I had two very basic 12BTU units in my very large living room (about 320 m3) and they were unable to provide any form of significant cooling/heating.
Due to cable restrictions 18BTU was the max I could install to replace these units and I did not believe that increasing the existing capacity by just 50% would make the full difference.
However I was pleasantly surprised. These units adequately cope with both heating and cooling my room. They are silent and the air is comfortable.
My only regret is that compared to the previous range the programmable timer has been left out, which I found very useful.
Personally I beleive that the output of these units is more than double my existing units, while my electricity bills have not significantly increased. So great performance and the units look good in any type of home environment.
