Finally got enough help to put the Harman in the cellar. Took some work just to get the old wood, oil, coal hot air combo and ducts all out. Next came the install of the 7/8" radiant PEX that didn't want to bend into the 16" bays because it's only about 50 degrees in the cellar. Should have put that radiant up in July when it would have been easier to bend. Just organizing the fittings and such to install. Have to move the old electric tank out of the way to make room for the back up used Liberty. Plan is to connect both boilers separately to the Smart 100 that I want to use for a buffer tank and the DHW. I have pumps for each boiler and a Stainless Grundfos for the Smart to pump to a 50 plate HX for both radiant and higher temp radiators and baseboard. Maybe in a week or two the Harman can be fired up to supply some radiant at least.
