Propane Heat Usage Rate

[bncinwv]

After a recent post regarding using a 30 pound bottle of propane faster than expected, primarily being used for the furnace, I thought it would make for an informative topic to once again visit this topic from the aspect of what the various MOC members do to slow down the consumption rate. Of course, electric heaters help and this has been well documented over the years. We have been camping with temperatures in the mid 20's at night for five nights now and can report the following usage rates and how we obtained it. We are using two ceramic 1500 watt heaters at present, one in the front of the rig and one in the rear. Both of these heaters are thermostatically controlled and are set for 75 degrees. We have the furnace thermostat set at 73 degrees and it seems the furnace is cycling somewhat regularly since the electric heaters will not heat the entire rig at these low temperatures. When the furnace does kick on, it seems to only stay on for about 5-10 minutes at a time. While I realize that our thermostat settings are most likely higher than most will use, the reason is that I have a very cold-blooded wife (for example out S&B thermostats are set at 77 degrees!). Using this methodology, I checked the propane usage this morning and we have yet to empty one of our 40 pound bottles (that is not a type, we have dual 40 pound tanks). Looks like switchover will happen tonight though, so by my simple math this gives us a usage rate of a little less than 2 gallons per day/night period which I believe is pretty good for the conditions we are in. We are not using propane for the hot water or fridge but are cooking with it as well. As always this post is merely an informative one and if others have different results it may be interesting hearing them for the forum's general knowledge.
