Though tankless water heaters are more expensive upfront than traditional tank water heaters, they are totally worth the price. There are several compelling reasons to switch to a tankless heater. Tankless heaters are more efficient than standard tank heaters, take up less space, use up to 34 percent less energy than storage tank water heaters, and also last longer.

Every household appliance requires regular maintenance, and tankless water heaters are no exception. Regular maintenance reveals current and potential problems. A well-maintained tankless water heater is less likely to break down unexpectedly. Well-maintained units tend to use less energy than poorly maintained systems.

Here are some signs it’s time to maintain your tankless water heater.

A Sudden and Inexplicable Change in Your Water Quality

If your water is rusty or there is too much sediment in it, there may be something amiss. Rusty water is usually caused by a deteriorating anode. Other common causes of rusty water include sediment buildup and faulty piping.

Rusty water does not necessarily mean there is a problem with your tankless water heater. Sometimes, the problem stems from a quality issue at the source. Stop yourself from jumping to conclusions. Has your water been tested? If testing reveals that your water is not receiving proper treatment, install a water treatment system.

If the issue still persists, have a plumber inspect your tankless water heater.

Unusual Noises

Banging, popping, or cracking noises coming from your water heater could indicate a sediment buildup. This is a serious problem and demands immediate attention. If you ignore the issue, your water heater components could fail prematurely, and your unit might stop working. Your plumber will flush out your system to address the problem.

No Hot Water or Inadequate Hot Water

Over time, mineral deposits form. A buildup of minerals can block a water heater’s heating elements, affecting its ability to heat the water. If your water heater does not heat your water at all or heats inconsistently, reach out to a professional for help as soon as possible.

Low Water Pressure

When deposits build up, they can block off the pipes connecting to the unit. As your water struggles to travel past these blockages, it loses pressure. Flushing and cleaning your water heater will remove any buildup.
