Heat energy sources do not support producing pollution.

It's a bit annoying for mod that use heat as energy source but still want the entity to pollute like 99% of entity of factorio. Example https://mods.factorio.com/mod/big-heat-furnace want its furnace to pollute but it doesn't

+1. Imo, pollution should be independent of energy sources and the like, everything should be able to pollute regardless of what kind of power source its using.

How peculiar! Also heating towers generate pollution, while producing heat: https://wiki.factorio.com/Heating_tower I do not understand...

Yeah, because it's a reactor prototype, like a nuclear reactor. Plus, it generates heat, instead of consuming it.
It is quite strange why stuff powered by heat isn't able to produce pollution though.

I've added support for the next release.
