A very energy-efficient idea

What sounds like pure luxury – having boiling water available always – is also a very energy-efficient idea. The Quooker boiler is one of the most sustainable investments for the kitchen and has now been awarded Energy label A.

From September 2015 onwards, a European regulation will apply to kitchen boilers. In the category for smaller electronic water heaters with a storage tank for kitchens, the Quooker COMBI is the highest-scoring kitchen boiler with a boiling water function and has therefore been awarded Energy label A.

Energy label A for Quooker COMBI

The Quooker COMBI tank is stored in the kitchen cupboard and dispenses boiling water at 100°C as well as hot water at between 40°C and 60°C. This is the world's first ‘boiler’ with high-vacuum insulation and is therefore the most energy-efficient way of supplying hot water supply to your kitchen!

The Quooker COMBI is only connected to the cold water pipe. By mixing the cold water with boiling water, you have an immediate 15-litre supply of hot water at 60°C.

The PRO3 tank only dispenses boiling water. The EU has no energy label guideline for boiling-water tanks. However, these tanks are equally economical.

Frequently asked questions

Has anything in the COMBI tank been changed to gain the A label?

At Quooker, sustainability has been high on our requirements list right from the first product concept. Our tanks are manufactured with vacuum insulation that ensures that the energy loss is minimal. This has always been the case, and will remain so in the future. The introduction of the label qualification by the EU confirms that Quooker boilers are sustainable.

The energy label that an appliance carries is determined by its energy efficiency. Due to energy loss in the generation of energy in power stations in 2015, an electrical appliance can achieve a maximum energy efficiency of 40%. The loss (non-beneficial use of the energy) that an appliance suffers, in Quooker's case the standby power consumption, reduces this efficiency further still. 

Because a Quooker is fitted with high-vacuum insulation cladding, the energy loss, is only 10 watts. Due to this, the total ernergy efficiency for the Quoker tanks is 36% and this results in an A label for the Quooker COMBI tanks in the XXS category.

What is the annual energy consumption of a Quooker COMBI?

A Quooker COMBI consumes 511 kWh per year if warm water is used in accordance with the usage pattern defined in the regulations.

How many dB does a Quooker emit?

A Quooker clicks when it turns on and off, but otherwise is silent. The heating element heats the water to 110°C and the tank stores it. The water supply pressure ensures that the water does not ‘bubble’ and therefore the appliance is silent.

Why does the Quooker COMBI carry an A 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.
