4-in-1 Chilled Tap

The 4-in-1 chilled tap combines four water functions in one kitchen faucet: mains hot water, mains cold water, filtered 98°C near-boiling water, and filtered chilled water at approximately 4°C. A dedicated digital boiler and under-sink chiller work with the filtration system to provide both hot and cold filtered drinking water from the same tap.

For kitchen brands, importers, distributors, and project buyers, the key difference is the temperature range. Instead of dispensing filtered water at the temperature of the incoming mains supply, this 4-in-1 chilled water tap can deliver filtered drinking water at approximately 4°C, while the boiling-water function reaches 98°C.

4-in-1 Chilled Tap Specification

*Typical values supplied for this product description; actual incoming-water temperature depends on installation conditions and local water supply.

The 4-in-1 chilled tap is built around four clearly defined water functions.

This gives the faucet a working temperature range of roughly 4°C to 98°C.

That matters in everyday use. Chilled filtered water can be dispensed directly into a drinking bottle, while filtered near-boiling water is ready for tea, coffee, cooking, and other hot-water applications. Normal mains hot and cold water remain available through the mixer function.

A conventional 4-in-1 boiling water tap normally combines:

• Mains cold water
• Mains hot water
• Filtered boiling water
• Filtered water

The 4-in-1 chilled tap changes the fourth function from ordinary filtered water to actively chilled filtered water.

The distinction is simple:

Incoming mains water can often be around 12–15°C, depending on location and season. The dedicated chiller takes the filtered drinking-water temperature down to approximately 4°C.

For buyers developing a premium kitchen water system, that additional refrigeration stage is the main technical difference between an ordinary boiling-water tap and a genuine chilled-and-boiling configuration.

The faucet itself is only the visible part of the system. Heating and cooling are handled by dedicated equipment installed beneath the kitchen sink.

The supplied configuration uses a 2.4-litre digital boiler tank as the hot-water component. The tank heats filtered water and maintains the selected temperature until water is dispensed.

The chilled-water side uses a dedicated under-sink chiller to bring filtered drinking water down to approximately 4°C.

This architecture keeps the thermal equipment out of sight while allowing the faucet to provide four different water functions.

The basic water path is:

Mains water → filtration →

Boiler → filtered 98°C water

Chiller → filtered 4°C water

At the same time, the conventional mixer channels provide:

• Mains hot water
• Mains cold water

The exact internal waterway arrangement, connections, chiller specification, and electrical configuration should be confirmed against the selected production model.

Boiling water requires more deliberate operation than ordinary mains water. The digital control system therefore uses a safety activation process to reduce the chance of accidental boiling-water dispensing.

The boiler tank maintains the selected temperature, while the faucet provides the user interface for selecting the required function.

The supplied system supports boiling-water temperature adjustment through the digital tank interface, with settings available between 45°C and 98°C.

The actual control interface and available temperature presets should be confirmed for the selected model.

One of the main engineering advantages of a 4-in-1 chilled tap is that the filtered drinking-water circuit can support both thermal extremes.

The same filtered-water supply can be routed toward:

• Heating: up to 98°C
• or
• Cooling: approximately 4°C

This makes the product different from a standard kitchen mixer with an added boiling-water outlet. The system is designed around a combination of filtration + heating + cooling + conventional hot/cold mixing.

For kitchen manufacturers and water filtration companies, this integrated architecture also creates more options for product configuration. The filter, boiler, chiller and faucet can be specified as a complete drinking-water package instead of treating each component as an independent appliance.

The 4-in-1 chilled tap range can be developed around different kitchen layouts and design requirements.

Available configurations include:

Available surface finishes include:

• CP: Chrome
• BN: Brushed nickel
• BG: Brushed gold
• MB: Matt black
• Copper
• GM: Gun metal

For private-label projects, the final finish, handle configuration, faucet geometry, logo treatment, and packaging should be confirmed during product development.

The under-sink architecture is particularly relevant when cabinet space is limited.

A conventional kitchen may require a kettle, water filter, separate drinking-water outlet, and bottled-water storage. A 4-in-1 chilled tap can consolidate several of these functions into one integrated system.

The main installation considerations are:

• Boiler tank location
• Chiller location
• Filter access
• Electrical connection
• Water inlet connection
• Faucet mounting position
• Tubing routing
• Maintenance clearance

Cabinet ventilation for the refrigeration unit where required

The actual cabinet dimensions should always be checked against the selected boiler, chiller and filter models before installation.

The supplied warranty structure is:

For distributors and private-label buyers, warranty terms should be included in the final commercial specification and matched to the exact product configuration supplied.

The supplied operating estimate for the boiling-water tap system is approximately 10–15 pence per day, depending on usage.

This figure should not be treated as a universal operating cost. Actual consumption depends on:

• Number of boiling-water cycles
• Selected water temperature
• Daily water volume
• Incoming water temperature
• Ambient temperature
• Insulation performance
• Standby duration
• Chiller operating time

The insulated boiler reduces unnecessary heat loss while maintaining the selected water temperature. For commercial buyers, the correct way to evaluate operating cost is to compare measured daily energy consumption under a defined usage profile rather than relying on a single household estimate.
