Commercial ice machine energy and water use
A cafe, bar, food truck, or small restaurant comparing two ice machines needs two rates that are not the brochure pounds: kilowatt-hours per 100 pounds of ice, and gallons of potable water per 100 pounds of ice. This page is how those rates are defined, which federal and ENERGY STAR limits they sit under, and how to turn a published kWh/100 lb figure into a daily and monthly electricity number. It is not a utility quote, not a rebate, and not a health-code letter.
Pounds per day live on how to size a commercial ice machine. Heat in the room, once-through condenser water, and remote condensers live on air-cooled vs water-cooled. Incoming-water temperature bands and clearance live on commercial ice machine installation requirements. Cartridges and scale live on water filters and descalers and how to clean a commercial ice machine.
The rows below are the eCFR text, the ENERGY STAR criteria page, and the manufacturer pages we opened on 2026-10-07. Where two sheets disagree, both cells are printed. We did not average them.
What the two rates mean
Federal definitions in 10 CFR 431.132:
- Energy use is total energy consumed, in kWh per 100 lb of ice. For a remote-condensing machine, that total includes the ice-making mechanism, the compressor, and the remote condenser or condensing unit.
- Potable water use is the potable water used in making ice: ice harvested, plus dump or purge water, plus harvest water, in gal per 100 lb. It excludes condenser water.
- Condenser water use is a third number, only on a water-cooled machine: water through the condensing unit, in gal per 100 lb. It is not the potable figure.
- Harvest rate is pounds of ice at 32°F produced per 24 hours.
An ice-making head (a modular head with no bin of its own) does not include bin or dispenser energy in the reported kWh. A self-contained cabinet includes the ice-making section and the storage compartment in one box. Those are different equipment types. Do not compare a head’s kWh to a dispenser stack as if the dispenser were free.
The DOE test procedure in 10 CFR 431.134 measures harvest rate, energy use, and condenser water use for automatic commercial ice makers up to 4,000 lb/24 h. Potable water use in that section is a voluntary measurement. ENERGY STAR makes potable water a requirement. The federal maximums in 10 CFR 431.136 cap energy and, for water-cooled equipment, condenser water. They do not print a maximum for potable gallons.
The test is 90°F air and 70°F water
DOE’s test procedure uses AHRI Standard 810 (I-P)-2016 with Addendum 1, which it incorporates by reference. Standard rating conditions in section 5.2.1 of that standard:
- Ambient temperature 90.0°F. On a split system, condenser air inlet 90.0°F and indoor ambient 90.0°F.
- Inlet water 70.0°F.
- Inlet pressure while water is being used: 30.0 ± 3.0 psig.
That is the 90/70 column on a spec sheet. The 70°F air / 50°F water column is a second published production number. It is not the harvest rate H in the federal formula.
Manufacturer sheets we opened put the kWh and the potable gallons on the 90/70 header, not on the 70/50 header. Hoshizaki KM-81BAK is the clean example: the KM-81/116 spec dated 05/20/26 prints 98 lb at 70/50, 76 lb at 90/70, 22.0 potable gal/100 lb, condenser N/A, and 5.6 kWh/100 lb. The ENERGY STAR listing for KM-81BAK uses harvest 76, energy 5.6, potable water 22.0. The “up to 98 lb” line is the other column.
Do not multiply 98 lb by 5.6 kWh/100 lb and call the product the rated daily energy. The 5.6 belongs to the 90/70 test.
How to read the utility block
Look for four labels, then stop if one is missing:
- kWh per 100 lb, and whether the header says 90/70.
- Potable gal per 100 lb, same header. This is ice-making water, including purge. It is not the water that ends up in the glass only.
- Condenser gal per 100 lb. Air-cooled sheets print N/A, a dash, or nothing. A large number there is condenser water. That topic stays on air-cooled vs water-cooled.
