Toshiba Seiya Classic Series 10.0kW Reverse Cycle Split System — Maximum Single-Head Capacity

The 10.0kW Seiya is the top of the Classic Series and one of the largest wall-mounted split systems available in Australia. It delivers serious cooling and heating capacity for spaces of roughly 90–100 square metres, without the cost and disruption of ductwork or a cassette installation.

Who buys this unit

Businesses and homeowners with genuinely large volumes to condition: warehouses and their office areas, community and church halls, large retail tenancies, gyms and martial arts studios, restaurants and function spaces, workshops, and very large open-plan homes or shed conversions with high or raked ceilings.

Get the design right first

A 10.0kW unit is a significant investment and it will disappoint if it is specified without a proper assessment. We look at floor area and ceiling height (volume, not just square metres), glazing and orientation, insulation, occupancy, equipment heat load, hours of operation, available electrical supply, and how air will actually circulate through the space. In many large or partitioned spaces we recommend two mid-size units instead — better distribution, redundancy if one fails, and often a similar total cost.
