Hi all,
I'm a cold weather RV'er and wanted to test the limits of what temperature differential I could maintain with 8000 btu's (about 2350 watts fan based heaters), between outdoors and inside the RV.
The RV is a Class C 28'5" Kustom Koach with enclosed tanks, and dual pane windows. Three vent cushions are in use but there is a skylight over the shower--and another one in the main living area.
The delta T, with 8000 btu's of electric heaters, between outside and inside the RV appears to be 20C (or 38 F). For example at 7 pm it was -7C outside and the temperature inside the RV was 13C. At midnight it was -8C outside and inside was 12C.
