Good point.
I live in a duplex - one side is my office. The gas company charges, as I recall, about $11.00/month just to be connected. I don't begrudge them that - they have to read the meter, send out a bill, keep records - as overhead.
With about two hours work and a bit of pipe, I connected both halves of the duplex to the same meter. It wasn't hard; the two water heaters sat on opposite sides of a common wall. Simply poking a hole in the wall and joining the gas supply lines together was relatively easy.
A call to the gas company to drop service one one side of the duplex resulted in a savings of over $100/year.
Wait, there's more!
The remaining meter is the one servicing the "office" side of the duplex and the bill is paid by a company check.
Deductible.
