Kelvinator KWH39HRF (3.9kW / 3.6kW)

Is it powerful enough? – I am actually reviewing the KWH39CRF (identical, except cooling only), so rather than create a new category I'll use this one. To start with, the fresh-air vent hole is larger than usual, so that's a plus. Noise is good. I just don't think it is as cold when set to 16°C as the power output indicates (and yes I'm keeping the drain plug in as the manufacturer recommends to active the splash-cool system). It needs to cool a combined kitchen and dining room. It was a good test today when it was delivered because the outside air was only (a humid) 21°C and inside was 24°C at the start of the test, so I would have expected bone-chilling air from the front of it after a few minutes. A good 40°C day will put it to the test.

In retrospect though, I should have gone for the deeper KWH52CRF which is the maximum for 10 amps.

EDIT 4/3/25: We've had one 40-degree day so far and it is appearing to cope, but takes some time to cool down. With summer now over there is no chance of a 45-degree day to really put it to the test. Nevertheless, I've increased the number of stars to four.

Underpowered – Room 10x3 metres. Outside 35 Celsius, inside 23. Set to 16. Not good enough. Quiet unit. Follow me setting has no effect. 50 kg was difficult to handle.
