Replacing a 17 year old HB Smith boiler.
Old boiler was 4 section, we are downsizing to 3 sections..

We've narrowed the choice down to 2 quotes (out of 4 quotes). A Weil McClain
WTGO-3 or for about $350 more a Dunkirk Ultimate Cast Iron Model PFO3T...
Both would have tankless water heater.

Both would use a Beckett model AFG burner.

Any info on these boilers or boiler replacement in general would be greatly
appreciated.
