air-to-water model, inverter, reverse cooling mode, 1-6 kW heating output, 1.5-5.5 kW cooling output
Air source heat pumps draw energy from the ambient air even when the outdoor temperature drops to -22°C. The energy gained at a low temperature is then “pumped“ to a higher temperature and transferred into heating water. Electric energy is consumed just to run a compressor and fan of the heat pump. This makes about one third of the energy supplied by the heat pump, the rest is drawn from the ambient air. Reliability and excellent parameters of CTC heat pumps are proved by many thousands annual installations in the harsh Scandinavian climate.