- Which production cell matches the kWh. Use the 90/70 pounds as harvest rate H when you compare the machine to a federal or ENERGY STAR formula. If the page only says “up to” and does not split 70/50 from 90/70, do not invent H.
| Model in this directory | What that page prints for production | kWh / 100 lb | Potable gal / 100 lb | What we did not fill in |
|---|---|---|---|---|
| Hoshizaki KM-81BAK | Spec 05/20/26: 98 lb at 70/50, 76 lb at 90/70. Self-contained crescent cuber. | 5.6 at 90/70, on the spec and the product page | 22.0 at 90/70. Condenser N/A | ENERGY STAR finder, opened the same day: harvest 76, energy 5.6, potable 22.0, self-contained, batch, certified |
| Manitowoc UYF-0140A | NEO 140/190 asset: half-dice 137 lb at 70/50, 100 lb at 90/70 | 9.2 at 90/70 | 16.7 at 90/70 | That row does not print an ENERGY STAR mark. An older sheet for UY-0140A (no F) prints different pounds and kWh. Do not mix the suffix |
| Scotsman CU50 | Current product page: 65 lb at 70/50, 49 lb at 90/70. Air-cooled. R290 on that page | 11.0. The energy line is not labeled 90/70 | 29.8. Same unlabeled line. Page says technical specs are the air-cooled model | Webstaurant reprint SIS-SS-CU-CU50 01-22 prints 16.44 kWh/100 lb in a 90/70 column, production 64 / 44 lb, refrigerant R-134A, potable still 29.8. That is a different build. We did not merge 11.0 and 16.44 |
| Hoshizaki IM-50BAA-Q | Product page: about 50 lb or 500 spheres / 24 h. No 70/50 vs 90/70 split on that HTML | 15.7 at 90/70 | 69 at 90/70 | No harvest split, so we did not run a federal formula. Sphere ice, not a crescent cuber. See ice types |
| Hoshizaki KM-520MAJ | Product page: about 556 lb. The HTML does not split 90/70 production | 4.68 at 90/70 | 14.7 at 90/70 | No 90/70 pound cell on the page we opened, so H for a formula is not taken from 556 |
| Ice-O-Matic CIM0430A | Webstaurant reprint Rev 9/17: 435 lb at 70/50, 320 lb at 90/70. ChefsDeal reprint Rev 10/20, part C002: 435 lb at 70/50, 310 lb at 90/70 | 5.43 on Rev 9/17; 5.4 on Rev 10/20 | 19.8 on both. Condenser N/A | We did not average 320 and 310, or 5.43 and 5.4. The Rev 10/20 feature line also says “up to 500 lb.” The specification table on that same PDF says 435. We used the table. Use the PDF that matches the serial |
| Hoshizaki F-330BAK | Product page: up to 331 lb flake. No 90/70 production cell on that HTML. Self-contained flaker | 4.29 at 90/70 | 12 at 90/70 | The page says ENERGY STAR qualified. We did not open a finder row for this SKU on this pass, and we did not treat 331 as H |
| Manitowoc RNP0320A | Spec 4988F, 07/22: nugget 308 lb at 70/50, 236 lb at 90/70. Ice-making head | Sheet: 6.88 at 90/70. ENERGY STAR finder for RNP0320A-161: 6.8 | Sheet: 12 gal. Finder: 12.0 | Finder harvest is 259 lb/day, not the sheet’s 236. Ice hardness factor on the finder: 85.0. Continuous type. The sheet marks ENERGY STAR 3.0. We did not average 6.88 and 6.8, or 236 and 259 |
| Scotsman C0330MA-1 | Portal spec SIS-SS-PP-C0330 01-22: air-cooled 400 lb at 70/50, 288 lb at 90/70. Medium cube, modular head | 6.23 at 90/70 | 18.0 at 90/70. Condenser column is a dash | Same sheet, water-cooled sibling C0330MW-1: 4.97 kWh/100 lb and condenser 139.0 gal/100 lb. The directory file’s 6.92 kWh figure is not this sheet. We did not use it |
Scotsman C0330MA-1 on that portal spec is the air-cooled 115 V row: 6.23 kWh/100 lb and 18.0 gal/100 lb at 90/70, condenser column a dash. The 208–230 V air-cooled sibling C0330MA-32 prints the same 6.23 and 18.0. The water-cooled sibling C0330MW-1 prints 4.97 kWh/100 lb and 139.0 gal/100 lb of condenser water. Lower kWh, a new water line. That trade is the air-cooled vs water-cooled page. A 6.92 kWh figure in the directory file does not appear on this 01-22 spec. We are not using it.
A lower kWh/100 lb is less electricity per pound of ice at the test condition. It is not a smaller machine, and it is not the same ice. IM-50BAA-Q at 15.7 kWh and 69 gal is a sphere program. KM-81BAK at 5.6 kWh and 22 gal is a crescent cuber. F-330BAK at 4.29 kWh and 12 gal is flake. Compare inside one ice type, then decide whether you wanted that ice.
