[Shop-talk] hydronic heat retrofit?

FWIW, what I did was make an entirely new run, all the way back to the
furnace. Worked out quite well, and I still don't know what that white stuff
was.  Cut a new hole in the furnace thimble; Home Depot sells the metal
fitting that goes into the hole, plus pre-insulated ductwork and everything
else.  Even the high-temperature caulking compound.

But I still plan to install a direct infrared ceiling fixture in the tiled
shower room with a timer so it can't be accidentally left on.  Feels good to
have the infrared helping dry you after a shower, but I don't want to pay to
keep it on all the time.  Been using a portable infrared fixture ("quartz
tube") for nearly 20 years, it's time to replace it <G>
