Received an e-mail back from Polar Air. Our apartment is a duplex 2 bed Tilo, he recommends to use a 24000btu fujitsu general inverter ducted system also a 9000 btu single split fujitsu general unit at a cost of 2750.00 euros inc iva and installation. He says it can be obtained in the non inverter system at 2550.00 euros, but the inverter system would be cheaper to run.
