When I deep condition my hair I typically like to leave it in for at least 6 hours. There is debate on whether it is necessary but I find that it does my hair wonders so that is what I do. It's important to do what works for your own hair as opposed to jumping on every bandwagon. Deep conditioning is important for my hair as I have been protective styling for the past few months and plan to continue till the end of winter.
I don't use heat when deep conditioning except when I use my steamer. I find that if I wrap my hair/head there is enough body heat generated to get the job done. This also enables me to deep condition on the go and in style. No one would ever know that under my head wrap is a shower cap and hair full of deep conditioner and oils. :)
