I'm building in Central New Jersey.  Per the Weather Channel, average winter
lows are in the 20's with average highs in the 40's.

It's a standard T-hanger, metal construction with a full concrete floor.  To
create a comfortable 70 degree environment I have a 10 x 30 "tent" set up
inside.  Inside the tent I use 4 Mr. Heater propane catalytic units.  For
the area outside the tent, I have a 155K BTU Diesel turbo heater.  On the
colder days, the diesel heater runs most of the time.  On, say a 40 degree
day, it runs about half the time to keep the general area 60 - 70 degrees.
Inside the tent stays a comfy 70.

For initial warm up inside the tent I add a 55K BTU propane turbo heater.
It runs for 10-15 minutes.

CO you wonder?  After reading the recent posts, I bought one of the
suggested meters and tested.  Results were ZERO output for the diesel and 4
catalytic heaters.  The propane turbo brings the level up to 13 ppm.  It
drops to zero very quickly when the unit is off.  Believe me, there is
plenty of ventilation - the temperature drops like a rock when the heat is
turned off.

Worst days for heating - when it's windy.  Biggest draw-back - the diesel
heater is noisy.  Even on the best days, the floor doesn't get warmer than
55 degrees.
