November 7 - it's been two months to the day that the boiler was fired up. So I thought I'd give another update about the rate of pellet use and then some costing information about the whole project (not including the chickens, quad project, or pellet mill endeavors that may or may not have included overpriced imported beer).
Pellet use to date: 118 bags (2 pallets plus 18 bags)
112.8 g.e. / 30 days = 3.76 g.e. per day. (47 bags first month)
Average 46.6° F for the month. 2.1° Warmer than average.
170.4 g.e. / 31 days = 5.49 g.e. per day. (71 bags second month)
Average 15.1° F for the month. 8.4° Colder than average.
283.2 g.e. for 2 months averages 4.64 g.e. per day. (61 days or 2 months)
Ash production: About 10 gallons to date.
Costs to date:
$10,350 - One Tarm Multi-Heat 2.5 boiler
$20,314.87 - Build and basic finish the boiler house, Banty Shanty, and 'Studio'
$ 2,191.60 - 18,400 pounds of pellets (1,080 g.e.)
$ 1,700 - Insulpex pipe to transfer heat from building to building
$34,556.47 - Total
If I add in the mill (that is currently of questionable use though not yet discounted) - add another $4,000.
After the first shakedown heating season the entire heating system will get two changes - more efficient air removal equipment and a complete fluid replacement with about a 25% glycol solution. Also, the shop zone will be physically added into the loop as it was originally calculated into the load for sizing the boiler.
There are other projects associated with 'tuning' the house and heating system to be more efficient, but they're pretty typical of house maintenance. Attic insulation, window seals, outlet/switch seals, baseboard purging, door seals, house skirting, thermostats, air exchange...
