Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

  The heater on a Jensen 25 is an immersion heater (I call it a cartridge heater) and
the resistance measures in the low 30's ohms.  I think mine runs at about 400 watts.
Nothing listed on the base.  Very fast heater for a 2.5" boiler.  Check it out.



Good Luck,
Wayne

That’s a nice engine Wayne! I like the old ones without the reversing gear. The reversing gear on the present engines puts a good bit of drag on them. I prefer a slip eccentric myself.
