Cheaper alternatives to 'Dyson's Hot+Cool' fan/heater

I'm wanting something similar to Dyson's expensive Hot + Cool Fan.

I'm simply wantingnsomething that is a 2-in-1 and can Cool my small bedroom down on the warmer months and heat it up during colder months.

I also don't want anything:

• over £100
• too loud and noisey
• less than 12mths warranty.

please advise as I'm struggling finding something suitable and I refuse to pay hundreds and hundreds.

much appreciated
