Does the ecofan work on a fireplace?

Yes, an Ecofan can work on a fireplace, specifically on a wood-burning stove or fireplace insert. It uses the heat generated by the fire to power its thermoelectric fan, which circulates warm air throughout the room, improving heating efficiency. However, it's important to ensure that the Ecofan is placed on a flat, stable surface and that it operates within the manufacturer’s recommended temperature range. Always follow safety guidelines and manufacturer instructions for optimal performance.
