            With adequate ventilation, yes. We had this heater running in our detached garage for a family event. The garage doors were all closed including all entry doors, but it's not an insulated garage.

                    My original unit didn't function and Mr. Heater said maybe I have a faulty regulator on the hose. Went to another hardware store picked up another regulator hose only for the heater to continue to fail to ignite. So that leads me to believe the entire device is faulty and I'm out extra money for the new hose.

                    Terrible product
                    This came with the wrong adapter for typical propane tank. Really frustrating to have to lose a day. No reason to suspect that something else would be required, shows both standard adapter and regulator in the photos and video... really unacceptable.

                      Quality issue
                      The heater worked intermittently when new. The heater igniter would occasionally not work when needed and it appeared the igniter circuit not working was based on low ambient temperature. Testing confirmed this to be true. I jumped the alleged high temp cutout and heater igniter works reliably. A heater that doesn’t work when it’s cold is not useful.

                        Good price for good heater.
                        Compared this to other models and chose this one because it was in stock. Turns out it works really well. I use it in my 30 x 25 detached steel garage and it uses about 1 gallon of propane per hour on high for 20 mins then low for 40 mins. Really easy to set up and use.

                        Works Great!
                        I bought this heater today for my building and was really impressed with the amount of heat this thing puts out. It was easy to put everything together and fire it up. For the price I would recommend it to anyone.
