Unico Air HP EFA through-the-wall air conditioner without outdoor unit
At a glance
At 164 mm deep, the Unico Air HP EFA is a flat air-to-air heat pump with all its technology in a single indoor unit. Nothing is mounted on the outside of the building. It cools with a nominal 1.8 kW and heats with 1.7 kW, both in energy class A, using an on/off compressor.
How you use it
The manufacturer intends this model for smaller rooms in homes and for situations where an outdoor unit is unwanted or not permitted. Because the cabinet is so shallow, it fits where space is tight and the installer can also recess it into the wall. In daily use you choose cooling, heating, dehumidifying or fan mode with the multifunction remote control, and Auto and Sleep modes and a timer are available. The indoor fan has three speeds and moves 150 to 215 m³ of air per hour; the sound pressure indoors is 27 to 38 dB(A), measured at 2 metres. Sound-absorbing and anti-vibration materials are built into the cabinet. The air is filtered in two steps, by an electrostatic filter against dust and an activated carbon filter against odours, and a wide outlet flap distributes it evenly. Heating is possible at outdoor temperatures down to -15 °C.

Before you buy
- Air intake and exhaust need two ducts of 162 mm through the outer wall, so the unit has to go on an exterior wall.
- When the unit is used for heating, a condensate drain is mandatory. The installation manual describes how it is made.
- Fitting is specialist work: drilling the wall openings, mounting the unit and the electrical connection are jobs for an installer.
