A furnace is a enclosure in which energy in non thermal form (e.g. a fuel) is converted into heat. The inside of the enclosure becomes an intensely hot place.
A heater is an apparatus that heats or provides heat.

It could have any size heating furnace, the two are unrelated except for the size blower used in the furnace to support the 3 ton cooling system. But the fact remains you can get a 3 ton blower in 50,000 btu furnace, a 100,00 btu furnace and anything in between.
A furnace water heater combo can save space, reduce energy costs, and provide efficient heating and hot water for your home.
Yes you can do that. I had an oil fired furnace that also heated the hot water in a coil inside the furnace. I got an electric hot water heater and had a plumber disconnect the coil in the furnace and hook up the electric hot water heater. No problems after four years.
If your furnace is less then 50000btus then yes.
An A/C unit is not required to run a furnace. You will want to make sure there are no gaps or missing equipment.
