re: How Long Did Your Tankless Water Heater Last?

I have a 5 year old navien tankless and do the descale/servicing on it myself once a year. There’s a great video on YouTube that goes through the steps.

You’ll need a bucket, sump pump, washing machine hoses and a couple of gallons of vinegar. I did not do it the first couple years and when I dumped the vinegar and it dried on the ground there was a ton of scale. Ever since then I’ve done it yearly and there is not nearly as much.

Really pretty easy if you are at all handy.
