Selling Dyson Hot & Cool Tower in nearly as new shape. Remote controler included. Original box as well
It can keep you either cool or warm (just search for reviews and you will be convinced why to spent £350 for heater).
We have used it one winter for very cheap and effective heating (our supplier didn't even raised our payments). One big room heated in ten minutes after we were back from winter holidays. And of course for cooling ourselves down in summer (well, it's still England here, so not so much cooling in summer as heating in winter).
We have now moved and there is both fan and wall heaters which are functional, so we don't need tower anymore.
