    Tankless brand

    What brands of tankless do you like the best.

    1. Navien
    2. Takagi
    3. Rannia
    I'm trained in all 3 I have a lot of tankless that I serve.

    We've mostly installed Rinnai. Have quite a few out there, both in residental and commercial.

    Recently we have been getting the Error 79 (internal water leak) code come up on the newer ones during a heavy rain storm.

    Seems like rain is finding it's way down the intake pipe from the roof termination. It leaks out of the combustion fan motor into the bottom of the heater and the sensor goes off.

    They have been a good little heater for us besides that.

    I have only seen that error 79 once, it was because an ac duct was blowing rite on the unit, caused condensation in the cabinet. I believe they have a collector for the venting, or you can try piping in a drain...

    hands down. The toughest, most reliable unit I have used.
  • Ditto on Noritz

    Plug it in, turn it on, get 'er done.
    Often wrong, never in doubt.

    I worked for a mechanical contractor who used 3 commercial condensing units in a temporary boiler truck. They managed to keep a medium sized Catholic school warm for a week while I replaced the main boiler during a 0-10* cold snap.
    Have a NC 111 in my house, it needs a little attention after 5 years but really just charging along like a boss.
    The problem Noritz has is that they over-market and are too accessible; thus supply houses here in Denver have been dropping them due to lack of margins.

    Noritz would be my

    second choice, nice unit, I think they weigh like 5 lbs more than any other tankless, lol... But around here support isnt huge, plus when I look at their catalog there are way too many units, customers get confused {me too}, Rinnai has a pretty simple line up, 3 lines a couple sizes in each and that is it... I also feel like Rinnai isnt going anywhere, I have talked to a bunch of the guys and the cs is good, the company seems good, I think in the next 25 years they are still here and going strong, some of the other companies I can not say the same for, in this market companies selling efficient equipment should be chugging along, not slowing down and I feel I see less and less of some brands...

    In my eyes the Rinnai has the same internals as the takagi, at least on there non-condensing unit. There just a tad more difficult to swap out the heat exchangers.
    The takagi had the tm-50 which is almost 400,000 btu. I been seeing a lot of places with 4 to 7 units on the wall. The only thing I see that's bad with theses are the hex going bad or plum wrong,
