Best Built-In Ice Machine for a Home Bar: Scotsman CU50G ​ ​ A-1A

AMAZON Technical Details Brand Name Scotsman Item Weight 100.0 pounds Product Dimensions 22 x 14.9 x 34.4 inches Installation Type free standing/built-in Special Features control panel informs about water condition Color silver

Pros Make clear ice cubes

Can be installed undercounter

Large cubes Cons Noisy

The Scotsman CU50GA-1A is our top pick for home bars because it produces clear gourmet ice cubes. This type of ice not only looks more elegant in your favorite drink, but it’s also melts slower. It has a front exhaust so you can easily install it undercounter. You can also use it as a freestanding ice maker. Best Features 1. 65lbs Production capacity The Scotsman CU50GA-1A is big both regarding physical size and production capacity. It can produce up to 65lbs of ice, enough to serve an entire bar. In fact, this ice machine was designed for commercial applications. But it’s just as perfect for your home bar. If you love inviting guests over often or holding parties at home, this ice maker is great. It can store 26lbs of ice and will automatically stop making more ice until you empty the bin. 2. Gourmet Ice Cubes The Scotsman CU50GA-1A produces clear and hard gourmet ice cubes. It’s the same kind of ice you’d find at a high-end restaurant or bar. Because it melts very slowly, it’s ideal for cocktails, premium wines, and spirits. Each cube measures roughly 1" x 1.13" x 1.25". 3. Water Quality Sensor An integrated sensor continually monitors the quality of water coming in. If it senses hard water, the machine automatically flushes away the minerals after every ice making cycle. This prevents the buildup of scale which can lower the quality of ice and reduce the machine’s lifespan. Concerns The machine can get a bit noisy especially when the ice cubes, which are quite large, are falling into the bin. AMAZON

It’s true that most undercounter ice machines are expensive. The best ones cost no less than $600 with some such as the 65-lbs Scotsman gourmet ice maker going over $1,000. But you don’t have to resort to portable ice makers you are on a budget. The EdgeStar IB120SS is great undercounter ice maker that costs just $300. It doesn’t produce as much ice as other undercounter ice machines, but it produces enough for most families. Unlike many pricey ice machines, this one has an integrated freezer. So you can store your ice as long as you want. Best Features 1. 12lb Production And 6lb Storage Capacity The EdgeStar IB120SS can produce 12lbs of ice per day.

Once it gets full, it stops making ice until it is emptied.

2. Freezer Function The storage bin doubles up as an integrated freezer. Unlike most ice makers where you can’t leave the ice cubes inside for long lest they melt, you can store your ice cubes in this ice maker for however long you need. 3. Front Venting The EdgeStar IB120SS has a front-vented design. This means you can safely use it as a built-in ice maker. You can also leave it freestanding. The black cabinet and stainless steel door combo look very stylish and modern. Concerns It’s a little loud.

The Whynter UIM-502SS ice maker produces 50lbs of ice a day. That’s similar to the amount of ice produced by many restaurants and bar commercial ice makers. The ice is clear and hard. It’s not the quick-melting cloudy kind your freezer makes. Best Features 1. 50lbs Production And 25lbs Storage Capacity This is one of the best commercial-capacity ice makers.

Pros Durable

Minimalistic design

Daily ice rate of up to 23 lbs Cons Requires a 1/4 inch outside diameter water line

This all-black undercounter ice maker looks stylish, but it’ll cost you quite a bit; around $1,100 to be specific.The price tag is especially surprising considering that it produces less ice than most undercounter units. But most customers say it’s one of the best units they have ever owned. It is super quiet, makes ice fast and is easy to use. It also has an integrated freezer function. Best Features 1. 23 lbs Production + 12 lbs Storage Capacity The ice maker produces around 23 lbs of ice per day. This is plenty enough for most homes even with guests over.

So you can leave your ice in there as long as you want without worrying about it melting. 3. Accepts Custom Panel You can reverse the door’s opening orientation. If you want a more customized look that blends in perfectly with your kitchen, the U-Line BI95B-00 ice maker accepts custom panels. See the manual for installation instructions. Concerns For its price, it’s disappointing that this ice maker does not make gourmet ice cubes.

