Portable kerosene heater ideas please

[Cranky]

Propane is a pretty clean burn. They can run off a gas grill tank.

I use one of those single round tank top heaters when needed but if I run it on medium, I don't smell the fumes. On high, it'll stink up the place! Thought about getting a bigger tank but the 20 pounders (when empty) are kinda getting heavy for this old fart when full.
