Morning everyone. I'm thinking of buying one of these. Does anyone have any advice and/or specific models they'd recommend? Thanks 🥰

In countries where you need AC most of the year "Dual Hose" is more common on portable units, as they are 40%-50% cheaper to run than a single hose design, but the purchase cost is higher.

Single hose units are inherently inefficient for two main reasons,

As it blows air out of the room, warm air is sucked in to replace it, through gaps in the floor, windows and vents etc.
The cooled air in the room is used to cool the "hot side" of the unit. (which might sound sense, but the heat differential is so great you might as well use the ambient air outside, for "free".)

Dual hose systems, don't reduce the air pressure and don't use the air in the room to cool the "hot side"

I've been unable to find anyone selling "dual hose" portable units in the UK, I would love to know if anyone can find one.

Quite a good explanation

After another heat wave and also looking for dual hose units, I finally found the EcoFlow Wave 3. Currently £799 at full price for the version without a battery (sold out right now) although they always seem to have some sort of discount. I decided to go for one because they are actually portable (approximately 13.5 kg for the base unit) rather than the usual "portable" units on wheels that are 20kg+

Will report back when it arrives.

As I read it, the EcoFlow Wave 3 is still effectively a single hose design, but I will be interested to hear your feedback once you have received and tested it.

@Imunravelled I would be interested to hear your thoughts too. It doesn't look like any others I have seen.

Ah I see @Imunravelled. So .....with a portable unit it's not just a case of park it near a window, poke the plastic hose out of the window and jobs a goodun?

Some thought has to be put into how to "seal" or cover the open part of the window through which the plastic hose is poked?

That's exactly what we do,put it near a window,hose out and shut the curtains around it to seal it as much as we can. We have a 20 year of Delonghi and it's great. Noisy though but gets the room really cold when the heat gets too much . We paid about £350 at the time and it's still going. Keep the door shut to the room.

Can you explain why you think that? I'm not asking to be snarky - genuinely interested as to what the difference is. It has both an inlet and an outlet hose.

Having read the manual again, I stand corrected this can be used as a dual hose machine.
