Daikin Altherma 3
Pick the Altherma 3 if your home needs high flow temperatures — it's happiest where others struggle. Slightly lower SCOP and uses R32 rather than a natural refrigerant.

Our top pick for most homes. The R290 refrigerant hits high flow temperatures without wrecking efficiency, so it works in older properties that haven't had radiators upsized. Long warranty seals it.
