Will a Fujitsu RLS3H Ductless Mini Split Heat Pump be enough?
I have been struggling about what type of heating system to put in our home. Ever since I read about the Fujitsu and its 33 Seer efficient system, I have wanted to install 2 in our home, one up and one down. Our home was built originally as a mountain summer cabin with baseboard heating and no duct work. It is in Western North Carolina, elevation 3600 feet.
The first floor is a finished basement made of 8 inch concrete block built on a poured concrete slab foundation that is semi earth-beamed on 2 sides with natural stone veneer on the above ground walls that was quarried locally.
The main room in the center of the downstairs is the Den with a fireplace insert which we use when the power is out. The Den is 376 sq ft which includes a small bath at one end of the room. A 144 sq ft bedroom room is adjacent to the den off the left side as well as a 96 sq ft laundry room adjacent to the den off the left side.
A 225 sq ft bedroom is adjacent to the den off the right side. If I put a Fujitsu RLS3H Ductless Mini Split Heat Pump in the Den, will that be enough if we keep the bedroom doors open (standard size bedroom doors)? If so what size?
The upstairs is stick built, 4 inch walls on half the house and 6 inch walls on the rest with added blown in insulation in the attic and a new metal roof. (built in 2 phases) The main room is the living/dining/kitchen at 668 sq ft. All together that space, including a 168 sq ft foyer is 836 sq ft. (the foyer is open to the living room with 6 foot french doors. It can be closed off from the main living area when an away room is needed) A 156 sq ft bedroom is adjacent to the living room. It has a private 5 x 7 bath. Another 5×5 half bath is off the living room. Can I put a Fujitsu RLS3H Ductless Mini Split Heat Pump in the living/kitchen and if so what size?
The entire house has a total square feet of 2144 including closets, stairs and all.
Any and all help would be greatly appreciated. Thank you so much.
