I have 2 Hitzer 503's one is on the main level the other in the finished basement/lower level. There is an upper level where the bedrooms are. The main level Hitzer is getting serviced twice a day and I am adding about a bag twice a day. The lower level is running at a lower temperature and I am servicing once daily adding about one bag. So 120 pounds per day to heat a 1982 house that is around 3.000 square feet. Outdoor temperatures have been in the single digits at night and well below 30 during the day.

Those 503s are sweet little stoves.. I wish I could run mine lol.. I've been using 80+ pounds a day in the Axe lately with this few day stretch of coldness.. we even hit -13 a couple nights ago. The last time it got that cold was 3 years ago.

For the temps and square footage I think your 120 pounds is pretty fair :)

I'm heating 2400 which includes the basement being heated by standby loss..

I’m going through 70-80 pounds a day right now heating 2400 sq ft (1200 above grade 1200 below). No wall insulation, minimal roof insulation (4”) basement partially finished. Hitzer 50-93. Not super cold in SE Penna. though. Coolest weather was around 5 above at night and 24 during the day. I burned about 6 pieces of firewood in the wood stove in the morning to help the coal stove catch back up to 70-71 in the house on the coldest day.

I am still at 100-120lbs per day. Sometimes I hit a point where it's cold outside and the house doesn't want to get any warmer.

An example is 2F outside and windy. House is happy at 70F and boiler cycles as needed. But set tstat at 72F and the boiler and zone will run constantly.

I could turn up the triple aquastat and fire high and hot, but that eats more coal.

Incentive to continue the insulation projects and sealing up of this old house. I think I can either keep or lower my coal usage and get a few more "comfort degrees" as I complete the house's insulation envelope.

I was in the same situation last weekend when it was -20 here. House was maintaining 70 with most zones running nonstop. I could have bumped boiler up to 180 degrees but decided just to leave it alone. After a few hours of morning sun and some cooking the house leveled out at 72.

This is my first winter heating with coal. I originally bought my Harman Mark I as a replacement for an old 70s airtight wood stove because I am tired of cutting and splitting firewood. Traditionally I have only burned on the weekends, during emergencies, or when I want to work in my integral basement garage as I can leave the man door into the basement open and let warm air coming off the stove heat the garage. My house has a late model forced air natural gas furnace for primary heat. I got hooked on burning coal from the first fire in October. Since January 1st my Harman mark I has not stopped and the furnace has not turned on. I am heating an 1100 square foot early 50s brick ranch house in Southwestern Pennsylvania with full basement and integral 1 car garage. The exterior walls have all been opened up and R13 fiberglass batts installed in the early 90s. Also the windows are good quality early to mid 90s double pane. The attic has blown in cellulose between ceiling joists and R19 fiberglass batt blankets laid over the whole attic. I am tending stove twice a day and using 1 and a half (2.5 or 3 gallon?) coal hods per day of coal. I bought my coal in bulk but had purchased a few bags early on. I'm guessing about 2/3 of a bag per day. Basement is 85-90 degrees and the upstairs is 73 degrees and it feels it. With the forced air furnace the thermostat was set on 72 but the house felt 65. Certainly more involved with coal heating as opposed to setting and forgetting my gas furnace but the comfort of the the radiant heat from coal is unmatched.

For January so far, I am averaging 51pounds per day of Blaschak nut.
House is 2000 sqf over 2 storeys. One side of house is 150 YO leaky, uninsulated workmans house on a 200 YO rubble foundation. Other side is 10 YO with PERSIST insulation system and gets it's warmth from the leaky old side.

Overall, house is heated by a Heartland Oval range in the kitchen.
