Of course a mobile unit. Is setting up the isolation for the exhaust air a huge hassle?Buy a portable one, I got one 10 years ago for £300 still going strong, vents through a pipe out the window.
Well worth it, though I've not had to use it much even in this weather a fan usually keeps me cool but I turn it on now and again just to bring the temp down.
Yeah this won't be running all the time, just a temperature reset 2 times a day. Holy hell we'll have 30C at midnight the next 3 days in Western Germany. It's time to adapt to the changes. We have cities on this planet that shouldn't even exist.
