* The COP figure quoted is calculated as per EN14511.

** In-built immersion heaters will increase running costs and CO2 emissions as they use direct electricity, because of this
Kensa heat pumps do not include them.

*** By increasing the flow temperature from the heat pump the efficiency of the unit will drop and the COP decreases.

Note: Design flow rates are for a ground temperature of 0°C and –4°C and a load temperature of 30°C and 35°C.
