How Does a Quooker System Work?
A Quooker tap is a modern kitchen upgrade that delivers instant boiling water straight from your tap — no kettle required. It’s efficient, safe, and space-saving, making it a popular feature in contemporary homes. But how does it actually work? Let’s take a look inside the system.
In short: A Quooker combines a boiling water tank beneath your sink with a specially designed, insulated tap that dispenses 100°C water on demand — instantly, safely, and without waste.
The Key Components
1) The Boiling Water Tank
The Quooker tank sits discreetly under your sink. It keeps a small amount of water (typically 3–7 litres) at a constant near-boiling temperature using high-vacuum insulation. This means it uses surprisingly little energy — about the same as a low-energy light bulb on standby.
- Water is stored under pressure, so it doesn’t evaporate.
- The system reheats instantly after use to stay ready.
- Most models connect directly to your cold-water supply.
2) The Quooker Tap
From the outside, it looks like a sleek kitchen mixer tap — but inside, it’s built to handle extreme temperatures safely. The spout is insulated, and the handle uses a push-and-turn motion to prevent accidental activation.
- Dispenses boiling, hot, and cold water from the same tap (depending on model).
- Fine spray prevents splashing and scalding.
- Available in multiple finishes and styles to suit your kitchen.
3) Filtration & Optional Chilled/Sparkling Features
Many Quooker systems include a filter to remove impurities and improve taste. Optional accessories like the CUBE unit can also provide chilled filtered and sparkling water — all from the same tap.
- Filters typically last 6–12 months depending on water quality.
- CUBE adds CO₂ carbonation for sparkling water on demand.
How It Works Step-by-Step
- Cold water flows into the Quooker tank beneath your sink.
- The tank heats and maintains the water at ~110°C under pressure.
- When you activate the tap, boiling water is released instantly — it cools slightly to 100°C as pressure drops.
- The tank refills automatically and reheats within minutes.
Energy Efficiency
Despite staying hot 24/7, Quooker systems are remarkably energy efficient. The vacuum insulation and standby power of around 10 watts make it more economical than repeatedly boiling a full kettle each time you need a cup of tea.
Fun fact: According to Quooker, using one can save up to 100 litres of water per year by reducing kettle overfills and wasted reheats.
Maintenance & Servicing
Like any advanced appliance, regular maintenance keeps your Quooker running perfectly. This includes filter changes, descaling the tank, and occasional checks on the tap mechanism. For reliable, expert care, we recommend booking professional Quooker tap servicing with our experienced engineers.
- Clean the tap nozzle regularly to remove limescale build-up.
- Replace filters and CO₂ cartridges when indicated by the system.
- If you notice reduced flow or noise from the tank, it may need descaling — a quick task for an approved installer.
Installation & Safety
Although a Quooker may look simple, correct installation is key. It involves connecting to your cold and hot water supplies, an electrical outlet, and sometimes additional filter or CUBE units. For safety, it should always be installed by a qualified engineer familiar with pressurised systems.
