What were the heating degree days last year vs this year?
I have not yet checked that but I plan on it hopefully this weekend.
However I do know that last year even in the coldest day of the year my
system
never cycled on 1 minute after it turned off.

Yesterday the high was 45 and the low was 31.


How are you measuring gas usage, the billed cost or measured amount of gas??
Measured amount of gas.
