    Air compressor cooling with hydronic baseboard elements

    Modine 75k Hot Dawg Vent Pipe

    When I built my garage in 2004 I installed the Modine heater in a corner. At the time the walls were just studs, no insulation or drywall. Figured I'd get to that sometime later. It's now 2018 and I just got around to finishing the interior. When installing it I upsized the vent pipe to 5"...
