With the Heat pump Silent 21,2, pleasantly tempered pool water is available with maximum energy efficiency and whisper-quiet operation. Thanks to modern inverter technology, the heat pump reliably heats or cools and operates with particularly low power consumption. The 2026 generation impresses with numerous detail improvements that further enhance ease of use and efficiency. The touch display enables intuitive control, while the integrated LED status indicator clearly shows the operating status at all times (blue = operation, green = target temperature reached, red = fault). The heat pump can be flexibly integrated into existing pool control systems as well as smart home or photovoltaic systems via the external potential-free control input (two-wire) and the switched 220 V terminal.
With a heating capacity of 21.200 W, this model is suitable for pools with a water volume of up to 80.000 l. The app control for iOS and Android allows convenient operation. With dimensions of 111 x 46 x 75,50 cm (D 50 connections), the heat pump is suitable for saltwater use and operates with the environmentally friendly refrigerant R290. A low CO2 equivalent of 0,00285 t as well as quiet operation (34 dB(A)) ensure a high level of comfort in everyday use. Individual operating modes such as POWER, SMART, SILENT and AUTOMATIC allow optimal adjustment to current demand. At the same time, they help reduce operating costs. The heat pump is easy to integrate and, with a maximum input power of 3.800 W, offers a powerful solution for larger pools.
