Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What we like about Bosch Climate 3000i Set 26 WE

  • Excellent cooling and heating performance across different seasons
  • Highly energy-efficient with an A++ rating for cooling and A+ for heating
  • Extremely quiet operation, especially when using the 20dB Silent/Sleep mode
  • Effective air purification and dust filtering, which helps users with allergies or hay fever
  • Useful smart features like the 'Follow Me' temperature tracking and 'i-Clean' self-cleaning mode
  • Great value for money from a well-known, reliable brand

What we don't like about Bosch Climate 3000i Set 26 WE

  • Wi-Fi connectivity and remote app control require a separate hardware module (Connect Key G10 CL-1) that is not included as standard
  • Heating output and efficiency can drop noticeably in extreme winter temperatures below 0°C due to automatic defrost cycles
  • The 2.6 kW capacity (9000 BTU) is only suitable for smaller spaces and can struggle in larger rooms or poorly insulated areas
  • Professional installation by a certified F-Gas engineer is mandatory, which increases the total initial cost

Verdict

The Bosch Climate 3000i Set 26 WE is a reversible single-split inverter air conditioner utilizing eco-friendly R32 refrigerant, offering a 2.6 kW (9,000 BTU) cooling capacity and a 2.9 kW heating capacity suitable for rooms up to 25 square meters. It achieves strong seasonal energy efficiency with an ErP rating of A++ for cooling (SEER 7.4) and A+ for heating (SCOP 4.1), operating across a wide ambient temperature range from -15°C up to +50°C. Main advantages include a high-density air-purifying filter that eliminates up to 95% of dust and pollen, an 'i-Clean' self-cleaning mode that heats the evaporator to 56°C to destroy 99% of bacteria, an ultra-quiet silent mode lowering outdoor unit emission down to 20 dB(A), and an energy-saving Eco/Gear mode. However, a major drawback is that Wi-Fi connectivity and smartphone app control are not built-in, requiring the separate purchase of an optional G10 CL-1 gateway accessory, and the remote timer lacks advanced, multi-day scheduling functions.
