Joule - Electra: Just How Hot??

I'm considering Joule Electra mono blocs as a source of amplification. My fundamental question is not about the sonics rather this is a question for those that actually have J-E in their system: How much heat do they throw off and how do you manage--especially in the warm months of the year? Or is the heat issue not really a major problem? My room is 25 X 17 X 13 (LxW xH)with 4 air conditioning vents and 2 heat extraction ducts.
