mini split sizing for my cottage
I am new to the site but have read many responses by Dana and it certainly sounds like you could help me.
I have a cottage outside Toronto which I live at in the summer and also go up 3-4 times in the winter.
my cottage is 760 sq ft, rectangle in shape with a cathedral ceiling. Open concept with 3 bedrooms off the main area.
I have a 14600 btu portable heat pump/AC that does not do the trick in cooling the place so I am going to put in a mini-split heat pump.
I have attached the second page of a manual J type calculation and it indicates I need an 18000 btu heat pump for cooling( which is what I am mainly concerned with although I will use in the winter as supplemental heat to my wood stove.
One contractor recommends the Fujitsu 18RLXFWH, while another recommends 15RLS3H.
Both seem to meet the requirements but I am concerned the 18K unit since it cycles down to 7000btu while the 15K unit goes down to 3000btu. I am thinking the 15K will be better to reduce humidity in the summer.
Your help or recommendations would be appreciated.
