“You’re usually still paying the same amount for the gas. It just averages over the year or so. So come summer when you use little/no gas, you’ll still have a $340 gas bill.”
That is partially correct. The cost/therm is averaged, but I don’t use it for heat in the summer. Just cooking and hot water. For me gas is up in winter, down in summer, reverse that for electricity. I actually have saved money on this plan.
