I have used this to take the chill away inside my 2-car garage last autumn so I could stain and apply finish to poster frames. It worked well despite having 12 foot ceiling. It lights easily if you follow the directions. The only drawback is a standard BBQ-size gas cylinder only lasts a couple hours on the high setting, so you might consider a larger cylinder if you have space and can handle the weight. Overall it does the job just fine
