We keep the temperature around 65 degrees, our 3-Fujitsu's air source heat pumps (two 1-ton units and one 1.5 ton unit) have been able to provide us with all of our heat. -3 degrees has been the coldest temperature that I have witnessed this month. We live close to Gillette stadium where the New England Patriots play their home games in Foxboro, Massachusetts.
Our upstairs heat pump is set to 60/62 degrees, downstairs we have two heat pumps (1-ton and 1.5 ton) and the 1.5 ton is set to 70 degrees and the 1-ton is set to 62/64 degrees. 1840 square foot cape style house built in the late 1970's.
