More and more, open-concept living is what people are looking for in their new homes and even in their old homes. The walls are coming down and being replaced by bright, wide-open spaces. Where do we put the heaters, you ask? The answer is the kick-space. The Kick Space Heater sneaks under kitchen cabinets, bathroom vanities and even into stair risers. Comfortable, forced-air heating from a most unexpected source.
