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.
