COP (Coefficient of Performance) indicates how efficiently a heat‑pump water‑heater converts electricity into heat output. A higher COP means lower energy consumption for hot‑water production.
Under standard test conditions (air temperature 20 °C), a decent domestic hot‑water heat pump should reach a COP of at least 3.0. Premium‑grade models can achieve COP 3.5‑4.2. It is worth noting that COP drops as ambient temperature falls. At low temperatures around 7 °C, a reliable unit should still maintain COP above 2.6.
COP figures vary according to test standards, so always check which certification standard the data follows. For Kolant domestic hot‑water heat pumps, optimized compressor systems deliver stable high‑COP performance across seasonal temperature changes. The EVI equipped versions preserve acceptable heating efficiency even in cold climates, avoiding sharp efficiency decline in winter.
Kolant’s heat pump water heater’s cop is 2.92~4.00, meet the requirements of the customer.
