wash gas bill of 470$ for a 66 degree home with new windows

[Anonymous]

I have a 5000sf house with gas radiant/stove/hot water. the actual meter reading from 12/20-1/23 was 98CCF, or $166. We do not have budget billing. we are in a 100 year old townhouse, but with a new roof and new windows.

we have 5 separate heating zones, keep the public spaces at 72 during the day and let them float down to 64 at night or when not used.

OP -should- look at their bill and previous bills to see if the reading type changed from estimated to actual at any point, which is one way the cost could jump a lot. they should also look carefully at the gas meter to see if the meter number, and reading matches up with what is outlined on their bill. In my previous home they had the meters mis-assigned. A FLIR, if you can find/burrow one, can help you identify heat leaks. Finally, yes, would be good to actually record the runtime of your boiler and water heater for most of a day if possible.
