I don't think so the 7kg can fit the comforter. The drum is not big enough. Have you try before? I ve survey all the brand and ask. The minimal kg can wash comforter is 11kg and above. Have you notice that 11kg below washer don't have comforter selection. Only 11kg above have the selection.

You can conceal the hose but to extend, you need to use flexible aluminium ducting. Can get it at ACE hardware with many lenght selection. This type of dryer is an old tech and consume a lot of electricity.

You need to survey more. High speed spin not necessary good. Bad for cloth and short life washer if balancing is not good. If the spining rpm can be select, than it is ok.

Good morning.    It is not the weight problem cause the comforter is very light. Even king size. The 7kg can rotate higher than that. I mean the drum is small and you need to stuf in hard to fit in. The water and detergent can't move around and you don't get a clean washing. And when spining time, your washer maybe can dance out.    I did ask a few shop and all tell me the same. Must at least 11kg. And it is true I don't see any comforter selection on it. The maker know best that what the max can fit in certain of their washer. So I buy and obey their spec. Not my spec cause I want to takecare the washer too.
Not really that expensive. I brought the LG combo 12/7kg cost RM3700. If divide, RM1850/pcs. So how much both washer and dryer you brought?
Maybe you miss understand the watt power and the way it running. I learn and search around how and what type of dryer is best and save power. Cause I first time buy dryer also.   The venting type will draw the power continueslly cause the hot air will blow out from venting and draw cold outside air. So if state 2.2kw it mean really draw 2.2kw continue till your dryer stop. But I think the new type did improve more.
While the heat pump and the steam type will recyle the heat back to drum. No heat loss. As long as the heat is still between preset, It won’t on the heat. It is not continue draw the power even it state at 2.1kw. It is how it save electricity. And no ducting need. But one thing bad is, the smell of detergent won’t go away cause the hot air keep circulate inside.

Yes, it is the same. Some name it blanket, duvet or comforter. If the drum big, no problem.

I did consider separate unit. Worry spoil fast. But my house is small, the dryer is big and don't have the technology I m looking for. So no choice but to get the combo type to save the space. I didn't consider the europe brand as I think it is over price. The japan and korea ve same quality as long as it not China brand.   Survey alot but still can't get the lowest price. Thanks to one of the forumer here who intruduce the local online electric shop. Jintex.com.
Anyway, seldom use the dryer side. Try to save power. Unless raining time.

First I also see their shop don't feel good. But the boss is friendly and direct send to my house with install.   The deal is very flexible. He give me few choice. Buy online or send the item to my home and pay or go direct to his shop. Since it is my first time deal, I choose to go direct to his shop. Because I already decide this model, so no show unit doesn't matter to me. (actually I never see this washer before and only read it from LG website and commend from forum).
Jintex also didn't carry this brand and model that I want. I email to him ask for this model and price. He respond and I straight deal with him.

Use the flexible one. For easy install. Don't worry. It can last long and can stand the heat till 600c.  As long as you don't poke a hole to the ducting and install with care.

I brought before and I know how is it.
