Slide down to -30°C. See who holds on.

At -8°C, all eight are close. It’s lower down that it plays out: below -27°C, the CU 12,000 and the Airest stop, and at -30°C the CHU 18,000 keeps 52% of its -8°C heat.

On-screen colours are a guide only: the real shade changes with the room’s lighting.

05 · Quiet, in decibels

The quietest Sharp wall unit goes down to 22 dB.

That’s the CHU 12,000 at its lowest fan speed. Québec.ca puts a whisper heard from one metre at about 20 dBA.
