Have a new Bryant Furnace 355AAV042060 with the evolution control In our home in Minnesota. The furnace was installed just shy of three months ago. We were aliitle disappointed in our December gas bill in that it didn't show usage going done much from our previous furnace, a 1990 Lennox G16 (80% efficiency at best).
I am hoping the pros (and others) here can evaluate the furnace's performance. Also, your comments on how we are using the furnace, and how that maybe why we are not realizing the expected efficiency gains would also be appreciated.
We have used the following setback schedule:
72 degrees (5:45 am to 7:45 am)
63 degrees (7:45 am to 4:45 pm}
72 degrees (4:45 pm to 10:45 pm)
65 degrees (10:45 pm to 5:45 am)
Here is the run cycle data:
Low Heat: 1107
High Heat: 132
Run times hours:
Low Cycle: 466
High Cycle: 238
What do you think? Is this performance typical? Are we losing efficiency by using to large of setbacks? Any other thoughts?
Thanks for your input.
