My brother is looking for a stove or fireplace for a house he is designing. The layout will be a 2300 sq ft story half 1000 sq ft open loft upstairs. The living room ceiling will be 18" the rest of the house will be 10' ceiling. The stove or fireplace will be located close to the middle of the house. Originally he was looking at a Supreme Duet but I have him looking at Blaze King ultra and a Regencey F5200. He is wanting an alcove installation if a free standing stove. The main source of heat is an outside boiler but the stove would be used in the shoulder season and to cut back on fuel consumption by the boiler it also heats a 5000 sqft out building. Any other stove or fireplace recommendations?
