Heat Pump or Gas Furnace
I live in Orlando, FL and I am considering replacing my 11 yr old Rheem system with either a Lennox XP21 or Lennox XC17 with G61V gas furnace. We have a 2 story, 6,000 sq ft house that is 125 yrs old. No insulation in the walls and original single pane glass windows. The house is on the historic registry so we will never have insulated walls or windows.
We are putting a lennox XP21 (heat pump) for the upstairs. We are leaning towards the Lennox G61V gas furnace for the downstairs for comfort. From my experience, a house like ours cannot be warmed up with a heat pump when the temps are 40 or below and 10-20mph winds. The past two winters had several weeks below 40 and windy and the old Rheem heat pumps would run 24hrs to keep the house at 60.
Any opinions on installing a heat pump vs gas furnace in my situation?
My Electric is 0.125 per KW and natural gas is 1.17 per therm.
