HearthStone WFP-100: a big, clean-burning built-in wood fireplace
The WFP-100 is a large zero-clearance wood fireplace that frames into a wall like a built-in, with a blower included and up to 95,000 BTU. Add a hot air kit to send heat to other rooms.
A built-in wood fireplace
Zero-clearance fireplaces frame directly into a wall with a factory-built chimney, so you can add a real wood-burning fireplace without masonry. Finish the wall in stone, tile or wood around it.
Heat, not just ambiance
Unlike open fireplaces, the WFP series is EPA certified and built to heat, with optional kits that move warm air into other rooms.
