Opal 1.0 vs Opal 2.0 Nugget Ice Maker

The first time I set an Opal 1.0 next to an Opal 2.0 on my kitchen counter, I honestly could not tell them apart from across the room. Same stainless drum, same chunky footprint, same little scoop hanging off the side. The differences hide in the details, and those details are the whole story if you are picking between the two.

I have run both machines for months, filled them, drained them, cleaned them, and pulled ice out of them at 6 a.m. before coffee. So this Opal 1.0 vs Opal 2.0 comparison comes from actually living with them, not from spec sheets alone.

If you are new to this style of ice, the soft chewable nugget kind that soda fountains use, my broader nugget ice maker guide covers the basics. Here I am staying tight on the two GE Profile Opal generations and what changed.

The quick answer on Opal 1.0 vs Opal 2.0

Both machines make the same nugget ice. Same texture, same crunch, same roughly 24 pounds per day rating when conditions are good. If ice quality alone is your deciding factor, you can stop reading and buy whichever is cheaper.

The real gap shows up in three places: the side tank, the WiFi, and a few small design tweaks. The 2.0 was GE’s cleanup pass on the original, and it fixed the things people complained about most.

Feature by feature: the comparison table

The onboard water reservoir is nearly identical between the two, which surprises people. Both hold roughly three pounds of water inside the machine. The capacity difference comes entirely from the optional side tank, and that is the single biggest reason to reach for the 2.0.

The side tank is the headline difference

The Opal 1.0 runs off its internal reservoir only. When that water runs low, ice production slows and then stops until you refill it. In practice that meant walking over with a pitcher a couple times during a party.

The Opal 2.0 accepts a clip-on side tank that adds roughly three-quarters of a gallon of standby water. The machine sips from that tank automatically, so you get a much longer run before anyone has to refill anything. If you want the full breakdown of how that attachment feeds the machine, I wrote about the nugget ice maker side tank separately.

Here is the honest catch: the side tank is an add-on, not a magic capacity boost inside the drum. It does not make ice faster. It just means the machine keeps working longer between fills, which for hands-off use is exactly what most people want.

The side tank does not make more ice. It makes you refill the machine far less often, which feels like more ice.

WiFi and app control

Early Opal 1.0 units shipped with Bluetooth, which meant you had to be standing next to the machine to talk to it. That is close to useless. Later 1.0 runs and the full 2.0 line moved to real WiFi through GE’s SmartHQ app.

With WiFi you can start a batch from bed, check whether the bin is full, and set a schedule so ice is ready by the time you wake up. I set mine to start at 5:30 a.m. and it has fresh nuggets waiting. If app features are what pull you toward the Opal family, the connectivity details in my write-up on nugget ice maker app and WiFi control go deeper.

Design and small refinements

The 2.0 got a handful of quality-of-life tweaks. There is a small light in the ice chute so you can see the nuggets pour, which sounds gimmicky until you are scooping in a dim kitchen. The button layout got cleaner, and GE tightened up some of the internal fittings that owners had flagged as drip points on the 1.0.

The footprint and bin size stayed basically the same. Both hold about three pounds of finished ice in the bin, and neither one keeps that ice frozen, so it slowly melts back into the reservoir and gets remade. That recirculation is normal for this whole category, and I explain why in the piece on nugget ice maker water use and recirculation.

What did not change

• Nugget texture and chew are identical
• Roughly 24 lb per day output ceiling on both
• Similar running wattage in the 130-160 watt range
• Same need for regular cleaning cycles
• Same countertop footprint, no plumbing required

Running cost and power

Neither generation is a power hog, and they draw almost the same amount. Running wattage lands somewhere in the 130-160 watt range depending on how hard the compressor is working, which is roughly what a couple of old incandescent bulbs used. Over a full day of on-and-off cycling you are looking at pennies to a couple of dimes on most residential electric rates.

If you want the arithmetic laid out with real kilowatt-hour math, I did that in the article on nugget ice maker daily run cost. For general appliance efficiency habits, the U.S. Department of Energy’s Energy Saver resource is a solid plain-English reference.

A common mistake with both machines

The mistake I see most often has nothing to do with which generation you buy: people fill the reservoir with hard tap water and never clean the machine. Nugget makers recirculate their own meltwater constantly, so minerals concentrate fast, and scale kills output on a 1.0 and a 2.0 equally.

Run the cleaning cycle on schedule and use filtered water if your tap is hard. You can check your local water hardness through the USGS water hardness science page. A neglected 2.0 will make worse ice than a well-kept 1.0, so upkeep beats generation every time.

Which one should you buy

If you are buying new today, the 2.0 is the easy pick. Side tank support and reliable WiFi are genuine upgrades for anyone who wants to fill the machine, walk away, and come back to ice. The price gap between generations has narrowed a lot, so paying up for the newer unit rarely stings.

The 1.0 still earns its keep if you find one cheap and you are around to refill it. For a lightly used office break room or an occasional-party household, it makes the same great nugget and saves you money. And if you are weighing the whole category first, my take on whether a nugget ice maker is worth it is a good gut check before you spend anything.

Making the call

Both Opal generations make the soft, chewable ice that got you interested in the first place, and on pure ice quality they are twins. The 2.0 wins on the things that make daily life easier: it drinks from a side tank so it runs longer untouched, it talks over WiFi so you can schedule and monitor it, and it smooths over a few rough edges from the original.

Buy the 2.0 if convenience and long unattended runs matter to you. Grab a discounted 1.0 if you want the same ice for less and you do not mind the occasional walk to the pitcher. Either way, keep it clean and feed it soft water, and you will be crunching happily for years.
