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.

  • 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.

  • I have noticed you have a PRO3-VAQ and a PRO7-VAQ, how do I decide which is most suitable? General

    80% of Quooker sales are of the PRO3-VAQ model. This has a capacity of 3 litres and will provide 3 litres on demand; 15 litres in the first hour of a day and then 12 litres thereafter. The PRO7-VAQ will provide 7 litres on demand; 35 litres in the first hour of a day and then 28 litres thereafter.
