Installed this Munchkin about 8 years ago at my cousins house with the intent to install the Indirect soon after, well we finally got the chance to install it yesterday.
My cousins house had the original gravity hot water system, no circulator, old boiler was not the original. We ripped out the entire system for the future removal of the chimney that runs on the interior through the kids bedroom closet. Wanted more room in the closet. We installed fin tube baseboard in each room and will eventually do some In floor radiant on the first floor.
