Grant Aerona3

A dependable, fairly priced choice that UK installers know well. Efficiency trails the R290 leaders but it's a solid all-rounder backed by good support.

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.
