Do heat loss calc....

Here is my house heat loss:
Floor 45%
Walls 36%
Roof 3%
Glass 16%
Doors ~0.4%

What would my savings be if I replace standard windows with LowE?

Probably $1 - 2 on every $100 spent on heating....

Before replacing windows see if savings are there...


Also price of gas of our GasCo went up 36%....

Last november heating degree days were 369 @Indy
This november: 493

Your bill doubled? Possible...
