I'm building a 700 square foot addition with a rather high ceiling, in Central N.J., and someone told me to heat/cool the space with a heat pump. This clever device produces heat in Winter and a.c. in Summer. I've been told that this is very economical and efficient.
I was also considering radiant floor heat for Winter and a ductless split unit ac for cooling in Summer.
My question is:
Would heat pump be sufficient for comfortable heat in Winter?
Would we have hot heads, but, cold feet with heat pump?
We have a pretty good heating season (6 months-usually) that hovers around 30 degrees on average in Winter.
Thanks in advance.
