More and more residential homes are starting to utilize tankless hot water heaters due to their convenience as well as their potential for money savings. However, like all other household appliances, tankless water heaters can break down. For that reason, it is imperative that you be familiar with the signs of issues. If you can stay ahead of problems, you can reduce the damage and get your water heater back up and running quicker. Here are three signs that your tankless water heater may need repairs.

Lack of Hot Water

By far, the most obvious sign of a problem with your tankless water heater is when there is a lack of hot water. There are many reasons why your water heater may not be producing hot water, and it is possible to perform some troubleshooting to get down to the root of the problem. First, you will want to check the settings. It may be that you just accidentally switched the settings to a cold temperature. If you are using an electric or gas system, check the utility lines to ensure they're working. If you locate loose wires or leaks, get in touch with the proper utility service immediately. In some cases, the problem could be with the heating array, in which case you will need to contact your plumber for repairs.

Inconsistent Heating

If you notice that your water is fluctuating between temperatures, there is a good chance that there is an electrical issue somewhere. If the delivery or power source is varying, then it will not function at full power. It is extremely dangerous to mess with electricity, so it is recommended to use the hot water as little as possible and get in touch with a plumber immediately to take a look.

Weird Noises

If you hear a banging, bubbling, gurgling, or hissing from or near your tankless water heater, then this is an indication that something is wrong somewhere. Your first step should be to turn the water heater off completely. There may be broken parts or debris somewhere inside the tank that could cause further damage if it continues to run. If you don't see any visible connection issues, a plumbing company should be contacted to come out and perform an inspection to diagnosis the problem

If you recognize any of the aforementioned signs with your tankless water heater, a residential plumbing company should be contacted as soon as possible to schedule an appointment for an inspection, diagnosis, and repair.
