I was just browsing Northern and had bookmarked this heater for a potential house/shop I was thinking of buying.
I was wondering what your ceiling height was and how long between heat cycles?
The potential shop is close to your size but has 14' ceiling height and wasn't sure if I should look at something bigger?
