Air-to-air heat pump
Transfers heat and can deliver multiple units of heat for each unit of electricity used.
Air conditioning
Comfort that works all year
Modern air conditioning is much more than cooling. Reverse-cycle systems deliver cooling, heat-pump heating, air movement and filtration from one professionally sized system.
We work with domestic and commercial customers to create comfortable spaces with room-by-room zoned control and a solution matched to the building.
Sizing is important
Air conditioner size to room size
Correct sizing matters. This table is indicative guidance only and assumes typical room conditions.
| Room area | Typical use | Indicative capacity |
|---|---|---|
| Up to 15 m² | Small bedroom or study | 2.6 to 2.8 kW |
| 15 to 25 m² | Large bedroom or home office | 2.5 to 3.5 kW |
| 25 to 35 m² | Living room or similar | 3.5 to 5.0 kW |
| 35 to 50 m² | Large living area | 5.0 to 6.6 kW |
| 50 to 70 m² | Open-plan area | 6.6 to 7.1 kW |
| 70 to 100 m² | Large commercial area | 7.1 to 10.9 kW |
Professional survey recommended. Ceiling height, insulation, glazing, solar gain, orientation, occupancy and equipment all affect final selection.
Understanding the difference
Air conditioning vs gas and direct electric heating
Reverse-cycle air conditioning uses heat-pump technology to transfer heat rather than generate all heat directly from purchased energy.
Direct electric heater
Converts electricity into heat at the point of use but does not multiply the purchased energy through heat transfer.
Gas boiler
Burns fuel to heat water for a wet central-heating system, with some losses through combustion and distribution.
The Energy Saving Trust states that heat pumps can produce three units of heat for each unit of electricity used and are more efficient than gas boilers and electric radiators.
