ANNEX
Amendments to Annexes I and II to Regulation (EC) No 641/2009
Annexes I and II to Regulation (EC) No 641/2009 are amended as follows:
(1) Annex I, point 2, is replaced by the following:
‘2. PRODUCT INFORMATION REQUIREMENTS
1. From 1 January 2013:
(a) the energy efficiency index of standalone circulators calculated in accordance with Annex II, shall be
indicated on the name plate and packaging of the standalone circulator and in the technical documentation
of the standalone circulator as follows: “EEI ≤ 0,[xx]”;
(b) the following information shall be provided on standalone circulators and on circulators integrated in
products: “The benchmark for the most efficient circulators is EEI ≤ 0,20.”;
(c) information concerning disassembly, recycling, or disposal at end-of-life of components and materials, shall
be made available for treatment facilities on standalone circulators and on circulators integrated in
products;
(d) for drinking water circulators, the following information shall be provided on the packaging and in the
documentation: “This circulator is suitable for drinking water only”;
(e) for circulators integrated in products and placed on the market no later than 1 January 2020 as
replacement for identical circulators integrated in products and placed on the market no later than
1 August 2015, the replacement product or its packaging shall clearly indicate the product(s) for which
it is intended.
Manufacturers shall provide information on how to install, use and maintain the circulator in order to
minimise its impact on the environment.
The information listed above shall be visibly displayed on freely accessible websites of the circulator manu
facturer.
2. From 1 August 2015, for circulators integrated in products, the energy efficiency index calculated in
accordance with Annex II, shall be indicated on the name plate of the circulator and in the technical
documentation of the product as follows: “EEI ≤ 0,[xx]”.’;
(2) Annex II, point 2, is replaced by the following:
‘2. METHODOLOGY FOR CALCULATING THE ENERGY EFFICIENCY INDEX
The methodology for calculating the energy efficiency index (EEI) for circulators is as follows:
1. Standalone circulators with pump housing shall be measured as a complete unit;
Standalone circulators without pump housing shall be measured with pump housing identical to the pump
housing in which they are intended to be used;
Circulators integrated in products shall be dismantled from the product and measured with a reference
pump housing;
Circulators without pump housing intended to be integrated in a product shall be measured with a reference
pump housing;
where “reference pump housing” means a pump housing supplied by the manufacturer with inlet and outlet
ports on the same axis and designed to be connected to the pipework of a heating system or secondary
circuit of a cooling distribution system.
2. Where a circulator has more than one setting of head and flow, measure the circulator at the maximum
setting.
“Head” (H) means head (in metres) produced by the circulator at the specified point of operation.
“Flow” (Q) means the volume flow rate of water through the circulator (m 3 /hr).
3. Find the point where Q H is maximum and define the flow and head at this point as: Q 100 % and H 100 % .

4. Calculate the hydraulic power P hyd at this point.
“Hydraulic power” means an expression of the arithmetic product of the flow (Q), Head (H) and a constant.
“P hyd ” means hydraulic power delivered by the circulator to the fluid being pumped at the specified point of
operation (in watts).
5. Calculate the reference power as:
P ref = 1,7 P hyd + 17 (1 – e – 0,3 P hyd ), 1 W ≤ P hyd ≤ 2 500 W
“Reference power” means a relation between hydraulic power and power consumption of a circulator, taking
into account the dependency between circulator efficiency and size.
“P ref ” means the reference power (in watts) of the circulator in a given head and flow.
6. Define the reference control curve as the straight line between the points:
H
(Q

100 %

100 % , H 100 % ) and ( Q 0 % ,
2 )
7. Select a setting of the circulator ensuring that the circulator on the selected curve reaches Q H = max point.
For circulators integrated in products follow the reference control curve by adjusting the system curve and
speed of the circulator.
“System curve” means a relationship between flow and head (H = f(Q)) resulting from friction in the heating
system or cooling distribution system, as presented in the following graph:

8. Measure P 1 and H at the flows:
Q 100 % , 0,75 Q 100 % , 0,5 Q 100 % , 0,25 Q 100 %
“P 1 ” means the electrical power (in watts) consumed by the circulator at the specified point of operation.
9. Calculate P L as follows:

P L = P 1,meas , if H meas > H ref
Where H ref is the head on the reference control curve at the different flows.

a certain type have an EEI ≤ 0,20.’.
