9. Boiling Tank Heating Element
Once all other factors have been eliminated or checked, have an authorized
service center check that the proper heating element has been installed in your
distiller. Always replace heating elements with the manufacturers supplied
heating elements. Other elements are available from hardware stores, home
repair centers etc. and look like the same element but they are almost always not
the same. Even if the voltage and wattage are the same, they usually have
different wattage densities and most likely different element sheath materials,
which will result in premature heater burnout in continuous water distillation of
raw water. These heating elements will also likely affect you water distillation
capacity.
10. Combination of the above Factors.
Often a reduced water distiller’s production is a combination of many or all of the
above factors. To ensure maximum production from your water distiller, keep
your water distiller clean and operate it in a well-ventilated area and use room
temperature feed water where possible.
