NULITE Flamingo Series is a monobloc 3-in-1 air-source DC inverter heat pump for space heating, cooling, and domestic hot water. The range includes six R32 models with modulating heating output from 2.8 to 40 kW and an ambient operating range from −25 to +43 °C.
Construction and controls
The system uses a Mitsubishi twin-rotary inverter compressor, full-DC fan motor, plate heat exchanger, and integrated hydronic controls. The table lists a built-in inverter circulation pump and 5-litre expansion vessel for the first four sizes; the larger models use an 8-litre vessel, while pump scope is confirmed at order stage. The controller supports Wi-Fi, RS485, a multilingual interface, operating-mode selection, and three-way valve control.
Key benefits
- Five operating combinations: heating, cooling, DHW, heating + DHW, and cooling + DHW.
- Water temperature up to 55 °C for DHW and 45 °C for space heating under the manufacturer's rated data.
- Low-ambient operation down to −25 °C and IPX4 enclosure protection.
- Integrated 3 kW auxiliary electric heater.
- Noise level from ≤49 to ≤59 dB(A), depending on model.
Applications
- Private homes, townhouses, and low-rise residential buildings.
- Hotels, serviced apartments, and facilities with continuous DHW demand.
- Offices, shops, cafés, and light-commercial buildings.
- Systems with underfloor heating, fan coils, buffer tanks, and indirect DHW cylinders.
- Hybrid systems using solar thermal or an auxiliary heat source.
System integration
The heat pump can be integrated with a buffer tank, fan coils, underfloor heating, and a DHW cylinder. Engineering must determine building heat loss, design ambient condition, supply-water temperature, peak hot-water demand, and electrical capacity. Rated water flow is 1.6–6.0 m³/h; connections are DN25 for the first four models and DN40 for the two larger sizes.
Specifications refer to the R32 models in the attached brochure table. Actual output and efficiency vary with ambient and water temperatures; electrical version and scope of supply are confirmed during selection.
