What to Look for Before Buying the Best 18 Inch Undercounter Ice Maker
1. Find Your Need - Compatibility and use case considerations
Before purchasing, determine where the unit will be placed and how much ice you actually need. If you are a casual entertainer, a 60-80 pound daily output is sufficient. For busy bars or large offices, look for machines producing 100-130 pounds. Ensure the unit is front-vented if it is going inside a cabinet, otherwise, it may overheat and fail prematurely.
2. Budget - Setting realistic price expectations ($X-$Y ranges)
Expect to spend between $400 and $700 for a solid residential model. Professional clear ice makers or units with built-in drain pumps often fall in the $800 to $1,500 range. While cheaper options exist, they often lack the insulation and durability required for long-term undercounter use.
3. Key Features - Most important technical specifications
Look for an automatic self-cleaning cycle to prevent mineral buildup. Digital LCD screens are helpful for monitoring ice-making status and troubleshooting error codes. Adjustable ice thickness is another premium feature that allows you to customize the cubes for specific beverages like whiskey or smoothies.
4. Quality & Durability - What to look for in construction
Stainless steel is the gold standard for exterior construction because it resists rust and is easy to sanitize. Check for three-layer insulation in the storage bin, which keeps the ice from melting quickly and reduces the frequency of the compressor turning on, extending the machines life.
5. Brand Reputation - Importance of established manufacturers
Choose brands with a history in refrigeration like KoolMore, EUHOMY, or Summit. These companies offer better warranties and have replacement parts readily available. Established brands are also more likely to provide ETL or DOE certifications, ensuring safety and energy efficiency.
6. Portability/Size - Considerations for space and storage
Standard undercounter slots are 18 inches wide, but many high-performance machines are 15 inches wide. A 15-inch model provides more breathing room for the unit or allows for a small filler panel. Always measure the height of your counter to ensure the unit will fit, especially if you have ADA-compliant lower counters.
Is it A Wise Decision to Buy 18 inch undercounter ice maker?
Investing in an 18 inch undercounter ice maker is a wise decision for anyone who values convenience and high-quality beverages. Modern refrigerators often have slow ice makers that produce cloudy, odorous cubes. A dedicated undercounter unit provides a consistent supply of fresh ice that is specifically designed for better taste and slower melting. This is particularly beneficial for those who host gatherings, as it eliminates the need to buy and transport heavy bags of ice from the store.
Compared to portable countertop models, undercounter units offer significantly higher storage capacity and more durable components. While the initial cost and installation might seem high, the long-term benefits of having a professional-grade appliance that enhances your kitchen’s functionality are undeniable. It also adds value to your home, as built-in appliances are often viewed as premium upgrades by potential buyers. For those who frequently entertain or enjoy high-end cocktails, the investment pays for itself in convenience and quality within the first year of use.
What Is the Best Way to Choose 18 inch undercounter ice maker?
The best way to choose an ice maker is to start by assessing your drainage situation. If you have a floor drain nearby, a gravity-drain model is the most cost-effective. If your drain is located higher up, such as in a sink, you must choose a model with a built-in pump or purchase an external one. This single factor will narrow your choices significantly and prevent installation headaches.
Next, decide on the ice type. Crescent ice is great for everyday use and large quantities, while clear square ice is superior for cocktails because it doesn’t dilute the drink as quickly. Once you have these basics settled, look for user-friendly features like a 24-hour timer and self-cleaning mode. Avoid the mistake of buying a machine purely based on the lowest price; instead, look for units with ETL or DOE certifications which guarantee a certain level of build quality and energy savings. Finally, ensure the brand offers at least a 1-year warranty and has a responsive customer support team to handle any technical issues.
