: : (2) Use a stainless steel heat exchanger, which transfers heat to a separate, distinct zone, complete with back up valves and such.

: : (3) Use a indirect coil (domestic coil I think it's called) which passes through the boiler and runs through the hot water zone.
well i had the same system, we had purchased a pearless boiler, this boiler have 2 steam pipe out put, the plumber connect one to the old main steam pipe, and connect the 2nd, to a new radiator
intead of the hot water zone, and it is working very good so far. that was intall last year and i found it the best, if you are interestsd i will sent you more info on how to size the new steam pipe.
