Toshiba
Toshiba is a Japanese manufacturer of air-conditioning equipment, covering residential, commercial and light-commercial systems. Its current UK residential wall-mounted models are published in a single 62-page UK Residential Specification, which is the source of the figures shown here.
Mid-Range
Living rooms, bedrooms and home offices — particularly where a white unit would look wrong.
Available sizes
2.5 · 3.5 · 4.6 · 5.0 · 6.1 · 7.0 kW

Specifications come from manufacturer documentation. Where a row is ACE Climate’s own view rather than a published figure, it says so. We do not rank these against each other — which one suits you depends on the room, the building and the budget, and that comes out of a survey.

|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Cooling capacityThe range of cooling capacities this model is available in — the cooling delivered, not the electricity used. Which one suits a room depends on a heat-load assessment of that room, not on floor area alone. | 2.5 kW | 2.5 kW | 3.5 kW | 3.5 kW | 4.6 kW | 4.6 kW | 5.0 kW | 5.0 kW | 6.1 kW | 6.1 kW | 7.0 kW | 7.0 kW |
| Heating capacityPresent when the system can heat as well as cool. In heating mode it works as a heat pump, moving heat in from the outside air rather than creating all of it. | 3.2 kW | 3.2 kW | 4.2 kW | 4.2 kW | 5.5 kW | 5.5 kW | 6.0 kW | 6.0 kW | 7.0 kW | 7.0 kW | 8.0 kW | 8.0 kW |

| System typeHow the system is put together. A single split serves one room from one outdoor unit. A multi-split serves several indoor units from one outdoor unit. VRF — variable refrigerant flow — is the larger commercial version, where one outdoor unit serves many indoor units that can run independently of each other. | Single split | Single split | Single split | Single split | Single split | Single split | Single split | Single split | Single split | Single split | Single split | Single split |

| Efficiency, cooling (SEER)How efficiently each system cools across a typical season, as published by the manufacturer. A higher number normally means the same cooling for less electricity, which makes this the fairest single row for comparing two systems of similar capacity. It is not a prediction of a bill — that also depends on the building and how the system is used. | 8.6 | 8.6 | 8.6 | 8.6 | 7.8 | 7.8 | 7.3 | 7.3 | 7.3 | 7.3 | 6.3 | 6.3 |
| Efficiency, heating (SCOP)The same idea as the row above, but for heating across a typical season: higher generally means more heat for each unit of electricity used. Present only where the system can heat. | 5.1 | 5.1 | 5.1 | 5.1 | 4.6 | 4.6 | 4.6 | 4.6 | 4.6 | 4.6 | 4.1 | 4.1 |
| Energy labelAs printed by the manufacturer. The scale differs by capacity band, so two labels are only comparable within the same band. | A+++ / A+++ | A+++ / A+++ | A+++ / A+++ | A+++ / A+++ | A++ / A++ | A++ / A++ | A++ / A++ | A++ / A++ | A++ / A++ | A++ / A++ | A++ / A+ | A++ / A+ |
| Sound leveldB(A) is a measurement of sound, and the scale is not a straight line — a difference of a few dB(A) is more noticeable than the numbers suggest. Manufacturers quote under their own test conditions, so treat these as a guide to relative quietness rather than as directly comparable numbers. | 19 dB(A) in Quiet mode, up to 41 dB(A) at full speed. Measured as the manufacturer publishes it: Quiet, from "Sound pressure level (high/quiet)" in the current SHORAI Curve brochure (12/2025-A). Cooling 41/19, heating 40/19.

| Indoor sound pressureSound pressure is how loud the indoor unit is at a stated distance — the figure closest to what you would actually hear.
