Well interesting you'd inquire! The best heater ever, it's a radiant heater!! Don't even need the "optional" fan option. Had my HVAC fella plumb it, gas line drip pipe and all. A couple years ago we had temps that had fallen below 0, actually -30deg. I could still sport my normal attire of shorts and flip-flops. Still a standing 85+degrees in "this" attached garage. When we first bought this 3800sq ft hillbilly shed the rafters previously uses were 2x4's and bowed. Knocked all that shite out and put proper 6x2's for the rafters and i insulated the crap out of it. Re-wired it placing outlets placed for handy access and implemented LED fixtures for focal points of workstations. 4x the beam of 2x12's shouldering the weight of engine shown with similar supports on each end. Suppose i garnered my knowledge from lifting houses-up off their foundations and dropping the haydite/mortar/concrete block existing foundations and setting-up forms for a poured foundation. Used to build cooler and freezer pads and foundations for Hussman Refrigeration, and remedial water tower bases for of placement silos of waste water that can't immediately be flushed into the city's managed GPH piping. Got carried away but.. Yes these birds work Fantastic.
