Description for AO Smith HYB-90N

The NEXT Hybrid gas water heater is designed to improve upon tankless technology. It's engineered to take the water heating experience to a whole new level. It's built for the way people ACTUALLY live and use hot water. NEXT Hybrid is here and now. NEXT Hybrid is the future of hot water.

How does NEXT Hybrid work?
The NEXT Hybrid water heater features a patented heat transfer process that utilizes a secondary heat exchanger to capture the heated flue gas from the tankless unit and route it back through a buffer tank to extract additional heat. The combined effort of the two technologies creates a superior, more energy-efficient performance.

Conventional water heaters perform well with simultaneous demands because of their stored hot water. However, at times they run out of hot water during long draws because of the lower BTU input. Tankless technology performs well with long draws at steady flow rates. However, due to the lack of storage, they struggle with simultaneous demand from multiple fixtures. Combining the advantages of both technologies, NEXT Hybrid is the best of both worlds!

Combining the best features of tankless and conventional technologies, NEXT Hybrid features:

  • ENERGY EFFICIENCY: Patented circulation system delivers 90% thermal efficiency, ensuring maximum heat transfer, saving money on operating costs compared to a standard 78% efficient conventional or 84% tankless gas water heaters. Condensing design includes condensate drain trap
  • HYBRID TECHNOLOGY:
    • Innovative technology that surpasses existing conventional and tankless designs.
    • Patented water flow circulation system provides the performance of a tankless unit with extremely quick recovery.
    • First hour delivery of 189 gallons of hot water.
    • Smaller than a conventional 50-gallon gas water heater, but with twice the hot water delivery.
    • Whole-home solution regardless of geography
  • IMPROVED HOT WATER DELIVERY:
    • Continuous hot water shower after shower when properly sized for your home
    • No minimum flow rate for ignition
    • No cold water sandwich
    • Delivers hot water faster than tankless
    • Internal storage easily handles peak demand
  • SOPHISTICATED ELECTRONICS:
    • User-friendly integrated temperature controller with LED numeric display allows for precise temperature settings
    • Multiple Lifestyle Modes - Energy Saver, Vacation and Boost modes allow for simple one-touch customization based on specific hot water needs
    • Safety lock feature deters unwanted access
    • Error code display for easy troubleshooting
  • LOWER INSTALLATION COSTS:
    • Utilizes 1/2" gas line standard in most homes today
    • Extremely low exhaust temperature enables PVC venting for easier, more economical installations
    • Less expensive venting material versus stainless steel venting used with most tankless models
    • Hot and cold water connections similar to conventional tank-style models
  • POWER VENT DESIGN
    • Uses inexpensive PVC, CPVC or ABS pipe for exhaust. Canadian installations require ULCS636 listed PVC or CPVC pipe for venting.
    • Can be vented vertically thru-the-roof or horizontally thru-the-wall
    • 2" pipe vents up to 50 equivalent feet
    • 3" pipe vents up to 100 equivalent feet

LOVE THIS WATER HEATER!

Comments about 100,000 BTU NEXT Hybrid Residential Gas Water Heater:

I had this water heater installed to replace 2-40 gallon tanks. It is so awesome! I always ran out of hot water in the shower previously, but now I have to get out of the shower because I am tired of hot water! Every person who has showered in my three bathrooms has had an endless supply of hot water! I love this water heater!
Ease of installation was not bad, only thing that took a while was having to reroute plumbing since I completely took out one hot water heater. I have not experienced any noise from this water heater.

Too much hot water? Nah.

Comments about 100,000 BTU NEXT Hybrid Residential Gas Water Heater:

I really like this water heater. We upgraded from an old AO Smith 40 gal and this one does not run out of hot water. Ever. Atleast, we haven't been able to run it out yet. It is essentially a 25 gallon tank with a tankless heater unit strapped to the front of it, although it does look fancy with it's plastic on the outside.

Pros:
-I don't think it can run out of hot water and I'll believe this until proven otherwise.
-This unit did fit between the rafters in the attic when we lifted it up and the plastic on the sides can be removed to gain a bit of clearance.
-Smaller than a tank water heater, but not small. -No clearance required.
-Simple electronics and error codes

Cons:
-Price.
-You do have to install a condensation line for this heater which is tough if you don't already have one.
-The exhaust vent is required to be PVC, which we had to change from the old metal roof vent.
-The gas line is required to be solid pipe all the way to the unit, no flex line. The solid line doesn't seem to quite line up with the hole in the side of the plastic on the unit.
-Last, the plastic door hits the drip pan (we used a 28", I would recommend this size) it's sitting in, so we had to sit it on blocks in the pan.
-The unit can be heard faintly through the ceiling when it is running, but this is not noticable unless directly below it and it does not run often (except when hot water is running).

I give it 5 stars because it works so well so far. The price point may still be too high, but it is a great product.

    Q:

    Does the unit have dedicated make up (combustion) air piping?
    I do not see in schematic.

    • VERIFIED BUYER

      A:

      No. It only has a power vent and uses room air for combustion. I installed mine in a closet and was required to add two air vents. One high an one low, typically the vents are installed on closet doors.

      Answered on 10/11/2012 by Anonymous
    • VERIFIED BUYER

      A:

      If I understand your question correctly, no. Just exhaust vent. The unit
      draws combustion air from the surrounding air, so if you have a confined
      space, that space should be ducted -- there's no pipe fitting on the
      machine, as far as I know, for dedicated combustion air intake.

