Thermostat Location - Garage

[AldeanFan]

I have a 20x22 garage I heat with a MrHeater Big Maxx we installed in the Fall. It hangs in the back corner pointing accross the garage. When I installed it I put the thermostat next to the man-door, but now I realize the furnace points right at the thermostat.

What is the best place for the thermostat? I assume it's in a bad spot now.

Thanks

I've been taught to use an inside wall, away from any HVAC vents. Bet you don't have an inside wall, but in my case I have a ply sheet on the wall for the breaker panel and stuff and mounted my thermostat there. It's been fine, the location is directly under the heater.

So my recommendation: directly under the heater, but use something to isolate it from the exterior wall.

It is just a gauge, unless the heater is blowing on it, shutting down and not getting the whole area to a comfortable temperature, set it to temp that makes the area comfortable to work in.

No it's not just a gauge ! They have heat anticipator said in them for a reason .
But given your set up , put the T- stat on a wall away from direct air flow of the unit .
There were jobs we would mount the T-stat directly below the unti with a pipe or iron.

Yes, that's why I said, "unless the heater is blowing on it and shutting it off before the room is comfortable" My point was, I get calls from people all the time who say things like " I have my thermostat set to 70 and I'm still cold", just because it is 70 right at the thermostat does not mean the whole room or the area where you are is 70, adjust the thermostat to a temp where you are comfortable.

In general, off exterior walls, and by the return of any system. If exterior wall is the only choice, mount it on a bracket that gives it some space so it's not picking up on the wall conduction. Avoid being across from a window that gets direct sunlight too as you want to avoid the radiant heat.

Ok

One of my pet peeves is over sized equipment , I like to have my equipment sized on the very edge of the demand.
Nothing worst than trying to explain to a client why it should run Rather than cycling on and off all the time.
A steady state of heating will heat a room a whole lot nicer than the on and off .

That's one of my issues with the non tech people on this sight , they want a bigger unit rather than a heat load to get the right one. Most heat load calculations are fudged on the high side anyhow. Of course having ALL the info I required.

At one time Rheem furnace co recommended the T-stat to be right above the main house return air and it makes sense
