furnace vs. boiler
I am in the planning stages of replacing an older furnace in my 3 story home. Right now it is an oil-fired furnace heating cast iron radiators.
Is there any advantage to using a boiler over a furnace? And how about whether to switch to gas vs. oil?

A boiler is what you have. A boiler heats water. A furnace heats air. It is all in the terminology.
About oil vs. gas, it depends on the local price. In my area, oil is much more expensive than gas.

Is there any advantage to using a boiler over a furnace?
- can heat people without moving air (which cools people)
- more energy efficient to transport hot water than hot air
- easier to control and zone water
- can use the boiler to heat domestic water as well
Furnace Advantages
- if it leaks, it only leaks air
- no water inside to freeze if the power fails
And how about whether to switch to gas vs. oil?
- can be cheaper
- allows use of modulating condensing boilers
- no tank (which can create insurance issues)
- easier for annual cleaning
- can use for BBQ, stove, dryer...
Fuel Oil Advantages
- can also be cheaper depending on market
- no gas line interruption risk
- can have more warning before CO posioning due to smoke
- natural gas reserves will run out before oil goes dry
