Where stove heat goes — and where a sensor survives

We simulate the air-temperature field above a six-burner gas range at the standard 30-inch range-hood height and ambient 25 °C (77 °F). The question: how hot does the air get where a stove sensor would sit, and does mounting position matter? It does. Heat rises in a plume that is hottest in the centre under the hood and cooler off to the side — so a sensor under the hood overheats, while one on the hood’s cool side stays within its limit in every case — the recommended mounting position.

That is why Stovyn mounts on the range hood’s cool side, off the rising plume — close enough to catch a dangerous temperature rise early, clear of the worst heat. Step through the cases in the interactive simulation below (burners and hot oil, fan off and on), and switch between °C/°F and in/cm.

Air temperature the electronics reach

Device-safe limit 70 °C (158 °F) · electronics fail ≈ 85 °C (185 °F) · ambient 25 °C (77 °F). Thermal simulation at a 30-inch hood height; figures are modelled estimates pending bench calibration.

How the simulation works

A buoyant-plume model computes the air temperature at every point above the cooktop: hottest at the burner surface, decaying as it rises and spreads. The vent fan draws the plume up into the hood, lowering the air temperature the sensor experiences. The colour scale runs from ambient (blue) to the fire range (red); the contour line marks the 70 °C (158 °F) device-safe limit. Final figures will be calibrated to Stovyn bench runs.
