if it's a proposal, please move it to the proposed_feature space
but what's the proposed feature ? only adding substence=hot_water and 
temperature ? others tags already exist.
or it's a howto draft ? or a user talk page related to this question ?

in this case, steam is also not a substance :-)
if you want to be a purist about words, it should be
substance=water or air (or oil although I don't know any of them)
usage=heat_transfer
and for substance=water, state=liquid or steam/gas
