gas H20

are more expensive to start with and also to switch out as you need a gas fitter or someone qualified.
electric heaters are cheaper to buy, by a few hundred and if your handy you can switch out your own once set up.
but electric is more expensive to operate and with electric rates going up it will get more expensive.
look to the future, if your planning on an upgrade to your older furnace, maybe it would make sense to get a Hi Eff gas water tank, then when you switch out the furnace to a hi eff you can close off the chimney.
I would get a couple of plumbers in to get their opinion on your set up for the future, and compare costs
try Hydros web site they have an estimate of operating and replacement costs for furnaces and water heaters that will give you an idea.
