How to Descale a Tankless Water Heater Simply and Efficiently!

Tankless water heaters are a technological marvel! A far cry from the traditional tank-type water heater, these wonderful devices render running out of hot water during a soothing bath or shower nothing more than a bad memory! However, as with all precise and high-tech devices, some TLC by means of routine maintenance will be necessary to keep your hot water running for years to come.

For tankless water heaters, Public Enemy No. 1 comes in the form of SCALE, which is the rock-like residue left behind on surfaces they're subject to a water supply that is overly-packed with calcium and magnesium minerals…otherwise known as HARD water. The accumulation of scale inside your tankless water heater can lead to inefficient operation, or even worse: No hot water at all!

Thankfully, there's an INEXPENSIVE and SIMPLE way to remove scale from the internals of your tankless water heater to help keep it humming along for years to come…all you need are a few items and well, this step-by-step video, of course!

Here's what you're gonna need:

-Submersible pump with a 3/4" male HOSE thread outlet. The one I used can be found here:
-Two 5-foot (1.5 meter) washing machine hoses with female ends.
-One to two gallons of household white vinegar
-One five gallon bucket or equivalent container
-Clean rag or paper towels.

OK, you've got everything you need, now GO WATCH THE VIDEO and save your tankless water heater from certain doom!!! 💪

This is unbelievably easy. I got a quote for over $600 to do this. Then I said I had two and they cut me a break to do both for $900!! I already had a submersible pump, so about $50 for the hoses, new bucket, and plenty of vinegar, and I am set for many years. I am appalled by the rates and taking advantage of people who may not know and not being real with them. Thank you so much for great videos like these.

[KienThucDoDay]

this is how instructional video should be. thx so much for the education

[scratchanitch]

And that's how you make a good YT video. Easy to understand, good pace and nothing extraneous. Nice job.

Hello frank! My name is Michael Acocella, when i first got into the trade, you were my pre-apprentice teacher at humber college! I just wanted to thank you for your amazing work ethic and professionalism, I was able to maintain and adhere to your knowledge you gave me all those years ago! Thank you! Keep up the good work! Amazing video

BEST VIDEO OUT THERE TO DESCALE! VERY INFORMATIVE. THANK YOU!

[Last-First]

First of all, thanks for the awesome detailed video and for taking the time to share your knowledge. After watching this, I feel confident I can perform this procedure on my girlfriends tankless water heater. Second, I have watched countless how-to videos on YouTube over the years and your video is the first one I have ever commented on. After watching the video, and reading most of your replies to the comments, it was obviously clear that you have a heart to help others, you have a positive attitude toward difficult situations and life in general, you accept where you are at with your skill level and give confident answers when you know something, but are humble enough to admit when you don't know something, you are very kind and respectful in your comments/answers and never put anyone down, and you are blessed with the gift of encouraging others. You stood out from all the others and this is why I had to comment on this video. If this is who you are in your private life, I know your family and friends are very blessed to know you. If you are a follower of Jesus Christ, your actions show much fruit of the Spirit. If you are not a follower of Jesus Christ, I pray you would have an open heart to seek Him. 🙏 Either way, I pray many blessings to you. Thanks again for the video and comments!!

This video provided me with the information and confidence to service my own tankless (Rheem brand) unit. I watched another video first and the tankless unit in that video had service valves with separate contols for the cold water inlet/ hot water outlet and the service hose connection.

I started to worry I wouldn't be able to self-service my unit and would need to contact a plumber. Luckily I came across this video and you have the exact valves that I have (which I now know as a 3-way valve), down to the yellow tags.

Armed with the proper instructions on how to use this 3-way service valve I plan to descale my unit this week. Thanks for the knowledge I hope I can pay it forward. 👏🏿👏🏿

[Jerseyphil]

This is a very comprehensive, detailed, and clear instructed video for descaling, thank you very much

[StephanieEastwood]

You're such a good teacher, Frank, demonstrating every step of the set-up, & including little extras like the animation showing the direction of flow, and explaining what scale is. I appreciated your multiple camera angles that let us see your hands & tools on every valve & filter. Also helpful and not in any other vid I watched today: the info about pipe vs hose threads, and the possible need to get a male hose adapter for the pump. One small suggestion: I wished you had checked and cleaned the water heater's filter screen *before* you flushed, as well as after. Also, you could show us how to clean the air intake filter too.

[griffmom]

Thank you for this video! We have been getting awful calcification from our hot water only. This makes perfect sense!

[Dani-hqix]

Amazing, that we are charged $250-$400 for this service. Last year the plumber was here less than hour. Crazy. Thanks, might just give it a try myself.

[Tbay]

this was posted 1 year ago, and I just watched it now. Very informative, I did it before but it was a couple of years ago. Glad I am doing it now, Guess I need to make this as my normal routine.

[magskippy]

Finally someone did a video
W the jomar valves where there are service valves . ❤nice job and thank you!

[mickeyvisco]

I am not sure if I ever going to do this but this was a great video

[mikefoster]

Excellent instructional video. Good explanation regarding Jomar 3 way valves.

[michaellegault]

Life Hack, turn the vinegar bottle sideways when pouring. Pours easier and faster without surging/sloshing. Applicable on windshield wiper fluid and any other rectangular liquid container.

[danielvelezdiaz]

Thanks for sharing..don't stop...keep up !!!

[BSnydr]

Great video. Thanks for the education. Why treat the problem if you can prevent the problem? Why not just use a water softener to filter out the hardness?

[NikeMikey]

Love my Bosch. Has top or bottom service ports

[MrGoatman]

To the point! That's what I'm talking about.
Thank you
