3 Signs That Your Tankless Water Heater Is About To Fail

Blog

Tankless water heaters are an excellent option when it comes to addressing your water heating needs. This is because they only heat water when the need arises, a feature that works in your favor whenever you are not home. The same cannot be said about their tank-based counterparts that waste energy by continually reheating water stored in the tank even when you are not around.

Despite the benefits that tankless water heaters have to offer, they are not immune to wear and tear, and it's prudent to know when they are in bad shape. Remember that repairs should only be carried out by a professional. That said, here are the signs that your tankless water heater needs repair.

1. Failure to Produce Hot Water

As the name suggests, a water heater is supposed to produce hot water. Failure to do so means that the heating element most likely has a problem. There might also be an issue with the power source, whether the system runs on electricity or gas. Calling in a professional tankless water heater service is the best thing to do when having such a problem.

2. Water Leaks

Water leaks are not that hard to detect because you need to check if you find water puddles around. From faulty pipe connections to improper venting and sediment buildup, several issues can result in water leaks. Never overlook leaking problems, as they can lead to serious issues such as rust, structural damage, and mold growth.

3. Weird Noises

Your heater is bound to produce a sound as it heats the water. However, a change in this sound suggests that your tankless water heater has an underlying problem. Hissing, bubbling, and gurgling noises are examples of sounds you need to be on the lookout for.

A vacuum can siphon water from the system, resulting in a loud vibrating sound. Having a professional plumber replace the check valve can help fix the problem. A defective flow sensor can also produce noise because the heater will be unable to control gas flow. Other causes include a faulty pressure valve and insufficient ventilation.

As you can see, many things can make your tankless water heater produce unusual noises. That's why it's prudent to have the system examined by a professional.

With the signs highlighted in this guide, you can tell when your tankless water heater has a problem. If your heater is not producing hot water or making weird noises, it's essential to contact a reputable plumber immediately. The same applies if the system has a leaking problem.
