Strongly recommend the gas water heater supplied by the tankless coil. If
you (or the local codes) decide not to install it yourself, you'll still do
better with a professional install of a gas heater than the other two
solutions. And you save lots but not having to fire up your boiler in the
non-heating season. If you feed the heater from the tankless coil you will
save a lot of gas. Our gas bill tripled during the summer when the boiler
(hot water, not steam) was not running. Also since your boiler is almost 30
years old, you might need/want to replace it in the next decade. When you
do, you could save a lot by getting a new boiler without a tankless coil
(especially if you choose gas heat) and the gas hot water heater would fit
right into that setup.

1. Get rid of kids.
2. Insulate hot water lines. You'd be amazed at how much a difference
this can make.
3. Regular gas water heater.
