Are there any efficient high btu LP stoves? Looking online at different brands and finding the efficiencies is difficult on some of the websites. I just built a 1200 sq ft cabin on piers insulated with mineral wool and now that I'm getting older wood and pellets are less likely candidates especially since I plan on travelling a few days at a time. After this winter mini splits weren't worth a darn.
 
Most of the gas burning units that I’m familiar with all have an efficiency rating in the low to mid 70 percentile, as are most pellet stoves. The reason for the ratings being in this range is due to the fact that some heat is always lost thru the vent pipes, or chimney. You can get “vent-free” or more accurately “household-vented” appliances up into the higher 90 percentile, as EVERY byproduct of the combustion process - heat, water vapor & carbon monoxide - remain in your home. The highest-rated gas appliances are rated in the 40K BTU range, which can be only 50% of what you can get from burning wood in an airtight appliance. That being said, 40K BTU - at 75% efficiency (30K) - MIGHT be enough to heat your space. Hope this helps…
