Our friend just posted this on Next Door:
We have had two homes with tankless hot water heaters and were never aware that they need annual service to flush, which is costly in and of itself. We are having to replace and the warranty is void because of our ignorance. We are generally very on top of these things but have never been informed of this. Just letting folks know in case you live under the same horribly expensive rock we do!
============================ I don't have one, but am passing on the information for those who have one.

Damn, we've had one for at least 15 years, and there has been no service on it. Yikes, that's something to look forward to within 12 hours of my dh and ds taking off on a week long bike trip. There are always water problems when those two leave. As a matter of fact it was the first father/son bike trip when the old water heater packed it in and I got the tankless one.

Really hope that this doesn’t happen while they are gone. I know how that timing works though. |

I had heard this snd didn’t want to have to deal with it so we didn’t go that route. From the way people talk about how much they love them and there is never any mention of it I would bet that most never do it.

Flushes are about $200-300 once a year so really not that costly. I spend more than that on oil changes and ture rotations a year.
If you don't do it regularly, minerals build up and can eventually block the line and you will have no hot water.

We've had one for a few years and have had it flushed a few times. The last time, the plumber told us that it was really very easy and we can do it ourselves by watching Youtube. That may be the plan for next year's flush.
Best investment in this house that we've ever made, btw!

It's recommended that all water heaters -- tankless or not --- be flushed regularly.

A big factor is how hard your water is as well. We have fairly soft water and I very seldom flush the Keurig, have never flushed a water heater. First one was 22 years old and the current one is 9 years old.

According to the plumbing contractor who installed our most recent water heater (at 1030 pm om a Tuesday), tye tankless ones dont tend to last longer than the regular ones. Between that and the cost to convert to one, we stuck with what we had (plus, it was 1030 pm on a Tuesday and we needed hot water asap!)

We’ve always had tankless and never do annual maintenance.

I was just coming to say the same thing..... in reality all should be flushed on a regular basis, its rare that anyone does. I kind of wish they offered a combo service with either the furnace or AC tune up just so I would remember to do it! |

I love my tankless water heater. It's worth the effort not to run out of hot water. We do have a water softener, so that will extend the life of the water heater.

This, exactly. We own a company that does new construction plumbing and residential service. You wouldn't believe the number of times we go out because people have no idea that things in their homes need regular maintenance. People should really be more informed before buying, and builders should be giving out way more detailed information in their new home and warranty packets. |

I thought I wanted a tankless because of the endless hot water, so they say.
My sister installed one, Thanksgiving came and we began to wash the dishes. We had about a dozen people that day, perhaps 15 tops. Dishwasher was filled (but not started) and we began to wash the pans, and things that would not fit in the dishwasher. Ran out of hot water pretty quickly. That day convinced me I didn't want one. My niece loves hers. I still don't know why my sister's could not provide the hot water it was supposed to provide.

Hers must not have been working correctly. If there is no hot water then the WH is not on. It heats as it goes which is why you don't "run out". There's no storage of hot water to run out of. No hot water means that it is not working. |

No hot water means that it is not working. Exactly this. It very likely threw an error code and no one checked it. The majority of the time, resetting it works. Occasionally there is a real problem and troubleshooting with the manufacturer, or calling a plumber, will fix it pretty quickly. |

If I moved into a house without a tankless heater, it would be the first thing I changed. Honestly, probably even before I unpacked a single box.
I love the tankless water heater.

We don't have one and we have never run out of hot water. Even when we have 5 people taking showers.

First one was 22 years old and the current one is 9 years old. I was wondering about this. Just sent an email to DH to remind him we need to refill the salt in ours this weekend! I don’t think we have ever run out of hot water, and I hope that doesn’t change. It’s just the two of us, but even when we’ve had company I don’t think we have. Of course, we had a 65 gallon tank until this year when we had to replace ours. They no longer make that size commercially and to size up was too expensive (no room) so we had to go smaller. aprilfay21 Is there a good maintenance list you can recommend? |

You only really need to keep the filters cleaned and the tank flushed annually. There are easy to follow troubleshooting guides for most brands' error codes available online, too. We almost exclusively install Navien and Rinnai so those are the ones I'm most familiar with. |

You can sometimes get away with less frequent flushes (I still wouldn't go more than 2 years because you'll still get sediment build up) but it also depends on the effectiveness of your softener. |
