    Question Tankless Water Heater Installation Cost?

    I know it's hard to generalize, but I'm looking at a tankless WH installation, one of the smaller units such as a Rinnai 2020W, Nortiz 63S or Taguchi Jr. My bathroom is completely gutted and the 3/4" hot/cold run right to the outside wall on which the unit will mount. Need 30' of 3/4" gas line run in the attic (cut into an existing line). What's a reasonable range for this sort of job?

    $900 to $1500 easily. Anything less is a newbie trying to make a buck.

    Rugged,
    Is that with/without tankless HWH? I can tell you that the one quote I got was almost 3X the top of your range.

    Not RUGGED but yes, that would be without the heater.

    It is not surprising that you got a price 3X higher.

    What part of the country do you live in?

    Talking tankless heaters in INDY

    their is one BIG advertiseing plumbing company in our town that is
    now playing up the tanklesswater heaters big time....


    a sales man comes out to your home in a suit and tie
    and gives you this big sales pitch about how much you
    are gonna save ect--ect

    the final bottom line price for a gas tankless unit

    runs $4500.


    this place looks for every angle to make a buck
    any way they can.....and I suppose they get
    their fair share of suckers---thats what the advertiseing is for.

    we installed a normal tank type brad white 50 gal for 750

    Default reasonable

    Since we are not going to drive to your location to install the heater, our "reasonable" price would have no bearing on your installation. A reasonable price in your area would probably be whatever the average is between several quotations.

    I'm talking labor only, no materials. I wouldn't touch one less than $1900 in labor, just because.

    I'm in California so I expect to pay more. It can be very difficult to get multiple quotes especially as I'm in a pretty small town south of San Jose. I'm more than willing to pay a fair cost-based price including material overhead and such and I recognize the inefficiency of a small one-day job, but I'm finding pricing for these small residential jobs to be much more market-based. I guess that's life.

    I guess my question would be why you want to spend literally thousands of dollars for an item that you will never recoup the cost? It just won't happen with a tankless. And you will have to take that device apart and clean it of calcium buildup in the heating compartment to keep it running as efficient as the day it was installed. Along with having a service tech on a short rope to help you spend 100's on that unit when things go wrong.

    On one of these forums I had a comeback that, "Do you know how expensive square footage is in California is?" when I made a statement that the square footage you gain is a bad reason to install a tankless over a tank water heater. I don't buy that lame excuse. Closet space is closet space, buy ventilated shelving and work around your situations.

    I mean if you want to be in the in crowd and have something that only a select few have in your area, go for it. Wave of future designs have their setbacks in many ways, give it 20 years and they might be price competitive to the tank water heaters.

    Remember, history always repeats itself; Remember the old RUUD water heaters that worked solely off pressure? Instant hot water water, some are still working today. Huge coil of copper piping inside the cast iron heater and when there was a fluctuation of pressure the heater kicked on and there is your hot water.

    If you go forward with this, go with a 9-12 gpm flow tankless, especially if you have any square footage to the house you have to mention of. GOOD LUCK
