American Ingenuity suggests that dome owners try to locate their fireplace toward the middle of the dome, rather than along the outside edge which would cause the flue to be very tall on the outside. This puts more of the flue pipe inside the house where it can radiate the heat. However if needed the fireplace can be installed on an exterior wall.
Ai can custom design the location of a wood stove or fireplace in the dome, after given general desired location, flue pipe or fire place manufacturer and model number and flue pipe outside diameter. During plans design the use of AutoCad’s three D layering allows for the location of the flue pipe to exit the dome minimum eight inches from the center of a seam.
How is the fireplace flue installed in the Ai dome? Contact Ai for a document that explains how to cut a hole in the panel, affix bolts to the dome, etc.
In the Ai Domes can I use a fireplace to heat them? Yes. Ai’s smaller sized domes (15′, 18′ and 22’) have such small heating and air-conditioning demands; it is practical to utilize a window air-conditioner and a space heater.
Bear in mind in some states, including Florida, a permanent heat source has to be shown in your building plans and installed within your dome. This means a space heater would not be acceptable. You would need at least a baseboard heater installed to comply with the permanent heat source requirement. Ask your building department if they have a permanent heat source requirement.
Can even your 45’ dome be heated with a fireplace? Yes if the heat from your fireplace is blown through your duct system to heat each of your rooms. The following Home Power magazine article discusses how the Collar’s heat their dome with a fireplace.
What do you need when you are going to live in a high desert (7,500 ft. elev.) 40 miles from the nearest town with the winters reaching down 20 degrees below zero? That is where Jim and Mary Collar planned to build their solar retirement home. To extend electric power to their home site would cost $22,000.00 so the Collars decided to produce their power using photovoltaic solar cells with a back up generator. Their primary source of heat would be their fireplace.
In 1995 after researching many alternative-building methods, they found their home, an American Ingenuity 45’’Dome House and 30’’garage. The American Ingenuity dome kit was selected for its strength, energy efficiency and its affordability. They selected sub contractors for the construction of their two domes with Mary being the general contractor. Jim was commuting 40 miles to his job but on evenings and weekends they could work together. They were asked by the state of Utah to participate in “Utahs’1998 Tour of Innovative Homes” which is in conjunction with the American Solar Energy Society’s National Tour of solar Homes.
