Hi, I’m Barb from Calgary Alberta. We are renovating the garage in our early 1970’s bilevel; the garage takes up half of the basement level with 3 bedrooms directly above. The garage was originally heated by forced air vents which are no longer to code, so we sealed them up and spray-foamed insulation into the ceiling to limit heat loss from the bedrooms above. To keep our garage temperature above freezing and provide air movement, our contractor recommended a natural-gas powered heat/fan unit called a Hot Dawg, which was mounted to the ceiling and vented out the side of the house. This supposedly quiet unit (according to the manufacturer) has now created so much noise and vibration through the floor in 2 of the 3 bedrooms that we have to turn it off at bedtime, defeating the purpose of installing it in the first place! Is there any way to dampen the noise and vibration transfer through the joists? My husband wants to try sandwiching rubber washers between the mounting bracket and the unit itself. Or are we better off removing it and replacing it with a wall-mounted electric heater/fan unit? Or is there another option out there? Please help!!

Source control, ventilation, and filtration are the keys to healthy indoor air quality. Dehumidification is important too.

What is this about everyone being banned? how, when and why did this happen?

LOL! That's the most succinct explanation I've heard!

exactly how is the unit mounted????

Hey, now..no mounting talk will be allowed, you can be banned for that now.
Take it to another site, Taunton is very strict about that stuff.
G'head, join the crew that actually knows what they are talking about. You have shown us that you lke to play along, as we all do, no harm, no foul, but your input has been less than stellar and may have been outright dangerous at times , I refer to the shocking incidence you tout, and also the paint fiasco with your dog..all noted here at BT.
So, uh, why don't you advise the dear deer in your headlights to join you elsewhere? After all, you are the Industrial Merc..right? And a gods gift to wimmen, right? Ohhh, I forgot, you have everything tool wise..even concrete viberators in / on your truck! And CNC lathes, and powertrains for the Los Angles class subs..oh, silly me.
Well, you have me on your Ignore list, And I am not suprised! I'd hope that Jarlid would share his doctor with you, if it would help the gen pop of BT and unwitting people that may cross your path.
I think you are a fine upstanding person, and probably a good worker, but I'd be afraid of having you close to my most treasured..it's about trust, I don't feel it nor see it.
So as a peace offering, I'll just say, and warn you, that the site is colorful lately, and if you want to get on my stuff for what I have to say about my perceptions of you and your behavior, we'll have to email or talk, we can't do it here. OK?

A sheet of plywood was screwed into the joists, covered over with a sheet of metal (a heat barrier?), and then the heater was hung with about 1" of clearance by a pair of L-brackets mounted to the top of the unit (provided by the manufacturer).
We need to provide some heat to the garage because of the bedrooms above, the rest of the basement to the side, and the fact that it can drop to minus 40 during the winter here! Being early 1970's in design, the house was not designed in such a way as to be able to isolate the garage the way a modern garage-forward house is. The connecting walls are not built as exterior walls, and don't have the required R-rating to leave the garage unheated.
Thanks again for your input!
You couldn't have a worse mounting system to transfer vibration. (well you could but...)
Yeah great, huh? But what can I do about it, short of ripping it out ($2000 later) and replacing it with something else?
Just a quick search yeilded these

If you have the room to drop the unit down . You mount the hangers to the joist and then use a short piece of all thread to hang the heater to them.
Very simple job. Iso hangers est @ 20 ea. 3/8 threaded rod, nuts, lags, and YES to the 5/8 sheetrock. You may need to adjust the vent and the supply should be flex or have enough room to swing joint it and your done.
Hell the unit is only 400 or so bucks. At 2K I'll do a road trip. :-)
isolation hangers would be the way to go....
look into replacing the ply with fire rock...
who is the mfgr of your unit??

Sounds like the fan is out of balance. Most do not vibrate.
I'm sure it can be isolated from transferring vibration and noise to your structure. Can you give us details on how it's mounted?
From an industrial perspective, a company called Lord offers a huge amount of vibration isoltaion solutions and may help with ideas.
There's a chance that the fan could be out of balance, but you're right, it's probably just the rigid mounting.

Why heat a garage?
Sounds like no isolation hangers were used.
You could also mount the unit to the concrete wall using uni-strut.
