ENER Lot 1 - Space Heaters (Heat Pumps)
Published regulation 813/2013 affects all Heat Pumps (both air and water cooled) with a rated heating output below 400kW
(measured at -10°C ambient).
The heat pumps affected by this regulation are classified as Low Temperature if heating outlet fluid temperature can not be
supplied at 52°C (measured at -7°C ambient).
A new KPI
Ecodesign regulation 813/2013 introduces a new Key Performance Indicator (KPI) for seasonal primary energy efficiency
(η s,h ), that allows product efficiency comparison with different energy sources.
ƞ s,h (%) =1/CC x SCOP -∑ F i
SCOP – Seasonal Coefficient of Performance CC – Conversion Coefficient
Ratio between the annual heating demand and the annual
electrical input energy over the entire heating season. European average coefficient that represents the amount of
primary energy required to obtain electricity.
SCOP is calculated using standard EN14825, which takes
the following into account: CC is defined by the regulation with a constant value of 2,5.
• Seasonal efficiency while the compressor is running
(SCOPon) ∑ F i – Correction Factors
• Electrical consumption when the compressor is not
running: crankcase heater, standby or OFF mode
Air source heat pumps
∑ F i = 3%
• Backup heater required to achieve the defined heating
design load Water source heat pumps
A better Indicator Easy to Compare
η s,h and SCOP are better indicators than full load COP for
heating efficiency, as they take into account a representative
set of operating hours and real world conditions. η s,h is the Seasonal PRIMARY Energy Efficiency value and is
used to compare heating products using different energy
sources.
∑ F i = 8%
