Default Are tankless water heaters JUNK?????

I had a plumber ( a highly respected one) tell me that he thought tankless waters are junk. No real explanation, just.... JUNK.

I would be open to anyones opinion on this.

Does anyone own one and can tell me how well they work and if they would recommend getting one???

Default well

If you have well water , they can build up some scale..but so do coils in boilers.
Tankless is the new way of savin water sitting around in a tank. You call for hot water...instant.
I have inspected hundreds and see no real issues yet. Let em sit around a while, and I'll have a different opinion.
For now, fine.
maybe he was thinking condensing heaters...they clog fast in my opinion. It may be metals in the water sticking to the piping...jury still out.

thanks for the reply.... this house has city water so Im not too worried about scale build up. However, I did read somewhere that you need to clean/flush the unit out on a yearly basis. Some sort of "acid" flush. It is recommended that a professional does this flushing process.... how hard could it be to flush it out???

Default Yup

Let the pro's hadle that part, acid...yuck. water draining all over the place if something is broke...yuck.
Kind of like when you take the car to the shop, they see things you do not.
Good luck on your decision.

You can buy junk with any product. Many companies, without knowing all the engineering factors,have jumped into the business. Many Plumbers will install them, but don't do maintenance due to the complexity of them. The small tubing in them can clog, and they are not recommended for hard water installations. Not aware of the yearly cleaning requirements, but it would make sense as a regular water heater should be flushed at least once a year. Then again, you are not storing water in the tankless type. I believe that if you research the brands, you will find one to meet your needs. This is one item where buying the "cheap one" is not recommended.

City water has hardness just like well water. Most people don't understand this, but it's true. Some Cities just have more than others.

Thanks everyone.... All of this information is very helpful!!! I believe that I am going to go with a Bosch or a Rheem model and I may also install a small water softener, however (adding) installing a water softener would take up more room and I am installing tank less water heater to try and GAIN room

Let us know what you think about it... I would love to have a tankless, I currently have a 120 gallon rental unit and it is monstrous, I would like to convert my garage into a den (which I would use as a bedroom) but, with this huge hotwater tank it makes the process more difficult than I want it to be!
Good Luck, and keep us updated!

Default Tankless water heater

NO THEY ARE NOT JUNK !

IF YOU WANT TO HAVE IT INSTALLED CORRECTLY THATS THE PROBLEM MOST
PLUMBERS DON'T KNOW HOW TO INSTALL THEM RIGHT

FIRST YOU NEED IT SIZED FOR YOUR DEMAND LOAD FOR YOUR HOUSE ! !

SECOND YOU NEED SOME EXTRA PARTS TO GO WITH ANY BRAND
*WEBSTONE+EXCLUSIVE+PRODUCTS

THESE VALVES HELP WITH THE INSTALL AND FOLLOW UP MAINTENANCE IN THE
FUTURE

IF YOU DO ALL THIS YOU SHOULD BE VERY HAPPY

Default Tankless water heater

Ms. Shan2themax
you cannot install or have installed any type of gas fired
water heaters in a living area, or space
because of possible carbon monoxide poisoning

this is a national code law by the national fuel gas code !

PLEASE FELL FREE TO GOOGLE CARBON MONOXIDE POISONING
