Regulation 813 / 2013
Space Heaters
SCOP η s , h
Published regulation 813 / 2013 affects all Heat Pumps ( both air and water cooled ) with a rated heating output below 400 kW ( measured at -10 ° C ambient )
It relates to units used for space heating application that supply hot water and covers two sub-categories based on the leaving water temperature : medium temperature and low temperature .
YORK heat pump units affected by this regulation are classified as Low Temperature because heating outlet fluid temperature can not be supplied at 52 ° C ( measured at -7 ° C ambient ). “ Low-temperature application ” means an application where the heat pump space heater delivers its declared capacity for heating at an indoor heat exchanger outlet temperature of 35 ° C
SCOP- Seasonal Coefficient of Performance
Ecodesign regulation 813 / 2013 introduces a new indicator called Seasonal Coefficient of Performance ( SCOP ), which is the ratio between the annual heating demand and the annual electrical input energy over the entire heating season .
SCOP is calculated using standard EN14825 , which takes the following into account :
• Seasonal efficiency while the compressor is running ( SCOPon )
• Electrical consumption when the compressor is not running : crankcase heater , standby or OFF mode
• Backup heater required to achieve the defined heating design load
SCOP takes into account the energy efficiency achieved at each outdoor temperature of an average climate weighted by the number of BIN hours for each of those temperatures .

* TOL = Operation limit temperature ( maximum -7 ° C ).
** Tbiv = ’ bivalent temperature ’ ( T biv ) means the outdoor temperature declared by the manufacturer for heating at which the declared capacity for heating equals the part load for heating . Maximum T biv is + 2 ° C .

Efficiency requirements set by REGULATION 813 / 2013 – Heat Pumps
Regulation 813 / 2013 sets seasonal energy efficiency in Eta s heat ( η s h ). This value expresses SCOP in terms of primary energy and it makes it possible to compare the energy efficiency of units using different energy sources .

Energy Labelling Regulation 811 / 2013
Heat Pumps with capacities below 70 kW are classified by the European Energy Labelling regulation 811 / 2013 with the objective to inform to the end-user about which is the efficiency level of the heat pump adquired .
