Let me tell you, this heater is an absolute game-changer for my uninsulated 30x30 workshop. When that ice storm hit and temps dropped to 16°F, I was skeptical - but this unit had my shop toasty at 80°F in no time. The heat output is insane, though I learned quickly: spring for the 100lb propane tank unless you want to babysit 20lb tanks all day.
The quiet burner tech is legit - it's noticeably less obnoxious than the diesel heaters I've used before. No more shouting over the roar or dealing with that nasty kerosene smell. The 10ft hose is perfect for positioning, though it does get stiff when cold (pro tip: warm it indoors first).
Safety-wise, I was impressed. The exterior stays cool to the touch, and with my roof vents, I didn't need to keep doors open. That said, I still keep my carbon monoxide detector handy - better safe than sorry. The thermostat works well, though there's about a 20° swing between cycles in my space.
Only gripe? The connector isn't standard BBQ-style, so I'll be swapping that out. But when you're thawing ice off your building walls while it's blizzarding outside, that's a small price to pay for this kind of heating power.
