The quality of a heat pump depends on the ratio between the energy supplied and the energy obtained. The seasonal coefficient of performance (SCOP) represents the ratio between cost and return. The annual performance factor is therefore the best measure to evaluate the quality of a heat pump. Values between 3.5 and 4 are considered good with regard to the annual performance factor. This system has a SCOP value of 4.6!
Interior and exterior unit with durable Gold Fin lotus effect, non-stick coating - always shiny and clean with high performance for many years! The Gold Fin coating also prevents the settlement of bacteria and fungi on the slats. This keeps the air healthy and fresh and prevents bad odours.

Extremely powerful, yet very quiet and economical. DC full inverter system, original Dimstal, Golden Fin, lotus effect, intelligent, energy- saving, antibacterial and durable. Works on 230 V household voltage. Energy efficiency class: Cooling/heating = A++/A++ DC full inverter: the operating speed of the inverter compressor motor is continuously and steplessly controlled according to the system capacity requested.
Complete carefree set: Smart eco indoor and outdoor unit with Gold-Fin technology - pre-filled with modern refrigerant. Includes 3 m copper cables and wall bracket with mounting material. Includes remote control with illuminated LCD display, sealant for wall passage, insulation tape, drainage hose, power connection cable between the interior unit and the external unit, and an instruction manual in German/English.
Although GWP ≤ 750 is only required from 2025 onwards, our system is already pre-filled with state-of-the-art R32. Advantages: The potential cooling capacity of R32 is 1.6 times higher. R32, in particular, has lower pressure losses than R410A at the same output. This means that the performance figures for the system can be increased significantly while the heat exchanger surfaces remain the same. These are all very good reasons for us to take the next step in innovation.
