Space Heater Conversion!!!!!

Hi people
I have a diesel /parrafin space heater
I was looking at the indirect space heaters online as they seem to be less toxic than mine.Apparently they blow clean air.My space heater stinks they garage out even with extraction on.

I was wondering would it be possible to convert my heater from direct to indirect??

Any ideas much appreciated

Thankyou!

I don't know anything about this, so go to Google and look into it.
I find that this is a good way to start, at least in my inquiries on trying to find "How do I make an induction welder" or what ever I'm curious about.
I hope this helps.
Rich.
