1 pipe steam pipe through uninsulated joist
I’d like to add a small radiator to my 1 pipe steam system on an elevated porch that has exposed floor joists. Would having ~1’ (quick 90 degree fitting) of runout exposed to the elements be an issue assuming it is pitched correctly? I’ll eventually get it insulated but wondering if I could get through the winter as is (Boston). My thinking is the pipes are hot enough for the condensate to return without freezing, and at below freezing the boiler is running once an hour anyways.
