what type of boiler?

Options
I need to replace my 1950's cast iron boiler. I have a hot water system with monoflow tees and sunrad radiators...roughly 80,000 btu of radiation. I am looking for something very efficient.
Can somebody explain the differences between condensing boilers, low mass boilers, and any other kind of high efficiency boiler, as well as any piping requirements I might need for them (I've been told that I'll need to pipe differently for these boilers, such as primary/secondary which I'm not very farmiliar with). What are the pros and cons to the different boilers?
Thanks,
Izzy

    what fuel are you using and what type of boiler are you interested in? (wallhung, spacesaver, conventional)?
