The house I live in now is my family home which I remodeled in 1995 after my mother passed away. I had a boiler that was about 5ft square removed and installed a Weil Mclain that was about 1/4th the size. Still to this day no major issues, just a few electronic controls replaced over the years. My burner guy says it's fine and no reason to change it but I did just replace my indirect water heater after 23 years.
The only thing I regret is not switching to gas back in 1995 as there is a gas line in the street. I'm hoping I'm not there long enough for another boiler change.
I built the house behind me back in 1984 and installed an HB Smith boiler and the guy just replaced it a few years ago.
Both, my brother inlaw and my best friend, had the gas fired wall hung units installed within the past 5 years and have had nothing but problems with them every winter. One had to be completely changed under warrantee and the both have gone through a few circuit board changes.
