How does the Weil McLain GV-90 differ from the GV-90+ on the current Weil McLain webpage?

Also, how does the Weil McLain GV90 compare with other brands regarding longevity, maintenance/repairs, customer satisfaction, costs and adequate heat/hot water when used with an indirect tank?

    Not sure of differences, tech support at WM will fill you in. WM is one of the great American Boiler companies. You cannot go wrong...and I'm generally a Burnham Man.  Mad Dog 🐕

    20 to 30 years you may develop a O ring leak ... And at least one vent fan replaced.

    There was an error rendering this rich post.

    We were told by a potential installer that they stopped using Weil McLain high efficiency boilers due to numerous problems, although the problems weren’t identified. Would appreciate knowing if others have had similar firsthand problems with direct vent, cast iron high efficiency boilers, especially Weil McLain?
