Review: I love it! - Th Bosch Cool 2000 Portable AC is brilliant! HERE'S WHY YOU SHOULDN'T GO FOR A CHEAP BRAND: I had previously bought a cheap one for sub £200. That was a waste of time as it sounded like a pneumatic drill and didn't give out anywhere near enough cold air for it - it struggled to cool the room down. HERE'S WHY YOU SHOULD CHOOSE A BOSCH: To cut through the confusing world of all the options out there, I just decided I would go for a reliable brand and spend considerably more money - Bosch was my choice and it has 100% been worth it. I only needed the smallest one as the room I want to cool down is quite small. It looks slick, it pumps out cold air in abundance. As air conditioners go it's quite quiet - I mean, obviously it does make some noise, but it's soothing white noise (a bit like the sound when you're on an aeroplane). If you want a reliably excellent portable air con unit and have the budget, my advice is look no further

## Questions & Answers

**Q: Does it have a tank for dehumidifier & what is the minimum temperature it will operate at please**
A: It has an internal tank and the display lets you know when full. Using the pipe supplied you can then drain the tank. Cooling mode goes down to 16 degrees

**Q: Does this have the ability to cool down 2 bedrooms?**
A: I have it in the hall outside 3 bedrooms. It cools the hall down very well but the bedrooms take much longer to cool and don't cool as much. If you had one in each bedroom it would be far more effective of course.

**Q: Can the hose be extended as the unit cannot be sited near a window**
A: The hose is a fixed length.  If you can't site near a window then you will need to purchase a hose that will be long enough to reach the window and hang outside it.

**Q: does this appliance have a heating function ?**
A: It has 3 functions, air con, dehumidifier and standard fan, no heat element.
