Hi all, just hoping someone can give me some advice on choosing a
propane powered space heater for my garage. It's about 350 sq ft with

9' ceiling, so 10 - 15K BTUs should be sufficient. If you've had
experience with any particular make and/or model, good or bad, please
share. What are the pros and cons of vented and ventfree models, etc?

Any advice you can give is much appreciated!
