If hell has both a lake of brimstone (between sulfur melting (115 C) and boiling (444 C)) and a cold dark place (assuming uncomfortably cold to be less than 20 C) there are going to be some serious temperature gradients.
I'd start building a heat engine to tap the temperature differential and get some work out at say, half Carnot efficiency (22% @ Th=550K Tc=300K). That work will serve nicely to drive an air conditioner (COP 4) to pump some more heat from my part of the lake to the cold place.
As always, the engineers will be using what's available to make their local environment more to their liking. Once my vicinity is a comfortable temperature, bits of the lake are solidified and ice made, I plan to open a bar. Demons welcome if they behave themselves.
That's pretty, ahem, hawt.
