Mounted it in my converted Mercedes Vito. The 4D has no trouble maintaining 20°C inside even during frosty Baltic nights. Definitely worth the upgrade from the 2D.
Die Air 4D ist super für unseren Kastenwagen-Ausbau. Besonders leise im Eco-Modus und schnell warm. Lieferung kam sogar früher als angekündigt.
Heating power is solid, but the fan gets a bit loud above 75%. Also, the oled controller display backlit is somewhat dim, which makes it hard to read in the dark.
Leistung top, aber die Fernbedienung reagiert manchmal verzögert. Sonst echt zufrieden.
Used the Air 4D during a week-long fishing trip. The heater ran non-stop without issues. Fast delivery, very well packaged.
