Most frequent questions

  • Which Quooker products carry a label? Energy label

    Quooker COMBI tanks are products that deliver hot water as well as boiling water. To achieve this, they are connected to the water supply and also to a heat generator. Because the COMBI tanks comply with these requirements, they come into the category ‘boilers’ and it is mandatory to label them.

    PRO-VAQ tanks only supply boiling water. The EU has not drafted an energy label directive for boiling water tanks and so we cannot provide Quooker PRO-VAQ tanks with a label.

  • 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.

  • How do I register my Quooker system? General

    You can register the Quooker system on our website, using this link.

    If you ever require any assistance with your Quooker just contact our service team via and quote the serial number. This is located on the front of the tank just below the cover.

  • How do I switch my Quooker system on and off? General

    The Q-shaped button on top of the tank is the on/off-switch. Gently press the foot of the Q to switch the Quooker on or off.

    When turning on your Quooker system, a solid red light should appear on the tap and tank. This is to indicate that the water inside the Quooker tank is being warmed up to boiling temperature.

    Wait about 20-25 minutes until the solid red light goes off. The tap should not have any light right now, while the tank will show a slow fading pulse, which we call the heartbeat of the Quooker tank.

    Try to activate the boiling water at your tap. Boiling water should come out.
