Hi, I’m new to this forum and as of this fall new to pellet stoves. We bought a pelpro pp130 as a backup heat source if something was to go wrong with our primary heat which is a propane gas boiler. I know this is a low end unit but figured it would be fine for what we need it for. Since we’ve only had it a couple months only time will tell how it will hold up but so far I am amazed about its performance! Although we bought it for back up we have been using it as our primary heat for a while to see how it would do in our sub zero weather in our 1700 sqft house. I loaded it over 72 hrs ago and it is still going! Over 72 hours on 130# of hardwood pellets. We live in northern Minnesota where temps have been -2 to -37 during this time. First level has been around 73* upper level around 68*. I do run the boiler for about 15 minutes twice a day to keep floors from being really cold but that’s it. Just thought I would share as I’ve found this site to be very helpful!
