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.
