What's happenin' John!
Good to "see" ya!
I've got a 46' x 36' completely uninsulated barn with dirt floors that I keep at 55* when I'm working out there. I have a 125K BTU kerosene torpedo heater to warm everything up quick, then I have a 90K BTU
furnace that maintains the temp -- as long as it's not windy. Chest height might be 55* but the floor (which is usually why I'm working out there -- laying on my back) is about 30* -- lots of gaps! Even worse than my house, if you can picture that one!
Once it's up to temp, I turn off the kerosene, because,...... I guess my wife likes having me around!
But those heaters are plenty for me. You should have no problem keeping a new place warm, especially with insulation & NO GAPS!
Here is part of MY house ( the wife's house is, well, the HOUSE
) with -some-
of my toys. ............I may have a problem.....
