Good question.
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.
In refineries, the terms "furnace" and "heater" are used interchangeably, sometimes with the word "fired" in front of heater.

No, each must be vented seperately.
An industrial furnace or direct fired heater, is an equipment used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty, type of fuel and method of introducing combustion air.
A furnace heats air; a boiler heats water. --The HVAC Veteran
for oil fired furnace it is 4% , n for induction billte heater it is around 1%.
"A holmes heater, generates its power source by being filled with oil; whereas, a regular furnace runs off of either a electricity or a gas power source."
Not if it was disconnected properly
if your heater just went out in your house and you need a really good electrical furnace you should really consider getting a whole new furnace from a hardware store or a heater store.
There are plenty of different manufacturers of oil for furnance heaters. Some examples are Armstrong, Carrier, Ducane, Lennox and Miller. It could be profitable to compare prices between different offers to save money.
Central heating systems usually heat on a different system from the hot water heater, unless the main heater is a combination furnace/hot water heater. If this is the case, it could be because the outflow of hot water is greater than the ability of the furnace to heat the water.

Their is no difference between an ashing furnace and a muffle furnace
Furnaces have no RPM ratings
There are different types of heating coils. Most are electric heat strips, refrigerant coils or hot water(hydronic). Your furnace\heater fan blows across the coils to heat your home or office.
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.
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.
