Franke CT-200 Little Butler Under Sink Water Filtration Chiller Tank, White
The Franke CT-200 Little Butler is a small, tank-based chiller designed to fit beneath most sinks without taking up much space. It provides instant cold water, which is a major convenience for everyday hydration. Compared with larger units, it excels in saving cabinet space but falls short on capacity, offering only about 1 gallon per hour. Its main advantage is the combination of filtration and cooling in a compact package, though it requires additional hoses and potentially professional installation. This model is perfect for users who prioritize space and quick access to cold water but can accept a limited flow rate and the need for setup assistance.
Pros:- Compact design fits in tight spaces
- Provides instant cold water
- Enhances water taste and quality
Cons:- Requires additional hoses for installation
- Limited capacity (up to 1 gallon per hour)
- May need professional installation
Best for: Small kitchens or apartments with limited space and a need for instant cold water
Not ideal for: High-volume households or commercial settings requiring larger capacity
- Container Type:Tank

It provides instant chilled water, with a capacity of about 0.53 gallons, which is sufficient for daily use but may require refilling in busy households. Its space-saving design includes dual hot and cold options, adding to its versatility. Compared with the Franke, it offers better filtration and temperature control but involves more complex installation, often requiring professional help. This pick makes sense for users who want a customizable, filtered, chilled water experience without sacrificing space.

Factors to Consider When Choosing Under Sink Water Chiller
When selecting an under sink water chiller, consider your household size, water consumption habits, space constraints, and preferred features. The ideal unit provides enough cold water for your daily needs, offers effective filtration, and fits within your available cabinet space. Installation complexity and ongoing maintenance are also key factors, especially for those unfamiliar with plumbing setups. Here, I explore the main points to keep in mind before making your decision.Capacity and Usage Needs
Think about how much cold water your household consumes daily. If you have a large family or host frequently, a high-capacity chiller like the Avalon model makes sense, ensuring continuous supply without frequent refills. Smaller households or apartment dwellers might prefer the compact Franke CT-200, which offers instant cold water but with limited output. Balance your water needs with the available space to avoid overbuying or underestimating your demand.
Filtration and Water Quality
Effective filtration improves taste and removes contaminants. If water quality is a concern, models with multi-stage NSF-certified filters, like the Frizzlife CW5000+MS99 and Avalon, provide peace of mind. For basic needs, activated carbon filtration in the Franke can suffice, but it may not remove all impurities. Consider your local water source when choosing filtration features to ensure safe, clean hydration.
Installation and Maintenance
Installation complexity varies across models. The Franke CT-200 is straightforward but may require professional help due to additional hoses. The Frizzlife unit involves more plumbing adjustments, and the Avalon system demands a comprehensive setup with its included kit. Maintenance includes replacing filters—typically every 6 months for high-capacity models—and periodic checks. For those uncomfortable with plumbing, hiring a professional could add to the overall cost but ensures proper setup.
Size and Space Constraints
Measure your under-sink space carefully. Compact models like the Franke are ideal for tight cabinets, while larger units like the Avalon require more room but provide higher capacity. Consider whether the unit’s dimensions fit comfortably without blocking access to other plumbing or storage areas. If space is very limited, prioritize models with a slim profile, even if it means sacrificing capacity.
Frequently Asked Questions
How difficult is it to install an under sink water chiller?
Installation difficulty depends on the model. The Franke CT-200 generally requires basic plumbing skills and may involve connecting hoses and mounting the unit beneath your sink. The Frizzlife CW5000+MS99 involves similar steps but offers additional features that might complicate setup. The Avalon high-capacity chiller comes with a full installation kit, but its larger size and dual filtration system can make installation more complex, often warranting professional help for a secure and leak-free setup.
Can these chillers provide enough cold water for a family gathering?
The capacity of each model varies. The Franke CT-200 is suitable for small daily use but will struggle during larger gatherings. The Frizzlife unit offers a moderate flow, enough for typical daily hydration but may need refilling during extended events. The Avalon high-capacity chiller is designed for continuous, high-volume cooling, making it the best option for events or busy households that demand large amounts of cold water at once.
How often do I need to replace filters in these systems?
The replacement frequency depends on usage and the specific model. The Franke CT-200, with its small tank, generally requires less frequent filter changes, possibly annually. The Frizzlife system recommends filter replacements every 6 to 12 months, depending on water quality and usage. The Avalon system’s dual filters last about 6 months or 1500 gallons, making it suitable for heavy use but requiring more regular maintenance to maintain water quality.
Are under sink water chillers energy-efficient?
Most under sink chillers are designed to be energy-efficient, especially models with insulated tanks and low power consumption components. The Franke CT-200, being compact and tank-based, uses minimal power. The Frizzlife unit’s adjustable temperature and energy-saving modes help reduce consumption. Larger systems like the Avalon may draw more power due to higher capacity, but overall, they are still more efficient than running a refrigerator or bottled water dispenser continuously. Checking specific energy ratings can provide more clarity.
What maintenance is required besides filter replacement?
Besides regular filter changes, most systems benefit from periodic cleaning of the unit’s interior and checking for leaks or blockages. The Franke CT-200, with its simple design, generally requires minimal maintenance. The Frizzlife and Avalon units might need more attention, such as disinfecting the tank or cleaning the filters’ housings to prevent mold or bacteria buildup. Following the manufacturer’s guidelines ensures the system runs smoothly and maintains water quality over time.
Conclusion
For small households or those with limited space, the Franke CT-200 offers a quick, space-efficient solution with basic filtration needs. Families seeking more control over water temperature and quality, and willing to handle slightly more complex installation, will appreciate the Frizzlife CW5000+MS99. Larger households or commercial spaces that require high-volume cooling and minimal maintenance will find the Avalon high-capacity chiller to be the most suitable choice, despite its more involved setup. Ultimately, your decision should hinge on your specific water consumption, space availability, and preference for filtration features.
