Hello everyone & thanks in advance!
We just built a new home with 2x6 walls, plenty of insulation, etc. Our first two natural gas bills were over $200.00 !!!! I will give as much info as possible:
-1,800 square foot ranch with basement unfinished with open stairwell
-We live in North Central Iowa
-There is no wind break whatsoever around the house and it has been a very cold & windy winter
-We rarely have the t/stat above 70 degrees and turn it down to 66 when we are gone during the weekdays
-Rheem RGRL09EZAJS furnace
-Venmar Constructo 1.5 air to air exchanger
-Only partial return air panning in basement, I assume they plan on the drywalled ceiling to take care of the rest
Gas Charge Information:
-1/9 to 2/10/09, 32 Days, Avg. Temperature 12 degrees
-254 ccf x 0.974 pressure x 1.023 BTU factor = 253 therms
-Delivery charge: 253 therms x 0.18438
-Gas supply charge: 253 therms x 0.66141
Does the air to air exchanger play a big factor in this? How do you know that it is installed & running the way it should? Thanks ahead of time for all your help. As well built as this house is, I was shocked to see gas bills like this!!
