Same issue here, checked my gas bill today and find out I have been charged TRIPLE, for using the same thing the last 9 months, same thing everyday. I'm responsible for the increase in electricity bill, which has an increase of 50$, due to using heater for living room area, and that's it! We even paid for a good Eco-Panel Heater 400w (200$) and it should do the job 6 hrs evening heating everyday for less than extra 52cent extra, per day.But nothing changes in the way of using gas! just the bill ...
