5. Heating Element and Boiler Cleanliness
As the water distiller removes impurities some of the impurities may cling to the
boiler tank and the heating element. Any of this scale may build up around the
heating element and actually insulate it, which will drastically decrease the
thermal efficiency of the heating element and require more time/energy to boil
water, which will decrease the water production.
6. Altitude
The water distiller is rated at the altitude of the manufacturer, which is
approximately 675 m (2214 ft) above sea level. Locations lower than this (closer
to sea level) will have reduced water production due to the higher boiling point of
water at higher atmospheric pressures at lower altitudes.
7. Operating Time, Warm-up Period & Suitable Storage
When checking the water distiller production, the start time should be when the
first few drops of water have entered the charcoal filter canister. Do not start
timing when the distiller turns on as it takes a few minutes for the heating
element, boiler tank and water to heat up. The distiller production rating does
NOT account for this time, but rather the continuous production after the distiller
is up to temperature. Ensure when checking production that you have suitable
water storage for holding the amount of water that will be produced.
8. Manual Fill Boiling Tank Fill Level
When checking the water distillation production on manual fill water distillers, the
amount of water initially poured into the boiling tank will affect the production.
Water should be filled to the water level pin so that once the water is hot the
maximum amount of water can be distilled without having to heat up and refill.
Under-filling the boiler will decrease the amount of water distilled. Again, the
warm-up time should not be included in the production rate.
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 your 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.
