Big Maxx Heater Install with drywall anchors

[Krauts]

Just throwing this out there as a general question and hope I don't get ripped apart for it. In the past I have gone up in the attic and to mount a heater to my garage ceiling. Today I was thinking why not just use those screw in drywall anchors. I bought some the other day for another project and these are rated at 79 pounds each. The big maxx 50k btu is only 70 pounds itself. 6 of those would definitely hold it. Do they shake or vibrate too much?

is that 79 lbs based on a perpendicular load such as hanging something from a wall or a direct load such as from the ceiling. I would not trust drywall to hold it over time.

I would spend the time & anchor it to trusses
vibration can do nasty things

Not a good idea. Imo the ratings for anything drywall are inflated for shear and not for straight tension.

Really don't want a fire breathing device ever coming loose and falling down......the very least expense would be the furnace damaged beyond repair.

Attach to the framed structure that you know will hold it without a doubt.

Man i dont even use those on pictures.

Threaded rod through the ceiling into a 2x4/6 above the ceiling joists.

It's not a matter of how strong the anchor is, it's how strong the material is that's holding the anchor in place. Drywall doesn't have enough strength to handle the vibration from the fan, the holes holding the anchors would round out over time.

unistrut would seem like the way to do this, if you didnt want to get in attic. mounted to trusses, with wood lag bolts/screws

Nope !

I wouldn't trust them to hold the heater. It will vibrate and could possibly allow the heater to fall.
