How can I reach 49 degrees Celsius in my room?

My current place is here in Doha, Qatar. I need to exterminate these bedbugs. How can I reach that temperature without harming my appliances? (HDTV, Computers, USB, AC, Microwave oven, Carpets etc.) and also not burning my room down and not starting any KINDS of fire inside. and I need to be alive!
