220volts/600watts...doesn't that equate to 110volts/300watts?

Then, you ought to check the resistance - how many ohms?

It is not exact but ohms in the 30's will give about 300-400 watts
(less ohms is more power).  If the wattage is anything less than that
it is tricky.  Some engines will run w/250watts (A B43 I have runs
on a bit more than 200watts, go figure) but most need more.

FYI - I use cartridge heaters for horizontal boilers and for vertical
boilers band heaters.  Heaters from China are not always accurate in
the wattage noted in the description.  I have a dud box.

Whatever way you go keep in mind you need to make sure the heating
element can transfer its power to the boiler.  Homemade heat-sinks
are a must.  A strong naked heating element will burn itself out.
Incandescent, even!

Good Luck,