Koldfront KIM450BL Built-in

Clear Ice Maker

AMAZON Technical Details Brand Name Koldfront Item Weight 76.7 pounds Product Dimensions 23.4 x 14.6 x 32.6 inches Capacity 25 lbs Installation Type built-in/freestanding Special Features Up to 50 lbs. of ice production/day Color black

Pros Insulated ice storage

Simple installation

Removable ice bin Cons Noisy

This is a cheaper alternative to the Scotsman CU50GA-1Agourmet ice maker. It produces clear ice and even though it has less production capacity, 50lbs of ice a day is still a lot and more than enough for most homes.

Best Features 1. 50lbs Production And 25lbs Storage Capacity The Koldfront KIM450BL can make up to 50lbs of ice every day. At full capacity, it can easily serve a bar or restaurant. At home, it’s perfect for large families and those who love hosting often. It’s also ideal for offices. The removable bin can store 25lbs of ice cubes. Note that this ice maker has no freezer function. As soon as your ice cubes are ready, take them out and store them in your freezer. Otherwise, they’ll start melting after a couple of hours. 2.

3. Gourmet Ice Cubes The Koldfront KIM450BL produces restaurant-quality ice cubes. They look elegant and melt much more slowly than traditional ice. Concerns The main complaint from customers is that the ice maker produces sheets of ice that are hard to break. Some users have found a button in the back panel to adjust the sheet thickness and make it easier to break it into cubes. Unfortunately, the manual doesn’t mention anything about this.

Best for the Kitchen: Sunpentown IM-150US Ice Maker with Freezer

AMAZON Technical Details Brand Name SUNPENTOWN Item Weight 55 pounds Product Dimensions 18 x 15 x 25 inches Installation Type built-in/freestanding Special Features reversible door Color silver/black

Pros Built-in or free standing application

Front exhaust

Reversible door Cons Small Ice production

A major limitation with most ice makers is that they cannot store ice cubes for long. If you leave them in for too long, they begin to melt. This is because most units don't have a freezer function. The Sunpentown IM-150US is different. In addition to making ice, it can also store it for however long you want. The storage bin is located within a built-in freezer. This is the main reason we selected it as the best undercounter ice maker for kitchens. Most families don’t need to use all the ice at once. Being able to store it for long comes in handy. You don’t have to make new ice cubes every time you need some, and there’s no need to use precious refrigerator space to store the ice cubes. Another reason we recommend it for most kitchens is that it provides the best value for money. It costs around $380. For that, you get a stylish built-in ice maker, high production capacity, and a freezer storage bin Another reason we recommend it for most kitchens is that it provides the. It costs around. For that, you get a

Best Features 1. 12 Pounds Production And 6 Pounds Storage Capacity The Sunpentown IM-150US produces up to 12lbs of crescent-shaped ice cubes every 24 hours. The storage bin can only hold half that amount at a time. When the ice bin fills up, the machine will automatically stop making more ice. 2. Built-In/Freestanding Design You can use the Sunpentown IM-150US as a built-in or freestanding ice maker. The front ventilation ensures the machine functions normally if you decide to install it under your counter.

Take note of its dimensions (15W x 18D x 25H inches) to make sure it will fit undercounter or wherever else you plan to install it. 3. Stylish Design With Reversible Door The ice maker’s stainless steel door blends in well with your cabinetry. The door is reversible so you can position it how you want based on your kitchen design and personal preferences.

4. Built-in freezer An excellent feature that allows you to store ready-made ice for a long time. It won't melt and you won't have to drain the melted water. Concerns Installation is a bit of a hassle. The manufacturer highly recommends calling a licensed plumber. But even with a pro doing the installation, most customers still experienced a few hitches. It takes some work to get the ice maker working properly.

