What is good

  • Four modes including heating, so it works year-round
  • Smart app plus Alexa and Google Home voice control
  • Class A efficiency with eco R290 refrigerant
  • Reasonably quiet for a 12K unit at around 54 dB

What to watch

  • Single-hose, so cooling efficiency falls in very hot rooms
  • Heavy at nearly 30 kg
  • Premium pricing, and frequently out of stock
  • Heating is electric-resistance assisted, not a full heat pump

Installation & the rules that apply

This is a portable monobloc. The most regulation-light option by far. No F-gas certified installer is needed because you never break into the refrigerant circuit, no planning permission or permit is triggered since nothing is fixed to the building, and a landlord usually cannot refuse it as there are no permanent alterations. The main constraints are the tenancy or building rules on window-kit appearance and noise nuisance to neighbours.
