stainless steel (ss) circulating pump for Hardy wood furnace.
Be aware that the manufacturer now installs the ss pump on all it's
assemblies due to problems with electrolysis and the reduction of the
life span of the entire assembly caused by the cast pumps previously
installed (red and green). The only recommended pump for the Hardy
furnace is the stainless pump. Don't reduce your furnace life span by
saving $100 (or less) on a pump! Unit carries full one year Hardy warranty.
