Last years heat did my wife in. Have a cape, bedrooms upstairs. We had a 5 unit mini split heat pump system put in this spring. Will give heat down to 4 degrees. We put a unit in each bedroom upstairs (3), and 2 downstairs in common rooms. Went with the units in each bedroom for resale value if we sell in 10 years as some people close their doors at night. Since we have electric heat it should help quite a bit on that bill. $11,000
