Yes, You Need to Flush Your Tankless Water Heater

One big benefit of having a tankless water heater is not waiting for the whole tank of water to heat up (because there isn’t one). It just keeps flowing, so that epic hot shower never has to end. Because of this, it’s easy to disassociate problems of a tank water heater from tankless, but there are still some common problems at the end of the day.

When you call for tankless water heater maintenance in Brighton, you may not have to worry about pooling sediment at the bottom of a tank unit, but minerals are still a thing, and you can still get buildup. Let’s explain everything.

You Get Mineral Buildup

No tank doesn’t equate to “no problem.” In fact, mineral buildup is still a thing, and because there’s no huge tank where minerals can build up at the bottom, it’s even more critical that you get annual maintenance to ensure this doesn’t cause major problems for your tankless water heater.

There’s less room for error with a tankless unit, so let’s talk about the signs you need to look for in a tankless water heater to know if it needs to be flushed or not. Keep in mind this isn’t a definitive list, but it is a collection of the most common reasons.

Signs That Your Tankless Water Heater Needs to be Flushed

It’s good to look out for your tankless water heater so you can see when problems are coming down the pipeline. We know that’s a terrible pun, but really, you should look out for these problems:

  • Slowed Water Flow: Water comes out slower when you have scale buildup. It’s not really noticeable at first, but over time you realize that the hot water flows so much slower than the cold tap when you turn it on.
  • Longer Wait for Hot Water: Tankless water heaters can take 10 seconds or so to start producing hot water, but that time isn’t supposed to increase. If it’s taking 30 seconds now when it used to take 10, all to get hot water, there’s a problem.
  • Lower Water Temperature: Your tankless water heater does its job well, but eventually, the water hitting your hands is more warm than hot. That’s a big red flag that something is wrong.
