10 Factors That Will Affect Your Water Distiller
Production
1. Water Volume Measurement
a) How are you measuring your water? The most accurate is by weight.
1 litre of pure water = 1 kg = 1000 g = 2.2046 lbs
b) Water distillers are rated in US gallons, NOT Imperial Gallons.
1 US Gallon = 3.785 litres = 3.785 kg = 8.344 lbs = 0.833 Imp. Gallons
c) Most distilled water holding tanks do not completely drain from the tap.
Ensure this volume of water is included in your calculation by completely
draining the tank or starting your production check with this volume pre-
filled.
2. Line Voltage
The line voltage at the outlet where the distiller is connected should be checked
with a voltmeter. Line voltage is often much less than expected, especially in
rural areas. Line voltage will also usually drop off dramatically when the daily
commercial load hits the grid from approximately 8 am to 5 pm (often when the
distiller owner is not home and unable to check the line voltage). Line voltage
lower than the distiller rated voltage (on the serial plate) will drastically lower the
water production.
3. Fill Water Temperature
The water used to fill the machine may affect the water production. Cooler fill
water will take more time/energy to heat to the boiling point than hot water.
4. Ambient Air Temperature
Water distillers with cooling fans must have sufficient ventilation so that the
boiled steam can be cooled and condensed into distilled water. Restriction of air
flow (such as a closed cupboard) will result in a hot ambient air build up which
will not allow all of the steam to condense into distilled water and some water
production may escape as steam into the atmosphere through the charcoal filter
or volatile gas release vent. This steam loss can also occur in hot summer
periods or very warm climates.
