Fujitsu ASYG12KMCF

Fujitsu's KMCF is a no-nonsense, well-built wall split that undercuts the premium brands while keeping A++ cooling and a slim 222 mm-deep indoor unit. Its SCOP of 4.4 makes it a capable air-to-air heat pump for everyday room heating, if not the most efficient here. The KMCF adds built-in Wi-Fi over the base KMCC, making it the version to buy.

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.
