Can I hear some methods I might use? Background: Single family dwelling, natural gas unit is very new (so I'm not removing it), price of natural gas is very high here and I'll soon have solar panels.

to approach the SAME cost for electric as NG condensing boiler, with a therm @ $1.90, you need $0.08/kWh electric. can you get your average that low, even with solar? that's a tall order. if you're doing it with some kind of AtW heat pump, you'd have much better luck.