    Can this be used where the temperature of the incoming water is 40 degrees
    Asked on 6/12/2012 by tom

    • VERIFIED BUYER

      A:

      You can expect a recovery 90 degree F rise at 121 gallons per hour. That
      means you would get water at 130 degrees. This does seem to be pushing the
      outer limits but still adequate. For a final confirmation I would call AO
      Smith with your question.

      A:

      Yes - but consider desired outlet temperature to determine how long heater
      can sustain it (tank is very small). Unit does have a 100K BTU burner
      (make sure your gas supply can support rate of flow).

      A:

      It will actually work better than other demand heaters as it will keeps a
      tank heated for high flow rates that others would not manage. Then it will
      continue to heat the tank until it is at the set temperature.

    Q:

    APPARENTLY THIS UNIT WILL PRODUCE 121 GALLONS/HOUR AT 90 DEGREES RISE.
    HOW MUCH OUTPUT PER HOUR IF WE SET IT TO 120 OR 130 DEGREES [ TEMP. OUTPUT ]? THAT IS 30-40 DEGREES HIGHER THAN YOUR SPEC.
    AVERAGE TEMP. IN ROOM WILL BE 72 DEGREES IF THAT MATTERS.
    PLEASE ADVISE.

      Hello - had this unit for a year and can report the following:
      My cold water temp ~55 degrees f, hot water set point = 140 degrees f so
      effectively an 85 degree rise. Was able to get 2 gpm (unlimited hot water)
      at that rate. Having said that, you better have an adequately sized gas
      line particularly if you have other gas appliances kicking on during water
      heat operation - burner = 100K BTU. Unit produces per spec.
      I can not recommend this heater - after 11 months of use unit fell
      unreliable, had AO Smith replace with a Vertex which I love (so far)..

      A:

      I can't give you an exact answer. However, I can give you an idea of what I
      have seen so far. We have had this water heater for about 4 months now.
      I have the water heater itself set to 140 F and a mixing valve that knocks
      the output down to 125F. Our water heater is located in the attic, in
      February in Mississippi, it was probably around 60 or 70 degrees in the
      attic this year. However the unit is well enough insulated that i'm not
      sure the external temp matters much.
      It seems that we can run 2 showers for at least 30 minutes with no drop in
      temperature. We could probably run them much longer.
      If I run a shower while a large size jetted bathtub is filling, I did
      notice a drop in temperature just a couple minutes before the tub was full,
      probably down to 90 degrees or so. When the tub was turned off, the water
      was back to full temperature in under a minute.
      Hope this helps some.

      A:

      It is a 100,000 Btu heat engine and that is the limit. However, you have
      20 gal that is 9 degrees below the set temp. The storage will get through
      most uses and unless there is a continued high draw it will not run out.
      It is restoring the storage while you draw off it so it has a head start.
      Your question would be difficult to calculate but depends on how you use it.

      Answered on 3/27/2012 by Another PexSupply Customer
    • VERIFIED BUYER

      A:

      Hello,
      Quick answer: You're computing temp rise from zero, not from ground temperature.
      That is incorrect. Underground water supply pipes across the country vary from
      about 40º-75º this means a theoretical rise to 130º- 165º based on the 90º
      specification. 120º-130º settings should be well within the 90º rise
      specification as long as your incoming water is not under 35º- 40º, and then you
      have other problems and are risking frozen pipes.
      This water heater produces 189 gallons of hot water during the first hour and
      121 gallons per hour of constant use after that at 90º rise. It has three
      heating modes: Vacation: 90º, Energy Saver: 100º-135º, and Boost Mode:
      140º-158º. I have mine set at 118º and it works really well.
      If you want to optimize the output of this heater I would definitely use 3/4"
      gas pipe to supply this heater. 1/2" gas is an option, but why starve the
      heater. This heater also works really well with hot water recirculation systems
      because it has a 25 gallon holding tank to feed from. The only time I've seen
      the heater not keep up with use was when a very large 85 gallon whirlpool tub
      plumbed with 3/4' pipe was opened up all of the way (85 gallons in 8 minutes
      will tax any heater). For all normal appliances plumbed with 1/2" I have never
      lost hot water, even after an hour of constant shower use. FYI, the first time I
      turned on the heater it only took about 8 minutes to heat the entire 25 gallon
      holding tank to 120º.

      This unit will require the same maintenance as a traditional tankless unit. A water softener will help the unit run and last longer.

      Answered on 4/4/2011 by PexSupply Staff from NY
    • A:

      Hard water will cause any hot water heater to clog up faster. (mineral deposits). Have your water tested first to determine if you need a watersoftener.
      Water softeners can cause problems also, such as increasing the conductivity of the water- increasing anode wear. Also water-softeners can leetch salt byproducts, such as sand from flushing cycles downstream to faucets. The water softener resevoir should be cleaned out yearly. The plus side to having soft water is you wont have as much scale build-up inside your plubing.

      A:

      Primarily you would be using the solar as a recirculation loop, which would provide a warmer inlet temperature than the HYB-90N. The HYB-90N will fire when the tank temperature drops approximately 14 degrees below the set point on the HYB-90N.
