Fan speed wood stove cooking becomes much easier when two positions on the dial already mean something to you. Before the pan is hot and dinner gets busy, learn where roughly 20% and 80% sit on the Hillrein Zhengtu controller. Those are not rigid recipes. They are useful reference points: one for calm finishing heat and one for strong cooking heat.
The habit sounds small, but it prevents the most common kind of wood-fire confusion. Instead of turning the knob at random, adding wood at the same time, and then wondering which change worked, you can return to a known airflow range and let the pot answer.
Why fan speed wood stove cooking needs reference points
A dial without landmarks invites constant correction. A cook sees the flame shift, turns the fan, adds another stick, and moves the pan—all within ten seconds. The stove never gets time to respond, so heat control feels less predictable than it really is.
Before lighting, look at the controller and identify a low reference near 20% and a high reference near 80%. If the knob has no detailed scale, use its angle and a fixed feature on the controller housing as visual landmarks. Do not add permanent markings that could damage the controller; a removable note on your prep table is enough while you learn.
Start below the high-heat reference
Prepare dry small wood around 10 cm long. Build a loose first load with room for air, light it, and use low to medium fan support while the flame establishes itself. Do not begin at the 80% reference simply because the meal will eventually need high heat. A cold chamber and an overdriven first flame can make startup messy.
Let the chamber warm, watch the small wood catch cleanly, and increase fan gradually. Visible smoke should fall as dry fuel, temperature, and airflow stabilize. Startup and refueling can still create smoke, so use Zhengtu outdoors or in another properly ventilated, local-code-compliant setting.
Use the 80% reference for the work that needs it
For stir-frying or fast pan cooking, build a fuller working wood load before the critical cooking stage and move toward the high reference near 80%. This is usually the practical sweet spot for strong heat without spending wood as quickly as continuous maximum fan.
The stove can run at 100%, but that is an extra push, not the everyday destination of the knob. Use it only when the pot genuinely needs more recovery. On Zhengtu, higher airflow can make the visible flame look lower while heat under the cookware becomes stronger. The annular oxygen intake concentrates combustion around the hot zone, so judge the setting by the sizzle, boil, and pan recovery—not flame height alone.
Return toward 20% for the quiet half of dinner
Soup, porridge, rice finishing, and covered simmering need a different rhythm. Once the pot is hot, reduce the active fuel load to one or two short dry pieces and move toward the low reference near 20%. Give the pot a little time before making another change.
If a healthy ember bed remains but the simmer weakens, nudge the fan upward first. If the pot is boiling too hard, wait after turning down instead of immediately removing fuel or shifting the cookware. One change at a time makes the two reference points genuinely useful.
Match wood load to the dial
The fan cannot create heat from an empty chamber, and a low dial cannot instantly calm an oversized fresh load. Pair the 80% reference with a fuller load for wok work. Pair the 20% reference with one to two short pieces for slow cooking. That relationship matters more than memorizing an exact knob angle.
In suitable steady use, Zhengtu can consume less than about 1 kg, or 2 jin, of dry wood per hour. Fuel dryness, wind, cookware, airflow, and cooking style all change the result. Reference points help efficiency because they reduce accidental time at maximum airflow and unnecessary refueling.
Build repeatability into a live fire
The Hillrein Zhengtu stove is a fan-assisted wood gasifier cooker for real meals, not a single-speed flame display. Its dial is most useful when it becomes part of a repeatable cooking routine.
Learn two positions, warm the chamber before turning up, and change either fuel or fan before changing both. After a few meals, “low” and “high” stop being guesses. They become familiar places you can return to while the food—not the fire—gets most of your attention.
