    Why? It will never be as comfortable as the radiator...............

    wasn't my first choice. I had intended to keep it. I'm in the process of adding a shed dormer to increase usable square footage on attic and adding closed cell foam insulation.  This closed cell is amazing and turns out stays between 65 and 85f up there with windows closed, no radiator or ac on in attic but attic door open to rest of house.  We're adding mini split to rest of house for ac and decided on a hyper heat system given recent spiking fuel oil prices (gives me flexibility between heat pump or oil fired steam for lowest cost heating).  I was going to just move the radiator from it's currently center of floor location to a nearby window but once I saw what a hack job the installers did to the 2x8 joists in the 1960s when they added the radiator, I couldn't find a clean way to route the 1 1/4" pipe with proper pitch another 8' through multiple joists.

    Why not use a different radiator?

    How tall is the present one? This will tell us its capacity.

    32" tall.   With the 3 column, 10 section, I calculated last year at 45 EDR.   The real challenge is i'm finding it hard to route the 1 1/4" lateral run under the floor with enough pitch and not diminishing the strength of too many more 2x8 floor joists.
