Temps have been up and down here so far, but when down at night, enjoying the base load heat in the basement from the pellet stove here, too.
This time of year the lowest feed rate yields two days easy on 40 lbs of pine pellets and that's more than enough heat. Since we shut it down during the day, lasts longer.
Keeps the inefficient propane furnace from running.
During REALLY cold weather, both crank along, keeping up with the upstairs having some insulation challenges.
You can get the majority of the base load from the pellet stove when down around 10F or lower, but you'd have to keep that corner of the basement at 80F.
Especially with any wind. Ha.
Current propane prices have the pellet stove beating propane quite well right now, but it's nice to be dual-fuel for weird price bumps in either one.
40 lb bags of pellets were $4.50/ea this year. Propane was up around $1.90/gal here for a while. Was close to $3 during the peak quite a while back. Wood pellets haven't moved much in a couple years.
Our stove also has the ability to be hooked to a thermostat but I haven't found time to research it fully yet. Was thinking of doing a thermostat system that can treat the propane as auxiliary heat similar to a heat pump plus aux arrangement.
Unfortunately in initial searching I can't find a thermostat that can both handle the pellet stove's ability to provide two levels of heat (low feed and high feed) and a third aux heat from the propane furnace, that ALSO can be two zoned so if the upstairs is struggling the propane will be forced on. That's a tall list for even thermostats like the Nest and other fancy ones.
Meanwhile manual management of the pellet stove and leaving the upstairs thermostat for the propane set relatively low "just in case" is working fine. I just like automation, when it works.
