Energy label

Most domestic appliances, light bulbs and cars offered for sale or rent in the EU must clearly display an EU Energy Label showing the product’s energy efficiency.

The energy efficiency of an appliance is rated in terms of a set of energy efficiency classes from A to G, with A being the most energy efficient and G the least efficient. In an attempt to keep up with advances in energy efficiency, A+ and A++ grades have been introduced for refrigeration appliances.

The labels thus improve the information available to consumers when evaluating various models.

Centrifugal pumps are also covered by an efficiency index that has been developed on behalf of a number of major pump manufacturers, including Grundfos. The manufacturers have collaborated to produce a reference index for a standard pump with an average load profile.

The index expresses the power consumption of the pump in relation to a common reference pump curve. The index can be interpreted as an expression of how much energy a specific pump uses in relation to an average pump in 2003 when the index was originally established.
