Most frequent questions


  • Why does the Quooker COMBI carry an A label? Energy label

    In order to verify the calculations conducted, a practical test is conducted on the energy efficiency of the Quooker COMBI tanks. The report with the detailed results from this test, conducted in accordance with the standard ‘NEN-EN 50440 Efficiency of domestic electrical storage water heaters and testing methods’ can be requested from Quooker.

    Quooker COMBI tanks are products that delivery hot water as well as boiling water. Because the COMBI tanks comply with these requirements, they fall into the category "boilers" and it is mandatory to label them. 

    The energy label an appliance carries depends on its energy efficiency. Due to the energy loss in the generation of energy in power stations in 2015, an electrical appliance can achieve a maximum energy efficient of 40%. The energy loss (non-beneficial use of the energy) that an appliance suffers, in Quooker’s case the standby power consumption, reduces this efficiency still further. Because a Quooker is fitted with high-vacuum insulation cladding, the energy loss is only 10 watts. Due to this, the total energy efficiency for the Quooker tanks is 36% and this results in an A label for the Quooker COMBI tank in the XXS category.

  • I have noticed Quooker delivers water at 100°C. Is this important? General

    Yes, this is of fundamental importance. Quooker is the world’s only true 100°C boiling water tap and as a consequence it is the only tap on the market that truly allows you to be rid of the energy-greedy kettle. (Remember if the water temperature is not 100°C at the point of delivery, you will not be able to replace your kettle).

  • Does the water boil all day in the tank? General

    The stainless steel tank with revolutionary patented vacuum insulation and thermos technology holds water under pressure so it does not boil; however, it has all the properties and benefits of fresh boiling water and is held under pressure at 110°C.

  • My Quooker is not producing any boiling water. Troubleshooting

    Check the lights on the tap and tank. If the light on the tap/tank is flashing, please refer to the corresponding question in our FAQs.

    If the lights are off, please press the Q-shaped button on top of the tank to switch the Quooker back on. If the lights still do not come on, unplug the Quooker and check the electrical supply socket by plugging in another appliance. If the socket is working, please change the fuse in the Quooker's plug, then plug it back in again and try pressing the Q-shaped button on top of the tank again.

    If this does not resolve the issue, please contact our service department via our request form or on 0207 9233355 (select option 3 for Service). Please have your Quooker's serial number ready – it is located at the side of the tank near the top.
