A few key notes
building is for profit and not a hobby shop
16’ from slab to underside of metal deck
about 10,000 SF 70x135
4.5k sf bays with lifts, 1k sf break room/parts/ equipment storage/office 2.5k sf tool/lathe/milling area 1.5k sf storage/indoor overflow parking
building located in central MS
natural gas is at the site
building will have AC As well.
I have read a lot of posts here that discuss the amount of time needed to bring it up to temperature and the fact that it is better off to leave it running all the time which brings up the cost issue of natural gas. most of these comments come from people in habitually colder climates. The temperatures at this location very seldom get into the 20s. so I am thinking the Delta T I am trying to achieve would not be that bad as related to the natural gas cost. am I correct in this thought or is that just not how this system works?
The other question I have relates to the insulation below slab which it seems 2 inches is what is recommended. in this climate in this location, would the 2 inches still be a recommendation or would 1 inch suffice?
The slab will be around 6 to 8 inches at most locations. Does this play into the viability of radiant heat?
The exterior walls will be metal studs have at least 6 inches of insulation and the roof will also be insulated with polyiso.
how quickly does this system dissipate the heat once it is turned off. The reason I ask there are times where the temperature may be 30 in the morning and warm up to the 60s during the day. Basically, I am worried about the system, making the building too hot.
since I am planning on putting in AC, am I better off using gas heat and a ducted system?
