Benefits of 6-in-1 Sparkling Water Taps
- The complete water solution – six functions from a single 6 in 1 tap cover every water need in the kitchen, from instant boiling to chilled sparkling, with nothing left out.
- Save time – instant 98°C water, chilled water, sparkling water and clean filtered ambient water all on demand, with no waiting and no separate appliances to manage.
- Reduce energy bills – heat and chill only what you need, rather than running multiple appliances throughout the day.
- Free up worktop space – replace your kettle, filter jug, sparkling water maker, chilled water dispenser and bottled water delivery with a single elegant tap.
- Eco-friendly – less energy waste, less water waste and no more single-use plastic bottles for sparkling or filtered water.
- Better-tasting water – advanced filtration removes chlorine, limescale, heavy metals and other impurities across every filtered function.
- Premium digital control – a precision knurled dial with colour-coded LED indicators gives you complete, intuitive control over all six water functions at a glance.
How Does a 6-in-1 Sparkling Water Tap Work?
- A compact insulated boiler unit sits under your sink, connected to your cold mains supply and a standard 13-amp socket, heating filtered water to up to 98°C and keeping it ready to dispense instantly.
- An integrated under-sink chiller cools filtered water to between 4°C and 10°C, providing refreshing chilled drinking water on demand without a separate fridge dispenser.
- A sparkling water module infuses chilled filtered water with CO2, delivering consistently fizzy sparkling water at the touch of a button.
- An advanced filtration system removes chlorine, heavy metals, limescale and other impurities, improving the taste of your water and protecting the internal components from damage.
- A precision knurled digital control dial with colour-coded LED indicators makes switching between all six functions simple and intuitive.
- Filters should be replaced every six months to maintain performance and warranty coverage.
Switching between boiling, chilled sparkling, chilled filtered, filtered ambient, standard hot and cold water is effortless, with digital controls and a deliberate press-and-hold activation ensuring the boiling function is always used safely.

6 in 1 Boiling Water Taps FAQs
What does a 6-in-1 boiling water tap do?
A 6-in-1 sparkling water tap delivers six distinct water functions from a single tap: filtered boiling water, filtered sparkling water, filtered chilled water, filtered ambient drinking water, unfiltered hot water and unfiltered cold water. This means it replaces your kettle, filter jug, sparkling water maker and chiller in one single unit, freeing up significant worktop space and simplifying your kitchen entirely.
What is the difference between a 5-in-1 and a 6-in-1 boiling water tap?
A 5-in-1 sparkling water tap typically delivers filtered boiling, filtered chilled, filtered sparkling, standard hot and standard cold water. The 6-in-1 Quel Ultimo adds filtered ambient drinking water as a sixth function, giving you clean, filtered water at room temperature alongside all the other options. It also offers a more advanced digital control system, an LED display showing real-time temperature and filter status, and Bluetooth app connectivity for remote control and maintenance reminders.
How is the Quel Ultimo controlled?
The Quel Ultimo is operated via an electronic push-button and handle system with an LED display that shows real-time water temperature, filter life and CO2 levels at a glance. It also connects to a smartphone app via Bluetooth, allowing you to adjust settings, receive maintenance reminders and monitor performance remotely.
What are the water temperature settings on the Quel Ultimo?
The boiling water function can be adjusted between 60°C and 98°C to suit the precise requirements of different hot drinks and cooking tasks. The chilled water reservoir maintains a temperature between 4°C and 10°C, ensuring consistently refreshing filtered cold water on demand.
How does the 6-in-1 sparkling water tap's sparkling water function work?
The Quel Ultimo includes an integrated 425g CO2 cylinder, capable of producing approximately 60 litres of sparkling water, along with the option to connect an external CO2 cylinder for higher-volume use. Carbonation is added to the chilled filtered water automatically, delivering consistently fizzy sparkling water with no additional setup required.
Is the Quel Ultimo energy efficient?
Yes. The Quel Ultimo carries a Class A energy efficiency rating, making it one of the most efficient under-sink water systems available. The insulated boiling reservoir and efficient cooling system are designed to minimise energy consumption across all six functions.
Is next day delivery available?
Yes. Next day delivery is available across the UK on our 6-in-1 boiling water taps. Order before the daily cut-off and your tap will arrive the following day.
Are you the same company as AquaTaps?
Yes. Quel Tap is the new name for Aquataps. Same company, same team, same products, same warranty and the same customer care you’d expect from us. We rebranded in 2026 to better reflect what we’ve always stood for. Everything else stays exactly as it was.
