Your water heater may need tankless maintenance if you answered “yes” to any of these not-so-fun bullet points. You might have even bigger problems if your plumber did not tell you that a tankless heater needs maintenance.

Why are we so confident about this? We have serviced tankless units in the Glendale, CA area for more than 14 years and have seen almost everything. This post will explain the differences between tankless and regular maintenance, as well as the reasons why they are important for protecting your water heater.

Tankless Maintenance Basics

But what does tankless water heater maintenance mean? There are two types:

  • Internal –Cleaning water from the parts.
  • External – Cleaning items like filters, fans, and so on.

You can prevent your tankless water heater from going out of service by maintaining its internal and exterior components. This will also save you a lot of money on repair and replacement costs. You can avoid having to deal with such situations by scheduling maintenance appointments well in advance.

Tired from not getting enough sleep, you get up and go. Although you don’t feel like doing anything, you must get through a lot of tasks. You decide to take a hot shower to get you going. You get up and walk to the bathroom. Then you wait for the water to turn on. You wait. Wait. There is no hot water. Only terrible ice-cold.

You’ll be miserable if you have to deal with this situation. You have more than just a bad mood if your local Glendale, CA Plumber is unable to get you in for the week. It’s best to plan ahead before it becomes a problem.

Maintenance of an Internal Tankless Water Heater

What do you think of flushing when you hear it? If you don’t know tankless maintenance, you might think of a toilet.

Cleaning a tankless water heater involves cleaning the pipes with a liquid.

What is the purpose of a local Glendale, CA Plumber cleaning these pipes? It is due to limescale and hard water. It’s the white stuff that clogs your fixtures. White buildup is especially common in tankless water heaters, which heat water.

It’s as simple as this:

Tankless water heaters are like coffee machines. It won’t function if it isn’t cleaned out frequently. Manufacturers include a flushing solution with every attachment to the coffee machine. Mix the mixture with water, and then run it through your system several times.

A local Glendale, CA Plumber will use a cleaning solution to clean a tankless water heater. It takes about an hour for the pipe to be cleaned.

External Tankless Water Heater Maintenance

This is the most important part of tankless water heater maintenance. External maintenance. Block your plumber’s number if they don’t perform this. They aren’t doing a thorough cleaning of your unit. These things can still block your water heater.

  • Infestations by bugs
  • Fur or feathers
  • Nests of animals
  • Leaves
  • Dirt

Gross right? These are the most important things to do for your tankless water heater. They can either get in through the wind or wiggle in.

An example is: Leaves from a tree placed next to your tankless water heater will cause damage to the tankless unit.

Other components that plumbers should service in a tankless maintenance call are:

  • Fresh intake valve and fan motor –Cleaned using an air compressor to reduce energy wastage
  • Filters- Designed to protect the unit from dirt and grime.
  • Assembly and Burner – Cleaned in order to ensure they work correctly.
  • Gas and manifolds –Inspected to ensure they are at stable pressures and functioning correctly.
  • Inspected for proper levels and easy ignition.

These are the same thing as not changing your car’s oil or doing any other things to it. A water heater and car won’t last forever. External maintenance is something that your local Glendale, CA Plumber should do. It should take no more than 30 minutes.

Are you ready to schedule your tankless maintenance?

You should schedule at least one yearly maintenance appointment for your tankless water heater. Make sure that your plumber inspects the inside and outside of your tankless water heater. If your tankless doesn’t get serviced regularly, it could be dangerous.

People with large homes, trees that shed a lot of foliage, or who have really hard water must get maintenance done every six months. You might think that you don’t need to maintain your water heater if there aren’t any problems. Even though you don’t see it, there are issues that are developing behind the scenes.
