This Lehman’s heat-powered stove fan is the no-electricity, no-batteries solution to the universal woodstove problem: the area right around the stove gets hot, but the heat doesn’t move into the rest of the room without help. The fan sits on top of the stove and uses the heat differential between the stove top and ambient room air to generate electricity (via a Peltier-effect element) that drives the fan blades — no plug, no batteries, no manual operation.
Built-in temperature gauge for easier monitoring and automatic start at 140°F (60°C) — set the fan on the stove and forget it, it spins up when the stove is hot enough and stops when the stove cools. Totally quiet operation. The 60° oscillation pushes warm air throughout the room rather than fixed-direction blowing, improving overall stove efficiency by up to 15% compared to non-fan operation.
Construction is robust extruded aluminum, anodized for corrosion protection against the moisture and minor smoke that accumulates near a working woodstove. Overall 8-3/4 inches wide footprint. For off-grid households, primary-woodstove-heated homes, or anyone in a power-outage zone where stoves work but electric fans don’t, this is the perfect-fit accessory. Lehman’s catalog selection.
