Well, I think I made the first "fleece thermal barrier" a few years back. Version two: http://jones.colorado.edu/VW/FleeceBarrier Such a slight layer makes a HUGE difference in the effectiveness of the Propex. I wouldn't think of NOT using it if I thought I'd kick on the Propex in the morning. I sleep in a warm bag and only turn on the furnace a while before getting up in the morning. Of course I don't use the fleece barrier if I have grandsons sleeping upstairs.... ;-) And just believe Karl's numbers on Propex propane use. I wondered last year if my tank would ever empty running the Propex and the stove. Feeling how little heat comes out the Propex exhaust indicates how efficient it is. Richard |
