Electrolux EXP09HN1WI Portable Air Conditioner, White

Product information

The Electrolux EXP09HN1WI portable air conditioner features the latest heat pump technology to provide high performance air conditioning. It features a unique window closure plate which aids the system in venting hot air to outside the building. Suitable for rooms as large as 20m², it has an energy efficiency rating of A for cooling and A+ for heating. Auto Operation mode will select the appropriate operation depending on room temperature, so you can let this conditioner respond to the heat in the room, without having to change settings yourself. It will also go into sleep mode once the room as reached optimum temperature levels. Built in healthy dehumidification will ensure that you’re receiving clean, healthy air. A remote control means that you don’t even have to leave your chair to change settings.

A quick guide to air conditioning
Unlike fans that simply move the air around, air conditioners actually reduce the temperature. The hot air is drawn into the unit over an evaporator, which contains a low pressure and very cold refrigerant. The cool air is then blown out through the front vents while the hot air is expelled through a rear hose.

Mobile units like this one can be simply plugged into the mains socket. You need to make sure the hot air is extracted, along the hose, through a small hole in the wall. 

Please note: Mains lead - 2m / Exhaust hose - 1.5m

Q & As

Rated 3.9 out of 5 by 14 reviewers.
Rated 4 out of 5 by Great cooler During the recent hot weather, we literally turned it on an hour before bedtime and it instantly cooled the room. It's loud so we turned it off to sleep, but with the door shut, the room stayed cool for hours. It's great except for being advertised as 'portable', we had hoped we'd be able to move it between the sitting room in the afternoon and then to the bedroom at night, but after a couple of times we realised that this wasn't practical as it is heavy and a little awkward getting the tube comfortably out of the window. 20 August 2014
Rated 5 out of 5 by Great unit, does the job We live in a shared Victorian house in London with an en-suite bathroom that unfortunately has the boiler inside. All summer the room as been between 26 and 33 degrees - unbearable even with two fans pointing over the bed! We turned this unit down to 17 to see what it could do and I woke up in the night and it was like the arctic so it works well. I think the temperate was about 18 or something but I don't know how accurate my thermometer is. It's quieter than the two desks fans we had before. The build quality is better than other air cons I have seen. The remote is really handy. Definitely worth the money. 08 August 2014
Rated 5 out of 5 by Excellent machine I've had one of these for a year now. It's a very good unit - the build quality is clearly a lot higher than some of the unbranded 'DIY store' versions you can get. It looks attractive and the opening / closing top louvre is a nice touch. It cools really well too in a 5m X 4m bedroom. Portable air con units are quite noisy by their nature and this is certainly not silent, but it is quieter than another unit I have - the aforementioned unbranded DIY store unit - the main noise you can hear is rushing air. Some things to note - the window fitting kit will only work with a sliding or sash window. If you have a regular hinged window then you'll have to just put the hose through the open window and try to block the gap. This is the case for all portable air con units though. I've now drilled a hole through the wall and used the supplied wall fitting kit - which is a much better solution. If using this to heat or dehumidify you need to attach a hose to the back to drain off the condensed water. You don't need to do this when cooling - there is a drip tray which may need emptying at some point but I haven't needed to do this yet. All in all I'm very happy with this,and I'm considering buying another. 25 July 2014
Rated 4 out of 5 by air conditioner bought an extension exhaust hose that fits very well and is approx 3m long, air con unit works well with hose outside (small window on bay top opening) tip given to me by Electrolux employee was to use the cardboard box unit comes in and make template for window, cut out exhaust hole etc did this hot air stays outside, unit cools 13'X12' bedroom from 24 down to 19 in approx 1hr 25mins. Slightly noisey but then again 25-30 degrees last few days think I can live with it! would have got 5 stars but for the exhaust supplied #short# and noise. 17 July 2014
Rated 2 out of 5 by The venting of the portable cooling unit not as expected We have had a portable air conditioning unit for nearly 10 years and find it invaluable in the hot summers to reduce the temperature in our bedrooms from over 27 degrees to 19 degrees. We bought this to replace an 8 year old portable air conditioning unit and needed a unit that we could vent through a small,outward opening bedroom window in a modern house (not a sash window). The exhaust pipe supplied to vent hot air (required when cooling) is only 1.5 metres long and stems from the lowest part of the unit. The pipe will not reach even the large opening window in our bedroom. This means unless we drill a hole in the wall and permanently site the unit we cannot use the unit to cool a room. Prior to ordering, I didn't check the length of the exhaust pipe supplied as our other units all have longer pipes as standard. We have spoken to Electrolux to see if they can supply a longer pipe but they do not, neither can we use an extension pipe as this would invalidate the warranty. Unfortunately this means we have to return the unit. The delivery and service from John Lewis is not in question but we are disappointed that the product is sold as a 'portable' unit but in our case is unsuitable because we only need it for cooling and cannot vent the hot air without drilling a hole in the wall. 24 June 2014
Rated 5 out of 5 by Much more fuel efficient My husband and I bought our house without a heating/cooling system and have finally decided to use these heat pumps for the time being for financial reasons. (We had plug-in heaters before.) We have three of them and have properly installed them by drilling holes into the house's walls. Though this was very hard work on my husband's part, it has been worth it as rooms warm or cool very quickly as needed and the cost of the machines will be made up in electricity savings within 6 months. From what I can tell, the less favourable reviews of this item mostly result from not following the directions. We love this product and recommend it to those who are willing to spend a few minutes reading the instructions. 26 November 2013
Rated 4 out of 5 by Very Efficient This is a very effective air conditioner indeed! Very powerful. It's only been running for a month (I use it to cool a wine storage room) but it seems solidly built and hopefully, reliable. I agree that the hose is flimsy, but it does connect solidly if you wind on the end connectors properly. It is somewhat noisy, but air conditioners generally are. 13 October 2013
Rated 2 out of 5 by What they don't tell you in the product description... The hose for expelling hot air is a fat 15cm in diameter. Looks ugly from the street when I stick it out the bedroom window. You can’t secure the hose into the machine. All you can do is wedge one end of the hose into a hole in the machine. It can fall out easily if you move the machine or the hose. The other end can easily fall out of the window as well. If you don’t have a hole in the wall for the hose and have to use the window then you have to use the window closure plate (supplied) otherwise cold air will be escaping outside the window with hot air coming in. But the plate is 70 cm long. Too wide for many home windows. Made of extremely hard and tough moulded plastic so difficult to cut. The plate will only work with windows which slide open vertically or horizontally. NOT windows with hinges (like most house windows). The machine's vents are facing upwards rather than straight ahead. So top half of the air in the room much colder than the bottom half. Need a high noise tolerance level because of the large rotating drum inside. Even at the lowest level is noisier than the average fan. Could not sleep easily with this thing on. Could even hear the drone at street level from the first floor window which had to be left open. Not as quiet as those small wall mounted air conditioners which you see in offices. You are advised you to leave 30cm of space on each side of the machine so it takes up a lot of space. Can be used as a heater but the hose still has to be pointed out the window .So cold air will come in and hot air escape. If you use the de-humidifier option then you need to attach a hose (not supplied) to a tap at the back of the machine to drain the water collected. The machine collects some water anyway in normal a/c use which needs to be drained regularly. Not convenient. It is a lot more hassle than using a normal fan. Then there is the issue that a/c machines tend to breakdown fairly regularly… 03 August 2013
