To me the regency h2100 sounds exactly what I want/need , only problem is it's firebox size. Is there any reason nobody else has made an insert that portrudes that far our onto a hearth? I would love a monster firebox insert with the same setup as the regency h2100. Anyone think the h2100 could heat 1700 sq ft with 25ft cathedral ceilinga? The idea of radiant/blower heat and low profile seem perfect for those who can't or don't want a freestanding infront of a fireplace opening. Let's see what u guys think
