what is differnece in performance, lifetime, etc. between weil mclain boilers and vailant? these are the two used ones i can buy that are of appropriate size for my house and im trying to decide which one.
I prefer the Weil McLain but nothing agenst the other. Proper installation is wayyyy more important than brand. The best boiler installed wrong is crap. The cheepest boiler installed great is the best heat you have ever had.
