You didn't say what make/model your furnace is, but the quote below applies to the Atwood/hydro-flame 8500 series furnaces used in many RV's.NOTE: Furnace efficiency rating is a thermal rating determined under continuous operating conditions, independent of any installation. Efficiency rate is given at 77% minimum, actual efficiency rating may be higher.
Atwood 8500-IV Series Furnace
I am not sure what furnace I have, when the rain stops I'll go outside and see if I can find the manufactures name, 77% seems pretty good maybe all that hot air pouring out of the exhaust is a small percent of what is being delivered to the interior.
