I went to look at a job that was put in a few years ago, its got everything, cast rads in the old section, baseboard fin and radiant in the new. Complete disaster!
The boiler was installed a few years ago also, Burnham cast iron 170k ,its about a 100k over sized. Question is ...How do you guys feel about removing burners to down fire this beast. PROS...CONS AND TECHNIQUES ?
I wouldn't do it under any circumstance. If you do, you own it and all the ramifications that come with it. It's illegal to modify the gas train in a manner not approved by the manufacturer and AGA. I'm sure Tim can give better specifics.
I'd look at a buffer tank or a properly sized boiler.
You can choose to do what you want, but you cannot choose the consequences.
