Stop in for a cup of coffee

Good Morning agin, Scamper, Tom, anyone else hangin around.
Gotta agree that heater thing makes no sense. I was thinking flow control, usually vac or cable control (not sure what you are working on) But, that would not have heat in the hose up to the core. At most it might have warm hoses part way up from some mixing. But I would expect the same from a blocked core. If hoses are hot to the core and it has flow. then add me to the :wtf:club.
