* 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.
**** Kensa Evo heat pumps incorporate smart starts as standard to limit the starting current of the compressors. For full details on how the starting currents are calculated please contact Kensa.
****The SCOP figure quoted is calculated as per EN14825.
Note: Design flowrates are for a ground temperature of 0 and –3oC and a load temperature of 30oC and 35oC
