1.5 kWMHI Ciara 1.5kW Split System
The 1.5kW MHI Ciara Split (model DXK05ZTLA-W) is sized for very small rooms and studies. As a guide it suits a typical insulated room of roughly 10 to 12m²; sun exposure and ceiling height move that band. It is the smallest capacity in the MHI Ciara Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 2kW.
The MHI Ciara 1.5kW uses 172 kWh per year for cooling and 243 kWh per year for heating, based on official GEMS testing for Sydney's climate zone. These figures let you calculate running costs using your current electricity rate. The system achieves a cooling efficiency rating of 4.03 AEER and heating efficiency of 4.53 ACOP.
For Sydney's climate, the MHI Ciara carries a 1.5-star cooling rating and 3-star heating rating under the government's zoned energy label. The unit uses R32 refrigerant. Your actual energy consumption will depend on how often you run the system and your temperature settings.