Federal standards: 10 CFR 431.136
10 CFR 431.136, as opened 2026-10-07, still prints the levels for equipment manufactured on or after January 28, 2018. Batch type (alternate freeze and harvest, including cube) is paragraph (c). Continuous type (freeze and harvest at the same time; flake and nugget are the usual ones) is paragraph (d). Both cover capacities from 50 to 4,000 lb per 24 hours. H in the formulas is harvest rate in pounds per 24 hours.
Paragraph (b) is the older cube-type table, for machines manufactured on or after January 1, 2010 and before January 28, 2018. A machine built last year is not on that table.
An editorial note on part 431 says amendments made effective December 23, 2024 (89 FR 91163) were removed on September 9, 2025 (90 FR 43371), and the affected sections reverted. The tables below are the ones in the section we opened, source note 80 FR 4754, January 28, 2015. A May 16, 2025 proposed rule (90 FR 20919) discusses rescinding amended condenser-water limits. That proposal is not the table quoted here.
Equipment types in the current tables:
- Ice-making head — no integral storage bin.
- Remote condensing, but not remote compressor — the condenser is remote; the compressor stays with the head.
- Remote condensing and remote compressor — both are remote.
- Self-contained — ice-making mechanism and storage in one cabinet.
- Cooling is air or water. Air-cooled condenser water is NA.
The condenser-water footnote on both (c) and (d): water use is for the condenser only and does not include potable water used to make ice.
Air-cooled energy caps (manufactured on or after January 28, 2018)
These are maximum kWh/100 lb. A published number at or under the cap for that row can be legal and still miss ENERGY STAR. ENERGY STAR is the next section.
| Type | Equipment | Harvest rate H (lb ice / 24 h) | Maximum energy use (kWh/100 lb) |
|---|---|---|---|
| Batch | Ice-making head, air | < 300 | 10−0.01233H |
| Batch | Ice-making head, air | ≥ 300 and < 800 | 7.05−0.0025H |
| Batch | Ice-making head, air | ≥ 800 and < 1,500 | 5.55−0.00063H |
| Batch | Ice-making head, air | ≥ 1,500 and < 4,000 | 4.61 |
| Batch | Remote condensing, not remote compressor, air | < 988 | 7.97−0.00342H |
| Batch | Remote condensing, not remote compressor, air | ≥ 988 and < 4,000 | 4.59 |
| Batch | Remote condensing and remote compressor, air | < 930 | 7.97−0.00342H |
| Batch | Remote condensing and remote compressor, air | ≥ 930 and < 4,000 | 4.79 |
| Batch | Self-contained, air | < 110 | 14.79−0.0469H |
| Batch | Self-contained, air | ≥ 110 and < 200 | 12.42−0.02533H |
| Batch | Self-contained, air | ≥ 200 and < 4,000 | 7.35 |
| Continuous | Ice-making head, air | < 310 | 9.19−0.00629H |
| Continuous | Ice-making head, air | ≥ 310 and < 820 | 8.23−0.0032H |
| Continuous | Ice-making head, air | ≥ 820 and < 4,000 | 5.61 |
| Continuous | Remote condensing, not remote compressor, air | < 800 | 9.7−0.0058H |
| Continuous | Remote condensing, not remote compressor, air | ≥ 800 and < 4,000 | 5.06 |
| Continuous | Remote condensing and remote compressor, air | < 800 | 9.9−0.0058H |
| Continuous | Remote condensing and remote compressor, air | ≥ 800 and < 4,000 | 5.26 |
| Continuous | Self-contained, air | < 200 | 14.22−0.03H |
| Continuous | Self-contained, air | ≥ 200 and < 700 | 9.47−0.00624H |
| Continuous | Self-contained, air | ≥ 700 and < 4,000 | 5.1 |
Water-cooled energy caps are in the same eCFR paragraphs. They are tighter on kWh than the air-cooled row in the same harvest band, and they add a condenser-water cap. Two condenser-water formulas small buyers run into, from paragraph (c), batch, ice-making head, water-cooled: 200−0.022H gal/100 lb when H is under 2,500, and 145 gal/100 lb from 2,500 up to 4,000. Self-contained batch water-cooled condenser water is 191−0.0315H under 2,500 lb, and 112 from 2,500 up to 4,000. Continuous water-cooled condenser formulas are different (paragraph (d): ice-making head 180−0.0198H under 2,500, then 130.5). Read the row that matches the suffix. A published condenser figure in the 100s is normal for once-through cooling and is still a lot of water. Machine examples already cited on the air-cooled vs water-cooled page are not repeated here.
