The Classic WarmHearth is a built in wood-burning fireplace, not a fireplace insert. This is the best option for new construction where it is desirable to have a wood fireplace that actually generates heat for the rest of the house rather than being, as with most wood fireplaces, heat losers. This fireplace has a DEQ efficiency of over 70% and can heat a home of up to 2000 sq. ft while generating 70,000 BTU. The non-catalytic WarmHearth is over 90% cleaner burning than a conventional fireplace, sending most of the heat directly into the room. With the optional Central Heat blower system (diagramed below) this stove can heat rooms throughout your home. As with all the products we carry, there are many optional looks you can achieve with this fireplace by selecting different trim options and colors.
