I agree with Greg that the rated BTUs on that unit would hardly make a dent even in a 13 footer unless it was well insulated and left on for a long time.
Thank you for the education.
I guess I'm the idiot for believing the experts in thinking that 50 BTU per square foot would cut it. I assumed since those #'s were for an 8' ceiling our campers would need only 75% of that because they were shorter, take off another 10% volume for benches, cabinets etc. we would be looking at about a 65% equivalency.
10 x 6 = 60 Sq ft.
60 x 0.65 = 39 sq ft equivalency
39 sq ft x 50 BTU / square = 1950 BTU
I thought that using 2/3 of the output of a unit might be efficient enough. Please excuse my faulty logic. I'll take your word for it and admit to my ignorace of Air Conditioning
. I have no idea of what is required down South, furthest I've ever been is Cape Cod.
I do know that my 3000 BTU furnace
pumps out way too much heat for my little trailer, after we warm up the trailer, I just turn it back to the pilot light
to keep the edge off.
