Gas tankless Hot water heater cleaning recommendations
 

We need to have the TANKLESS gas hot water heater cleaned, looking for any recommendations and approximate cost. . down to the penny not needed

thanks in advance

Just had our one year home inspection. Asked same question. Apparently although recommended by the manufacturer, no need to be done yearly.

Apparently there are DIY kits on Amazon around $100. And basically easy to do.

We just watched a neighbor have a plumber, that hooked up the system, then sat in his truck for half hour while it’s being flushed. Cost was $300, although couple have had it done with a plumber for $250.

Then there is a guy ( always a guy in everyone’s neighborhood) charging $100.

We used these (Rinaii) in the laundromats I managed; usually 6 per store. The quality of the town's water determined the frequency of flushing. Some stores needed it every 4 to 6 months; others could go 2 years. If you have a quality filtering system I'd expect you can get longer than 1 year. Be certain to clean the stainless steel screens on the inlet valve if they need it.

Lowes sells a do-it-yourself kits for ~$150.
(probably Home Depot as well)

Easy to do.................highly recommend.

I bought the kit and can now do it as often as I chose, which is once a year. It's very easy to do and takes only a little basic plumbing knowledge and three gallons of vinegar. There are several YouTube videos that show you how.

I just use a sump pump in a bucket of vinegar and flush through for 3 hours. Just need the pump and the short hoses to connect to the heater inlet and outlet. Shut off the heater, close the valves to the house and open the flush valves. Easy peasy.

What frequency are most of you using?

Well, that is great nooz to me! As a confirmed DIY hack, I am up and good with doing it myself to save $150-200 if there are youtube directions. . . .

MANY THANKS!

I'm not sure in Florida. I do my house in MA yearly. But it depends on how hard the water is. You are basically doing it to remove mineral build up.
