New System Energy Efficient or is old one better?
I'm looking at replacing my old Trane TUD100C948B1 Trane furnace with a Bryant Evolution 986TB60080V21. When I look at the specs on the old Trane it states 9.8 amps. The new energy efficient Bryant has the following in the manual:
Max input amps: 13.6
Unit ampacity: 17.9
Min Wire size:12
Max Fuse: 20 amp
Based on these numbers it appears I will have to replace my current 14-2 15 amp breaker with a 20 amp breaker and 12-2 wire. Isn't this system going to cost more to run for electricity? Understand gas cost will decrease but I'm focused on the electric side and what my true savings will really be?
