I've used a 40K BTU propane 'torpedo' style heater for a number of years and it's worked fine in terms of heat output. However, it's showing it's age and I'm starting to have problems, and I'm wondering if replacing it is the best way to go, or if I should perhaps look at a kerosene/diesel torpedo heater. I use it maybe a 10-20 days in a year. I'm not looking for a 'built in' option, I think that will be way more than I have to spend.
The most annoying thing about the propane is that if everything isn't waxed up to the gills I get a fine layer of rust. Just wondering if the kerosene style will do the same thing, or if it puts less moisture in the air. I've noticed that most of the kerosene heaters have thermostats and will turn themselves on/off which is appealing. Once the garage is hot with the propane, I have to turn it off manually, and then back on when I start freezing again.
Two other concerns are operating costs and smell--
Thoughts?
