The newer units have a thermostat. Mu son in law's parents live in Danbury, CT. and burn 3 - 5 tons a year. Their stove doesn't have a thermostat and he needs to adjust the feed rate according to the outside temps.Not a Harman but was gifted a pellet stove by my grandfather-in-law. Put it in our house and have been amazed how well it does heating the whole house, 1,400 sq. ft. It is an older model so there isn't a ton of adjustment. It seems like it is on hot or on really hot lol. The room it is in is a little warm but the rest of the house is perfect. Kind of want to put one in at camp now. Have a propane fireplace at the moment.
I bough a ton for $215 in Erie this year from my local Harmon dealer. That was in November. Seems like it goes up ~$10 each month in the winter then drops over the summer. Not sure the cheapest they get but am going to check it out next year. Hard part is finding a spot to store a ton of pellets for months...Pellets used to run around $200 a ton here last I looked, but that was a few years ago. What are they up to now?
The little Allure 50 heats my 1400 sq ft house. with permit, installation and the stove I spent $5400.00. The electric cost of a cold winter with the heat pump was over $3k a year. I think I will come out ahead.I looked at the allure50 but we needed the fireplace insert and really like the accentra 52, it’s heating our whole cabin but we have cathedral ceilings as well. Works nice. I considered propane but I was able to get pellets through a friend for 100$ a ton.
