For crews on open job sites, loading docks and sidelines who want the most heat a single tank top gives, in every direction. Use it only where fresh air moves freely.

2.9/5
For occasional outdoor use where a cheap 15,000 BTU tank top with tip-over and flame-out shutoffs is enough. Keep it outdoors, since the listing gives no ventilation rules.
