Issue description

This is kind of a duplicate of #5301, but for heaters in particular it's not just an aesthetical thing. You'd expect heaters to melt ice, and if you use a temperature mod, prevent you from freezing to death. But they do not, because they do not emit light outside of their own texture.

Hmm interesting. Not sure why it isn't visibly giving off any light for you (unless this is something we changed more recently, though I don't think it is). Though it seems the reason that the ice isn't melting is when active the heaters give off a light level of 8 for a bit of ambience (without performance issues from as many light updates if machines are going on and off), but it looks like ice only melts at like a light level of 11. Definitely will need to think about this more (and maybe make heaters specifically use a light level of 11 instead of just 8, unsure.

My apologies, I shouldn't have tested on 1.15 (I did that because I don't have a temperature mod on 1.19). On 1.19 they do indeed emit light. I have changed the title of the issue.
