Well it was damn cold last night and you only went through a half a firebox rather than a full one by just placing the stat at the floor? That doesn't seem to make any sense to me. With the stat near the floor it's going to read a warmer temp because the floor is 80 degrees but the shop should be whatever you set the t stat at 4 feet off the floor. If the stat was overshooting the slab just wouldn't run for a long time. It is my understanding that a floor sensor is helpful when you have an alternative heat source in the room like a modine or a wood stove. This would keep the floor from overshooting in the case of another heat source adding heat to the space.

There is no dude pulling his hair out up top there.  Floor reading was 77 with IR gun last night, calling for heat, T stat at 4 ft high was at 63, so some ceiling fans maybe?

[hondaracer2oo4]

Well radiant is typically good keeping the heat low to the ground where you want it instead of forced hot air where it all flys to the ceiling and you need to push it back down with a ceiling fan. So we are all on the same page what size building is this, what type of construction, how is it insulated?

[hondaracer2oo4]

I just found an old pic of your pour over. Walls look spray foam, what's the ceiling insulated with? How warm is it up at the ceiling?

[coolidge]

Ceiling has R 40 foam,   Floor temp 66, peak of roof temp 62

Web thingy is just not going to work for me I guess, can't stay connected to it for more than a few minutes.
Range extender freezes the whole works also.

Have to find something else.

[hondaracer2oo4]

I would try giving the company a call and ask them about your issues.

left my shop T stat on the floor last night again, seems to be working better, only used half a box in 12 hours. will order some better T stats if they are out there, some reason i don't trust the Walmart specials.

I am also going to add my Modine back into the shop so when i open the door it doesn't take two days to come back up to temp.

[hondaracer2oo4]

Hmm this still makes no sense to me. If your floor was using another half a box full of wood then it had to put the btus somewhere. So the shop should be way to hot. Strange that it takes so long for your shop to come back up to temp after opening and closing the door. Everyone with a radiant shop floor says this is where radiant shines, the warm slab brings the room right back up to temp.

Weird, just doesn’t seem to make much sense. BTU’s are going somewhere. My buddy built a new shop, keeps it at 75 at all times, I hate it, too freaking warm, that and I think his slab temp is way to high. Within ten minutes in there for a birthday party I found a chunk of scrap plywood to set on the floor for my feet, felt like somebody dumped a quart of warm water down each shoe, my feet don’t get cold anyways but that was ridiculous.

I am going to try a new T stat, maybe move it too a different location,
My trusses are open right now, with R40 foam in the roof, might check with my drywalled and see if he can drywall the ceiling anyway.
sh?t i might even have a blower door test done on the place.

[hondaracer2oo4]

Yes, if the boiler burns another 1/2 box of wood then it had to take the btus and send them somewhere. If you moved the thermostat near the floor it would just keep The building cooler since it is closer to the 80 degree floor. This is a shop, how's your garage doors air sealed? They can be a big air leaker.

Ok, this is messed up,  while pulling out what's left of my hair last night screwing with controlyweb thing I was thinking of what the guy who did piping whenever I moved the 250 down there.

I believe he told me " you want to pull the water" through the system.
I can't confirm that yet, getting 4 yr old ready for school..

[hondaracer2oo4]

Pulling or pushing water doesn't matter as far as losing btus somewhere.

Have you thought about ceilings fans at all? I can’t hardly believe if the slab is 80 something and 4 four foot off the floor its that much cooler. I just have insulation on the roof of the shop as well. 12 1/2 foot tall door then the rafters start. I installed ceilings fans awhile back and used a Goldmine controller to run them, have a sensor up there about a foot lower than the peak, when running the peak temp is about the same as what the T stats are set at, without them it could be 20-30 degrees warmer at the peak.
