Pellet and cook calculator

Planning numbers for time, pellet weight, and whether the hopper survives the cook. Not a promise. Wind and weather will move this.

Grill model

Camp Chef Woodwind Pro 24

Listed hopper: 22 lb
Assumed burn: 0.85 lb/hr at 225 F
Full hopper runs: 25 hr 28 min

Hopper hours use the temp and ambient you picked, not the mild 225 F catalog column.

Burn rate is a PelletDeck planning assumption, not a manufacturer lab test. Full specs for this model

Ambient condition (you pick it)

PelletDeck does not look up the weather at your address. This is a setting, and it is the one that surprises people: sub-freezing roughly doubles pellet use in this model.

Hopper size (lb)Listed hopper for this model is 22 lb. Change it if yours is different.

Planning number that tries to leave room for a stall. A 12 lb packer at 225 F is often an overnight job. What the stall does to your fuel math

Estimate

Cook time: 16 hr 30 min; 16.5 hours
Pellets: 14.4 lb; 0.85 lb/hr once running. How burn rate moves

ClearHopper covers this cook on paper

About 7.6 lb left after 16 hr 30 min. A full 22 lb hopper runs about 25 hr 28 min at this burn rate.

Still look in the hopper before you go to bed. Paper margin is not fuel.

Hopper load: 22 lb
A full hopper runs: 25 hr 28 min
Left at the end: 7.6 lb

How hopper hours are counted

The link carries these exact inputs, so whoever opens it sees the same numbers.

Assumptions

Cook time starts from 1.5 hr plus 1.25 hr per lb, then scales by (225 / target temp)^0.85.
Pellet burn starts at 0.85 lb/hr at 225 F, then scales by (target temp / 225)^1.2 and an ambient multiplier of 1x (Mild (about 60 to 80 F)).
Ambient is the setting you picked, not a live forecast. PelletDeck never looks up the weather at your address.
Startup waste is a flat 0.35 lb. Real ignition can use more if you leave the lid open.
Wind, wet pellets, a dirty fire pot, and a leaky lid are not in the math. They usually burn more, not less.
This is a planning estimate, not a promise and not food-safety advice.
