Thanks for the explanations guys.

My bet is that natural gas prices will continue to be low for the next decade or so. Furthermore, we all know out here that BC electricity rates are climbing dramatically:

BC Hydro's proposed rate increase:

Year 1: 9 per cent (April 01, 2015)
Year 2: 6 per cent
Year 3: 4 per cent
Year 4: 3.5 per cent
Year 5: 3 per cent
Note: Each year's increase is a percentage of the previous year's rates. So, this compounds to +28% increase by 2019.

Therefore, I think that I'm staying with a HE Natural Gas Furnace & a HE Central Air Unit. I don't think that there is any advantage of a Heat Pump to me...
