The Worcester Bosch Climate CL3000i 7.0 kW single split system (indoor unit CL3000iU W 70 E + outdoor unit CL3000i 70 E) is the most powerful model in the CL3000i range, delivering 7.0 kW of cooling and 7.3 kW of heating for large spaces up to approximately 60–70 m². With a SEER of 6.4 (A++ cooling) and SCOP of 4.0 (A+ heating), it provides cost-effective, energy-efficient climate control for large living rooms, open-plan apartments, commercial reception areas and small offices. The powerful indoor unit (1082 × 234 × 337 mm) delivers up to 1,090 m³/h of airflow on high speed, while Silent Mode reduces indoor noise to just 21 dB(A). The same i-Clean self-sanitising evaporator, double filtration and optional Wi-Fi control via the Bosch HomeCom Easy app are all included.

Key Features & Benefits
DC Inverter Technology — Efficient & Responsive
Variable-speed DC inverter compressor continuously modulates output to match the exact heating or cooling load — eliminating on/off cycling, delivering faster temperature recovery and tighter control, and cutting electricity consumption versus fixed-speed units.
A++ Cooling / A+ Heating ErP Rating
Seasonal efficiency ratings of A++ (cooling) and A+ heating — average climate, rising to A+++ in warmer conditions. These SEER and SCOP values are measured under EN14825 seasonal test conditions, giving a realistic picture of real-world running costs.
Silent Mode — Ultra-Quiet Operation
A dedicated Silent Mode reduces both indoor and outdoor unit noise to their minimum levels. The indoor unit drops to 21 dB(A) — quieter than a whisper — making the system genuinely suitable for bedrooms, nurseries and noise-sensitive environments.
i-Clean Self-Sanitising Evaporator
After each cycle, the i-Clean function heats the indoor evaporator to 56°C, destroying up to 99% of bacteria and mould spores that would otherwise accumulate on the damp heat exchanger. Only clean, healthy air is delivered into the room.
Double Filtration — Odour & VOC Removal
A dual-stage washable filter removes airborne particulates and neutralises odours, harmful gases and volatile organic compounds (VOCs). The reusable filter requires no replacement — simply rinse and refit at each service.
Follow Me — Temperature Sensed at Your Location
The Follow Me feature uses the temperature sensor in the remote controller rather than the indoor unit, so the system responds to the actual temperature where you are in the room — especially useful in large or open-plan spaces.
Heating Down to -15°C Outdoor Temperature
The CL3000i maintains effective heating performance with an outdoor ambient temperature range of -15°C to +24°C, ensuring reliable warmth throughout UK winters without the need for supplementary electric resistance heating.
Wi-Fi Control via Bosch HomeCom Easy App
With the optional Connect Key G10 CL-1 accessory (sold separately), the unit connects to the Bosch HomeCom Easy app for full remote control — scheduling, temperature adjustment, mode changes and energy monitoring from any smartphone or tablet.
Corrosion-Resistant Golden-Fin Outdoor Unit
The outdoor heat exchanger features a golden-fin anti-corrosion coating, providing lasting protection against salt air and atmospheric pollutants — ideal for coastal and urban UK installations.
R32 Low-GWP Refrigerant
Charged with R32 refrigerant (GWP 675) — approximately one third of the environmental impact of R410A — aligning with the UK and EU F-Gas regulation trajectory towards lower-impact refrigerants.