Two machines against the air-cooled self-contained cap
KM-81BAK. Self-contained, air-cooled, batch. H = 76 (the 90/70 cell, and the ENERGY STAR harvest).
Federal maximum = 14.79 − 0.0469×76. 0.0469×76 = 3.5644. 14.79 − 3.5644 = 11.2256 kWh/100 lb. The sheet’s 5.6 is under that cap. This is our arithmetic on the published formula. It is not a DOE certification printout.
UYF-0140A. Same equipment class. H = 100 from the 90/70 cell on the NEO asset.
Federal maximum = 14.79 − 0.0469×100 = 14.79 − 4.69 = 10.10 kWh/100 lb. The sheet’s 9.2 is under that cap. Same caveat: arithmetic on the formula, not a certification letter.
Continuous machines get an ice-hardness adjustment in the DOE test procedure before the reported energy use. Batch machines do not. The ENERGY STAR finder says the same thing in its energy-use description: continuous reported energy is measured energy times the ice-hardness adjustment factor; batch ice hardness is taken as 100 percent. Do not “correct” a flake or nugget kWh by hand.
ENERGY STAR Version 3.0
The criteria page states that certified models meet Version 3.0, effective January 28, 2018. The specification’s scope:
- Included: air-cooled batch or continuous ice makers that are an ice-making head (IMH), a remote condensing unit (RCU), or a self-contained unit (SCU). An air-cooled RCU built for a remote rack compressor can qualify if that same model number is also sold with a dedicated remote condensing unit, and the rating is the dedicated unit.
- Excluded: water-cooled ice makers; ice makers with ice and water dispensing systems; air-cooled RCUs designed only for a remote rack compressor.
Harvest-rate bands in the tables run up to 4,000 lb/24 h. Energy and potable water both have to clear. H is pounds of ice per 24 hours. Potable water in these tables is one cap per equipment type, not a different cap in every harvest band.
Version 3.0 says to measure energy use with 10 CFR 431.134, and potable water use with AHRI Standard 810-2007 with Addendum 1. DOE’s representation rule for energy, on or after October 27, 2023, points at AHRI 810-2016 with Addendum 1. Those are the two sentences the documents print. We are not blending them into one test method.
| Ice | Equipment | Harvest rate H (lb / 24 h) | Energy (kWh/100 lb) | Potable water (gal/100 lb) |

KM-81BAK against Version 3.0. Air-cooled batch SCU, H = 76, which is under 110.
Energy cap = 12.57 − 0.0399×76. 0.0399×76 = 3.0324. 12.57 − 3.0324 = 9.5376 kWh/100 lb. Potable cap = 25.0 gal/100 lb. The finder and the spec both print 5.6 kWh and 22.0 gal. The finder says certified. Our arithmetic is a check you can repeat. The certification is the finder’s, not ours.
UYF-0140A against the same SCU band. H = 100.
Energy cap = 12.57 − 0.0399×100 = 12.57 − 3.99 = 8.58 kWh/100 lb. Potable cap = 25.0. The NEO asset prints 9.2 kWh and 16.7 gal. 16.7 is under 25.0. 9.2 is over 8.58. The asset row we read does not claim ENERGY STAR. Confirm the exact suffix in the ENERGY STAR commercial ice machine finder before you treat a missing mark, or a brand-page logo, as the listing.
A manufacturer page that says “ENERGY STAR qualified” is that page’s statement. KM-81BAK and RNP0320A-161 are finder rows we opened. F-330BAK’s product page says qualified; we did not open its finder row. CIM0430A’s Rev 9/17 sheet puts an ENERGY STAR mark on the model; we did not open its finder row. The finder is the list.
Air-cooled, water-cooled, and remote
Cooling type changes which water and energy numbers exist. It does not change the ice into a different product.
- Air-cooled. Condenser water is not a line item. Heat leaves into the room (KM-81BAK heat rejection on the product page is 1,800 BTU/h; other BTU/h examples are already on the air-cooled vs water-cooled page). Electricity is the compressor, the fan, and the harvest. Most cafe, bar, and food-truck machines in this directory are this class. A food truck is the food-truck guide: air-cooled, and condenser water is not available.
- Water-cooled. You still have potable ice-making water, plus condenser gallons per 100 lb, which the federal cap measures separately. The kWh cap for a water-cooled class is not the air-cooled formula. Many cities restrict once-through condenser water. That choice, and the published condenser-gallon examples, stay on the air-cooled vs water-cooled page.
