankless water heater is starting to go under, it might require more power to get the water up to the desired temperature. There is no residual water to funnel through the pipes because there is no tank to hold it in. The water must be heated up at the point of contact, and if there are one or more faulty parts in your water heater, this could require so much power that the device emits loud sounds that are almost impossible to ignore.

The Water Temperature Fluctuates Wildly

You should also check for differences in the water temperature throughout your home. Does the water run extra hot in one bathroom but tends to be much colder when you're trying to run warm water to wash dishes? These are the kinds of changes that can indicate a small water heater problem that needs to be caught before the situation gets too far out of control.

Having your tankless water heater repaired helps to bring balance back to the stream of water that flows through your house. If you observe these telling symptoms get on the line with an HVAC contractor and schedule a time for them to come out for an inspection. Look for someone near you who provides tankless water heater repair to learn more.
