Main highlights

*5* - Robust construction and commercial intelligence: The robust steel housing and high-quality enamel inner tank ensure a long service life even during intensive continuous operation. WiFi remote control and compatibility with solar systems or gas heating systems allow flexible integration into existing energy concepts. The wide working temperature range from -7°C to 45°C makes it a year-round all-in-one solution for villas, commercial properties, hotel businesses and large households.
*4* - Stable and low-vibration continuous operation: Thanks to the floor-standing construction and optimised vibration damping, the system works particularly quietly and stably even under full load. The highly efficient DC fan and multi-layer sound insulation materials reduce operating noise to a minimum - ideal for installation in technical rooms, commercial spaces or separate utility areas.
*3* Dual Power Quick Heating for Peak Loads: The innovative dual power mode combines the air source heat pump with a powerful electric auxiliary heater. In case of high simultaneous hot water demand – for example in hotels, holiday apartments or large residential buildings – the entire storage unit is heated up in no time. Guaranteed no waiting times even at full load operation.
*2* ️ Intelligent defrosting for year-round stability: The precisely controlled defrosting system with electronic expansion valve and 4-way valve ensures efficient and complete defrosting even in severe frost. Minimises performance losses and allows uninterrupted hot water supply - perfect for use in cool basements, technical centres or unheated commercial premises.
*1* - Environmentally friendly high performance for large hot water requirements: Equipped with natural R290 refrigerant matched high-performance compressors for efficient hot water heating up to 75°C and saves up to 80% energy costs compared to conventional electric heaters - ideal for economical continuous operation in commercial and large-volume applications.

Variable use: do you use salt water disinfection? No problem! Thanks to titanium heat exchanger, salt values of up to 5 per thousand are permanently no problem. The different modes allow you to use it according to personal taste. At full load, it is attempted to retrieve the maximum power. In silent mode, the volume is particularly low and the efficiency of energy conversion is significantly increased. This mode is suitable for maintaining target temperatures automatically and at a low cost.
Strong: with 13 kW heat output at max. 1.85 kW power consumption in continuous operation, you can effectively heat large pools up to a maximum of 58,500 litres. Use a solar film for thermal insulation so that the energy supplied stays in the pool as much as possible. The additional use of floor insulation in the form of foam mats or styrodur increases the effectiveness of your pool setup.
Quiet: Our Sirius inverter series works with variable speeds and a particularly effective roller fan. The volume level is significantly lower even at full load than most similarly strong "on/off" heat pumps. In silent mode, the volume drops again - this mode is also particularly energy efficient.
Protects your wallet: depending on the circumstances (outdoor temperature, water temperature, operating mode), a COP value of up to 16 can be achieved. Then you can generate up to 16 watts of heat energy from one watt of electricity. Even under not ideal circumstances, COP values from 7 (full load operation) to 11 (partial load operation) are often achieved in practice, which makes classic on/off models look old. Thanks to the superior efficiency, you can heat your pool at manageable electricity costs.
Practical tips: place the heat pump in a sunny place so that it can draw the warmer air, which benefits the heating efficiency. If you want to heat particularly frequently and for a long time in the maximum efficient partial load mode, you prefer to size the heat pump "too strong" if in doubt. For particularly fast heating and significant extension of the pool season, approx. one kilowatt of peak power.
Connection: They are particularly flexible with our Sirius heat pumps. Whether 32 mm or 38 mm hoses: thanks to the included adapter, a particularly light and uncomplicated connection is made. If you are using a 50 mm piping, you can simply use our 50 mm connector which is also included. Our highlight: all Sirius models can be connected to normal Schuko sockets, which saves money and time - however, we require well-secured electronics
