Octopus Cosy 6
The value disruptor. Octopus's bundled install plus the grant can make a heat pump astonishingly cheap, and the Cosy 6 itself is a capable R290 unit. Best if you're an Octopus customer.

An underrated option: R290, high flow temperature and a SCOP up to 4.0 at a competitive price. Installer familiarity is the main thing to check locally.
