Mitsubishi Ecodan
If you want the safe, widely-supported choice, the Ecodan is it. You'll never struggle to find an installer or parts. Slightly lower flow temperature than the Vaillant, so radiator sizing matters.

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.
