Heat Where You Need It.
Construction & job sites
Keep crews working and materials at temperature through a cold snap. Roll it in, point it where the work is, and go.

Spot-heat a work bay or an open warehouse without heating the whole building — 150,000 BTU covers up to 3,600 square feet.
Concrete curing & drying
Hold temperature for curing concrete, drying drywall mud, or keeping coatings and adhesives in their working range overnight.
Tents & temporary structures
Keep an event tent, temporary enclosure, or outdoor workspace comfortable when the weather turns.
Emergency & backup heat
Furnace or shop heater down before a freeze? A 19-hour run time gets you through until repairs are done.
Seasonal & short-term needs
Only need heat for a few weeks? Rent for exactly the cold stretch instead of buying a unit that sits idle all summer.
