Grant Aerona³ heat pumps awarded KEYMARK approval 

The Aerona³ air source heat pump range from Grant UK has been approved by CEN KEYMARK, an independent European certification mark for all heat pumps, combination heat pumps and hot water heaters.  

All of Grant’s Aerona³ heat pumps, available in 6kW, 10kW, 13kW and 17kW models, are now KEYMARK approved, which is an accreditation that accompanies the range’s existing MCS approvals. The heat pump KEYMARK scheme is a voluntary, independent certification mark which is recognised throughout the European market.  

Products must demonstrate compliance to be accredited 

Owned by the European Committee for Standardisation, the heat pump KEYMARK scheme sets out a series of rules and efficiency requirements that products must demonstrate compliance with during independent, third-party testing.  

The Grant Aerona³ air source heat pump range, which uses R32 refrigerant, boasts excellent SCOPs and all the models have an ErP rating of A+++. In addition to their MCS and KEYMARK accreditations, Grant heat pumps have also been recognised for their quiet operation with both the 13kW and 17kW units having the Quiet Mark. 

“We are very pleased that our Aerona³ range has achieved KEYMARK certification,” said Neil Sawers, Grant UK’s commercial technical manager.  

“The CEN Heat Pump KEYMARK is a certification scheme that supports the quality of heat pumps in the European market and the KEYMARK logo helps customers find products that fulfil core requirements and efficiency standards as set out by Ecodesign.”
