Many years ago, I bought a heater form my Saeco that was universal for all Lubrisizers. It is simply a piece of aluminum plate about 3/8th inch thick. It had a little aluminum box with a cord running out for power. Over the years, the little box came loose and finally fell off.
Inside that little box was a little girl's play iron (clothes iron) with the handle removed and the rheostat protruding through a hole in the little box.
As I recall, I paid a goodly sum for this inovative idea.
Where does one get Heating Tape? The rheostat on my little Iron has pooped out.