- Remote air-cooled. The condenser (and, on some models, the compressor) sits elsewhere. DOE’s energy-use definition still counts that remote unit’s energy in the kWh/100 lb. Condenser water stays NA if the remote unit is air-cooled. Refrigerant lines and a matched condensing unit are an install, not a utility cell. The air-cooled guide treats a remote sheet as an HVAC project. We do not list a remote SKU in the directory.
Worked example: kWh/100 lb to a month
Published input: KM-81BAK, 5.6 kWh per 100 lb at 90/70, from the 05/20/26 spec and the product page.
The rate is energy while ice is being made at that test condition, per 100 lb harvested. It is not a 24-hour meter reading. We did not find a published standby watt figure for this model, so standby, a drain pump, and the kitchen air conditioner that has to remove the 1,800 BTU/h are not in the dollars below.
Per 100 lb harvested. 5.6 kWh of ice-making electricity.
Example day of 100 lb. One hundred pounds is an example operating assumption. It is not the 76 lb 90/70 rating and not the 98 lb 70/50 rating.
- Ice-making electricity that day = 5.6 × (100 / 100) = 5.6 kWh.
- A 30-day month at that same 100 lb every day = 5.6 × 30 = 168 kWh.
- Example electricity rate: $0.15 per kWh. This is an example for the arithmetic. It is not a utility quote, not a demand charge, and not a national average.
- 168 × 0.15 = $25.20 of ice-making electricity in that 30-day example.
Same machine, at the rated 90/70 harvest of 76 lb, if it actually made that much.
- 5.6 × (76 / 100) = 4.256 kWh that day.
- 4.256 × 30 = 127.68 kWh.
- 127.68 × 0.15 = 19.152, which is $19.15 at this example rate if you round the dollars to the cent.
Potable water uses the same pounds. The spec’s 22.0 gal per 100 lb at 90/70 means 22.0 gallons of potable water for the 100 lb example day, and 22.0 × 0.76 = 16.72 gallons for a 76 lb day. That 22.0 already includes purge and harvest water. USGS Circular 1268 prints 1 gallon = 8.34 pounds. 100 ÷ 8.34 = 11.99 gallons of water weight in 100 lb. 22.0 − 11.99 = 10.01 gallons in that 100 lb example that did not stay as ice. We are not pricing the water. There is no water rate in this example.
If the room is hotter than the rating, or the inlet water is warmer, the machine will not hold the 70/50 pounds. KM-81BAK’s own pair is 98 lb versus 76 lb. The only kWh cell on that spec is the 90/70 cell. We are not inventing a second kWh number for a 70/50 room or for a kitchen past 90°F.
What moves the number after the machine is in
The rated kWh/100 lb is a clean machine at 90°F air, 70°F water, and about 30 psig. A cafe does not live in that room.
- Air and water temperature. Stay inside the manual’s range, then expect the 90/70 pounds if the kitchen is hot. KM-81BAK’s spec: ambient 45–100°F, water 45–90°F. Other brands print other bands. The installation guide already tables them (Manitowoc NEO ambient 40–110°F on the family sheet; Scotsman CU50 ambient 50–100°F in the user manual). We are not adding a percent “hot kitchen kWh penalty.” The sheets we opened did not print one.
- Air path. A blocked louver or a dirty condenser coil cuts harvest. Front-breathing cabinets such as KM-81BAK have a removable air filter. Clearance is the installation page, not a new rule here.
- Scale and the water filter. A scaled evaporator and a starved inlet cut the pounds you get for each hour the compressor runs. The filter page and the cleaning page are the intervals and the cartridges. ENERGY STAR does not replace either one. We are not publishing a “percent saved by descaling” figure. We do not have one from these sheets.
- Ice type and harvest. A sphere machine’s 15.7 kWh/100 lb is the cost of that ice form. Switching to a crescent cuber changes the ice, not just the bill. Size the pounds on the sizing guide first, then multiply those pounds by the kWh/100 lb from the 90/70 cell.
What this page is not
- Not an electric bill and not a water bill. The $0.15/kWh figure is an example rate. Demand charges, taxes, and a sewer charge on condenser water are not in it.
- Not a rebate. We are not stating a dollar rebate. Check the finder and the utility if a rebate is the reason for the logo.
- Not the cooling-type page, the install page, or the sizing page. Those links are above so this page does not restate them.
- Not a health-code opinion and not a permit. NSF marks and the installation manual are what you show an inspector.
