What size heat pump for a very small house?
I am getting different opinions on the correct sizing of a ductless mini split air-source heat pump. the mitsubishi rep recommends an 18,000 btu unit but the daiken rep thinks we can use a 12,000 btu unit. thoughts? it's for a 610 sq' house with 8' ceilings, r38 walls and r60 ceiling in -32 design temp. we will use electric baseboard heat for back-up. thanks!
