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.
