The Rotenso WINDMI WIM100X1 is a single-phase monobloc heat pump with a heating capacity of 10.0 kW (A7/W35). The unit boasts exceptionally high energy efficiency, achieving an A++ rating for a flow temperature of 35°C and an A++ rating for a flow temperature of 55°C. Its SCOP is 4.98 (for a supply temperature of 35°C), making it extremely efficient.
TEMPERATURE RANGE
The water outlet temperature in heating mode ranges from 20°C to 62°C, while in hot water mode it ranges from 40°C to 62°C.
ADAPTATION TO EXTREME CONDITIONS
The heat pump is designed for operation in harsh weather conditions, even at outdoor temperatures as low as -25°C. To ensure reliable operation at sub-zero temperatures, the unit is equipped with a drip tray heater that prevents condensate from freezing and the outdoor unit from icing up. This eliminates the risk of damage to the fan and heat exchanger.
CRANKCASE HEATING OF THE COMPRESSOR
The Rotenso WINDMI WIM100X1 heat pump is equipped with a compressor crankcase heater that warms the compressor oil at temperatures below 0°C, thus ensuring trouble-free start-up even in adverse weather conditions. Thanks to this feature, the heat pump operates flawlessly and the compressor's service life is extended.
ADDITIONAL HEATER
The heat pump is equipped with a 3 kW auxiliary heater, which is useful in emergency situations or at very low temperatures. The heaters support the economical operation of the unit while simultaneously ensuring the longevity and reliability of the heat pump.
EASY INSTALLATION AND OPERATION
The Rotenso WINDMI is easy to install, maintain, and use. Thanks to its two-door housing design, all pump components are easily and quickly accessible. The pump's quiet operation is achieved through the use of a single-fan design and a dual-rotor DC compressor.
REMOTE CONTROL
The Rotenso WINDMI heat pump can be controlled via a mobile app or a modern wired controller to make it easier to use.
WARRANTY AND SERVICE

Important NOTE!
The installation and commissioning of the equipment must be carried out exclusively by qualified personnel. In the event of a complaint, proof of proper installation by qualified specialists (certificate of professional qualification and special qualifications) must be provided. If no such proof is provided, all warranties and guarantees will be void.
Technical specifications subject to change without notice. Errors and omissions excepted. Subject to prior sale. Image may differ from actual product.
Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher GWP. A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming, proportional to the refrigerant's GWP value, than 1 kg of CO2, over a period of one hundred years. Do not attempt any work on the refrigeration circuit or disassemble the unit – always consult qualified personnel.
