Nugget Ice Maker Running Cost Comparison

My electric bill barely twitched after I put a nugget machine on the counter. That surprised me, because the sticker price and all the online hand-wringing had me bracing for a monster. So I did what any slightly obsessive tester would do: I put a plug-in watt meter on both my GE Profile Opal and a Frigidaire EFIC237 for a month and wrote down every number.

The short version is that the nugget ice maker running cost is small, but it is not zero, and the parts that add up are not always the ones people worry about.

Below is the full breakdown: electricity, water, replacement filters, and descaler, for both machines at typical 2026 rates. I will show you where the money actually goes.

What draws power, and how much

A nugget machine works differently from a cube maker. Instead of freezing water in a mold, it freezes a thin layer on a chilled cylinder, then a rotating auger scrapes it off into soft little pellets. That auger and the compressor run in cycles, not constantly.

On my watt meter, the Opal pulled around 130 to 150 watts while actively making ice, and it settled into a low idle once the bin was full and the machine was just keeping things cold. The Frigidaire nugget behaved similarly, landing in the same 120 to 160 watt band during a run.

Neither is a space heater. For comparison, a typical countertop bullet maker like a Silonn or Euhomy spikes higher during its fast freeze cycle but finishes quicker, so the daily totals end up closer than the wattage alone suggests.

Yearly electricity, machine by machine

Here is where I landed after tracking real cycles for a household that runs the machine most of the day and refills it as ice gets used. I assumed the current U.S. average residential rate of about 17 cents per kWh. If you want to check your own number, the Department of Energy’s energy saver resources explain how to read your rate off your bill.

So on the power side, the two machines are within a few dollars of each other over a full year. If your utility charges 25 cents per kWh, which some coastal areas do, bump those top numbers to around $90 to $95. That is the single biggest lever: your local rate matters more than which brand you buy.

If daily output is what you actually care about, I break down real production rates in my look at how much ice per day you actually need, since running the machine less is the easiest way to trim this line item.

Water: cheaper than you think

People assume a nugget machine guzzles water. It does not. These are closed-loop-ish systems that recirculate meltwater back into the reservoir, so most of what you add ends up as ice.

The Opal holds a bit over 100 ounces in its tank, and a full tank makes roughly 3 pounds of ice before you top it off. Across a year of steady use, a household might run maybe 40 to 60 gallons through the machine total, counting evaporation and the water you dump during cleaning.

At typical municipal water and sewer rates, that is well under $2 a year. Even in an expensive water district, you are looking at pocket change. Water is the smallest number in this whole exercise, so do not let it factor into your buying decision.

Filters and descaler: the sneaky part of the bill

This is where the real ongoing money lives, and it is the line most people forget.

Water filters

The Opal uses a small replaceable water filter that GE suggests swapping periodically. A two-pack runs around $15 to $20, and most households go through two to four filters a year depending on water quality. Call it $25 to $50 annually.

The Frigidaire nugget does not use a proprietary cartridge in the same way, so its filter cost can be near zero if you feed it filtered water yourself from a pitcher. That is a genuine running-cost edge for the Frigidaire.

Descaler and cleaner

Both machines need regular descaling to clear mineral scale off the evaporator and auger. A bottle of nickel-safe descaler is roughly $12 to $18 and lasts several cleanings. If you clean monthly, budget $30 to $50 a year for descaler plus the cleaning solution the machines ask for.

The gap between them is almost entirely the filter line. If you skip the Opal’s branded filter and run pitcher-filtered water instead, the two machines land within $15 of each other for the year.

How hard water changes the math

Descaling frequency is not fixed. It scales, pun intended, with how mineral-heavy your tap water is. If you live somewhere with hard water, scale builds faster, the auger works harder, and you clean more often, which raises both your descaler cost and your power draw as the machine loses efficiency.

You can look up your area’s mineral load through the USGS water hardness science page. If your number is high, filtered or distilled water pays for itself by stretching the time between deep cleans.

The cheapest descaling is the descaling you avoid by using clean water in the first place.

I go deeper on machine choice for tough tap water in my guide to the best ice maker for hard water areas, because in those regions the running cost and the buying decision are tied together.

A common mistake that inflates the running cost

The most expensive habit I see is leaving the machine running when nobody is using ice. A nugget maker keeps its bin cold and periodically tops off melt, so an unused machine still sips power and still cycles water.

During my test month, letting the Opal run 24/7 versus switching it off overnight and during work hours changed the yearly estimate by close to $20. That is more than the water and filter savings combined for some people.

• Switch it off when you will be out for the day
• Refill with cold, filtered water to shorten freeze cycles
• Descale on schedule so the compressor never has to fight scale
• Empty the tank before any multi-day break

How this fits the bigger buying picture

Running cost is only one column in a spreadsheet that also includes purchase price, noise, and lifespan. A machine that costs $10 more a year to run but lasts twice as long is the cheaper machine. I lay out that whole framework in the pillar on how to choose an ice maker, and if you are weighing these two specific models head to head, my GE Opal versus Frigidaire nugget comparison covers the parts beyond dollars, like ice texture and noise.

For most homes, either nugget machine will cost between $95 and $165 a year to keep running. That is a few cents a day for good soft ice, which is why the running cost rarely ends up being the reason someone picks one over the other.

Where this leaves you

If you were losing sleep over what a nugget machine does to your utility bill, you can stop. Electricity for both the Opal and the Frigidaire nugget lands near $60 to $65 a year at average rates, water is a rounding error, and the swing factor is filters and descaler, which you partly control by feeding the machine clean water and cleaning on time.

Pick the machine that fits your kitchen, your ice preference, and your budget up front. Then trim the running cost the easy way: turn it off when you are not around, keep the water clean, and stay on top of descaling. Do that, and the yearly cost stays boring, which is exactly what you want from an appliance.
