Yes, this version heats. You can actually see the functions at a glance in the picture of the operating elements. There are no secrets :)

This here is appropriate: Electrolux Fensterkit

Behind the product are the filters and the hose outlet, with the socket for the power supply.

2 meter.

Mine works ok, except for the hellish noise it makes. Impossible to sleep with the unit on. You might be able to solve your issue by NOT putting the fan on Auto. Choose low, medium or high instead.

In cooling mode at full load (i.e. actually always in use) 1450W according to the label. Cooling capacity (3400W) by EER (2.6) would be "only" ~1308W, which is probably rounded a bit but is written large on the energy label. With my not too economical use, it cost approx. 200 Fr. last summer.

The unit has a container for condensation water. In cooling mode, most of it is released into the air by evaporation. If the unit is used for heating or dehumidification, the container fills up. However, there is also the option of connecting a fixed hose to drain off the condensation water.

Tube: 15 cm / attachment (oval) at the end of the tube is 6 x 15 cm (inside)

As far as I could see, this is not specified. However, it does say in the description: "To prevent too much warm air from entering the room from outside through the opening required for the hose, the outlet should be as small as possible and located higher than the air conditioner. The easiest way to achieve this is to hang the end of the hose from a tilted window." If you want to use it with the Electrolux window kit EWK04 (which is linked as an accessory), you should follow the specifications in the description of the window kit.

No. Window mounting kit must be purchased separately.

It's expelled with the warm air. There's some tube on the back to drain liquid, but definitely no tank. And we had no need to use the hose all of last summer. Please be warned that this unit (just like all the other single hose systems) suffers from the drawback that it needs to suck the air from somewhere, and that somewhere will end up being outside. So the efficiency in the end is quite a bit diminished. You can convert it to dual hose system (gangsta style), but yeah, it ain't pretty.

The supplied hose can be extended to approx. 1.5m (which should be sufficient in most cases). I could not find a direct extension, but other similar hoses with a diameter of approx. 15cm should also be usable.

The one for 499.- cannot heat. This one, on the other hand, can.

In such a case, I would recommend contacting the customer support directly. They can advise you best.

Mmh yes, an irrigation computer is certainly a good thing. I suppose you want to integrate the air conditioning into the irrigation system? The whole thing sounds interesting. Can you keep me posted and also send pictures of the system? And yes, the air conditioning is great! However, I don't know the coupling size of the ventilation system. But I could imagine that it would fit together. Have fun building!

You can, but then you have to carry the full boiler with the hot air to the door by hand every 90 minutes and empty it. Seriously, where is the heat supposed to be transported to if it cannot be dissipated via the exhaust hose? It's not as if the heat that the unit takes from the room simply dissipates. The heat has to go somewhere. With this type of air conditioner, it has to go outside via the hose.

Yes, an exhaust hose (hand organ style) is included.
