The new one is small 75,000 btu, Weil Mclain uses the same packaging for all of their units so it looks biger then it is. The old unit was over 60 years old. The firebox lining was cracked and it leaked from multiple places. I’m doing a refurb so I can’t have something like that around. The new controls are high tech but I won’t be depending on it after emp. It has 86% efficiency.
Material costs about 2500 with new stack, auto air vent, auto feed, expansion tank and a new piece of 1.25 pipe +fittings. No labor costs. I had to spend an extra $65. for a new tube cutter that would go up to 1.25″.
