ᵻ Units are currently being ErP tested and will be available when complete.
^The 45kW Plantroom produces above 50kW at a ground temperature of 0°C and load temperature of 35°C.
+ Cooling only units are not MCS approved.
* The COP figure quoted excludes the water pump electrical input and is calculated according to 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.
**** The starting currents are per phase. For full details on how the starting currents are calculated please contact Kensa.
*********The SCOP figure quoted is calculated as per EN14825.
Note i): Design flowrates and pressure drops are based on a ground temperature of 0°C and –4°C and a load temperature of 30°C and 35°C.
Note ii): The P500X unit is classed as a Low Temperature Space Heater as per the ErP regulations.
