eceee EcoDesign Portal: Lot 11: Circulators in buildings
The measure defines circulator as a glandless impeller pump up to 2500W used primarily for central heating systems. A standalone circulator is a circulator separate from the boiler, glandless means that the circulator has the shaft of the motor directly coupled to the impeller (the motor is also immersed in the pumped medium).

The covered standalone circulators are mainly used for the circulation of water in heater applications in buildings. From 2015 the requirements also cover boiler-integrated circulators that form an integral part of a boiler.
The measure applies an "energy efficiency index" (EEI), which is the ratio between annual consumption of the appliance and a standard consumption of a typical similar model. The regulation will only allow high-efficiency (“intelligent”) circulators, i.e. circulators that can adjust their speed according to their need.
