Ok had our new Rheem furnace put in last month. Had the gas and elect co run a NG line to our house then the furnace co piped about 60 ft of pipe to the furnace and fireplace.
They ran the furnace to set it up for awhile and then left. The furnace and FP are all we have on NG so we have NOT used it at all since st up.
Got the bill this month and they billed us 40 therms ! Now I looked at the meter and the dial all the way to the let reads in 100's and it is between the zero and the 1 which I would assume is like 40 or 50 but there is NO way we used that much gas !
The needle hasnt moved since they did the install so there is no leaks also the gas co checked for leaks after they turned it on.
It doesnt seem like set up would use that much.. My neighbor has gas water heater, range, dryer and he only used 19 therms for the month, we have nothing running on gas ....