Best Outdoor Ice Maker:

SPT IM-600US Stainless Steel Under-Counter Ice Maker

AMAZON Technical Details Brand Name SPT Item Weight 84 pounds Product Dimensions 23.6 x 14.6 x 32.8 inches Capacity 1.67 cubic feet Installation Type built-in/freestanding Special Features auto shut off when ice bin is full Color silver

Pros Perfectly clear ice

Reversible door

Store 25 lbs of ice Cons Must use filtered water

With a 50lb ice production capacity, the SPT IM-600US undercounter ice maker is big enough for small and mid-size offices, or even summer cafes and patios. The reversible stainless steel door and front exhaust makes installation easier and ensures it blends in well.

Best Features 1. 50lb Production And 25lb Storage Capacity 50lbs is plenty enough ice to keep everyone drinks in the office chilled. The bin stores up to 25lbs of ice at a time. So you can leave the machine making ice overnight, and you’ll find the bin full in the morning. If you want to start on another batch immediately, empty the ice cubes and store them in a freezer. The ice maker won’t work if the bin is full. 2. Gourmet Ice Cubes The SPT IM-600US produces crystal clear gourmet ice cubes that melt slowly and don’t dilute drinks.

3. Reversible Stainless Steel Door The stainless steel door can be reversed to open from the opposite side. This makes it easy to install the ice maker fit the available space. Regarding style, the stainless steel finish looks great and blends well with other cabinetry. Concerns The ice comes out as a sheet instead of cubes. You have to break them up. If you buy this ice maker, also buy a stainless steel scoop to break the ice. The plastic one that is included is practically useless.

Best Commercial Undercounter Ice Machine:

Orien FS-55IM 44-Pound Built-In Undercounter Ice Maker

AMAZON Technical Details Brand Name Orien Item Weight 113 pounds Product Dimensions 23 x 14.6 x 33.5 inches Installation built-in/freestanding Special Features CFC -free Color silver/black

Pros Air-cooled condenser

Automatic overflow protection

CFC -Free Cons Expensive

This Energy-Star Approved undercounter ice maker is great for those who want a lot of clear ice cubes. Because it needs a line-in and gravity drain, professional installation is highly recommended.

Best Features 1. Clear Ice Cubes The Orien FS-55IM produces clear gourmet ice cubes measuring around ¾” x ¾.” To ensure the best quality ice cubes, the manufacturer recommends using an inline water filter. The ice cubes are ideal for cocktails, spirits and premium liquor. They melt slowly and look more elegant. 2. 44lbs Production And 25lbs Storage Capacity The ice maker can produce up to 44lbs of ice per day. The removable storage bin can hold 25lbs of ice. When it fills up, the inbuilt overflow protection switches off the unit until you empty the bin or the ice cubes melt.

3. Reversible Door Depending on your space and personal preferences, you can reverse the opening orientation of the stainless steel door. Concerns As is the case with many large ice makers, this one tends to make a bit of noise especially if it is freestanding. Most of the noise comes from ice cubes falling into the storage bin.

Undercounter Ice Machines: What To Look For When Buying

1. Ice Quality There are different types of drink ice. The best one for you depends on your needs. If you want the ice for your cocktails whiskey, look for a unit that makes clear ice. If you want soft chewable ice, get a unit that makes nugget ice. Also check the size of the ice cubes, how fast they melt in drinks and their shape. 2. Daily Ice Making Capacity The ice making capacity, also called the production capacity, is the amount of ice a unit can make in a 24hr period. The right figure will depend on your needs. If you need a lot of ice through the day, we recommend a 40lb+ ice maker. If the ice machine serves just 1 or 2 people, even a budget 12lbs undercounter ice maker will do. 3. Storage Bin The next important figure to look for after production capacity is storage capacity. This is the maximum amount of ice a unit’s storage bin can hold. It’s often half the production capacity. For instance, an undercounter ice maker with 45lbs production capacity will have a 25lb storage capacity. The more ice you need, the higher the storage capacity should be. Another feature of the storage bin to consider is whether it is insulated or refrigerated. Most models have insulated bins meaning stored ice will melt after some time. Such ice makers often require a drain connection to get rid of melted water. Other models have a refrigerated storage bin. Your ice cubes will stay solid even if you leave them there for days. These models often don’t need a drainage connection. We recommended a refrigerated ice maker. Surprisingly, refrigerated models are not always the most expensive. If anything, most $1,000+ under counter ice machines have insulated rather than refrigerated bins. You are more likely to find an ice maker with a freezer in less expensive models.

