The Valor H3 is the "problem solver" of the Horizon fireplace line. Its ultra-slim 15-inch depth allows it to be installed in shallow wall cavities or small rooms where a full-sized fireplace would be overwhelming. Despite its compact size, it does not compromise on performance, delivering up to 25,000 BTUs of steady Radiant Heat. This model is particularly popular for "Retrofit" applications, where specialized backing plates allow for lower combustible header heights (down to 33"), simplifying the replacement of old wood-burning units.

The H3 offers deep customization with three high-definition log sets—Traditional, Birch, or Driftwood—and seven interior liners including Herringbone and Reflective Glass. Like all Valor H-Series units, it is fully compatible with the HeatShift System™, ensuring that your TV or mantle stays cool while the room stays warm.
