(1) Value obtained with an air temperature of 7°C when heating from 10°C to 54°C.
(2) Value obtained with an air temperature of 15°C when heating from 10°C to 54°C.
(3) Value obtained with an air temperature of 7°C and a water inlet temperature of 10°C according to EN16147 based on LCIE Specifica­
tions No. 103-15/B: 2011.
(4) Value obtained with an air temperature of 15°C and a water inlet temperature of 10°C according to EN16147 based on LCIE Specifica­
tions No. 103-15/B: 2011.
(5) Absorbed electrical power at stabilised rate.
(6) Quantity of refrigerant calculated in tonnes of CO
2
equivalent.
(7) Measured at a distance of 2 metres.
Note
The values in tonnes of CO
2
equivalent are calculated using the
following formula: quantity (in kg) of refrigerant fluid x GWP /
1000.
GWP = Global Warming Potential. The GWP of R-134a is 1430.
Note
R-134a refrigerant is contained in equipment that has been her­
metically sealed.
