Main highlights

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
