++++ The water will be at higher pressure than the steam. Doesn't that increase the likelihood of a leak?
Yes. You take your chances.
: : : What has to be done to clean the radiators out?
I think you are saying a good blast of compressed air is just as good.
++ Rethink; a blast of water is safer than a blast of compressed air.

: ++++ Hmm, so the heat mass is the extra water itself. The buffer tank acts to preheat and store the boiler heated water where the boiler is actually just a water heater. Can that make enough 215 ballpark water?
++ Depends on the make and model. The new Burnham, Peerless Pinnacle, Trinity, and others are basically the same idea.
Why would anyone use a traditional boiler?
++ Tradition dies hard when cast iron is a less expensive material than steel or copper. Some plumbers only know what their father told them. Learning new techniques takes investment. Eventually, the European boilers built with over 94% AFUE for both gas and oil become attractive as fuel costs go up and condensing makes sense.
