    2004 and still going greatReview by punisher
    tech just tuned up furnace for thirteen time in thirteen years good to go great investment (Posted on 9/15/2014)
    Steer clearReview by ed
    My "first" WTGO-3 developed a crack in the cast iron boiler after just six years. The company rep mentioned a design flaw at the time. They did replace the unit but refused to pay the labor charges, claiming that it wasn't "professionally" installed. I had installed the original unit. No problems, yet, with the replacement but failing after such a short time and making me cover labor costs left me a bit sour about Weil Mclain products. (Posted on 5/19/2012)
