In my other post, I ranted and wailed about the propane industry. Since my
home is ten years old, I probably have another 3-6 years on the Goodman
propane furnace before it craps out. I want to replace it with a dual fuel
system, i.e., a heat pump for the good days with ambient above 40 or so and
kick in the propane when the HP would call for auxillary heat.
Who's got dual fuel, are you pleased with it, does this have any drawbacks I
have not yet discovered, and did you do a cost/economy analysis before and
since the install.
Of course, the region is of great importance, as is the relative cost of
electricity and propane. Here, central North Carolina, propane can be had
for ~$1.70 gallon and the sparks run $0.083/kwh.
Yes, I understand the impact of increased efficiency on a new unit (HP as
well as new propane burner), just wondering if you have determined WHEN the
increased initial cost has been offset and you start saving.
