I just got my first gas bill after a full month of use on my new hi-efficiency furnace.
On the bill they put a comparison of usage from the present date and compare it to last year.
Fortunately for the sake of comparison the temp this year averaged one degree colder than last year but the usage was only 85% as much.
Not only that, since my wife hates the cold, I told her we could keep the temp, in the house a few degrees warmer at night.
I used to turn it down to 62F and now I just turn it down to 64 or 65
House is 1900 sq ft but has a basement that I keep slightly heated.
Average temp 15F
total gas charges including surcharges $210
Something I can actually afford
Got my $150 energy rebate check a few days ago
