        "note": "The Carnot COP is the unbeatable ceiling set only by the absolute temperatures: heating = Th ÷ (Th − Tc), cooling = Tc ÷ (Th − Tc), with T in kelvin (and heating COP always equals cooling COP + 1). The smaller the temperature lift, the higher the ceiling — which is why ground-source and low-temperature underfloor systems outperform air-source on a cold day.",
