9000 BTU Mini Split Air Conditioner and Heater A++ Energy Efficient Split AC Cools Up to 42㎡

The Costway 9000 BTU split air conditioner is an A++ inverter mini split that both cools and heats spaces up to 42m², making it a true year-round unit for a bedroom, home office or studio. Its inverter compressor and SEER 6.1 / SCOP 5.1 ratings are what set a fixed split apart from a portable: it modulates output rather than cycling on and off, so it holds temperature smoothly and quietly. A silence function brings the minimum noise down to 19dB — comfortably quiet enough for a bedroom — while 4D swing, 5 fan speeds and a 24-hour timer with an 8m remote handle everyday comfort. Cooling and heating are both rated at 9,000 BTU (2600W / 2610W) with 21.6L/day dehumidification and 500m³/h airflow. On a 1600W power input it draws about 1.6kW, costing roughly 42p an hour at around 26p/kWh at full output, though the inverter typically runs well below this once the room is at temperature. It uses R32 refrigerant and offers 7 modes plus child lock, self-clean and auto defrost. Note the honest install reality: as a split system with an outdoor condenser, it requires F-Gas-certified installation under UK rules — it is not a plug-in unit.
