I don't know a lot about how radiators work, but I'm confused as to why you would have a chimney if you didn't have a fireplace. If there's no fire to create smoke, then there's no need for a chimney for the smoke to go out of. Perhaps I'm wrong about this and a radiator expert will set me straight, but this seems like an odd premise. Still, it shows why Olive Oyl eventually left Harold Hamgravy and stayed with Popeye. Popeye would never do anything this silly. Or perhaps he would, but he would be strong enough to punch his way out of the radiator.
