Pellets for 3,000 sq ft, by climate
Pellets as the only heat, average insulation, a typical 80% stove and pellets of about 8,200 BTU a pound. Bags are 40 lb, and the cost is at $7 a bag.
| Climate | 40 lb bags | Tons | Bags a day | Cost |
|---|---|---|---|---|
| Mild (15 kBTU per sq ft) | 172 | 3.4 | 1.1 | $1,204 |
| Moderate (30 kBTU per sq ft) | 343 | 6.9 | 2.3 | $2,401 |
| Cold (45 kBTU per sq ft) | 515 | 10.3 | 3.4 | $3,605 |
| Very cold (60 kBTU per sq ft) | 686 | 13.7 | 4.6 | $4,802 |

| Poor or drafty | 429 | 215 |
Can one pellet stove heat 3,000 sq ft?
Spread over a 150-day season, 3,000 sq ft in a moderate climate needs an average of about 25,000 BTU an hour from the stove, and about 37,500 in a cold climate. The coldest nights need a good deal more than the average, and one stove also has to move its heat through the whole floor plan.
In a house this size a single stove usually heats the main living area while a furnace or a second heater covers the far rooms. Compare the stove's rated output with a heat-load figure from the furnace size calculator before you rely on it alone. If it does heat everything, plan for 7 pallets of pellets and the dry space to keep them.
These are planning estimates: the climate and insulation figures are rough values, and a stove burns more in a cold snap than on an average day. Buy a little extra and keep the bags dry and off the floor. For wood heat, see how much firewood to heat a 3,000 sq ft house.
