No gas bill all this winter

Just opened the latest gas bill. The gas company demanded a $120 deposit when we turned on the service last year. Now, it has applied that $120, with interest, as a credit. The bill averages $10-12 a month. We heat a one-bedroom apartment with a DeLonghi Magnum electric radiant heater, so it should be next fall before another gas bill with a payable balance arrives. The electric bill, meanwhile, should jump from about $35 to $105 if it gets really cold. Last winter's highest was $90 and AEP just filed for a 14 percent hike. Not too bad.
