LG Artcool Mirror

The Artcool Mirror leads on looks with its reflective glass fascia and adds LG's UVnano UV-LED to keep the fan clean. Efficiency is only mid-table (A++ cooling, A+ heating) so as a heat pump it is competent rather than class-leading, but it heats and cools quietly with a 19 dB(A) sleep mode. Best chosen when design and smart features matter more than raw running costs.

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.
