Panasonic Etherea Z

The Etherea Z is Panasonic's premium wall split, pairing A+++ ratings in both modes with the nanoe X air purifier that runs even when you are not cooling. Its high SCOP makes it a strong air-to-air heat pump, comfortably heating a room through a UK winter at low cost. A refined, quiet and well-rounded alternative to the Daikin Perfera.

Samsung WindFree Avant

The WindFree Avant's party trick is 'still air' cooling through thousands of micro-holes, avoiding the cold draught most splits create, and the WindFree mode runs near-silently. The latest generation lifts efficiency to A+++ cooling, and with a SCOP near 4.8 it makes a solid air-to-air heat pump for winter warmth. Built-in SmartThings and self-cleaning round out a well-featured package.
