R32 refrigerant and sustainability features: this inverter pool heater uses R32 refrigerant and efficient air-water heat transfer to temperature pool water more energy-saving than many classic electric heating solutions. Thanks to proven sustainability features, it is a suitable choice for pool owners who value performance, efficiency and a more conscious product decision.
Quiet outdoor operation with DN50 connection: with approx. 42-53 dB(A), the heat pump is pleasantly restrained for use in the garden. DN50 water connections, IPX4 protection, PVC pipe adapter, condensation drain hose and rubber vibration damper support clean integration into private pool facilities. Note: The initial heating phase can take up to 48 hours depending on the pool size, outdoor temperature and pool cover; a pool cover is especially recommended at night.
Inverter technology with COP up to 13.0: the pool heat pump uses the ambient air to heat the pool water and intelligently adjusts its performance to the actual heating requirements. When heated, it works more powerfully, while maintaining the target temperature, it automatically reduces power. At air 26 °C / water 28 °C, it reaches up to 12 kW of heat output and a COP of up to 13.0 - ideal for users who want to combine strong power and more conscious power consumption.
Heating, cooling and comfortable control: whether cool morning hours, changeable weather or hot summer days: the pool heat pump supports heating, cooling, auto, smart and turbo mode. Temperature, timer and operating modes can be easily adjusted via the digital control panel and WiFi function, so that the water temperature can be adjusted more flexibly to weather, season and personal bathing habits.
For medium-sized pools up to approx. 45,000 litres: This 12 kW inverter pool heat pump is suitable for medium-sized garden pools, above-ground pools and steel wall pools up to approx. 45,000 litres. Compared to small mini heat pumps, it offers more power reserve to temperature larger amounts of water more comfortably and extend the bathing season in Germany more comfortably.
