Exceptional Efficiency (A+++ Rating): Across the 4kW, 6kW, and 8kW range, these units achieve an A+++ ErP rating at 35°C flow temperatures. With seasonal efficiency (SCOP) reaching up to 5.0+, the heat pumps can deliver over 5 kWh of heat for every 1 kWh of electricity consumed.

DC Inverter Load Matching: Twin-rotary DC inverter compressors automatically modulate output based on heat demand rather than cycling abruptly on and off, keeping running costs low during mild transitional seasons.

Wide Low-Temperature Range: Designed to maintain strong heating capacity in severe freezing weather down to −25∘C. 

Whisper-Quiet Operation: sound levels drop as low as 35 dB(A) at 3 meters, making them ideal for urban installations 

Integrated All-in-One Monobloc Design: Contains the circulating pump, expansion vessel, and safety components within the outdoor unit, simplifying installation without demanding indoor plant-room space.

Sizing & Property Fit Guidelines

4 kW

Small 1–2 bedroom flats, apartments, or highly insulated new-builds. Ultra-low power draw, highly efficient low-temperature heating.

6 kW

Average 2–3 bedroom terraced/semi-detached UK homes. Excellent balance of low-end modulation and mid-size peak capacity.

8 kW

Larger 3–4 bedroom semi-detached and detached homes. Strong heating delivery even during severe winter cold snaps.