4. Drainage There are three kinds of situations possible when talking about ice machine drainage: no drainage, gravity drainage or pump drainage. Of course, no drainage ice machines are the most convenient and easiest to install. Refrigerated ice makers usually don’t need any drainage. Gravity drainage ice makers require a hose to be connected to the unit from where waste or melted water can flow out through gravity. If your sink or kitchen drain is not accessible via gravity, you’ll need a model that can work with a pump drain. A pump drain can drain the melted water into a sink or drain located higher than the unit. 5. Cooling System Compressors in ice makers can be cooled by either air or water. Almost all modern ice machines use air-cooled compressors. Vents and fans circulate air from the room inside the unit to cool the compressor down. The hot air is vented out, and cooler air is taken in to continue the cooling process. Air-cooled units use more energy and can increase air conditioning costs (because of the hot air released).But they don’t need any extra water other than the one used for making ice. A water-cooled unit uses water to cool the system. The hot ‘used’ water is taken out through the drain. Water-cooled units use much less electricity but need a lot of water to function. That’s why they are being pushed out of the market. When shopping for an undercounter ice machine, buy an air-cooled one. 6. Water Supply You don’t have much choice here since all undercounter ice machines require a line-in. You don’t add water to a reservoir like in smaller ice makers. Note that most many manufacturers recommend installing an inline water filter to maintain ice quality and protect the ice maker. Only one unit above, the Scotsman CU50GA-1A, has a water quality sensor that detects hard water and automatically clears mineral buildup. 7. Cleaning and Maintenance Look for a unit that is easy to clean and maintain. Some units have a CLEAN button. When you press it, it automatically runs water through the unit and drains it. For most undercounter units, however, it’s always a good idea to call a professional if something is wrong. They have complex systems and numerous components that you can easily damage when trying to repair. 8. Other Features Check whether the unit has a reversible door. This is important as it gives you the freedom to install the ice maker where you want without any walls or cabinetry hindering the door from opening properly. On the same note, check whether you can use a custom panel. It allows you to customize the style of your ice machine. Finally, read customer reviews to find out how noisy the unit is. While all units will produce some noise, others won’t give you any peace when they are running. Avoid them.

How Ice Machines Work

The premise of all ice machines, whether portable, freestanding or undercounter, is that they turn water into ice. The actual process is much more involved and requires several parts to pull off. At the heart of an ice machine is a compressor. The compressor pushes a refrigerant (in the form of a gas) through a series of tubes collectively called a condenser. In the condenser, the refrigerant is cooled by either water or air. That’s what the terms water and air-cooled ice makers refer to. If it is a water cooled machine, the cooling water is taken out through the drain. If it is an air cooled ice machine, the warm air is exhausted from vents either at the back or the front. The liquid moves on to a part called the evaporator. Here, it absorbs heat from the environment and turns back into a gas. There is water constantly pouring over the evaporator. It gradually cools down as it loses heat and turns into ice. The ice forms as several cubes connected to a sheet. It is pushed out by a piston or by heating the surface below them. As they fall into the bin, they break up into individual cubes (but not always – sometimes you have to do the breaking yourself). The evaporator can be designed to produce ice in various shapes such as full cubes, half cubes, bullets or pebbles. In nugget ice makers, the final process is a bit different. The evaporator is in the form of a cylinder and water freezes on the inside walls. An auger then scrapes the ice out in the form of soft chewable flakes. Of course, the specifics may differ from one ice maker to another. For instance, gourmet ice makers use a more involved process to ensure the ice is clear and hard. But this is howice cubes are made when you push a button on your ice machine.
