Its a whole lot of trial and error i do understand that. This is what i heat my 3,000sq ft shop with everyday.. its a monster 4ft deep 2ft wide and 3ft tall burn chamber... so cutting the heat back and going home to 64/65 degrees just doesnt cut it. I like heat.. i must be getting old :-/View attachment 167892

That thing looks like a dungeon!

I won't post a photo of the coal furnace I built in the late 70's, you guys would wonder why this guy isn't committed ! Fortunately it was short lived as was my boiler conversion to coal, as Carter went out of office and took his phony oil crisis with him.
 
We have been averaging about ½ bag per day over the past few days due to overnight temperatures dropping into the lower 20’s. My stove has 2 thermostat modes, t-stat and smartstat. T-stat will cycle the stove high when heat is needed and low when it is not but never actually shut the stove off. Smartstat works just like t-stat except the stove shuts off after an hour of running on low. The stove then turns back on when heat is needed. I typically run in smartstat mode during the day and t-stat at night. When we start getting consistant sub-freezing temperatures durning the day, I’ll run on t-stat 24/7 while only shutting the stove off for cleanings.
20lbs/day for a primary heat source? That's about 7000btu/hr..... What are you heating with only 7000 btu/hr? A bedroom? :)

We heat our main floor which is about 1800 sqft in size. During the day when we aren’t home, we set the thermostat to 65, it’s set to 68 when we are home. We keep our oil furnace thermostat set to 60 so if the pellet stove fails while were out, the oil furnace will take over.
 
That monster has been burning strictly pine and cedar for the past 12 years or so. Only heat in my building and need to keep the machines comfy :-)
 
wow....my house must be a pig. Approx 25F overnight - mid 30's in the day we burn 2 bags easy. When it starts going single digits we will go through 3 a day easily if not more.

Your house must either be huge or poorly insulated. I average about 1 bag a day over the course of the entire winter. It has to drop below zero for my stove to consume 2 bags per day.
 
I'm averaging just under hours per day at 120k btu for 3700 Sqft plus DHW with my pellet boiler. Guessing about 2 bags and will cap out between 5-6 bags per day in Jan.
 
*7 hours per day currently

Even if heating oil prices were to double from their current rates, it would still be cheaper than pellets to heat my house at 5 bags per day.

Small house? My break even in about $1.86 and I can fill up at $2.05. Still saving money and supporting a local business trying to get the mill up and going. No brainier.
 
I can only get about 30 hours out of a bag running it as low as it will possibly run. I have the old style knob board, on the back of the board i can turn down the auger run and pause time, i have it set to burn 3/4 pound per hour so i get about 50 hours per bag on low.
 
So essentially you are all able to heat youre entire houses with plug in electric heater on high??
 
As of now I go thru 1.5 bags.. Seems like a lot and we didn't even get into the middle of winter... Or could be due to my probe low to the ground which is thinking it's colder than it actually is.

1. Is this your primary heat source?
2. What temp do you keep it at?
 
1. Primary heat source is oil but we keep the thermostat turned down so it never actually turns on.
2. Pellet stove thermostat set to 69 when we're home, 65 when we're away.
 
Those of you still heating with pellets alone. How much are you you using a day right now? I know its going to vary alot depending on location..
Are you on a thermostat or just running off the boards?

I am guesstimating because I top mine off all the time but I would say I am going through maybe almost a bag a day. Temps in the high twenties, low thirties at night. Maybe 45-55 during the day. I have a 879 square foot house, two floors. Everyone is probably going to break out in a sweat but I like the house 75 or over...except my bedroom that I like cold. I have no insulation at all....someday maybe I will. Right now I have it set between 19 and 20 degrees celsius because I haven't figured out how to change it to farenheit...lol....which I think is about 66 or 67 however it keeps the living room over 75 and the rest of the house is probably 71 or 72. I have the blower set on 1 but can go up to 5...I had it up to 3 once so far.
 
I've been using half a bag to 2 bags a day for the past month and a half or so -- on the high end the last week or so when overnight temps have been in the low 20s. That's with a pellet insert in the living room fireplace -- the (oil) thermostat is actually across the hall in the dining room, and it has gotten up to 81 (yep!!), which means the living room was mid-80s. (My cats were very happy. :)) I have a lot of pellets stored in my garage (bought in spring '14) so I have been generous with them and have left the insert on manual, which means the fire doesn't ever go out (except when I shut down the insert for cleaning).

I haven't used ANY oil yet this season, although I have two 275-gallon tanks in the basement and they are both full (bought when oil was $2.39/gallon in my neck of the woods -- which SEEMED like a great price, but today's price is $1.88!). I usually use oil only when temps get into the teens or below, and then usually only at night, so I likely won't be firing up the oil furnace for another few weeks.

The insert heats most of the downstairs rooms fine, and a LOT of heat gets upstairs too -- the stairs are right outside the 5' opening from the living room (typical Colonial-style house), which works out well. I actually like a cold bedroom for sleeping (as in, about 55 degrees), and sometimes the bedrooms are TOO warm just from the heat rising from downstairs. Nice problem to have. :)
 
Try running it in manual mode with a consistent burn. Start low, then turn it up slowly after each hour, and monitor the heat coming from the stove. Pick up a wood stove magnetic thermometer and put it at the hottest spot on the stove. Then monitor the surface temperatures on each heat setting.

I didnt pick up a thermometer yet and outside temps held 40 overnite. I ran the stove on manual 5 - 9 since 4pm yesterday. 76 in the stove room. For the hell of it i just slid a meat thermometer in one of the exchange tubes while the blower is on and temp is only 130 degrees. Maymbe santa will get me an infra red thermometer for xmas.. but anyways, i think i will need to mix these pellets with my good stuff in order to get any heat out them. I havnt read up on anything about temp readings yet so not sure what to expect.. but i did expect it to be alot hotter..
 
130* is pretty low. I can vary the distribution air temperature from 175-250* on my particular stove.

I am blaming that totally on these pellets im trying to burn up and get rid of but still have about 30 bags or so. The penningtons from walmart that everybody seems to hate with a passion gave alot more heat and burnt much better than these with the 4 bags i tried earlier. i have good softwood pellets sitting in the shed waiting that burn amazing. I knew these didnt burn as hot as the others which is why i set it on 5 yesterday but still expected much more heat than im getting.. oh well lesson learned on this brand.. wont get into that here again.

Another rather large difference in fuel usage, is the desired inside comfort level. Over the years of experimenting with temperature algorithms and theory, I have found an amazing difference in what it takes in cost and fuel itself to maintain inside temperatures to higher differentials than the outside temperatures. One year, with propane, I used 100 gallons (about $329.00 at the time) LESS propane keeping the inside temperature at 67 VS 69*. Once you get used to 67*, it's really not bad. It came out to about a 15% less fuel cost per 5 month heating season for a mere 2* difference in comfort level. I am shocked that many keep their homes at 72-75*F. We both feel a tad too warm if the thermostat starts heading above 69*...

The single biggest factor is the setting of your thermostat. A lower temperature means less heat trying to
flow out of your house. Yes, it takes some getting use to. But wearing sweaters and layers indoors will provide comfort
at a lower thermostat setting. I heat the main areas of my house to about 60 degrees, keep my bedroom in the 40's.
Your body gets use to it; a bigger appetite. Even going out side, not such a big change, not such a big temperature
difference.
