Performance diagrams

14.7.1. COP diagram
The heat output and the resulting COP value have
been measured in compliance with EN 16147 at a
water inlet temperature of 10 °C.
The COP values depending on the air intake tempera-
ture are shown in the following diagram.

14.7.2. Heating-up time

The diagram below shows the heating-up time at dif-
ferent air intake temperatures for full loading of the
cylinder with 45 °C or 60 °C domestic hot water in
pure heat pump operation (without additional electric
heating).
