Efficiency of a heat pump at low outdoor temperatures

When considering a heat pump, the same question often comes back, "Does a heat pump still work well at low outside temperatures?" This is quite understandable, because in the Netherlands we regularly experience cold nights, frost and days around freezing. In this article, we explain to you exactly how efficiency changes, why you don't need to worry about winter performance, and how we completely unburden you when choosing and installing a heat pump. What do we mean by the efficiency of a heat pump? The efficiency of a heat pump is usually expressed in: COP (Coefficient of Performance) - the efficiency at a given time SCOP (Seasonal COP) - the average annual efficiency over all seasons What exactly does COP say? COP 4 means that for 1 kWh of electricity, you receive about 4 kWh of heat. The higher the COP, the lower your energy bill. What does SCOP say? SCOP looks at: outdoor temperature in all seasons moments of use start-up and defrost cycles Modern air-water heat pumps often achieve a SCOP between 3.5 and 4.5, even in the Netherlands. Why does outside temperature have so much influence? A heat pump extracts heat from the outside air. The lower…
