Grant UK has recently introduced the Aerona HE range. It offers bigger single phase models, higher outputs and CoPs at lower air temperatures with even quieter noise levels, whilst maintaining the tried and tested features of the existing Aerona range. The Aerona HE range offers units from 6.5kW u-p to 21.5kW and provides higher CoPs sustainable at lower temperatures. MCS approved, these units use R410a refrigerant which allows them to operate at lower ambient temperatures.
