The details
Cool and heat, all year round
The Toshiba Sumato 16000 BTU is a wall-mounted split air conditioner and heat pump built on Toshiba’s proven inverter platform - cooling in summer and efficient heat-pump warmth in winter, in rooms up to 40 m². The reversible heat pump system delivers 4.2kW of cooling and 5.0kW of heating and keeps working reliably down to −10°C outside.
Efficient, quiet and long-lasting
A Toshiba DC inverter compressor continuously adjusts its speed rather than switching fully on and off, so the Sumato reaches temperature quicker, runs more quietly and uses less energy than fixed-speed air conditioners - rated A++/A+ (SEER 6.10 / SCOP 4.00, UK Average climate). Toshiba’s Magic Coil treatment keeps the indoor coil clean by stopping dust and dirt sticking to it. After you switch off, the self-clean cycle dries the coil to help prevent mould, damp and musty smells.
Comfort and control on your terms
Choose High Power mode for a rapid blast of cooling or heating, or 8°C heating to frost-protect your home while you’re away over winter. On extremely cold days, on-demand defrost clears the outdoor unit so it keeps working.
Installation & what to order
The indoor and outdoor units are pre-gassed and sealed for a straightforward install by a qualified fitter. A pipe kit is not included - this model uses 1/4" + 1/2" connections (liquid + gas), so add the correct copper pipe & cable kit for your run length (up to 15m) from Recommended Accessories.
F-Gas notice
This unit contains fluorinated greenhouse gas (R32, GWP 675) and must be installed by an F-Gas qualified air conditioning engineer. The gas must be handled by qualified F-Gas personnel. Warranty is subject to commissioning by a qualified F-Gas engineer.
