but I/we may change our heating system in teh future, as the hot air
heating system might be able to be modified such that it heats the
water (like the Johnson Starley system we had in our previous house).

So, hence I am wondering now if I can use an indirect tank, thus
allowing for future changes to the system.

That's a somewhat different angle to your original question. The
answer is yes, the coil will simply remain unused.

If you are thinking ahead then how about installing a solar
cylinder? These have an extra coil for solar water heating and
better insulation levels.
