System 2000 can be difficult to work on without special training, and has a
higher frequency of repair than many other boilers. They're not worth the
extra money or aggravation. IMO, there's no better system on the market
today than the New Yorker FR-HGS boiler
http://www.newyorkerboiler.com/frhgs.cfm combined with an indirect water
heater like the Amtrol BoilerMate http://www.amtrol.com/boilermate.htm The
FR-HGS is a 3 pass, horizontal tube boiler that's easy to clean and simple
to work on. The basic design has been around since the 1960s. New Yorker
Steel Boiler Co. is owned by Burnham Corp.

I posted awhile back about boilers. I'm still trying to make up my
mind. I am hearing a lot about 3 pass boilers. They are slightly more
efficient and are said to stay that way b/c they are easier to clean.
Are they really a lot better than conventional cast iron boilers? How
long have US manufacturers been making them? Is it really that hard to
keep a conventional boiler clean if you service it regularly or is this
a marketing thing? System 2000 also goes on about how hard
conventional boilers are to keep efficient.

Any thoughts? Thanks.
