KEYMARK certification


KEYMARK is a voluntary and independent European certification mark (ISO type 5) for heat pumps, combination heaters with heat pumps and service water heat pumps.


Certification for heat pumps

European, voluntary and independent

KEYMARK is based on independent testing performed by a renowned test laboratory and demonstrates compliance with the product requirements according to regulations. The units must also fulfil the efficiency and noise emission requirements for heat pumps as stated in the Ecodesign Directive. Product manufacturing is also certified. Mitsubishi Electric is currently working through the certification process with the Ecodan heat pump systems. The Zubadan systems featuring 14 and 23 kW are already KEYMARK-certified.
