Frequently Asked Questions
Q: What is a TEG power module and how does it work in a stove fan?
A: A TEG (Thermoelectric Generator) power module uses the Seebeck effect — it converts the temperature difference between the hot base of your wood stove and the cooler top of the fan into a small electric current. This current drives the fan motor, circulating warm air around the room without any batteries or plug-in power. The Bismuth Telluride material in this module is highly efficient at this energy conversion.
Q: How do I know if this replacement module will fit my stove fan?
A: Please check the dimensions of your existing TEG module and compare them to this product's listed size before purchasing. Most standard heat-powered stove fans use similar TEG sheet sizes, but we recommend measuring your current module or checking your fan's model specifications to confirm compatibility.
Q: What temperature range is this TEG module rated for?
A: This module is heat-resistant and rated for operating temperatures up to 200°C or 250°C (depending on the variant), making it suitable for use on wood-burning stoves and fireplace surrounds. Always ensure the module is installed correctly to avoid exceeding its maximum rated temperature.
Q: Is this module easy to install at home?
A: Yes — replacing a TEG module is a straightforward DIY repair. You will typically need to open the fan housing, remove the old module, and attach the new one to the heat plate. Basic hand tools are sufficient. We recommend consulting your stove fan's manual or a how-to guide for your specific model before beginning.
