Now the fun part, measure blower amp draw where it is at, and at your
desired setting, , calculate run time , at present and new setting, run
your Kwh costs to reflect your increase in kwh and decrease in run time
if any. You just lost in electricity costs. For most of the US Kwh are
more expensive than NG so you are a net looser there. Oh did you
increase efficiency of the Ng side, , im sure not enought to matter or
offset the higher Kwh to run the blower. Say your blower takes 375 watts
and runs 8 hrs a day avg and cost is .125kwh, mine is, your present avg
cost is 9 kwh a day or $33.75 a month.
