Does the use of kerosene, propane, or natural gas heaters cause health problems?
I've asked this before and got general answers. I am looking for documented proof that kerosene causes emphysema and/or other health risk.
Same for natural gas or propane. My father is insisting that I give up my kerosene space heater and get a thermostat controlled gas heater. Cost, etc. are not the issues. The only issues are which of the above three heat sources cause what health problems.
